Android smartphone owners on T-Mobile USA's network consumed an average of 1.36 GB of data per month in January, up 0.44 GB from 0.92 GB in December, according to new statistics from NPD Connected Intelligence. One reason may be that T-Mobile has been busy refarming its 1900 MHz PCS spectrum for HSPA+ services as it prepares to launch LTE on its 1700 MHz AWS spectrum. This development gives T-Mobile customers more areas in which they can access high-speed data service, which may encourage more consumption. The uptick among T-Mobile's Android users just one key finding from NPD's recent report. FierceWireless teamed with NPD Connected Intelligence to publish the results of the firm's SmartMeter surveying software. NPD's SmartMeter software is installed on around 1,500 smartphones and it allows NPD to track users' cellular data usage. Also, NPD said it "normalized" its previous iPhone figures, which were derived from a smaller base, to bring them in line with the numbers the firm is obtaining from its current, 500-member panel size.
