AT&T Mobility (NYSE:T) said it will add HSUPA capabilities to its Motorola Mobility (NYSE:MMI) Atrix 4G and HTC Inspire 4G smartphones sometime next month.
The carrier confirmed to CNet that it will add support for HSUPA, which can deliver uplink speeds of as much as 5.76 Mbps, via a software update at some point in April, though it declined to give a specific date. AT&T had confirmed earlier this month, via responses to inquiries to the Better Business Bureau, that it was not capping uplink speeds on the phones, but that it had simply not turned the functionality on.
An AT&T representative wasn't immediately available to comment on the reason AT&T withheld HSUPA functionality in the first place.
AT&T also noted that its other recently announced HSPA+ smartphone, the Samsung Infuse 4G, will ship with its HSUPA radio turned on.
All of the phones are part of a batch of HSPA+ smartphones the carrier is deploying to take advantage of its HSPA+ network and enhanced backhaul speeds ahead of its launch of LTE later this year. AT&T expects to cover the majority of its network with HSPA+ and upgraded backhaul connections by year-end.
