For the last couple of years we all have been hearing lots about mid-band Ethernet (2 Mbps up to possibly 24 Mbps, with the arguable sweet spot between 2 and 6 Mbps). Suppliers have made special note of the cellular network backhaul opportunity and that frankly has puzzled me a bit, since that particular market segment isn't bigger than the broader metro Ethernet market including enterprises, small and mid-sized businesses and organizations. But Hatteras Network VP Gary Bolton has an answer for that.
The backhaul segment isn't bigger than the others, but it is more urgent for mobile providers as well as the transport providers who provide service with service level agreements, Bolton says. On the mobile side, 3G networks immediately create new bandwidth needs that T1 links aren't well equipped to handle. That's pretty immediate.
Then there are the service providers who sell mobile tower sites connectivity services. And there's urgency there as well. If a circuit goes down, all the timing information at the affected tower can be lost, and then there is the resync time. Mobile carriers hate that.
That typically results in a financial penalty on the transport provider. So the tower backhaul opportunity gets so much attention because both mobile and wireline network providers need a solution right now.
