Papua New Guinea, or PNG, is one half of the island of New Guinea, along with offshore islands, located in the South Pacific immediately to the north of the Australian continent. The country is rugged and heavily covered by dense rainforest, which presents enormous challenges when it comes to establishing a national communications infrastructure. In most cases, deploying fiber routes is simply not practical nor affordable. Wireless is the only answer in these cases.

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.
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.

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.
The point of this post is to determine the amount of latency reduction possible with a one box integrated microwave router solution when compared to a two-box (separate router + microwave) offering. By how much does the one box solution improve latency?
Latency is important to all network operators. The lower the end-to-end delay the better it is for all types of applications.
For example latency is critically important to mobile network operators (MNOs) for LTE Advanced features like coordinated multi-point (COMP) and MIMO, which require extremely tight latency. CRAN architectures are also demanding tighter latency from the backhaul.
In addition, for latency sensitive applications like Teleprotection, SCADA and simulcast in private markets such as public safety, utilities and the federal government will greatly benefit from lower latency network performance. For other customers, lower latency is critical for synchronization and HD video transport.

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.
With the goal of a hyper-meshed 5G street level network, clearly today’s small cell deployments represent just an interim phase in a progressive network densification—pushing the network outward. This means today’s small cell sites will become tomorrow’s macrocells, or hub sites.
Future-looking mobile operators have planned for this eventuality. In the developed world, small cell and the Internet of Things (IoT) drive mobile network densification. However, in the developing world the primary goal of enterprise connectivity spurs network densification, due to lack of wireline infrastructure to business buildings. The end result of network densification is the same.
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!
