did u know about xMax?

Question

it is a communication technology

Answer 1

xMax is a wireless networking protocol with broadband speed. xMax can cover a wider area than WiMax and has a signal that's better at penetrating buildings. xMax transmits at powers that are low enough not to interfere with other signals, which means it can use radio channels that are already being used for other purposes.

Answer 2

XMax
From Wikipedia, the free encyclopedia


xMax developed by xG Technology, LLC is a radio frequency (RF) modulation and encoding technology that uses individual or "integer" sinusoidal waves to convey information. While applicable to wired mediums such as copper and coaxial lines, the technology is first being introduced as a wireless communications technology whereby its developers claim that it is capable of extending the range and reducing the transmit power compared to conventional approaches, including cellular technologies and fixed wireless approaches such as WiMAX. The company announced in July 2006 that with regional partners they are building an U.S. wide mobile phone service using xMax handsets with VoIP starting in the second quarter of 2007 (xG Technology announces mobile VoIP program).

“A fundamental paradigm shift in the way radio signals are modulated and demodulated.”

Developed by xG Technology in Florida Rather than transmitting many RF cycles for each bit of data to be sent, xMax does it in a single RF cycle.

Power is saved not only in the transmission, but because receivers will only recognize single-cycle waveforms, power isn't wasted on un-intended RF signals

xG President of Operations Joe Bobier invented xMax and has this to say of his discovery "It just occurred to me that the least amount of radio energy I could have is one photon — one wavelength — and the least amount of data I could have is one bit. It just struck me that there was a correlation there."

Some current specifications

* Antenna: One omnidirectional transmitter located on TV broadcast tower at a height of 850 feet;

* Range: 20 miles, covering the cities of Miami and Fort Lauderdale, including inside buildings (see map).

* Data rate: At least 10 Mb/s throughout the coverage area.

* Spectrum used: A 6 kHz carrier on dedicated spectrum and 10 MHz of information-bearing spread spectrum in the unlicensed 900 MHz band.

* Interference: None, despite the presence of a TV transmitter on the same tower.

* Power: A maximum of 50 W for the carrier and less than 0.15 W for the information-bearing channels.
