NTT DoCoMo looks for a revolutionary breakthrough in mobile data transfer speeds. The Japanese company has started testing an experimental Super 3G system for mobile communications.
NTT DoCoMo aims for high results with this experiment. In the future, they will do their best in
managing to reach performances of up to 300 Mbps over a high-speed wireless network. If they succeed, it could mean a revolution for the telecom data transfer and also one step closer to reaching 4G performances.
The super 3G is an advanced version of the High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA). Such technologies developed from W-CDMA packet transmission and each represent one step further in the evolution of data transfer over mobile networks.
NTT DoCoMo's experiment will be made of two parts. In the first one, a
transmission will be tested between two antennas. Later on, they will try to engage up to four Multiple-Input Multiple-Output (MIMO) antennas for both the base transmission station and mobile receiving one. Another aspect which they plan on examining is that of the "handover function", which makes switching the connection between two base stations possible.
The fact that Super 3G is only one step too far from the road that leads to 4G makes it even more important. Actually, this technology is situated just at the borderline before 4G. Because of this, it is highly possible that soon after this
technology is fully accomplished for proper use, a small step will be made towards the 4G one.
NTT DoCoMo expects to be able to bring out for the public to enjoy a final version of the Super 3G technology sometime by the year 2009. Until then, they will continue researching for best solutions and developing the proper equipment for fully introducing it.
