. According to CSR, EGPS delivers a "universal positioning capability that will not only work reliably indoors and in zero GPS signal conditions, but greatly speed time to fix in poor GPS reception areas where most handsets are used." More specifically, it can "exploit data available from the cellular network to speed GPS fixes and provide complementary, fast, and reliable location sensing when GPS signals are weak or unavailable." CSR is hoping to add eGPS capabilities to handsets for less than $1 per unit. E-GPS combines CSR's "Matrix" technology with GPS – when a user initiates a location request they get a Matrix location instantly using cell tower information, accurate to within 100m. Then CSR's "Fine Time Aiding" helps the device know where to look for a GPS signal, to quickly acquire satellite information within seconds. Fine Time Aiding enables a more aggressive search and is claimed to be equivalent to 6 dB more sensitivity than can be achieved by any GPS hardware correlator in the terminal. CSR claim that this enables software-only GPS solutions to operate reliably in all environments, and that eGPS is superior to
