Sprint: Core Switch/Regional Data Center

Background

This Kansas City building houses legacy wireline, data, and core wireless network equipment and has evolved from a long distance switch to a Regional Data Center supporting Sprint’s new Network Vision Plan. Through this plan, upgrades to the Holmes Street Switch and other similar sites allow Sprint to decommission many other facilities, and thus reduce Sprint’s overall energy consumption significantly.

Due to the nature of business at Sprint, 87% of electricity consumption by the company derives from the Sprint Network. With a focus on new technologies, Sprint developed the Network Vision Plan which increases efficiency at select sites while enabling decommissioning of 30,000 cell sites and 48 wireless switch facilities across the country. Network Vision will continue to enable energy efficiencies through IP based networking and service “layering” using the Network’s 800, 1900, and 2500 MHz spectrum while supporting future wireless technology advances. The Network Vision program has reduced network energy intensity more than fivefold to 0.45 MWh per Terabit by year end 2013.
