subject: Frbiz.com Reports Bell Labs Demonstrated Lte Rate Used To Improve The New Technology [print this page] Today announced that its Bell Labs research and development institutions and the Deutsche Telekom Laboratories, Fraunhofer Heinrich-Hertz Institute, as well as suppliers Kathrein antennas together to complete the industry's first multi-point collaboration for a new transmission (CoMP) technology, field testing, the technology can enhance the 3G network and the Long Term Evolution (LTE) wireless broadband network in the data transfer rate and ensure stability of service quality and data throughput. Through the coordination and consolidation of multi-antenna signal, multi-point collaborative transmission (CoMP) can ensure that mobile users are in the center of LTE cellular or the edge of the network access or share videos, photos and other high-bandwidth business, are able to enjoy the same performance and quality service.
Collaborative multi-point transmission (CoMP) solution is based on Bell Labs in wireless networks, a leading research and take advantage of Bell Laboratories pioneered Technology Network MIMO (Multiple Input Multiple Output) advantage, the technology can reduce the wireless networks interference, and through close coordination of multi-access point signal transmission and reception to enhance efficiency. The solution reflects the Bell Labs for its consistent commitment to open innovation, and through a clear demonstration of the results showing the significant benefits it contains.
The field test sites located in the center of Germany's capital Berlin, and become by the German Research and Education (BMBF) sponsored by the implementation of the "environmental services and systems Engine" (EASY-C) as part of research projects. The test was carried out in the technology world's first field test. Earlier, the CoMP technology into wireless networks worldwide, has begun to conduct an extensive evaluation, but never carried out field trials.
The mobile device and base station transmission between the tests using the 2.6GHz band, the band is considered the deployment of commercial LTE services in Europe the best band. Signals from mobile devices is set at 500 meters away from the building on the disparity between the two RF units (RRH) to receive, and then forwarded to the Alcatel-Lucent's optical fiber link LTE base station (eNodeB) contains a modem and control components the central unit. Subsequently, the signal will be consolidated so as to enhance signal strength.
