Unlicensed Spectrum. New Opportunities, New Challenges
08.11.17.
Wifi, WiGig, IoT, LTE-U, LAA, LBT, 5G, ISM, UNII, and more. Connectivity is exploding. The nicknames and acronyms can be confusing. Meanwhile, more of the devices we buy and use are communicating using unlicensed or light-licensed spectrum.
.
First, what do we mean by spectrum? In these cases, we’re referring to radio frequency (RF). In the natural world, electromagnetic waves are all around us. They’re defined by frequency, ranging from 3 kHz to Gamma rays. In the late 19th century, Guglielmo Marconi first perfected the art of harnessing these waves as “carriers” that could take information quickly from one place to the next with the use of modulation (transmit) and de-modulation (receive). (1)
.
Throughout the world, and specifically in developed countries, governmental agencies manage the use of radio spectrum for communications.(2) Without getting too deep into the technical, the US has two classes of managed spectrum: licensed and unlicensed. Unlicensed frequencies here are 900 MHz, 2.4 GHz, 5.8 GHz, 24 GHz, and 60 GHz. Most WiFi operates at 2.4 GHz, though newer routers have a 5.8 GHz channel as well. WiGig (60 GHz) is beginning to take hold but is still a nascent technology.
.
New Opportunities – IoT, M2M
.
As devices operating in this unlicensed space become less expensive and more ubiquitous, this is a boon to everyone from consumers to enterprises. Think everything from home security and monitoring with footage delivered to your smartphone to industrial farms implementing zero-waste irrigation and fertilization practices through environmental monitoring and machine learning analysis. This proliferation is quickly changing the way we interact with and understand the world around us. It’s an exciting time. However, with many devices transmitting data on the same carrier signal, they can adversely affect each other’s performance. In the industry, this is referred to as interference. Analyzing how these devices interact in the real world is difficult to do, and we’ll look at this next.
.
The Challenges
.
There are two main roadblocks to efficiently measuring and mitigating interference.
.
Economics - the price of many IoT devices is now well below $500 at retail. Building a test lab for reference designs can easily reach into the 7-figure range. That investment makes sense when designing a low-cost product that you’ll build millions of. Recreating the lab test set up for real-world test is a cost-prohibitive endeavor.
.
Logistics - expensive lab equipment is generally quite large and not very mobile friendly. Shipping is costly, raises the risk of damage, and due to the size of lab equipment - field deployment becomes quite tricky, if not impossible.
.
A Better Way
To address both these concerns, SAF has developed a line of ultra-compact, rugged, and affordable spectrum analyzers. Spectrum Compact is an easy to use physical layer test tool with an intuitive GUI, standalone functionality for real time insight, and the ability to continuously record months of spectrum data on the device itself. The included software makes post-measurement analysis and reporting simple, and firmware updates are included for life. Battery life is over 3 hours, so external power is not a concern. SAF offers measurement solutions from 2-87 GHz. Check out www.saftehnika.com for more information.

Handheld V-Band Spectrum Analyzer for 56 to 67 GHz
17.10.17.
Rising demand for bandwidth is driving the growth in deployment of point to point radios in the 60 GHz band (V-Band). V-Band is unlicensed in the U.S. and serves as a complement to the unlicensed 5.8 GHz band. The unique characteristics of the signal allow for dense deployments using small cell or picocell technology.
Deployment in V-Band presents some unique challenges. Because signals in that frequency are susceptible to both atmospheric and rain attenuation, link distances are limited to 500 to 700 m (1600 to 2200 ft). With a 5 mm wavelength, unobstructed line of sight, careful link planning, and proper antenna alignment are essential to ensure that link budgets are met. Until now, there have been no convenient tools to perform these tasks. Reference solutions available on the market today are large, complex, and quite expensive.
In addition to data backhaul, The Wi-Fi Alliance has begun certifying devices for 60 GHz WI-Fi, or WiGig. The Alliance established a well-tried interoperability test bed for device certification. However, a portable solution for physical layer testing in deployed environments that is able to provide real-time information has so far been unavailable. So, the options have been limited to bringing large lab standards into the environment or using a screen-less portable spectrum analyzer and analyzing all the data in a post-processing environment.
SAF Tehnika has addressed these issues with the introduction of the J0SSAP60 Spectrum Compact spectrum analyzer with a frequency range of 56 to 67 GHz. This is the latest addition to the Spectrum Compact family that already covers 2 to 40 GHz and 70 to 87 GHz.
.
Characteristics
As the first handheld spectrum analyzer on the market covering the 56 to 67 GHz frequency bands, it enables microwave engineers to observe what’s going on in real time. It does not use an external down-converter but works directly with V-Band frequencies. The J0SSAP60 has a fixed 10 MHz resolution bandwidth (RBW) and a guaranteed noise floor of -90 dBm.
It comes with a wide beam sniffer antenna that can be attached to the waveguide flange (WR 12) located on the back panel of the analyzer. The scan speed of 0.5 seconds at 1 GHz span and the level of system gain make this spectrum analyzer suitable for interference detection, free channel investigation, tower inspections from ground level, and environmental mapping for indoor environments.
Learn more about Spectrum Compact V-Band and E-band analyzers here: https://saftehnika.com/en/ebandspectrumcompact
The instrument can be used by mobile operators and private network owners in the planning stage to avoid interference adversely affecting the performance of a link upon installation. For regulatory authorities, it’s a great asset for gaining insight into the traffic levels and potential interference challenges in the band. The receiver’s high sensitivity allows users to perform tower inspections from the ground. For Wi-Fi engineers deploying WiGig, the Spectrum Compact offers the ability to fully map the space and use the unit’s 4 GB of memory to save an almost unlimited number of spectrum traces for later analysis and reporting.
Once a system is deployed, a report of the signal density and propagation can be generated using the Spectrum Manager software that is included. In established environments, interference or signal loss caused by rogue RF or unwanted absorption can be investigated and remedied. Like the entire Spectrum Compact range, the J0SSAP60 is designed specifically for comfortable use for extended periods of time in a variety of challenging environments.

Being battery powered the instrument is suitable for microwave radio engineers performing equipment installation, link troubleshooting or gathering data for planning purposes. A key feature of the spectrum analyzer is its form factor – dimensions of the device are similar to those of a cell phone.
.
Field operation
Figure 2 The standard kit includes the spectrum analyzer and a small wide angle horn antenna.
Instead of focusing on features that would only be useful in a laboratory environment the Spectrum Compact has the qualities and functionality needed by microwave field engineers to efficiently perform their daily tasks: radio parameter verification, antenna alignment, interference and multipath detection, power in-band measurements, link troubleshooting and saving the spectrum traces for reports and later analysis.
The analyzer utilizes a resistive touchscreen, allowing operation while wearing gloves. The unit’s high sensitivity and low noise floor enable field engineers to detect exceptionally weak signals, which makes it possible to do multiple measurements from the ground level and carry out link troubleshooting without site traffic interruptions.
A standard kit includes the spectrum analyzer and a small wide-angle horn antenna. The V-Band antenna can be attached to a WR 12 waveguide flange at the back of the spectrum analyzer, enabling detection and visualization of the incoming signal just by pointing it towards the transmitting radio.
The J0SSAP60 is housed in a rugged dust and splash resistant IP54 rated enclosure. A weatherproof, dedicated DC charging socket enables fast charging, and a fully charged unit has up to three hours of battery life.

Why 23 million Americans don't have fast internet
28.09.17.
A lot has changed in the past couple of years. In a matter of seconds, you can stream the newest content on Netflix, you can send disappearing photos of yourself looking like a panda, and the talks about 5G being just around the corner are more and more frequent. It's pretty exciting, to say the least. Truth is - some people don't even have access to 3G, let alone 4G internet connection. In fact, more than a half of the world's population don't have any access to the internet. Let that sink in. Having the option to watch Netflix and use Snapchat whenever you want is great, but having access to a stable and reliable internet connection means way more than that. The Internet is a crucial part of our education and healthcare system. We understand the importance of having a reliable network, that is why we ensure that our products and solutions are of top quality.
We have a lot of experience of deploying links in rural areas and we wholeheartedly believe that wireless can decrease the number by a large amount allowing Internet access to people who previously had it denied.
Spectrum scans as a requirement for spectrum applicants
27.09.17.
When it comes to spectrum monitoring and regulation, authorities in different countries have significantly varying approaches. In some countries, regulators are state-financed and act upon request or complaints, and are not forced to earn their living. In some countries, while state-owned, regulators act more like commercial business entities in terms of earning their budgets by not only licensing, but also by monitoring spectrum and punishing “spectrum pirates” – users that deploy radios without permission, sometimes interfering with other spectrum users, slowing network speeds and causing costly network downtimes.
Despite those differences in approaches, all regulators have a single mission and same challenges – to keep networks and frequencies well-organized avoiding overcrowding and interferences as well as detecting and punishing unlicensed users.
Lately, we stumbled upon increasing demand for our world’s smallest field spectrum analyzers in Malaysia. As it turns out, Malaysia recently introduced 23 GHz frequency channel previously unavailable for public commercial use. In order to make this channel introduction well-organized, MCMC also introduced a new requirement for spectrum users.
.
Whenever somebody wants to apply for spectrum, he needs to provide a full RF spectrum scan according to parameters intended for a particular link and showing that desired channel is free and won’t interfere with other network users.
.
By this simple yet effective measure, MCMC has been able to maintain well-organized spectrum deployments with minimum efforts and expenses. Customers are happy too because they are able to deploy networks as effectively as possible without worrying about interferences and unlicensed spectrum users.
.
As described by one of SAF distributors in Malaysia, Numero Engineering Sdn. Bhd. CEO HL Chan, first impression with Spectrum Compact was surprising in terms of seeing such small device with -105dBm noise floor.
.
“Handheld spectrum analyzers can’t achieve such a good noise floor unless the sweep time in minutes range with RBW is so narrow where it’s of no practical use, but this device does it just right! Battery life is very good and the user interface is easy to use. What’s most impressive – it makes impressive reports!”
.
Currently, Malaysia with its fairly small land-area has become one of the main markets for Spectrum Compact, but we’ve also seen similar approaches being implemented by regulators in other countries as well. It seems that spectrum scans performed by the customer or by regulator upon customer’s request are becoming a common practice in increasing number of countries worldwide.
This month read about our low latency solutions, how Spectrum Compact can be used in civil and military aviation, and how a simple thing like a name badge can tell you a lot about our company's cornerstones.
By the time you finish reading this sentence, you could earn a few million dollars. If you were a stock market trading company, that is. For stock market traders any second counts that's why they choose our solutions for their low latency projects. Read more

How a portable spectrum analyzer can lower telemetry tracking equipment downtime
21.08.17.
For flight test in civil and military aviation and heavy weaponry tests, it is crucial to receive important data in real time, to analyze flight characteristics and health status during the test. To receive this data, usually, telemetry tracking antennas are used.
Well-designed tracking antennas like the WTW-LS series from WTW Anlagenbau allow a smooth and easy transfer of crucial data from the flying object to the ground control station even if they are moving fast or operating several kilometers away from the ground station.
These flight or weaponry tests are usually men, time and cost-intensive, so any problem with the telemetric system that might occur during the test has to be solved fast and efficiently. Here the spectrum analyzer, Spectrum Compact, from SAF Tehnika is a real game-changer. Spectrum Compact is deployed and ready for measurement within seconds. The device is specifically designed for the field use and easy to operate, so also technicians unfamiliar with spectrum analyzers can use Spectrum Compact easily.

Caution: money traveling in ultra high speed | From Frankfurt to London
16.08.17.
Following our vision to deliver Customized Microwave Solutions we have helped to complete numerous innovative projects all around the world and this latest one has truly been a paradigm changer. The common practice to link financial institutions and exchanges has been to replace existing technologies with fiber optic cables to ensure the best speed and reliability for mission-critical applications. This case study shows that a microwave-based alternative is not only possible but that it is the most suitable option under the current market conditions.
The common axiom in math is that the shortest point between two locations is a straight line. With microwave radios, it’s possible to create a straighter path as microwave is not beholden to existing right of ways or obstructions like rivers while guaranteeing significantly lower latency than fiber optics or any other cable solution.
.
Customer

Challenge
Sometimes the difference between success and failure in business can be measured in mere milliseconds, making ultra-fast data transaction crucial for profit. That is why the creation of a new low-latency microwave connection between the New York Stock Exchange (NYSE Euronext) Basildondatacenter in UK and the Equinix data center in Frankfurt (Germany) was designed.Reliable carrier grade equipment with >35 Year MTBF Experience and knowledge in building low latency networks Exceptionally fast delivery time Ability to take on the responsibility of the project’s management and supervision SAF developed a fully customizable solution according to the specifications and needs of the project. CCMW was looking for the best and most innovative partner for the co-development of this highly challenging solution. SAF Tehnika engineers co-designed the microwave links spanning four different countries and connecting two coasts of the North Sea and provided on-site supervision of the project, fully tailored to CCMW’s specific needs.
Solution
The microwave connection between Basildon and Frankfurt has 13 fixed points, with the longest link reaching 107 kilometers (66 miles). It was accomplished by including SAF Active Repeaters between our Lumina radios thus significantly increasing the distance between links but keeping latency as low as possible. The North Sea crossing is bridged by installing antennas mounted at a height of 200 meters (656 feet). SAF Tehnika together with CCMW provided shared low latency connectivity between London and Frankfurt to accommodate high-frequency trading on the trading platforms of both financial hubs. Stock market traders who are the users of this service are now benefitting from a trading speed improvement of up to 40%.

Quality RF Tools for the Budget Conscious
28.07.17.
It's important to introduce your engineering students to the fundamentals of RF analysis, but the tools out there are either expensive or of such low quality that they wouldn't last a semester in a hands-on engineering lab. There are incredible tools out there from Keysight, Anritsu, and Rohde & Schwarz, but the cost of these can be quite prohibitive for the average university. The initial investment in these lab-grade tools is high with acquisition costs reaching six-figures. The cost to repair them if a student accidentally blows up the front end can easily exceed $10,000.00. On the other end, there are extremely inexpensive solutions that knock-off the established players, but they tend to be fragile and are not built to last.
.
I was meeting with a customer this week who's interested in SAF's Spectrum Compact as a tool for his EMC lab. The draws of the Spectrum Compact for him are the cost, the form factor, its instant-on functionality, and an easy-to-use software that's included for post-processing and reporting.
.
As he said, "I can just keep this on my desk and use it for some basic work without waiting 10 minutes for it to boot up."
.
Further on in our conversation, we were discussing applications for education and this former professor was lamenting the fact that this wasn't available when he was outfitting his EE lab.
.
Everything that SAF's engineering team built into these products that makes them ideal for outdoor microwave path alignment, link troubleshooting and maintenance, also makes perfect tools for introduction to RF basics. The Compact line of analyzers and generators are simple to use with just 9 buttons. They're quite accurate (+/- 3 dB), sensitive, (-105 dBm), and have great thermal stability (-15°C to +55°C).
.
Their deep memory (4 GB) allows the user to save thousands of traces for post-processing/analysis and the units are housed in a rugged anodized aluminum case that's built to take a lot of physical abuse. As for frequency ranges, we have solutions from 2-87 GHz.

Large size antenna alignment (Part 3 of 3)
20.07.17.
This blog post explains large (6ft/1.8m and larger) size antenna alignment. As mentioned in the previous blog post, the main difficulty in aligning these antennas lies in finding the initial signal and doing the final fine tuning.
.
In order to understand why it is difficult to find the initial signal, we have to look at the radiation pattern of large size antennas. Additionally, we have to remember that, typically, larger antennas are used for links that are at least 40 kilometers/25 miles long.
.
As an example, one of the longest links with SAF Tehnika radios is 148 kilometers /92 miles. There are definitely quite a few links that are longer than that.
.
For our example, I have chosen the Commscope 8ft/2.4m UHP8-59W-D3A antenna. Its beamwidth is just 1.6 degrees and the gain is 41dBi. From the radiation pattern (pictured below) we can see that this antenna, similarly to any other large size high performance antenna, has no prominent side lobes. At a 10 degree angle from the main lobe, this antenna has just a +5dBi amplification, and it drops to -4dBi at a 15 degree angle. With that, it is clear that this antenna requires a very precise and smooth alignment.
UHP8-59W-D3A radiation pattern envelope
.
Imagine that two of these antennas are installed at least 50 kilometres / 31 miles from each other, and need to be aligned with 0.5 degree precision using a wrench mechanism to turn the antenna based on the RSSI readings on a voltmeter. This could potentially result in a very long alignment process and/or incorrect alignment. Here are the two main issues to keep in mind:
You have two antennas with a very narrow beamwidth, so the first, and most challenging, issue will be to precisely point each of them to the tower on the opposite side of the link.
RSSI readings are limited by the radio sensitivity and management refresh time. This means that, most probably, you will only see a change in the voltmeter reading if the antenna is aligned on the main lobe. It is important to note that if you sweep the antenna too quickly or with steps that are too large, you will skip over the main beam and will not be able to align the antennas at all.
.
How would a spectrum analyzer with an additional antenna help?
.
The key element here is the sensitivity and the reading speed of the spectrum analyzer. In my previous blog post, we covered the fact that spectrum analyzers have a better sensitivity than radios and, therefore, finding a side lobe (in case of small antennas) or the initial signal (for large antennas) is much easier. In other words, during a sweep of the antenna, you will be able to see the signal in a larger sweep region than you would with an RSSI measurement.
Comparison of antenna sweep area using different alignment methods
.
Now, let us get back to the previously mentioned 50 kilometer / 31 mile link.
We now have a spectrum analyzer with a sensitivity that is better than that of the radio. This will help us spot the signal much quicker and, due to the faster scanning speed, it will be easier to understand how the antenna sweep affects the received signal level. This is already a step up from what we had with the radios, but while it does solve the second issue and somewhat remedies the first, it will still take some time to properly align the antennas.
.
From our perspective, the best solution to the first issue is to use a small size directional wide antenna. For this purpose, SAF uses a 20dBi 14 degree wide antenna. Since the spectrum analyzer has a significantly better sensitivity than a radio, it is still possible to detect the signal from the far side despite using a smaller antenna. It is much easier to align the far side antenna to this small wide beamwidth antenna, which allows you to align it to the correct position on the tower. Once that is done, you just connect the spectrum analyzer to the large antenna and fine tune it as was described in the previous blog post. This approach will be much easier and less time consuming than the traditional alignment with RSSI readings.

PtP antenna alignment using spectrum analyzer (part 2 of 3)
27.05.17.
In my previous blog post about point-to-point antenna alignment, I wrote about some best case practices of doing so with the classic method – RSSI alignment. Here, I’ll describe a different, more effective way of aligning antennas, regardless of their size. This method involves using a spectrum analyzer.
.
Naturally, some of you will object, saying that spectrum analyzers for point-to-point radio frequencies are very expensive and are an unnecessary luxury item. With that in mind, SAF Tehnika has created an affordable series of spectrum analyzers, which are the smallest (pocket sized) standalone devices in the world. You can find more information here: https://saftehnika.com/en/spectrumanalyzer.
.
However, this post isn’t intended as a commercial for a specific product – nearly any spectrum analyzer can be used for antenna alignment. The difference between analyzers will be in how easy, fast, and convenient the process is.
First, we have to remember why it is important to properly align antennas, and that each missing dB can play a role in link performance, especially in regards to the SLA that is agreed with the customer. Every missed dB will increase annual link downtime and decrease its availability, which can be a drawback for potential customers, whether you are a service provider, mobile operator, or an installation and maintenance company.
.
In general, there are two potential issues when aligning antennas. First – when aligning small antennas, it is difficult to avoid the side lobes. Second – with larger antennas (6ft/1.8m and more), the difficulty lies in finding the initial signal.
.
How does a spectrum analyzer help in resolving these two issues? I will give examples using the Spectrum Compact, a spectrum analyzer manufactured by SAF Tehnika.
.
A spectrum analyzer is an instrument used to measure the magnitude of the signal versus frequency. In other words, if the received signal level is -50dBm, the radio interface will display only this number, while a spectrum analyzer will show the shape and strength of the signal. An example is given below.
A key parameter of any antenna is its radiation pattern. It describes how the antenna will transmit the signal. Looking at the radiation pattern, it is immediately clear that the signal propagates in multiple paths (directions). These paths are called lobes. Each antenna has a main lobe and several side lobes. The difference in amplification (signal strength) between the main lobe and side lobes is typically around 20 dB. This, of course, varies with antenna size, frequency, and class. Small antennas in low frequencies typically have strong side lobes, which sometimes results in installation crews aligning the antenna on a side lobe instead of the main lobe.
.
When an antenna sweep is performed and an initial signal is found, installers typically stick with this first signal and do not continue the antenna sweep. If this initial signal happens to be a side lobe, the antenna will most likely be aligned to it, resulting in poor link performance. Performing the initial antenna sweep with a voltmeter or by using the radio’s built-in indicators will only give you a number value, without any idea of what signal the antenna is being aligned to. Accuracy of the Voltmeter (RSSI) method depends on the accuracy of the radio itself, its user interface refresh speed and sensitivity level.
.
Benefits of using a Spectrum Compact (spectrum analyzer) include:
A better receiver sensitivity than a radio has, making it possible to quickly spot the initial signal
Better sweep speed/refresh rate, which makes for faster antenna sweeps
EMC protection and precision of a test and measurement device – these results can be used as proof of any potential issues
Better resolution – it is possible to identify and align to the correct signal. Radios typically have wide receiver filters, so the power reading values can be affected by adjacent channels
Visual representation of the signal. This helps to determine potential issues, such as reflections, interference, and damaged hardware
Signal level is measured in dBm – there is no need to convert voltage to dBm
.
Nearly every spectrum analyzer, including Spectrum Compact, comes with multiple possible trace modes. The displayed data will depend on the chosen trace mode. For example, “max hold” trace mode will add another spectrum curve on the screen, displaying the maximum achieved signal strength in this trace mode. This is very helpful in antenna alignment, as you no longer need to memorize the highest achieved signal levels, with them being displayed on the screen after a full antenna sweep. In order to align the antenna on the main lobe, you just have to turn it back until the real-time reading matches the previously registered “max hold” curve. In addition to that, you will also be able to verify that there is no interference and that the antenna is not aligned on a reflected signal.
.
Let me give you an example of a spectrum curve of a properly aligned antenna, along with a “max hold” trace on the screen. From the picture, you can see that:
The real-time reading (white line) matches the “max hold” curve (blue line)
Top of the signal is even without any notches or spikes. This means that there are no reflections, hardware failures, or unexpected fading
Adjacent channels do not have any signals, so the spectrum is clear and the installed link should not suffer from any interference issues
In order to determine the absolute power of the signal, it is necessary to use the Spectrum Compact’s “power in band” function. In other spectrum analyzers, the function might also be called “channel power measurement”. This is a mathematical function that sums all the separate spectrum energy points and provides the absolute power level of the signal. In other words, the absolute power level is the number that shows up in the radio management graphical interface and is provided in link budget calculations.
Here is another example, showing how a spectrum analyzer can help to identify issues with radio signal propagation during the installation process. We can see that the “power in band” value matches the link budget calculation, but the signal curve is damaged.
.
This phenomenon does not affect the power values, but definitely affects the signal to noise ratio, so the link would not be able to perform as expected. If the classic voltmeter method was used, this would not be noticed during the installation and the troubleshooting team would have to return to the site to find this problem.
In my next post, I will share a similar approach for aligning larger antennas by using a spectrum analyzer and a reference antenna!
Critical Communications World Exhibition Highlights
18.05.17.
Trade shows are a great opportunity to meet new people from different businesses and learn about their needs and requirements for various projects.
As for the mission critical communications, reliability, experience and knowledge are the key factors. Customers tend to be less concerned about the price, instead, they need a solution that won't fail unexpectedly.
.
They are also less concerned about parameters that are seen as the most crucial for other industries. For example, TETRA networks require relatively low capacity while link distance often exceeds several dozen miles. Luckily, our Marathon II allows reaching up to 100 km distances while maintaining up to 43Mbps capacity.
The CCW exhibition was a great success for SAF - lots of new leads, excellent impressions and many new business opportunities in the region.

Tele2 Link Troubleshooting Using Spectrum Compact
27.04.17.
Interference is one of the most common issues that mobile operators have to face. The root cause of insufficient performance can vary significantly, starting from factors that can’t be prevented by a field engineer, such as weather conditions, and ending with issues that can be easily altered with the right equipment in hand. Mobile operator Tele2 faced an issue with one of their links and chose SAF services for link troubleshooting.
“In the fast-paced business in which Tele2 operates, every action has to be completed as fast as possible. With the right equipment, we can make sure that all systems are up and running 24/7” Liga Krumina CTO, Tele2
Customer
Tele2 Latvia has been one of the leading mobile operators in Latvia since the year 2000. With its headquarters in Stockholm, Sweden, Tele2 Latvia is part of a larger organization Tele2 AB Group which provides telecommunication services to more than 14 million customers in 9 European countries. Tele2 Latvia offers the fastest and broadest 4G coverage in Latvia making it available to 98% of the population. With more than 250 employees, Tele2 Latvia continuously works on expanding their infrastructure to offer high quality products and services.
Tele2 link
MW link: Sauriesi - Skirotava
Link distance: 11.5km (7.1 miles)
Frequency: 8GHz
Capacity: 380 Mbps (with XPIC)
Antenna diameter: 0.6m (2ft)
Challenge
Tele2 had an issue with insufficient XPIC link performance that remained even after changing the equipment. The link was operating solely in 1+0 configuration and had a high BER value and experienced radio frame loss in its Horizontal polarization branch when XPIC was enabled. Since the equipment was not faulty, Tele2 in cooperation with SAF did advanced troubleshooting.
"Spectrum Compact is efficient and effective at the same time. The troubleshooting saved us time and was done from the ground level which made it exceptionally convenient for our field engineers." Liga Krumina CTO, Tele2
Solution
After some additional analysis, it was determined that this is most likely a problem with the radio transmission path. Due to its high sensitivity and compact form factor, Spectrum Compact was chosen as the most fitting tool to solve this issue. Troubleshooting was done from the ground level where, after doing the initial scan to verify the transmission frequencies on the tower, it was detected that there was a high and low radio violation. The cause of interference was a low side radio that was transmitting in the adjacent frequency channel to Tele2’s high side radio on the same tower, interfering testing link from the back side of the antenna. After detecting this problem, it was advised to switch the placement of high and low radios, which would resolve the issue completely. Thanks to the Spectrum Compact, this issue was resolved in a few hours.
Point-to-point antenna alignment (part 1 of 3)
26.04.17.
Part 1. Conventional antenna alignment
.
One of the most important stages of installing a microwave point-to-point link is proper alignment of the antenna system. Any misalignment can cause unstable operation and will decrease the link budget that will affect the overall reliability of the link. While usually straight-forward, alignment on some links can be time-consuming and frustrating if not done correctly. This article will address the alignment challenges sometimes met by engineers and provide general instructions and techniques for achieving optimal link performance. Before you install the microwave radio system, know:
What is your target Received signal level (also RSSI voltage) from link budget calculation? Typically, the target receive signal level in the field is within +/- 3dB of the theoretical value.
Azimuth and elevation angles for alignment, e.g. from Pathloss link budget.
Be methodical. Alignment should be seen as two stage process: coarse alignment and fine alignment. Vertical plane alignment (up/down-tilting) is the most challenging.
.
For coarse alignment, approximate the antenna direction by using Google Earth (or equivalent) to align with a landmark located close to your antenna location in direction to remote side antenna (for instance, a mountain, building, etc.). If you are building a link in an area with few landmarks, a self-made landmark such as kite, balloon, floodlight, flare, or reflection from a mirror might help. A compass or GPS can be another useful tool (noting the difference between True and Magnetic bearings). When using a compass, be aware that large metal structures such as a tower will distort compass readings.
.
Fine Alignment is normally done using RSSI voltage output port from the radio.
Points to consider:
Ensure radios are fully set-up and tested on the bench before taking them into the field
Start by disabling ACM and ATPC and configuring both radios in accordance with link budget (Tx power, modulation, frequency channel). After successful pre-calculated Rx level achievement , ou can enable ACM and ATPC as required
If possible have a team at each end. It is frustrating and time consuming to travel between the two sites, as the alignment process requires a lot of back and forth
Only adjust one side of the link at a time
Be aware of mistaken antenna alignment on a side lobe. Try to push past the best received signal. Radiation patterns incorporate smaller side lobes, in addition to a much larger main lobe. If your received signal is 20dB or lower than your calculated RSL, you may have found a side lobe. Continue sweeping slowly beyond that lobe to see if you can find the main lobe
Agree on antenna polarization. It can be frustrating to attempt aligning the antenna only to discover that the other team is using the opposite polarization. Do not forget of 17/24 GHz band radios cross-polarization requirement. This should be agreed upon before starting the alignment. If Rx levels remain stubbornly weak, a double check doesn't hurt. Typically radios unintentionally cross-polarized will show a signal loss of 20 - 30dB or greater.
MW point to point system must have a clear radio line of sight. Even if the remote site has clear eye visibility, radio line of sight is defined by the Fresnel Zone. The Fresnel zone for a radio beam is an elliptical area immediately surrounding the visual path. It varies in width depending on the length of the signal path and the frequency of the signal. If a hard object, such as a mountain ridge or building, is too close to the signal path, it can reduce strength of the radio signal and desired Rx level will not be achieved. This happens even though the obstacle does not obscure the direct, visual line of sight. The necessary clearance for the Fresnel zone can be calculated, and it must be taken into account when designing the link
During short link alignment over urban areas try to avoid alignment to reflected signal from a reflective plane such as a rooftop or lake in the middle of the path. In order to avoid such mistake, always start Vertical plane sweep from top, meaning antenna should be aligned “into the sky” before you begin.
