Microwave Networking

The Benefits of a Subscription-Based Upgrade Agreement
It’s not uncommon for public safety agencies to make one-time purchases of microwave technology and then leave the network untouched for years.
Outdated networks can lack the capacity and functionality needed to meet the changing needs of stakeholders and customers. They’re more likely to experience issues as customer services evolve. Recurring updates also ensure continued interoperability with other evolving equipment in the network, further reducing failures.

Segment Routing 101 and the Future of MPLS
By Said Jilani, Sr Customer Solutions Architect
Segment Routing is a new routing paradigm that aims to optimize, simplify, and improve the scalability of IP/MPLS based networks. Segment Routing utilizes source-based routing scheme where a network node steers a packet based on a list of instructions carried in the packet header (called “segments”). The list of segments carried in the packet header provide a strict or a loose specification of the required network path or tunnel eliminating the need for transit nodes to hold and maintain that path/tunnel information.

Multi-Gigabit Microwave Networks
Options and Strategies for Maximizing Your Network Potential
In recent years the microwave industry has made great progress in capacity evolution – actually we’ve seen somewhere in the neighborhood of 30 times increase in microwave capacity over the past 10 years. In doing so, microwave has proven itself to meet the capacity of LTE and LTE-A applications and with some new evolutions to enable multi-gigabit links, is now well positioned for 5G as well.

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.

8 Benefits of Converging Microwave and IP Router Functionality
For a couple years, Aviat Networks has been talking about the benefits of a converged system encompassing the functionality of microwave radios and IP routers to result in a microwave router. Simply known as the Aviat CTR platform, this next-generation microwave router delivers eight key benefits that make designing and implementing a modern backhaul network easier and more cost effective than ever:

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.

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.

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.
