Why the Eclipse Hybrid Native TDM/ IP support is still relevant in a 5G World

As the Telecom world largely focuses on the 5G future, many operators are still managing mission-critical operations that use traditional TDM microwave radios. Legacy SCADA, push-to-talk, teleprotection, radar systems, and other vital operations rely on TDM for its simplicity, stability and low latency. However, legacy TDM microwave networks are not able to easily support high capacity Ethernet/IP applications.

Utility companies, public safety operators with legacy TDM-based P25 networks, and service providers that are still operating 2G base stations (in sub-saharan Africa 3G/4G connections only just surpassed 2G in 2019, according to the GSMA) or that need to deliver low-latency TDM enterprise connections, all need to maintain a cost effective TDM network infrastructure while also supporting high speed Ethernet/IP for next generation service deployments.

The Challenge of Migrating from all-TDM to IP

Many operators have delayed migration of their TDM networks to IP due to the large investment needed in time, labor, and network downtime. There are solutions such as pseudowires that enable TDM to be transported over an IP network, but they add latency and inefficiencies in the conversion process that can impact the operation of critical applications such as teleprotection. Operators need a hybrid network solution with the capability to manage TDM and IP separately and efficiently, but over the same link to minimize disruptions and reduce the cost of migrating to IP.

Support for both mission critical TDM and IP applications

Most operators looking to deploy 5G are facing the same problem. Their legacy transport and backhaul infrastructure designed for 3G/4G cannot support the high capacity demands of 5G and upgrading their networks requires large investments in time and infrastructure. As more 5G networks are rolled out, limited company resources can become strained in what seems like an endless flow of cash and time. In addition, the complexity of these projects causes delays and ultimately deadlines to be missed.

The Challenge of 5G

The major challenge operators are facing as they are looking to upgrade to 5G is that current methods to significantly increase link capacity can involve expensive equipment upgrades and long installation projects. This can have devastating effects on profitability and competitiveness in the race to build the next generation network, especially for the smaller operator.

Aviat’s Simple Solution

At Aviat, we have gained an understanding of the challenges operators face when deploying 5G networks by working hand in hand with our customers. That’s how we knew the industry needed a solution that could take an existing 4G backhaul and add significant capacity without significantly impacting the bottom line.

Our solution is simple, a Vendor Agnostic Multi-Band, or MB-VA overlay. This works by overlaying a new high-capacity E-Band or Multi-Band on top of the existing microwave link to add up to 10 Gbps per link. Deploying Aviat’s MB-VA saves the initial investment on the existing backhaul, reduces the expense of upgrading microwave, and reduces operational expenses while preparing your network for the 5G future.

Looking at the big picture – how to lower your Wireless Backhaul TCO

Planning a microwave 5G project is time consuming and requires skills from several different disciplines. Investing in microwave equipment that reliably delivers high-capacity internet with minimal maintenance and operational costs is crucial to maximizing the anticipated return on investment (ROI). This requires project planners to have a high technical ability and a strong business acumen including a clear understanding of the cost drivers applicable to their network.

A common mistake when anticipating ROI for 5G equipment is only considering the purchase and installation costs. Future expenses also need to be considered to understand what the total cost of ownership (TCO) is. Without knowing the TCO, the estimated ROI cannot be calculated correctly. An incorrect ROI will result in a misleading higher anticipated profitability, not accounting for major future expenses.

Anticipated ROI = (Lifetime Expected Revenues/ Lifetime Expected Expenses)*100
TCO = Initial CAPEX + Initial OPEX + Future CAPEX + Future OPEX

The table below illustrates expenses that are considered when planning a microwave project.

Initial CAPEXInitial OPEXFuture CAPEXFuture OPEX
Hardware – radio, antenna and other accessoriesSite/path surveys and Link designHardware upgradesAnnual Spectrum license fees
Tower engineering and strengthening (if needed)Spectrum license application and initial feeMobilization and Installation costsTower lease fees (radio, and antenna) if applicable
Shipping and storage costsAntenna upgrade costs (if needed)Maintenance, cost of reliability (truck rolls, repair/replacement)
Mobilization and Installation costsCapacity upgrade and other feature licensesPower costs

Initial CAPEX/OPEX and 5G Projects

As the demand for 5G speed increases, it’s creating a wireless gold rush of vendors and budget “5G capable” equipment that promise high-capacity solutions at a low initial price (CAPEX). However, the equipment is either low capacity and will need additional hardware to scale or is software limited requiring expensive licenses to unlock capacity and features. Often, budget equipment becomes a “you get what you pay for situation.” They advertise “pay as your grow” but it quickly becomes “pay more later”. These additional operating expenses add up over the lifetime of the equipment reducing ROI.
In the example below, based on the initial CAPEX Vendor B appears to be the better business decision. It’s $5,000 dollars less. It’s $5,000 on the purchase date but will it still be such a value in 5 years?

Figure 1: Choosing the right vendor solution to lower your transport and access network TCO
Figure 1: Choosing the right vendor solution

Future CAPEX/OPEXs for Microwave 5G Projects

Many vendors are not upfront with TCO. They count on the allure of a low starting price and busy professionals not always doing their homework. Their customers only realize how expensive it is to upgrade when its time to scale capacity or add new features. At that point the buyers only have two options, rip and replace or pay the higher upgrade costs. Other considerations can also drive significant ongoing operational costs, such as increased tower lease costs to support larger antennas, or higher recurring spectrum fees.
Below is an example of the 5-year TCO from Vendor A. The total of CAPEX and OPEX over 5 years is $6,580. With the addition of the initial CAPEX the TCO of vendor A is $21,580.

Figure 2: Vendor A 5-year microwave network TCO
Figure 2: Vendor A 5-year TCO

Now compare this with the 5-year TCO of vendor B. Notice the anticipated CAPEX and OPEX is much higher at $22,822, resulting in a TCO of $32,822. Why is Vendor B’s TCO $11,242 higher than Vendor A’s? Vendor A’s equipment was able to increase capacity with minimum investment, compared to Vendor B which required additional planning, licenses, and hardware to increase capacity. If you were to multiply the effort and expense to scale across an entire network then Vendor B quickly goes from Hero to Zero if overall TCO is a key part of planning your 5G microwave network.Figure 3: Vendor B 5-year microwave network TCO
Figure 3: Vendor B 5-year TCO

Unexpected Expenses

Capacity upgrades like the example above are easily accounted for in TCO but budget equipment can incur unexpected OPEX/ OPEX too. To keep their prices low, budget vendors will cut corners. A common source of expenses with budget equipment is their half-baked management software and poorly designed hardware with a lower MTBF. When the software or hardware fails so does the network, resulting in service interruption and expensive truck rolls.

Aviat Industrialized Private LTE

Aviat’s Private LTE solution is designed for operators looking for the right combination of cost, coverage, resiliency and convenience. Unlike many solutions on the market, Aviat Private LTE is designed for smaller-scale industrial applications, with easy deploy and right-sized elements that fit your need without breaking the bank.

In contrast, commercial LTE solutions are designed for much larger networks, and may not be suitable for the extremely harsh environments found in remote mines, for example. Commercial LTE is also not designed to be Mission Critical, providing the high level of resilience against failure. In short, you can end up paying more for s solution which is not fit for purpose.

How do we do it? Let’s break it down:
Aviat advantage from the Core, Backhaul to the Base Station:

Aviat Industrialized Private LTE

The power of a macro in a small cell footprint

Our RDL 6000 base station provides similar geographic coverage as a typical LTE marco cell, but in a much smaller all-outdoor footprint. This means less equipment, fewer cables, faster installation and no outdoor cabinet. On top of that it is hardened to withstand the toughest conditions and temperature extremes.

‘Right-Sized’ EPC

Our EPC is sized for enterprise and industrial networks. Others EPC solutions are not, meaning you end up paying exorbitant annual maintenance and other charges. Having an EPC that scales down to fit your network means you save on costs.

Best-in-Class Wireless Backhaul

Aviat is a global leader microwave and millimeter-wave backhaul and transport solutions that bundling best in class features to support high-capacity, low power consumption, built-in IP/MPLS routing, so you can build a backhaul network with the lowest TCO and highest performance.

Save money on capacity upgrades, troubleshooting and outage prevention with Aviat’s Health Assurance Software (HAS)

Do you often upgrade backhaul link capacity only after experiencing network congestion or receiving customer complaints?
Do you often feel overwhelmed with alarms on your management system that are impossible to sort, manage and troubleshoot?

Do you often only realize that a link has a problem when it suffers a complete outage?

If you experience one or more of these issues with your network then Aviat Health Assurance Software can help you.

When we look at the three operational challenges that we introduced above, HAS delivers real, measurable results:

Capacity Planning

Network capacity upgrades are needed on an ongoing basis to meet growing demand and support deployment of new services. Operators need to decide in a timely manner which links need more capacity, instead of congestion issues arising that affects customer quality of service, leading to complaints and churn. Conversely, this also allows operators to avoid over-investing in network capacity that may never be needed, wasting capital.

How HAS can help: A smart list of links that require capacity upgrades, by time.

Takeaway: Smarter capacity upgrades, saving you up to 10% of total CAPEX budget


Operators need to be able to correlate faults from different parts of the network to determine if a service or customer issue is related to (or due to) their microwave backhaul. Before HAS, this was manual and extremely time consuming, and a high level of transport network expertise was required to debug and correlate faults with RAN/Core/IP domains

How HAS can help: HAS Network Navigator pinpoints faults on geographical and site-specific maps to isolate faults and navigate through network segments

Takeaway: Shorter outage times, no unnecessary truck rolls, for a 30% reduction in operating costs.

Outage Prevention

What if you could identify issues before they cause a link outage? Network operations personnel are often faced with a deluge of complex alarms from multiple management systems. Operators again rely on customer complaints to identify outages, or compensate with time-consuming routine manual monitoring of links to identify problems. HAS employs proactive trend analysis to anticipate and prevent outages, resulting in less downtime.

How HAS can help: A ‘Focus List’ of links not meeting a predetermined availability target due to inadequate path design, antenna misalignment, or some other underlying issue.

Takeaway: Proactive identification of problem links, less routine monitoring, resulting in 2x reduction in downtime.

Licensed 6 GHz Links are under threat from all sides

The introduction of Wi-Fi 6E and the push to utilize the 6 GHz spectrum for mobile 5G are presenting increasing interference risk to existing operators using fixed links in the 6 GHz FCC bands.


With the introduction of Wi-Fi 6E and the push to utilize the 6 GHz spectrum for mobile 5G, fixed links operating in the Lower and Upper 6 GHz FCC bands are under increasing threat from interference both from legitimate and rogue operators. The mobile industry is clearly targeting this spectrum for 5G services, seeing it as ‘under-utilized’ and observing that most mobile operators would prefer to reuse this spectrum more efficiently for mobile access and relocate their backhaul links to other frequencies. But where does this leave other operators dependent on 6 GHz for their critical wireless transport links?

In this article we look at one recent instance of interference from an unauthorized use of a point-to-multipoint (PTMP) radio system that was operating in the licensed L6 GHz spectrum that severely impacted the operation of a newly deployed 6 GHz point-to-point (PTP) microwave link, how this was discovered and what steps were taken to resolve it.

This rogue interference was entirely unexpected and was the first time Aviat had encountered such a situation over many decades of deploying radios across the US. The investigation and resolution took many months of intensive work, delaying the commissioning of the links and increasing the project costs significantly.

The Problem

During the deployment of a number of new 6 GHz microwave links for a customer, a US County located in large metro area, Aviat encountered some very peculiar problems. The receiver threshold tests were failing badly, by between 2 and 25 dB, and measurements would vary over time, hour by hour, day by day. Measurements showed a huge threshold degradation, which resulted in a reduced fade margins down to 10 dB, instead of 35 dB as predicted by the link design.

Aviat considered all potential sources of the problem – licensed radio interference, building reflections, misaligned antennas, damaged waveguide, faulty equipment, etc. The radio equipment at each end of the link was even replaced with new radios operating on different frequencies, but the problem got even worse, and persisted for many months.

Some Brief Background on the 6 GHz band

In 2020, the FCC opened 1200 MHz of spectrum in the 6 GHz band (5.925–7.125 GHz) for unlicensed uses, including Wi-Fi 6E and other point-to-multipoint (PTMP) applications. Unlicensed devices will share this spectrum with incumbent licensed services under rules crafted to protect those licensed services and enable both unlicensed and licensed operations to coexist throughout the band. The FCC authorized indoor low-power operations over the full 1200 MHz and standard-power devices in 850 MHz in the 6 GHz band. An Automated Frequency Coordination system (AFC) will prevent standard power access points from operating where they could cause interference to incumbent services.

Licensed 6 GHz Links are under threat from all sides

Although Wi-Fi 6E is not yet authorized for outdoor use, but experimental testing is now underway and bodies like the Wi-Fi Alliance are preparing for what they see as a huge opportunity, while vendors such as Cisco have announced their first outdoor Wi-Fi 6E ready access point.

Meanwhile, the FCCs AFC system is still in development, will give Wi-Fi 6E access points real time instructions on where and how they can operate within the 6 Ghz band (ie: frequency range and power levels), via a direct data link between the access point and the AFC system. AFC is intended to protect incumbent microwave by preventing overlapping frequency usage by Wi-Fi 6E operators, with microwave link operators being given priority.

There is also a small 75 MHz piece of spectrum called the ITS band, which is reserved for radio-based intelligent transportation systems, such as vehicle-to-vehicle and vehicle-to-infrastructure communications. The FCC is also preparing to open 45 MHz of this band to extend the unlicensed band, granting Special Temporary Authority (STA) to use this spectrum, typically for up to 60 days but can be extended for longer periods.

Tracking down the Interference

While Aviat was looking for the cause of the link problems, it was noticed that there was a PTMP access point installed on the same rooftop. Since these systems should not be using the L6 GHz spectrum it was not initially considered a potential source of interference. Checks with the operator of the PTMP system revealed that they in fact were operating in the ITS spectrum using an STA, but also illegally operating in the L6 GHz spectrum which was not allowed by the STA. As it turned out there were numerous other access points deployed in the city by this operator.

Using a spectrum analyzer Aviat was able to confirm that the PTMP AP were operating in L6 band with a frequency hopping 20 MHz channel and a wide beam-width antenna. The PTMP equipment was from a well-known vendor but was operating ‘beta’ software that caused it to operate well outside of the authorized spectrum range. This interference was incredibly hard to pinpoint due to the changing frequency of operation and power.

Measurement of the interference found


Aviat had established that the PTMP operator was unaware that they were illegally using the L6 GHz spectrum, and along with our customer contacted the local FCC office, who sent their own investigators to take measurements that confirmed Aviat’s findings. They then returned 4 weeks later to find that the PTMP system was still operating unchanged. In the meantime, Aviat found a second PTMP system that was operating in L6 GHz spectrum. The FCC is in the process of issuing formal warning letters to each operator to cease operation in the L6 band.

Outdoor Wi-Fi 6E is coming

This case study demonstrates how a rogue PTMP system can have devastating impact on the operation of your 6 GHz links. Microwave radios do not have any countermeasures to mitigate this interference – features like ACM and ATPC do not help.

Aviat now looks for potential 6 GHz PTMP interference as part of the site/link survey, before the link is deployed, however this won’t always protect against PTMP interference at a later date. Additionally outdoor Wi-Fi 6E is coming, which could multiply these issues in practice, as the fear is that there could be many more instances of rogue deployments threatening the operation of your 6 GHz links.

Prevention is better than cure

Aviat has been aware of this threat, and as a result has developed our Frequency Assurance System, or FAS. FAS is specifically developed to monitor, assess and report on PTMP/Wi-Fi 6E interference. It is simple to implement on your existing links without updating hardware or software. FAS can be deployed as a premises or hosted solution, the latter in Aviat’s own Hosted Private Cloud service.

Wi-Fi 6E and PTMP interference is bursty and dynamic, so it is very hard to capture and quantify, but Aviat FAS will detect the interference and predict the likely impact on link operation, whether that be degraded operation or a complete outage. FAS uses onboard analytics to pick problems up, and then present the necessary data in a concise report format, as the FCC often may not have seen such cases before.

In addition to FAS, Aviat can also provide an Interference Diagnostic Service (IDS) to help you categorize, document and understand interference, and to determine how it can be resolved.

If you would like to learn more about 6 GHz interference or request a FAS demo, please contact your Aviat representative.

White Paper: Unleashing the Practical Capability of Multi-Band

By Terry Ross, PLM Director

When considering a Multi-Band solution, users are usually interested in accessing the multi-gigabit high capacities available at the millimetre-wave frequency bands at 80 GHz, supported by the robust operation of microwave radio. A tightly integrated radio solution that provides a seamless single transport interface for users makes Multi-Band a no-brainer for Mobile Service Providers, WISPs and Private Network operators.

So how difficult is it to plan for a Multi-Band solution? A designer has two choices: (1) look at a vendor-agnostic path planning tool like Pathloss and run separate microwave and millimetre-wave path calculations across a given path to work out the best solution; or (2) use an integrated tool like Aviat Design that provides a simultaneous view of the microwave and millimetre-wave performance in a single view. And in this way the user quickly sees what the total realistic capacity is, and what the typical minimum capacity would be when the path degrades to a point where the millimetre-wave is completely lost.

And when it comes to planning, it’s as easy as 99.999%, right? Or 99.995%? In reality, designing to such strict objectives on a Multi-Band link means you will be missing out on most of the benefits!

The key concepts of Multi-Band are:

  1. Utilise the high capacities in millimetre-wave bands
  2. Protect the link operation with robust microwave bands
  3. Deliver a hitless single transport experience to the user
  4. High capacity over longer distances than can be achieved with E-Band alone
  5. Lower Total Cost of Ownership for high-capacity links, particularly operators who pay high microwave spectrum fees.

Let’s look at some best practices for designing a Multi-Band link to get the most out of this technology.

Getting Proactive with Aviat Health Assurance

by Marius Koegelenberg, Product Marketing Manager

Modern telecom networks need very high levels of availability to ensure business continuity whether it be mission critical networks carrying tele protection circuits, land mobile radio or even operator providing the best possible service to their customers.

Traditional approaches to improving Network Reliability

Telecoms network operators are striving to achieve the goal of 99.999% availability on an individual link basis, which translates to a mere 5 minutes of allowed downtime per year. To achieve this many operators add physical equipment protection in the form of N+N configurations and/or space diversity path protection. Techniques like adaptive modulation and automatic transmit power control have proven very successful in achieving more resilient networks by mitigating the adverse effects of radio propagation.

Whilst this protects the hardware and in some cases the path, the network management and monitoring aspect is often overlooked, not understood, or neglected causing operators to only react on active alarms exposing them to possible outages. In some cases, operators struggle with a lack of experienced personnel to be able to understand and prioritize alarms to trace the root cause and identify the corrective actions required.

Predictive Maintenance

In most industries it is well recognized that moving from a reactive approach to network maintenance to a more predictive or proactive model results in a significant improvement in network availability and customer satisfaction. This can also be more cost effective than traditional preventative approaches based on regular or routine maintenance and has been applied in other industries where predictive analytics improve performance by diagnosing up to 95% of issues before they impact operational efficiency, can result in a 2x reduction in downtime, and cut operating costs by an average of 30%.

Moving from a reactive to a more predictive maintenance model dramatically improves network reliability

Latent issues cause more outages

Without proactive and automatic microwave performance monitoring in place many latent issues remain unnoticed for prolonged periods of time, until they turn into problems that result in degraded network performance or at worst an outage. In many cases personnel responsible for the microwave network may not be aware of an issue until they receive a complaint from a customer or some other part of their network organization.

Even if problems do not result in an outcome as serious as an outage, link issues at the very least can often result in the link running at a capacity well below the design criteria, causing traffic congestion that could result in the operator increasing the capacity of the link (and purchasing additional licenses) when it is not needed, wasting their investment.

Assuring Network Health with Aviat HAS

Aviat has addressed these pains with our new Health Assurance Software (or HAS), which is designed specifically to give control back to operators. Creating a proactive/predictive approach to network maintenance with trend analysis, KPI monitoring and placing focus on where operators should be spending time to address network concerns.

Based on our experience and discussions with operators, we believe that HAS can deliver a 10% saving in capacity upgrades, a 2x reduction in downtime, and up to a 30% reduction in operating costs.

HAS is available as either a Aviat Hosted or Managed Service and uniquely simplifies the detection and analysis of RF anomalies and degradation of key performance indicators (KPIs). HAS focuses on 3 main KPI’s namely 1) Availability; 2) Utilization; and 3) Congestion.

HAS includes 7 path anomaly detection algorithms to proactively identify links that are operating in a degraded state:

  • Advanced availability calculations
  • XPIC cancellation
  • Modulation availability
  • Dribbling errors
  • Extended fade
  • Interference
  • Operating in low modulation

Geographical Map

HAS is designed around a highly visual geographical map (geo-map). The Topology view in the map has several filters that allows the user with a single glance to see what is happening in their network. Fault correlation is greatly simplified with this bird’s eye view.

Focus List to pinpoint most critical links

HAS introduces focus lists that provide customers with ranked list of the problematic links they see in the map to help to with where they need to spend their time. A consolidated view shows those links not performing to specification to allow for directed correction of network issues and to ensure ultimate control of which links get corrected first.
