Colossal provides high-end embedded technology solutions for mobile phones. The services provided include wide-area wireless voice telephony, and broadband wireless data, all in a mobile environment.

The most significant feature offered by third generation (3G) mobile technologies is the capacity to support greater numbers of voice and data customers — especially in urban centers — as well as higher data rates at lower incremental cost than 2G. 3G uses 5 MHz channel carrier width to deliver significantly higher data rates and increased capacity compared with 2G networks.

The first new technology when going from GSM towards UMTS or EDGE is General Packet Radio Service (GPRS). It is the trigger to 3G services. The main point is that the network connection is always on, so the subscriber is online all the time. From the operator's point of view, it is important that GPRS investments are re-used when going to UMTS or EDGE.
