US scientists believe they have developed a two-way wireless technique which could potentially boost Wi-Fi broadband speeds.
Researchers at Stanford University, California, said the prototype solution allows radio signals to be sent and received at the same time on a single channel.
At present, signals are only able to travel in a single direction at any one time, reducing the speed at which communications can be exchanged.
The university said the technique could potentially double the speed of wireless signals, which could provide a significant boost for Wi-Fi broadband users in the future.
Philip Levis, Assistant Professor of Computer Science and of Electrical Engineering at Stanford, said conventional textbook knowledge suggested that the technique was impossible.
"The new system completely reworks our assumptions about how wireless networks can be designed," he said.
Last month, UK broadband provider Sky revealed it had purchased Wi-Fi network operator The Cloud in a bid to establish a presence in the public wireless broadband market.
