How AT&T Is Boosting Its Network Performance

WRITTEN BY Ambrish Shah

AT&T’s network performance

Network performance is a key factor that affects customer retention. AT&T’s (T) network reach and capabilities are unmatched and could be difficult to replicate. AT&T is focusing on an SDN (software-defined networking) approach to transforming its network. SDN helps telecom companies save on costs and provide flexibility, as it requires them to virtualize their networks instead of spending on dedicated fixed hardware.

AT&T expects SDN penetration to rise to 30% by the end of 2016 and to 75% by 2020. AT&T claims that its network now has 70,000 cell sites—much more than any of its competitors. The company has now expanded its LTE (long-term evolution) reach to Mexico, which means its 4G (fourth-generation) LTE footprint now covers 380 million people in North America.
