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
—even campsites.

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.

IP/MPLS: Coming to a Village near you

Whether the local police department responding to a burglary call or firefighters putting out a blaze in the historic district, first responders across America rely on mission-critical communications infrastructure to provide timely, reliable and secure voice, video and data services to do the job.

In our data-infused, mobile and Internet-connected world, public safety agencies have come to realize that upgrading infrastructure to IP/MPLS technology is the best way to lower costs and provide rich services in a scalable way, while enabling effective communication with peer local, state and federal organizations. Access to high volumes of data and the ability to share it with key stakeholders allows public safety professionals to make rapid decisions and speed up actions.

IP/MPLS and Microwave: Better Together
At Aviat Networks, we have blazed a path to IP in privately operated networks with our hybrid IP/TDM microwave radios, which efficiently converge packet-based traffic with legacy TDM. This solution gives public safety network operators a concurrence of technology while migration decisions and investments are made.

Recently, Aviat introduced the term “microwave routing” with the launch of its CTR platform. At its core, microwave routing is about integrating IP/MPLS capability into the microwave layer to increase transport intelligence while decreasing cost and complexity. As part of its portfolio, Aviat features the highly resilient CTR 8611 microwave router, which has been designed to meet the needs of public safety agencies today and tomorrow—addressing a future that is sure to include LTE/LTE-Advanced technology and a vast new buildout of advanced networking infrastructure ushered in by the FirstNet initiative.

IP/MPLS in Action
One example of IP/MPLS in public safety networks can be found in the Northeastern United States, where a major statewide public safety agency recently adopted IP/MPLS functionality in its backhaul. This deployment is based on the CTR 8611 and ProVision network management system (NMS). ProVision, with its new INM package, provides a smarter end-to-end, point-and-click IP/MPLS service management solution.

Armed with these tools, this public safety agency turned up a complete IP/MPLS solution for its mission-critical networks, which includes microwave radios, microwave routers and network management. Aviat supports the agency with turnkey services to simplify the network design, install and commission equipment and provide post-deployment support.

IP/MPLS for Everyone
Since 1999, IP/MPLS has been deployed in the mainstream of networking. Until now, its implementation has largely been the domain of wireline telephone companies and more recently mobile operators. However, we now see private network operators adopt IP/MPLS technology because of its superiority and economic benefits. Although IP/MPLS is not something that is perceptible by the ordinary citizen, its positive impact on our daily lives is significant. We Heart IP/MPLS!

Your Network Deserves Better than a Regular Router

Mobile network operators (MNOs) continue to reap the windfall of the widespread adoption of smartphones. Mobile data volumes spiked initially and still rise quarter over quarter. Along with the demand for more data throughput from their subscribers, MNOs have to accommodate the greater need for responsiveness closer to the network edge.

While regular routers are good at serving Layer 3 services to mobile users on fiber-heavy backhaul networks, they do not do a very efficient job of servicing mobile backhaul networks that primarily use microwave radio. As it turns out, the worldwide majority of mobile backhaul networks are still based on microwave technology, as regularly updated industry research shows.

What can an MNO with microwave backhaul do to bring Layer 3 functionality to its customers that will handle bandwidth constraints, unique aspects of translating router protocols across the microwave interface and failure detection and recovery, among others?

Aviat Networks has published an article in Mobile World magazine that looks at these challenges of regular routers when used in a microwave backhaul network and proposes possible solutions.

Converged Microwave Traffic Emerges in Africa

In South Africa, as in many emerging markets, wireless backhaul has long been a proverbial bottleneck to network growth. Due to cost and logistics, fiber optic technology remains out of reach as a practical solution for most aggregation scenarios, save for urban applications where population density and shorter routes can justify the exorbitance.

Now with the advent of higher speed, higher throughput mobile phones and tablet PCs, higher-order networking technologies are being pressed into service. Standard microwave radio, while cost efficient and effective for crossing far-flung forests, monumental mountains and desiccated deserts with traditional payload such as voice calls and moderate data rate applications, was not designed for the connectivity and capacity requirements of Layer 3 services. Thus, the bottleneck has grown still narrower. Even to the point where standard microwave radio might be hitting its upper threshold for serving mobile broadband.

Technical marketing manager, Siphiwe Nelwamondo, recently sat down with Engineering News, to discuss these issues and the present and future of microwave radio backhaul in South Africa and across the continent. In addition, he delved into how microwave networking is bridging the radio-IP gap for Layer 3 services by running IP/MPLS protocols on converged microwave routers.

As more and more mobile services get pushed out to the edge of the access network, the imperative for Layer 3 will only grow. Even as 3.5G and 4G mobile users who depend on full-IP increase in number, a majority of second- and third-generation subscribers will continue to rely on circuit-based technology. Not to worry, Nelwamondo covers how TDM telephony will be supported in a converged microwave and IP environment.

The full article goes on to discuss how mobile operators will strategize providing enterprise services from the cellular base station with microwave networking, virtual routers and more.

Wireless Transmission blog 2014 in review

Aviat Networks had WordPress prepare a 2014 annual report for the official blog of Wireless Transmission. What follows is a summary of the highlights from the year that saw the launch of microwave networking.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. The Aviat blog was viewed about 40,000 times in 2014. If it were a concert at Sydney Opera House, it would take about 15 sold-out performances for that many people to see it.
