Both Eclipse and the IRU 600 offer market-leading solutions to network operators who need robust, flexible features such as extra high power (EHP), hybrid transport of TDM and IP traffic, superior system gain, and the latest security technologies.
In both products, the enhancements consist of new firmware added to existing modules. The firmware is a highly efficient way to enable true native transport of both TDM and IP traffic. It’s like having two radios (from two different technology eras) moving traffic seamlessly across the same network expanse—without the cost of two radio systems and with easy, cost-effective new ways to migrate your network to current transport technologies over time.
Cisco routers remain the backbone of internet connections worldwide. Deep in the heart of networks, core routers perform the essential plumbing of the web. Further out on the edges, access routers provide connectivity for mobile devices via microwave radios (many of which are Eclipse radios from Aviat Networks). Generally, routers assume a full 1 Gbps bandwidth capability between Layer 2 connections provided by microwave radios.
However, modulation and channel size selections can vary the actual bandwidth between 1 Mbps and 1000 Mbps (i.e., 1 Gbps). This can also happen when Adaptive Coding Modulation (ACM) is activated on a point-to-point microwave link and the link’s bandwidth varies based on propagation conditions. If congestion occurs on the link, the router cannot quickly prioritize traffic nor select the optimal path, resulting in possible “black holing” of critical traffic.
The public safety market has relied for many years on Aviat Networks to be a supplier of mission-critical microwave backhaul equipment. For example, since the introduction of the Eclipse microwave radio a few years ago, it has been received very successfully in the Australia public safety market. In the last five years, Aviat has sold and deployed thousands of radios (i.e., TRs) in the public safety and life critical radio ecosystem.
“The cutting-edge Gigabit Ethernet and IP capabilities of Eclipse were critical for Australia government agencies,” says Raj Kumar, vice president, sales and services, Asia Pacific, Aviat Networks. “As radio sites rolled out across Australia, Eclipse has enabled efficient deployment of multiple radio carriers in a single chassis—a mission-critical advantage for the simulcast trunking sites.”
Just this February, Ncell, the leading mobile provider in Nepal, awarded Aviat Networks an Appreciation Certificate for successfully migrating its existing VSAT network to high-speed Eclipse microwave radio. This project was executed in the Himalaya range at an average attitude of 4,410 meters above sea level with three passive repeater links. Included in this rollout is a 99 km microwave link.
According to Ncell, this is the world’s highest 3G rollout. As a result, this upgrade is considered a feather in Ncell’s hat.
While Aviat Networks has completed many successful projects with Ncell, this one is worth a special mention. Awarded in 2013, this project has helped Aviat establish itself as a key Ncell vendor for the access network. The implementation includes equipment and services.

Dick Laine, longtime principal engineer for Aviat Networks, delivers one of his patented presentations on microwave networking during an installment of the video blog Radio Head Technology Series.
Microwave radios come and microwave radios go, but the sage advice of Aviat Networks Principal Engineer, Dick Laine, has no end-of-life. In our seventh installment of the very popular video blog Radio Head Technology Series Dick talks about the diversity of diversity schemes and other protection methods available to microwave networking engineers.
Using examples from the radio legacy of Aviat Networks (e.g., Constellation, MegaStar—you must remember these, it hasn’t been that long) and our current microwave networking solutions (e.g., Eclipse, TRuepoint 6500, WTM 6000) he expounds on the past, present and future of protection. From Angle Diversity (one of the earliest diversity schemes used in Line-of-Sight digital microwave) to Hybrid Diversity (HD) and Frequency Diversity (that need licensing waivers to be used in many applications) to comparisons of fiber-like protection methods, Dick covers it all. For example, did you know that a four-dish HD antenna arrangement offers little to no performance improvement over a three-dish HD configuration?
So with free registration to the video series you can have the benefit of all of Dick’s wisdom and nonpareil presentation style on Diversity. You get access to all the earlier videos, too. (Did we mention there are six previous episodes?) And the presentation slides. And the podcast. And all for FREE! Wow!

Balancing cost and performance is a tough act for most operators dealing with telecom networking, especially when it comes to equipment procurement. Getting all the bells and whistles can sometimes result in having a lot of options to choose from. Often times microwave users have to juggle with a variety of radio options that suit a particular site requirement, for example, having to select between low power or high power radios to meet varying distance or system throughput/gain needs. Depending on location and licensing requirements, this may even translate into different products types for different frequency bands. More products result in more spares to maintain in inventory, along with added support and maintenance, inevitably leading to higher costs.
To help address this challenge, Aviat recently unveiled the industry’s first universal outdoor unit (ODU) to support software- defined base and high power modes in a single ODU, with Aviat’s unique Flexible Power Mode (FPM) capability. FPM allows operators to optimize both cost and performance, minimizing their overall total cost of ownership, by paying for the power they need only when needed. As a result, operators can procure a single ODU for multiple locations and via a simple software licensing mechanism, remotely adjust the transmit output power to meet the needs of a particular site. No need to spare multiple radios, nor deal with the operational burden of managing and supporting a variety of product options.
Additionally, operators can apply this flexibility to migrate from legacy low power, low capacity radios to a high power and performance ODU to support much greater link throughput, without having to change their installed antennas. This minimizes both their CAPEX and OPEX while migrating their network from a legacy low capacity TDM microwave link to a high speed Ethernet one.
So while juggling may still be a well needed skill to survive in Telecom, Aviat is reducing the load when it comes to microwave networking. Click here to find out more.

Here at Aviat Networks we are focused on everything that is wireless transmission. With so much happening in the wireless industry, we wanted to join in the conversation and share our experiences and insights on the trends, technology, and business.
If you are reading this inaugural blog post it is likely we have a lot in common. While the main purpose of this blog is to talk about wireless transmission, we will also cover topics such as network evolution, software usability, services, and more.
Our initial blog posts will cover topics leading up to Mobile World Congress 2011. Over the course of the next three weeks, we will offer timely coverage and video excerpts from the show to keep you up-to-speed on the latest and greatest.
We encourage you to be part of the conversation since just hearing from us would be like having a conversation with ourselves. New viewpoints and constructive feedback are always welcome and we looking forward to hearing from you!
