Sprint today indicated that it has rearranged the executives who manage its network business. Both Steve Elfman, president of network operations, and Bob Azzi, senior vice president of networks, will leave the company. The changes are effective immediately, according to Sprint spokesperson Kelly Schlageter, who confirmed the shakeup to Fierce Wireless. Azzi is retiring effective March 14, while no date was given for Elfman's departure. In their place, Sprint has promoted John Saw, formerly the company's senior vice president of technical architecture, to the position of Chief Network Officer. Before joining Sprint, Saw was CTO at Clearwire, which Sprint acquired last year. Sprint is in the middle of deploying its LTE network across the U.S., including Sprint Spark, which depends on tri-band LTE coverage to improve speeds and service. Sprint has been slow to get its LTE network up and running, and blamed the delay on its network equipment providers.
