Why AT&T Is Counting on Network Virtualization

AT&T’s network performance

The network performance of a telecommunication company plays a vital role in customer retention. AT&T’s (T) postpaid phone churn rate improved year-over-year (or YoY) to 0.84% in 3Q17 from 0.90% in 3Q16.

This is beneficial for AT&T primarily because its smaller competitors Sprint (S) and T-Mobile (TMUS) have worked to attract users from AT&T and Verizon (VZ).

Why AT&T Is Counting on Network Virtualization

AT&T has spent approximately $14.0 billion on Project Velocity IP (or VIP), a program directed at enhancing its wireless and wireline broadband infrastructure. Also, the telecom company is concentrating on SDN (software-defined networking) and NFV (network function virtualization) technologies to enhance its network.

Currently, AT&T can virtualize about 45% of its network functions with a goal of reaching 55% by the end of 2017. Its long-term goal is ~75% by the end of 2020.
