Aviat: The American Microwave Company and The Trusted Choice for State-Wide Microwave Networks
Aviat is the #1 provider of microwave and microwave routing systems to state/local government networks nationwide with 25 of 50 state-wide networks running Aviat equipment.
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.
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.

Happy New Year and thank you to the avid readers of the Wireless Transmission Blog! We had readers from 186 countries (out of the official 192) during 2012! You’ll find other interesting statistics in the 2012 annual report WordPress has prepared below.
Here’s an excerpt:
4,329 films were submitted to the 2012 Cannes Film Festival. This blog had 40,000 views in 2012. If each view were a film, this blog would power 9 Film Festivals. Click here to see the complete report.
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.

Alphonso Arnal, senior technology marketing manager for Aviat Networks, talks about interoperability testing. Running the IOT lab, he helps test proofs-of-concept. Testing can be done for SONET or packet-based networks. Aviat Networks wireless solutions and other vendors’ solutions can be tested to show how they will perform in real-life applications.
