Capacity is interference-limited in todays networks and interference mitigation plays an important role in network planning. Interference diversity by frequency hopping is one proven technology in FDMA systems. A channel carrying multiplexed packet-data from different users can be expected to show interference diversity when acting as a source of interference. This phenomenon, called location diversity here, is investigated by exam- ining the carrier to interference ratio (CIR) of General Packet Radio Service (GPRS) packet data channels (PD- CHs) in uplink under heavy load conditions in a large multi-cell scenario. It is shown that a CIR gain of 2 - 3 dB for bad receiving conditions is possible with packet- based systems.
