AT&T has improved its LTE network in Chicago and several other markets by using an LTE-Advanced technique called Carrier Aggregation. GigaOm confirmed the soft launch with AT&T SVP of Network Technologies Kris Rinne. With Carrier Aggregation, AT&T has combined the channels of its existing spectrum to double the capacity. AT&T is running LTE in both the 700MHz and AWS bands in Chicago. By aggregating the channels together, AT&T can deliver theoretical peak download speeds of 110Mbps to devices with the proper radio support. At the moment, AT&T is selling only one device with Carrier Aggregation, the Unite mobile hotspot. The Samsung Galaxy S5 is expected to be the first smartphone to support Carrier Aggregation in the U.S. AT&T did not name the other two markets that have access to Carrier Aggregation, but said that more markets on are on the way. Sprint, T-Mobile, and Verizon Wireless are all in various stages of deploying Carrier Aggregation in their own LTE networks.
