HSPA (High Speed Packet Access): A family of high-speed 3G digital data services available to GSM carriers worldwide. The service works with HSPA cellphones as well as laptops and portable devices with HSPA modems. Although based on WCDMA, HSPA is a major enhancement with more channels and different modulation and coding techniques. In addition, HSPA can recover faster from errors than WCDMA. HSPA was deployed in 2005, starting with HSDPA in the U.S.
