Gigabit Wireless is the name given to wireless communication systems whose data transfer speeds exceed reach or exceed one gigabit (one billion bits) per second. Such speeds are achieved with complex modulations of the signal, such as quadrature amplitude modulation (QAM) or signals spanning many frequencies. When a signal spans many frequencies, physicists refer that a wide bandwidth signal. In the communication industry, many Wireless Internet service providers and cell phone companies deploy wireless radio frequency antennas to backhaul core networks, connect businesses, and even individual residential homes.
Common frequencies and bands for Gigabit Wireless
For more detail on indoor protocols and information, see the see Wireless Gigabit Alliance page. In general, indoor protocols follow a cross-vendor standard and communicate in the unlicensed 2.4 GHz, 5 GHz, and (soon) 60 GHz bands.
The outdoor carrier link protocols vary widely and are not compatible across vendors (and often models from the same vendor).
Note: the higher bandwidth devices require a less complex modulation to achieve high speeds.
