State-Wide Microwave Network Case Study: Extra High Power Radios

State-Wide Microwave Network Case Study: Extra High Power Radios

This large western US state had a longtime relationship with a microwave radio vendor and would have continued buying from them if their radios and support evolved with the State’s needs. However, over time its needs changed and it had to have more capabilities from its communications network. But it did not want to unnecessarily build new sites and erect costly new towers.

Three Elements to IP/MPLS Success in the Microwave Access

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.

We Put the Spotlight on Voice Over LTE (VoLTE)

As one of the most anticipated network technologies, Voice over LTE (VoLTE) has been discussed by operators for years. The expectation was that deployments would start in 2013, but roll-outs in North America were delayed.

Operators have faced a series of issues that include poor voice quality and long call establishment times. Once these problems are solved, it is expected that VoLTE will allow operators to provide  voice and data services using an integrated packet network. As the problems described show, the implementation of VoLTE presents challenges for the entire LTE ecosystem including microwave backhaul.

We have produced a white paper to describe some of the VoLTE requirements that must be met in order to overcome these technical challenges, which must encompass a flexible microwave backhaul as a key factor for a successful transition to all-packet voice and video VoLTE  networks. A brief introduction to VoLTE is presented and then different VoLTE backhaul requirements are described with possible solutions.

Hybrid Microwave for Wireless Network Backhaul Evolution

There is no one-size-fits-all solution for wireless network backhaul. What will work for some operators’ mobile backhaul will not work for others. Many operators have large installed bases of TDM infrastructure, and it is too cost prohibitive to uninstall them wholesale and jump directly to a full IP mobile backhaul. There is going to be a transition period.

The transition period will need a different breed of wireless solutions. Fourth Generation Hybrid or Dual Ethernet/TDM microwave radio systems provide comprehensive transmission of both native TDM and native Ethernet/IP traffic for smooth evolution of transmission networks. They will enable the introduction of next-generation IP-based services during this transition period.

We will explore this category of digital microwave technology for wireless backhaul, which is becoming ever more important as the 4G LTE wireless revolution gets underway with all due earnestness, even while the current 3G—and even 2G—networks continue to carry traffic for the foreseeable future.

Our current white paper builds on Aviat Networks‘ previous April 2010 white paper titled “What is Packet Microwave?” and provides market data from recent industry analyst reports that demonstrate the significant and continuing role of TDM in mobile backhaul networks and some of the prevailing concerns of operators in introducing Ethernet/IP backhaul services.

Mobile Security Requires More Than Secure Wireless Devices

When people think of mobile security, they usually think of encryption for their smartphones, tablet computers such as the BlackBerry PlayBook or other wireless devices. Or they think of a remote “wipe” capability that can render any lost device blank of any data if some unauthorized party did in fact try to enter the device illegally. These wireless solutions are all state-of-the-art thinking in the mobile security community. And many wireless equipment OEMs and third-party mobile security providers offer them.

But they only protect the data on the devices. They only protect so-called “data at rest” once it’s been downloaded onto the iPhone or iPad. They don’t speak to the need to cover “data in motion” as it is transmitted over the air. Some parts of the over the air journey are protected by infrastructure in the form of Wi-Fi and GSM. One is notoriously subject to human failing to enable security and the other has been broken for sometime. And then there is wireless security for backhaul. In this area, there has not even been an industry standard or de facto standard established. And most microwave solutions providers don’t even offer options for wireless security on the backhaul.

Fortunately, this is not the case across the board. Strong Security on the Eclipse Packet Node microwave radio platform offers three-way protection for mobile backhaul security: secure management, payload encryption and integrated RADIUS capability.

Smart Grid is an enabling opportunity for operators to help address energy generation and consumption in an intelligent and efficient manner.

The explanation of Smart Grid solutions in this comparison chart should help to clarify the various choices for wireless connectivity—from access to backhaul, for data or management transmission—using any one or a combination of various technologies.

It compares various wireless technologies for wireless applications related to Smart Grid communications. It also covers general information such as “How to use in Smart Grid,” key advantages and notable weaknesses.

Key technical parameters such as bandwidth, coverage, user data rates and cost are also considered. Microwave, WiMAX, Mesh, LTE, 3G cellular, Power Line Carrier, WLAN and Zigbee are described.

Microwave Wireless Backhaul Case Study: Tooele County (Utah)

In an all-indoor configuration, Aviat Networks’ Eclipse Packet Node platform has delivered flexibility to Tooele County, Utah, to transition its partially mountainous, rural legacy TDM network to IP when the traffic demands it. When greater functionality is required, the modular nature of the platform is called upon to ease installation and maintenance.

“The entire design is highly modular, and we are able to drop in new network cards with the latest technology. We just swap new cards for old,” says Dave Williams, communications manager for Tooele County. “So not only does Eclipse Packet Node provide native TDM support for our latency-sensitive, mission-critical traffic today but also allows us the flexibility to migrate to native all-IP traffic as our applications evolve. With this platform, we get the best of both worlds.”
