Tom Keathley, Senior Vice President of Network & Product Planning, AT&T

AT&T (NYSE:T) has expanded its use of carrier aggregation to include major markets such as New York, San Francisco and Dallas. In an interview with FierceWireless, Tom Keathley, AT&T's senior vice president of network and product planning, said that the company has deployed carrier aggregation "in a significant way" and will continue to do so throughout the year. In addition, Keathley said that the company now has about 20 LTE Advanced capable devices in its portfolio.

Keathley also discussed 5G, which he said he believes will not include a new air interface technology but will instead use LTE Advanced along with things like Wi-Fi and a low-powered network and possibly a millimeter-wave network. For more see this Hot Seat.
