Adaptive Media Awareness - microwave routing White paper: Adaptive Media Awareness - microwave routing
Microwave networks are unique. Unlike fiber, copper, or any other Layer 1 transport technology, non-standard and dynamically changing bandwidths along with complex link aggregation and protection schemes make microwave networks complex and different. Regular routers are not designed for microwave networks and are inefficient and ill-suited to handle traffic in such a network. They rely on slow, protocol-based notifications to gather data from the underlying transport network to optimize their behavior. This lack of an adaptive media awareness negatively impacts network performance, reliability and operations costs significantly.

How an Integrated Microwave-IP/MPLS Solution Reduces Latency

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.

Getting it Done! Aviat & Australia Public Safety Networks

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.”

Adaptive Media Awareness: Making Layer 3 Microwave Aware

In many wireless networks, transport engineering looks after the microwave radio function while the IT department has domain over IP equipment. These two organizations started independently and grew separately over many years. It did not seem that there was any problem with this arrangement.

However, it led to the selection of equipment—radios and routers—that worked really well on their own but had no awareness of one another. Not surprisingly, these technology solutions did not perform together optimally.

Aviat Networks-RFS 4G case study
How Microwave Networking Enables Nationwide 4G

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.

Case for IP/MPLS Routers at the Small Cell…but not Just any Router!

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.

3 Ways to Get Smart About Nodal Microwave

At a time in the not-so-distant past, there was only one way to implement microwave radio: one radio link per microwave terminal. Did not matter what type of link it concerned: protected, non-protected or multi-channel. From the advent of digital microwave radio in the 1980s and 1990s, terminals typically had no options for integration of co-located telecom devices. And to interconnect muxes or switches required external cabling and possibly a patch-panel.

Then in the early 2000s, so-called “nodal” radios came into vogue. Designed to address the drawbacks of the one-radio-one-link paradigm, a single microwave radio node could serve as a platform for multiple links. There were still limitations when it came to radio and switch interactions, but multiple sources of traffic could now be integrated and connected on the nodal platform.

Layer 3 intelligence: cell sites need more than dumb pipes

Once upon a time, cell sites served as little more than passive pass-throughs for phone calls and text messages. Because voice calls and SMS posts did not require much wireless capacity cell sites did not require very robust provisioning. Now that the Internet has gone fully mobile with streaming videos and real-time applications such as VoLTE and IPTV regularly crushing network capacity design parameters, the time to get smart about backhaul and access traffic has arrived. The time for Layer 3 intelligence is now.

In fact, for some time mobile cell sites have transitioned from simple Layer 2 connected sites for 1990s-style mobile phone and data access to multipurpose centers for delivering new, smart device services. However, they can only provide new, smart services if they are built upon Layer 3 technology that offers intelligent handling of wireless traffic. Only IP routing technology is capable of such functionality.

But here comes the catch regarding IP routers providing Layer 3 intelligence at the cell site. With more than 50 percent of the wireless traffic in the world going to and coming from mobile sites through backhaul radio, Layer 3 intelligence must have awareness of microwave networking. And regular routers just do not offer microwave awareness. A new class of device must fill the void left by regular routers that frankly do not have enough “smarts” to deliver Layer 3 intelligence for cell sites that depend on microwave backhaul. A device that combines the best attributes of microwave radios and IP routers.

To provide a closer examination of this issue, Aviat Networks has authored a new white paper—no registration required—that makes the case for Layer 3 intelligence at the cell site. And how to implement a new class of “smart” devices that enable microwave radio awareness with IP routing.

WLAN Provider uses Microwave Networking for Backbone

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.

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!
