AT&T to begin trials of DirecTV Now in Austin using a fixed 5G connection
In the lab, AT&T says that it has been able to achieve speeds of 14Gbps using a wireless connection. Additionally, it has been able to produce a latency of less than 3 milliseconds. This measures the time it takes between pressing a button and seeing the results of that action start to appear on the screen. For 5G, the industry expects latency to be less than 5 milliseconds.
AT&T continues to advance its 4G service. Some of its current cell sites are hitting peak theoretical speeds of 1Gbps. The carrier currently uses three carrier aggregation, which widens the network pipeline to allow data speeds to increase. It hopes to eventually employ four carrier aggregation. AT&T also enlists mmwave technology which can help the carrier produce multi-gigibit speeds.
During the second half of this year, AT&T will work with Qualcomm and Ericsson on trials based on what AT&T believes will be the 5G New Radio specification that the industry is building. The faster that the industry agrees to standards for 5G, the quicker testing can be done and certified.
