Sprint’s legacy network may not be the fastest, but the carrier is taking steps to improve it. Today, the Now Network announced it has begun rolling out Spark, the carrier’s tri-band 4G LTE designed to improve speeds in congested markets, to customers in Philadelphia and Baltimore. Sprint also said that the network upgrade will include HD Voice, a much-improved voice codec that increases the call quality.
The rollout brings the total number of Spark locations to 14. That’s only a fraction of Sprint’s LTE network, though. We can only hope that the carrier’s recent losses and Softbank backing will help to motivate deployment in the near future.
In order to use Spark, you’ll need a compatible handset. Only the Galaxy Mega, Galaxy S4 mini, LG G2, and HTC One Max can take advantage at the moment, but Sprint promises future smartphones will incorporate tri-band radios.
