Cellphones capable of transmitting data at a gigabit per second have been demonstrated by NTT DoCoMo in Japan.

In experiments, prototype phones were used to view 32 high definition video streams, while travelling in an automobile at 20 kilometers per hour.

Multiple-input-multiple-output (MIMO) multiplexing was also used to send data via various routes across a network to further increase data capacity.
