Gigabit Wireless

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.[1][2]

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).

Examples of frequency and bandwidths at and approaching Gigabit Wireless
Category Frequency Band size (MHz) Modulations Full Duplex capacity (Mbit/s) Distance References
Indoor Consumer Grade AC 5 GHz 80 IEEE 802.11ac ~200 Same room [3]
Outdoor PtP AC 5 GHz 80 IEEE 802.11ac 290 20 km [4]
Unlicensed carrier grade 24 GHz 100 256 QAM 1000 15 km [5]
Licensed modern carrier grade 11 GHz 100 256 QAM 750 100 km [6]
Carrier grade V-Band 60 GHz 125-500 64 QAM 500 - 1000 1 km - 2 km [7][8]
Carrier grade E-Band 80 GHz 125-1250 32 QAM 1000 - 5000 10 km [9][10]

Note: the higher bandwidth devices require a less complex modulation to achieve high speeds.
