Building a Wireless Infrastructure: The Critical Role of Backhaul
Out of the limelight of the intense wireless debates over Wi-Fi and cellular access technologies is the often overlooked topic of how to build the wireless infrastructure. According to Cisco Systems, in 2008 about 1.3 exabytes of data were transferred among wireless mobile devices. Furthermore, Cisco estimates that by the end of 2013 1.6 exabytes of mobile data will be transferred per month. And yet, we hardly ever hear anyone in the industry talking about how all this data makes it from the local access point back to the Internet. Somehow, it just happens and we wish it would happen faster!
