3G Technology is designed for multimedia communication. It provides services like higher data transfer rates. One of its key visions is to provide seamless global roaming, enabling users to move across borders while using the same number and handset. According to ITU it is expected that IMT-2000 will provide higher transmission rates: a minimum speed of 2Mbit/s for stationary or walking users, and 348kbit/s in a moving vehicle.
3G technologies make use of TDMA and CDMA
3G technology is much flexible, because it is able to support the 5 major radio technologies. These radio technologies operate under CDMA, TDMA and FDMA.CDMA holds for IMT-DS (direct spread), IMT-MC (multi carrier). TDMA accounts for IMT-TC (time code), IMT-SC (single carrier). FDMA has only one radio interface known as IMT-FC or frequency code.
GSM technology was able to transfer circuit switched data over the network. The use of 3G technology is also able to transmit packet switch data efficiently at better and increased bandwidth.
Digital enhanced cordless telecommunications (DECT) is another 3G Technology (Thrid Generation Technology). DETC was developed by European telecommunications standards institute; however it is now widely popular in the other countries of the world as well. It runs over a frequency of 1900Mhz. WiMax is a 3G Technology (Thrid Generation Technology) and it is referred to as worldwide interoperability for microwave access. It is a wireless technology. It transmits variety of wireless signals. It can be operated on the multi point and point modes. it is portable technology. This technology is based on the wireless internet access. Name of the WiMax was developed in 2001 by WiMax forum. This technology removes the need for wires and is capable enough to provide 10mbits/sec. it can connect you to hotspot.
