What is 802.11n?
802.11n is a newer standard WiFi LAN or wireless network technology of the local area, which is subsequently according to standards 802.11a, 802.11b and 802.11g. Its own name is IEEE 802.11n, because it is a protocol developed by the international non -profit institute of electrical engineering and technicians . The "11" number refers to the IEEE working group assigned to the standards of 802 and "N" refers to a special group of tasks in this body known as tgn .
IEEE 802.11N Standard is scheduled to review TGN in November 2005 in November 2005 and debut on the market. Reportedly, it will offer four times data transfer speeds in the current Fastest WiFi technology. It will also work on the 2.4 Gigahertz (GHz) band, such as 802.11b and 802.11g. This frequency does not require the availability of line-ups, such as 802.11a, which works in a regulated 5 GHz band.
If you want to get a real idea of speeds expected with megabits per second (MBPS), see Below table that compares different StandaRDY 802.11:
IEEE expects a smooth transition to 802.11n with backward compatibility built into new equipment, allowing consumers and businesses to gradually upgrade network equipment. Faster speeds allow for more robust applications to effectively perform public hotspots and private ropes, and a larger range is also reflected.
As well as the previous advanced WiFi standards, 802.11n will use more receivers and transmitters, technology known as outside (multiple input output). This allows parallel currents of data transfer or spatial multiplexing . Standard 802.11n will also include the multiplexing ofDM or the orthogonal frequency of the division. The OFDM divides the frequency of the signal into several modulated channels for increased permeability. In addition to private and commercial ropes, 802.11n is expected to support a number of personal electronics, including pocket devices.
