AT&T to roll out HSUPA (USA)AT&T says it plans to upgrade its 3.5G mobile network with high speed uplink packet access (HSUPA) technology in October and November. The upgrade will allow the largest US cellular operator to offer high speed data services with average data upload rates of between 500kbps and 800kbps, up from around 100kbps-150kbps currently. The operator says the growing popularity of social networking sites and personal blogs is creating greater demand for faster upload speeds. AT&T launched its first 3.5G networks in December 2005.
