A short backfire antenna (or short back-fire, SBA, SBF or SBFA) is a type of a directional antenna, characterized by high gain, relatively small size, and narrow band. It has a shape of a disc with a straight edge, with a vertical pillar with a dipole acting as the driven element in roughly the middle and a conductive disc at the top acting as ...
In addition, certain improved WokFi antennas, and antennas made using 60 to 90 cm (2-3 ft) diameter round or oval satellite TV dishes, allow even far greater range, up to 20 km (12 miles). [ 4 ] Interference from nearby 2.4 GHz signals (perhaps from cordless phones, AV links, leaky microwave ovens, other APs or Bluetooth) can be nulled out—a ...
Long-range Wi-Fi especially in the 2.4 GHz band (as the shorter-range higher-bit-rate 5.8 GHz bands become popular alternatives to wired LAN connections) have proliferated with specialist devices. While Wi-Fi hotspots are ubiquitous in urban areas, some rural areas use more powerful longer-range transceivers as alternatives to cell ( GSM , CDMA ...
Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. To reduce interference with other protocols that use the 2.45 GHz band, the Bluetooth protocol divides the band into 80 channels (numbered from 0 to 79, each 1 MHz wide) and changes channels up to 1600 times per second.

IEEE 802.11n is an amendment to IEEE 802.11-2007 as amended by IEEE 802.11k-2008, IEEE 802.11r-2008, IEEE 802.11y-2008, and IEEE 802.11w-2009, and builds on previous 802.11 standards by adding a multiple-input multiple-output (MIMO) system and 40 MHz channels to the PHY (physical layer) and frame aggregation to the MAC layer.
^A In the 2.4 GHz bands bonded 40 MHz channels are uniquely named by the primary and secondary 20 MHz channels, e.g. 9+13. In the 5 GHz bands they are denoted by the center of the wider band and the primary 20 MHz channel e.g. 42[40] ^B In the US, 802.11 operation on channels 12 and 13 is allowed under low power conditions.
A planar inverted-F antenna (PIFA) is used for wireless circuitry implemented in microstrip.The microstrip format is the format of choice for modern RF electronics. It can be used to implement required distributed-element RF components such as filters, while at the same time being economical because the same mass production methods are used as for printed circuit boards.
