115. Network investment remains a centerpiece of service providers’ efforts to improve their

customers’ mobile wireless service experience. Over the past several years, service providers have upgraded and expanded their networks with technologies that enable faster data transfer speeds, and all of the major mobile wireless providers have now deployed LTE to a significant extent. The following section includes a discussion of the deployment strategies and mobile network upgrades for each of the top five service providers.
