AT&T squeaks past T-Mobile in network latency measurements

AT&T Mobility (NYSE: T) managed to narrowly beat T-Mobile US (NYSE:TMUS) with the nation's shortest LTE network latency times, according to new findings from OpenSignal. The results are notable considering T-Mobile previously enjoyed the lowest latency recordings.

Network monitoring firm OpenSignal uses a panel of more than 1 million consumer devices to provide real-world data on the performance and coverage of mobile networks. Due to a partnership between OpenSignal and FierceWireless, we're able to publish the company's network latency results for the nation's top four nationwide wireless carriers. In the months of April and May, AT&T posted the lowest--meaning, the fastest--network latency speeds of all the nation's Tier 1 carriers. T-Mobile came in a close second, followed by Verizon Wireless (NYSE: VZ) and, in last place, Sprint (NYSE: S).

Latency is defined as the time it takes for a source to send a packet of data to a receiver. Latency is typically measured in milliseconds. The lower the latency (the fewer the milliseconds), the better the network performance.
