When the wireless network was all about voice, simple E1/T1 circuits were sufficient, but the rise in all-you-can-eat voice minute plans and new data-driven devices like the iPhone are all putting new demands on a network that was basically designed for one thing: to talk. As a result, wireless operators are having to rethink how they deploy their wireless backhaul network infrastructure. Amir Zoufonoun, Chief Executive Officer and founder of Exalt Communications talks about how operators can address working with today's TDM reality despite the wireless IP future.


In this Audiocast, Zoufonoun addresses the following questions:

• When it comes to wireless backhaul, the two dominant forms have been either E1/T1 and TDM-based microwave solutions. Now, a recent report from Infonetics says that Ethernet/IP-based microwave backhaul is forecasted to be a US$1.8 billion market by 2010. What is driving this trend?

• While we all want to be all-IP, all of the time even with wireless, in the real world, there's going to be (for quite a long time) a mix of TDM and IP. To address that need, Exalt has a vision of carrying IP and TDM in its native form. Talk about your approach and why you chose to go that route?

• What are the measurable benefits to the deployment of Ethernet solutions for backhaul applications?

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