Understanding AT&T’s Key Network Performance Indicators



AT&T’s network performance

Network performance is a key factor affecting customer retention. AT&T (T) continues to invest in improving its network and is focusing on an SDN (software-defined networking) approach to transforming its network.

SDN helps telecom companies save costs and provide more flexibility, as this approach requires them to virtualize their networks instead of spending on dedicated fixed hardware. AT&T’s penetration in SDN rose to 34% by the end of 2016 and expects to reach 75% by 2020.

In the past, AT&T has spent heavily on its Project Velocity IP, or VIP, a program aimed at upgrading its wireless and wireline broadband infrastructure. AT&T claims that its network now has 70,000 cell sites—much more than any competitor.

Notably, the company has now expanded its LTE (long-term evolution) reach to Mexico, which means that AT&T’s 4G LTE footprint now covers more than 400 million people in North America.
