sing Adjacent Phone Antennas Could Improve Data Transfer
Researchers at the University of Bristol's Center for Communications Research are studying multiple-input multiple-output (MIMO) technology, which uses several antennas to transmit and receive data, in order to make mobile phones transfer data faster. The researchers created a virtual MIMO system involving a smartphone, a laptop, and a bicycle-helmet-mounted antenna linked with a short-range wireless connection.
"The concept of virtual MIMO has been around for a little while," says Bristol professor and project leader Mark Beach. "We wanted to understand the impact of different form factors [devices] when you’re moving."
During testing, the researchers found that a virtual MIMO system could boost data transfer rates by 50 percent.
"One of the things we found was that the detuning by somebody holding the device makes quite a significant difference to the operation of a MIMO system," according to Beach. He says that "this would be of benefit to a network operator because you're making the whole communications process much more efficient, using much less channel resource."
