Wireless broadband

[1] Originally the word "broadband" had a technical meaning, but became a marketing term for any kind of relatively high-speed computer network or Internet access technology.

[4] Many fixed wireless networks are exclusively half-duplex (HDX), however, some licensed and unlicensed systems can also operate at full-duplex (FDX)[5] allowing communication in both directions simultaneously.

Outdoor fixed wireless broadband networks commonly use a priority TDMA based protocol[6][7][8][9] in order to divide communication into timeslots.

This timeslot technique eliminates many of the issues common to 802.11 Wi-Fi protocol in outdoor networks such as the hidden node problem.

In 2005 the Federal Communications Commission adopted a Report and Order that revised the FCC's rules to open the 3650 MHz band for terrestrial wireless broadband operations.

[11] Another system that is popular with cable internet service providers uses point-to-multipoint wireless links that extend the existing wired network using a transparent radio connection.

[12] On November 14, 2007, the Commission released Public Notice DA 07–4605 in which the Wireless Telecommunications Bureau announced the start date for licensing and registration process for the 3650–3700 MHz band.

[16] These early WISPs would employ a high-capacity T-carrier, such as a T1 or DS3 connection, and then broadcast the signal from a high elevation, such as at the top of a water tower.

To receive this type of Internet connection, consumers mount a small dish to the roof of their home or office and point it to the transmitter.

Also, companies looking for full diversity between carriers for critical uptime requirements may seek wireless alternatives to local options.
