AT&T has expanded the use of carrier aggregation to its LTE network in New York City, San Francisco, and Dallas.
Tom Keathley, AT&T’s SVP of network and product planning, told Fierce Wireless that AT&T has deployed carrier aggregation “in a significant way.”
The company plans to further expand carrier aggregation across its network over the course of the year. Carrier aggregation allows two separate spectrum bands to act as one, which improves data speeds and throughput. Keathley also noted that about 20 of AT&T’s handsets support LTE Advanced (Cat 4), which allows them to make use of carrier aggregation.
