“Pierce County has been and continues to look at Aviat as a strategic partner for day to day operations, problem resolution, system configuration, upgrades and on-going preventive maintenance for our Public Safety infrastructure that support over 23 Law Enforcement and Fire jurisdictions, Regional Transit and over 900,000 citizens.”

This large western US state had a longtime relationship with a microwave radio vendor and would have continued buying from them if their radios and support evolved with the State’s needs. However, over time its needs changed and it had to have more capabilities from its communications network. But it did not want to unnecessarily build new sites and erect costly new towers.Read More
In Australia, the federal government has had an ambitious plan to connect all citizens to a national broadband network (NBN). However, in some of the more remote parts of the country, of which there are more than a few, the incumbent provider, Telstra, cannot deliver that subscriber experience. This leaves it to alternative access providers to fill the gap.
One of these providers, Aviat partner MIMP Connecting Solutions, decided to use Aviat Networks microwave solutions to reach remote customers beyond the NBN fiber footprint. This is important as many vulnerable subscribers need to be connected to doctors, nurses and other healthcare professionals for help. Literally, this can be a matter of life or death.Read More
When designing microwave networks, backhaul engineers have a wide variety of techniques at their disposal. One method that remains highly effective is Space Diversity (SD). With SD, two antennas separated by some distance can increase the availability of a link from something less than 99.999 percent to in excess of five-nines uptime. However, the introduction of a second parabolic antenna on a microwave path poses a substantial increase in the capital expenditure (capex) budget.Read More
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.Read More
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.”Read More
In late January and into February 2016, a big tumult ensued when Sprint announced that it would begin to move its mobile backhaul strategy from one based on leased fiber to another based on owned microwave radio. The story first ran in technology news site Re/code and quickly got reposted with additional commentary by FierceWireless, Wireless Week and others, and which was reiterated this week in RCR Wireless.
While the breathtaking headlines about reducing costs by $1 billion caught most people’s attention—primarily through reducing tower leasing costs and not using competitors’ networks—lower down in the copy came a potent reminder from Sprint about the economic benefits of microwave radio. It also highlighted the fact that backhaul has entered a transitional period (see article end for more on that).
Most of that $1 billion that Sprint seeks to save comes by way of moving away from AT&T and Verizon fiber backhaul networks. You might think that Sprint would build its own fiber network instead. But that would take too long and still have an exorbitant price tag associated with it. It’s a function of both out-of-pocket capital costs and embedded lost opportunity costs. Bottom line: laying fiber connections is expensive and slow. Putting up a network of high-speed, broadband microwave relay towers is quicker and easier.Read More
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.Read More
Here at Aviat Networks we have the privilege of extremely close proximity to the site of Super Bowl 50, at Levi’s Stadium in Santa Clara, California. We are about a half mile away and from our building parking lot we can clearly see the venue where the Carolina Panthers and Denver Broncos will clash for the championship of American professional football.
And while hundreds of millions of Americans and hundreds of millions more people around the world will watch the game raptly on television, 75,000-plus fans at the ballpark will see it in person. Not only will they watch it with their own eyes but also use their iPhones, iPads and Android smart devices to tweet, post YouTube and Vine videos or otherwise cheer or jeer the real-time action of the game on Facebook.
What many don’t know concerns the game within the game: how all this wireless data will get out of the stadium to the mobile service provider networks and finally onto the Internet and social media. As it turns out, Aviat Networks will also have an up-close virtual seat to this tilt of the cellular subscribers vs. their wireless carriers.Read More
