Wireless network smashes world speed record

A new world record has been set for transmitting data across a wireless network, claim researchers in Germany.

A team at Siemens Communications research laboratory in Munich, have transmitted one gigabit (one billion bits) of data per second across their mobile network. By contrast, the average wireless computer network can send only around 50 megabits (50 million bits) of data per second.

The researchers used three transmitting and four receiving antennas and a technique for boosting the amount of data that can be sent wirelessly, called Orthogonal Frequency-Division Multiplexing (OFDM), to set their record.

"With our experimental system, we've been able to demonstrate how powerful [multiple] antennas can be in combination with OFDM," says Christoph Caselitz, president of the Mobile Networks Division at Siemens Communications. Caselitz estimates that wireless networks will be expected to cope with 10 times as much data by 2015.
