Fixing Microwave Software Licenses: From Agony to Ecstasy

In the world of wireless backhaul, software licensing on microwave radio remains the same as always. Fundamentally, little has changed over the years. You need a separate license for almost every software component—capacity, feature and, in some cases, port licenses. Too many and more coming! Continue reading

Three Elements to IP/MPLS Success in the Microwave Access

In microwave communications—as in all electronic communications mediums—operators trend toward the latest technologies (e.g., IP/MPLS). They all have conditioning to think that newer is better. And by and large that’s right.

However, when it comes to IP/MPLS—one of the most advanced packet technologies—you need to handle this concept with care. Especially in a mixed infrastructure that includes microwave, fiber and other potential backhaul transport. Continue reading

SDN in the Backhaul: All About Reducing OPEX

Figure 1: SDN will not significantly reduce microwave CAPEX costs.

Software-defined networking (SDN) promises to drastically simplify how transport networks deploy, operate and get serviced. Reducing OPEX remains a significant factor for implementing software-defined networking. Automating service creation, traffic and bandwidth control, and network management as well as reducing maintenance complexity of routing protocols remain areas where it will simplify backhaul and lower OPEX. The only questions seem, “When will this happen?” and “How much will it save?” And what about CAPEX? Can we expect reduction in purchase price of microwave backhaul based on such a migration?

Without becoming reality, 5G mobile communications have already captured the imagination of operators and technology providers. So can the general public catch up with the hype soon? We’ll see. Meantime, behind-the-scenes mechanics of prepping for 5G continue, building on prior technologies. At each step of the evolution of backhaul infrastructure, different challenges cropped up.

Case Study: Longest Microwave Link in a Mobile Phone Network

longest-microwave-link-site-viewRecently, the longest microwave link (189 km) ever turned up in a public mobile phone network went live in Tonga. It’s part of operator Digicel’s Pacific network. Engineers at Aviat Networks thrive on challenges. We go farther for our customers—in products, service and distance. For example, Aviat Networks previously implemented a very long all-IP backhaul connection across 193 km of open water in Central America for a private network application. Continue reading

SDN in the Backhaul: 4 Takeaways for a 5G World

Ola Gustafsson SDN backhaul expert for Aviat Networks.

Aviat Networks Chief Product Officer Ola Gustafsson talks about SDN 5G backhaul during AfricaCom 2016.

The most pressing business need in many networks deals with delivery of new services.The biggest evolution today in the backhaul network is the trend toward integration of IP/MPLS intelligence into microwave. Software-defined networking (SDN) remains another more recent trend in backhaul. However, as we’ve posted many times, integration of IP/MPLS intelligence into microwave systems provides a number of benefits. These include lower cost, fewer boxes to buy/deploy/maintain and better network performance overall such as lower latency and better reliability. Continue reading
