AT&T has a commanding share of the global HSPA market at 21%

Data consumption among mobile devices have skyrocketed as more advanced smartphones hit the market. Some users are getting their first taste of 3G while some are content with the speed, but AT&T looks to continue to be a leader in meeting the demand for data services. AT&T announced last week that it has deployed HSPA in 850 MHz spectrum in Houston, New York City, and Atlanta – the deployment aims to increase bandwidth and capacity in-building coverage. In addition to those major cities, the number two wireless carrier in the country is steadily trying to get its HSPA 7.2 in six cities by the end of the year and 25 of the top 30 markets by the end of 2010. With all these plans in place, AT&T is placing itself in a good spot for meeting up with the demand. According to the GSM Association, AT&T has 21 percent of the global HSPA subscriber base. Although speeds will potentially become faster in certain locations, there is still a need for compatible devices – it's planned for six HSPA 7.2-compatible devices to be offered by the year-end. So as consumers continue to uncover the power of their devices, there will always be a need to increase bandwidth to keep up with demand.
