AT&T to include WiFi in small cell deployments

AT&T plans to include WiFi technology in its small cell deployments (primarily for offloading). Last year, AT&T announced it would install more than 40,000 small cells and 1,000 distributed antenna systems (DAS) across the US. The reason: increased demand for bandwidth from small devices. What I find interesting are AT&T’s efforts to make roaming between Wi-Fi and 3G/LTE networks more seamless. Of course, when you increase the density of wireless access points (whether they consist of small cells or WiFi APs), you get more interference. Moreover you have to bring more Ethernet backhaul to these locations. It’s all very costly and time-consuming and carriers seem to be running behind customer demand no matter what technology they’re using.
