How to get 1 Gigabit per Second Data Rate Over Wireless Internet
A 1 gigabit per second data rate over a wireless Internet can be achieved without increasing
bandwidth. All you need is 9 antennas (8 for data and 1 for control) for transmission and 9 for
reception. This new technology is called Parallel Transmit Parallel Receive (PTPR).
PTPR is analogous to the parallel interface connection on a printer or the IEE 488 interface on
an instrument that is controlled by a computer.
With quadrature amplitude modulation (QAM) or orthogonal frequency division modulation
(OFDM), 8 separate streams of data bits and 1 stream of control bits are broadcast
simultaneously and received on separate sub carriers. The data rate can be increased 256 times
more at a lower radio frequency that doesn't require line-of-site between transmitter and
receiver. This whole process can be controlled by digital signal processing (DSP) chips.
