New Wi-Fi broadband system
p2pnet.net News:- A new Wi-Fi broadband broadcast technique will give mobile Wi-Fi devices Net access in locations where an online connection is impossible, says its Dutch inventor, Joe Bobier.
Called xMax and owned by XG Technology in the US, it’s a “relatively silent communications method, despite the fact it uses a broadcasting channel that is already crowded with pager or TV signals,” says Softpedia News. “This solution poses no threat of interference with other signals, but allows the breach of other frequencies, in order to obtain an optimum broadcasting channel.”
The system allows signals that would normally be too weak to be received by normal antennas to be broadcast, says the story. With the help of specially-designed receivers, “these signals can be tracked, because they are specially calibrated in order to be detected in certain pre-established conditions.”
xMax is, “trespassing radio frequencies, although trespassing is not the right word, because we’re allowed to transmit a signal if it doesn’t interfere with other, stronger signals,” Reuters quotes Bobier as saying.
It isn’t an efficient way to transport data through the airwaves, Princeton University electrical engineering professor states, “but it is doing it in a benign way. You won’t even know it’s there. It’s very clever.”
xMax could interest telecoms or Net operators with no radio spectrum because they can begin wireless broadband services with, “very few base stations and add more stations and increase density as demand rises,” says Reuters. “It is also appealing for rural areas which operators find too costly to cover with the current third generation mobile phone networks which need base stations every few miles.”
Radio chips for devices should be in the $5-$6 range, “when built in volume while base stations will be around $350,000,” it adds.
