A team at the Siemens Communications research laboratory in Munich have transmitted one gigabit of data per second across their mobile network.

The researchers used multiple receiving antennas and Orthogonal Frequency-Division Multiplexing (OFDM) to set their record.

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.

OFDM splits carrier signals into smaller sub-units that are synchronized to reduce interference. The Siemens team also developed new computer algorithms to send more data using existing hardware.
