 Nokia Siemens Networks has completed the world’s first multi-user field trial in an urban environment using the new Long Term Evolution (LTE) technology that offers mobile data rates up to 173 Megabits per second.
These days users of mobiles require faster data rates, quicker response times and longer battery life in order to enjoy the benefits of services such as voice over IP, mobile video, sharing and collaboration and rich multimedia telephony.
One year ago Nokia Siemens Networks conducted the world’s first LTE demonstration in conjunction with MIMO (Multiple Input / Multiple Output) antenna technology. In this demonstration peak data rates of 160 Megabits per second were realized.
The now performed field trial was a world first since it was conducted in a real urban outdoor environment with multiple users using the new 2.6 GHz spectrum.
It confirms that LTE performance requirements can be met using 3GPP standardized technologies and it realized data rates of more than 100 Mega bits per second over distances of several hundred meters, while maintaining excellent throughput at the edge of typical urban mobile radio cells.
It also proves that LTE makes optimum use of the OFDM (orthogonal frequency-division multiplexing) and adaptive multi antenna technologies, as well as the intelligent algorithms used to schedule user traffic to the radio resources in multi-user environments.
This enables substantial optimization of network capacity and, in combination with a scalable flat network architecture, this will provide substantial benefits for operators offering mobile broadband connectivity.
This field trial was assisted by the Heinrich Hertz Institut (HHI), a world-wide recognized expert centre in the field of intelligent adaptive MIMO/Algorithms.
To obtain data about LTE performance in an actual urban deployment environment, an LTE base station was installed at a typical base station site: the top of the Heinrich Hertz Institut building in the center of Berlin. Cars with LTE test terminals were driven up to 1km away from the base station to measure the LTE cell’s coverage and throughput.
The base station, supporting LTE with a 2 by 2 MIMO (Multiple Input / Multiple Output) antenna system having 120 degree sectors, has been installed to support continuous testing activities over the next year. It transmits with 20MHz bandwidth in the 2.6GHz band, for which Nokia Siemens Networks has acquired test licenses in major cities throughout Germany. The spectrum in this band will be awarded to mobile operators in the next few years.
LTE availability is planned for a 2010 timeframe.
