On Wednesday, AT&T announced its plans to introduce the High Speed Uplink Packet Access (HSUPA) in six new US markets. The deadline for completing the HSPA deployment is the end of June.

Once everything is taken care of, uplink speeds will vary between 500 and 800Kbps; AT&T’s current downlink is of 1.4Mbps. Obviously enough, these are not the speeds the average customer will enjoy on a daily basis; they may be slower or way slower, depending on location, but they would still be very good.

AT&T’s grand plan to broaden its third-generation wireless broadband footprint was announced in February. The company announced deployment of third-generation (3G) wireless broadband service to over 80 additional cities in the US by the end of the current year. Through the initiative, AT&T aims to be able to deliver its 3G services to almost 350 of the leading US markets by the end of 2008, including the top 100 US cities, while it will bring more than 1.500 additional cell sites throughout the United States.

The deployment of HSUPA will help AT&T to complete the transition of the AT&T 3G network to High Speed Packet Access (HSPA) standards, which will make it the first wireless provider in the US to fully have the latest generation of wireless broadband capabilities, being able to align to the continuously evolving needs of customers.
