In a bid to achieve a downlink transmission rate of 300Mbps over a high-speed wireless network, NTT DoCoMo (
News -
Alert), Inc. has began testing an experimental Super 3G
system for mobile communications.
Super 3G features low-latency data transmission and improved spectrum efficiency. It is a highly advanced version of High-Speed Downlink Packet Access (HSDPA
) and High-Speed Uplink Packet Access (HSUPA), which have been evolved from W-CDMA packet transmission technologies standardized by the 3rd Generation Partnership Project (3GPP).
The 3GPP, a telecommunications standards organization, is currently discussing standardization of Super 3G under the name Long Term Evolution (LTE).
DoCoMo will start with an indoor experiment to test transmission speed using one transmitting and one receiving antenna. The company will then expand the experiment to examine downlink transmission by employing up to four Multiple-Input Multiple-Output (MIMO
) antennas for both the base station (transmission side) and mobile station (receiving side); the goal is to achieve a downlink transmission speed of 300Mbps.
MIMO is an antenna technology for wireless communications in which different data streams are spatially multiplexed using multiple antennas for both transmission and reception on the same frequency
.
DoCoMo will also examine the functionality of applications for voice and image transmission, games and the like and the key capabilities impacting the Super 3G system's marketability.
DoCoMo claims that Super 3G will allow the company to make a smooth transition to 4G in the future.
In July 2006, DoCoMo started accepting proposals from suppliers seeking to develop Super 3G equipment and expects to complete development of Super 3G technology by 2009.
