Sprint has separate equipment for its 800 megahertz and 1.9 gigahertz bands, and for the 2.5 gigahertz band it uses through its relationship with Clearwire Corp. for fourth-generation service. The upgrades will allow the carrier to use all three technologies and others on a single band. The improvements open the possibility for Sprint to incorporate a competing fourth-generation technology, known as Long-Term Evolution, that both AT&T Inc. and Verizon Wireless will use.

Sprint will spend as much as $5 billion to upgrade its network in the next three to five years.
One new base station will handle different frequency spectrums or add different technologies to take full advantage of the spectrum we currently have, the spectrum that Clearwire operates and anything else that we may get over the next 10 years.
