What is wcdma technology

Read more about Mobile Phone History. It employs a 5 MHz channel bandwidth. Using this bandwidth it has the capacity to carry over simultaneous voice calls, or it is able to carry data at speeds up to 2 Mbps in its original format.

However with the later enhancements of HSDPA and HSUPA described in other articles accessible from the cellular telecommunications menu page included in later releases of the standard the data transmission speeds have been increased to In this way the investment required is kept to a minimum. The first modes to be employed are FDD modes where the uplink and downlink are on different frequencies. The spacing between them is MHz for Band 1 networks being currently used and rolled out.

However the TDD mode where the uplink and downlink are split in time with the base stations and then the mobiles transmitting alternately on the same frequency is particularly suited to a variety of applications.

This avoids the transmitter receiving signals which are excessively strong or weak, which could limit the transmitter's efficiency.

This makes it particularly suitable for densely populated areas such as some major Asian cities. The system is also well suited to the technical requirements presented by video calls. The main disadvantages of WCDMA are that it is not used throughout the entire world, which limits take-up of compatible handsets among people who travel internationally, and that it is a relatively complex system which can be expensive to introduce into a new market.
