Eile kinnitati viimaks IEEE (Institute of Electrical and Electronics Engineers) poolt 802.11n WiFi standard. Kuni 7 aastat arenduses olnuna läbis standard umbes tosina jagu kavandiversioone (draft). Wi-Fi Alliance sõnul ühtivad enamik Draft 2.0 seadmeid uue kinnitatud standardiga.

Väike ülevaade Wifi standartitest kui kedagi peaks huvitama:

Spoiler

802.11a
The 802.11a standard operates in 5 GHz band with a maximum raw data rate of 54 Mbit/s. The range of 802.11a wireless networking equipment is slightly less than that of 802.11b/g because the signals are easily absorbed by walls and other solid objects.



802.11b
The 802.11b standard operates in the 2.4 GHz band and has a maximum raw data rate of 11 Mbit/s. 802.11b devices suffer interference from other products (such as microwave ovens, Bluetooth devices and cordless telephones) that also operate in the 2.4 GHz band.



802.11g
The 802.11g standard operates in the 2.4 GHz band, like 802.11b, but operates at a maximum raw data rate of 54 Mbit/s. Devices based on the 802.11g standard are fully backward compatible with 802.11b hardware.



802.11n
This a proposed amendment to the 802.11 standard and has not yet been fully approved. However, some manufacturers have already begun to distribute 802.11n network equipment. 802.11n devices will include MIMO technology that may offer a raw data rate of up to 248Mbits/s.
