So far, 32 markets currently receive Sprint's 4G LTE signal and the carrier noted that during the pre-launch phase, some Sprint subscribers in areas where LTE is coming soon, might start to receive a 4G signal on their device. Once the LTE signal in a city is officially launched, the carrier adds enhancements to improve the signal. Sprint says that eventually its LTE footprint will match its 3G coverage.
Speaking of 3G, Sprint is enhancing its 3G capabilities in some major markets to give customers an improved wireless signal, improved in-building performance and fewer dropped calls. Those areas receiving improvements to 3G signals include Baltimore, Boston, Chicago, Los Angeles, New York and Washington, D.C.
