Nokia Simens Test made 4G Mobile Broadband Technology closer to Reality
Long Term Evolution (LTE), Nokia Siemens Networks’ tests, announced last week, is a potential successor to 3G. The test offers theoretical data rates of up to 173 megabits per second. Currently, Mobile WiMax is the leading competitor in this arena that offers data rate upto 70 mbps. The fastest currently available mobile broadband, HSDPA, offers around 7.2Mbps.
Both LTE and mobile WiMax use the OFDM modulation scheme and multiple-input multiple-output (Mimo) technology, which is based on the use of multiple antennae. Nokia Siemens Networks announced that it had completed the world’s first multiuser field trial of LTE in an urban environment. The trial that took place in Berlin utilized 20MHz of bandwidth in the 2.6GHz spectrum.
The company statement read:
The trial confirmed that LTE performance requirements can be met using 3GPP standardized technologies and it realized data rates of more than 100Mbps over distances of several hundred meters, while maintaining excellent throughput at the edge of typical urban mobile radio cells.
I can tell for sure that the next generation mobile broadband technologies will revolutionise the wireless industry.
