The National Science Foundation (NSF) has operated the United States Antarctic Program (USAP) since its inception in the 1950s. Program scientists perform a variety of critical research projects there that rely heavily on communications with the outside world—for transmission of research data for analysis, for contact with other researchers in the U.S. and other regions of the world, for personal communications between the Antarctica staff and their families and others, and for many other purposes.

Chugach Electric’s network migration began in 2010, when they first identified upcoming issues with their existing network, which consisted of end-of-life hardware and capacity bottlenecks. The migration was critical to ensure traffic across operations that covered an expansive footprint remained flowing and without any issues and to be also to evolve the network to enable allow future technologies, services, and applications.

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.

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.

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.

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.

LTE mobile connectivity now exists in many more urban places than not. Virtually all big cities have multiple choices for LTE and most have at least one choice for LTE Advanced—the real 4G wireless. For example, you can see iPhone and Android users taking advantage of all this high-capacity coverage as they leisurely view high-definition YouTube videos without buffering and actually livestream major league sports in cafes, parks and just walking around at lunch.

In Austria, people love their coffee, and they love their Internet. WLAN provider NETcompany makes sure they get both, with high-speed wireless access via hotspots at cafés and other popular places with the help of microwave networking.
Serving a core business clientele of home and business customers, NETcompany offers wireless Internet connections in fixed applications. In addition, the company builds and provides wireless Internet access points, also known as wifi hotspots, to cafés, hotels and other mostly tourism-related establishments
Around two years ago, Aviat Networks began working with the wireless Internet service provider to connect its point-to-multipoint base stations, which aggregate the business and residential wireless traffic, to its main communications infrastructure via a backbone based on Eclipse microwave radios. In addition, hotspot traffic is also transported over the backbone network.
Apparently, business has been increasing over the course of time. Thus, more advanced networking services and higher capacity are required to keep up with wireless Internet demand from the customers of NETcompany’s customers.
Therefore, NETcompany became interested in the Layer 2 capabilities of the CTR 8540 and its more robust Carrier Ethernet features. In addition, the higher QAM modulations supported by the CTR 8540 enable higher airlink capacities for aggregating traffic than are available in traditional microwave radio. Now the WLAN provider’s backbone is supported by a series of CTR 8540 microwave routers that deliver high-capacity backhaul capability.
This early CTR 8540 customer is already deploying high-capacity links in 2+0 configurations. Aviat continues to work with NETcompany and other customers with vertical applications. Read about other early CTR 8540 scenarios and let us know about your microwave networking application.

Since the beginning of October 2014, there has been a lot of coverage in the technology press concerning the so-called “Shellshock” or “Bash Bug” computer vulnerability. All the coverage has been exclusively related to general IT and computer systems. But how does this vulnerability concern microwave radio systems? Take our poll and let us know what you know.
Aviat Networks recently completed an exhaustive internal review of all our current and legacy products and found no inherent weaknesses in any of the systems toward Shellshock. We have recently informed our customers of this end result (see statement).
