Hello, and welcome to another edition of Telecom Engine’s Audiocast series. I am Sean Buckley, editor in chief of Telecom Engine. Today, I am happy to be joined by Stuart Little, marketing director for Harris Stratex Networks. Stuart is going to talk to us today about leveraging microwave technology for wireless backhaul.

Little answers the following questions in this Audiocast:

• When it comes to wireless backhaul, the two dominant methods have been either E1/T1 or TDM-based microwave solutions, but now we’re hearing more about carriers adopting or considering using IP/Ethernet for wireless backhaul. What’s driving the migration from TDM to IP/Ethernet for wireless backhaul and how does Harris Stratex approach this opportunity?

• While microwave links were traditionally TDM-based, the industry is clearly offering and has made the transition to more IP/Ethernet based approaches. Can you talk about this transition and Harris Stratex’s approach?

• To help ease the migration pain for a wireless operator using Ethernet for backhaul, there’s been talk about IP/Ethernet architecture for backhaul where you maintain TDM for voice and then Ethernet for data. Are you seeing a similar trend?

• During the CTIA show, one issue raised during a panel session on wireless backhaul is that wireless operators could potentially leverage a hybrid backhaul approach that incorporates both available fiber and microwave. What’s your take on that kind of network solution?

• One issue that’s gaining momentum is dealing with clock synchronization when using Ethernet for wireless backhaul. How is Harris Stratex addressing that issue?

The M2M Switch - turning the wireless business model upside down -- September 1, 2010
While global telecom operators, systems integrators, and enterprises wrestle with Machine-to-Machine, they may struggle to contain a tide that has only just begun to rise. The power of supply chain automation, ubiquitous connectivity, and pervasive computing are so strong, we may already have traversed a threshold into a radically new paradigm in the communications industry, one in which waves of innovation, new economies of scale, and sheer business logic will prevail. While no crystal ball can show us the future of network evolution, we can revisit milestones of technological progress and shed light on the path ahead.
