HSPA News
HSPA (High Speed Packet Access) is a two way, up and down, cellular data link for handsets using WCDMA, the 3G standard from 3GPP. HSPA is now used in around 100 countries and almost 300 operators. In short it’s how you get the internet over a cellular signal. The uplink is HSUPA, the downlink HSDPA. It supports data rates up to 14 Mbps from base station to phone and 5.8 Mbps the other way, achieved simply with a software upgrade on 3G. HSPA is a shared 5 MHz data channel, separated from the cellular voice signals, with clever software to optimize performance – it selects which order to serve data in because handsets closer to a base station can get data faster, using a dense modulation, so HSPA prioritizes data requests based how far away each phone is. HSPA can be improved to HSPA+ or Evolved HSPA by adding more antennas in the phone or taking signals from two base stations, and this will eventually get networks up to 84Mbpsafter which HSPA will be replaced by LTE, which treats everything as data, even voice.
