| The 802.11b standard has already gained a good deal of ground in the enterprise environment, in public locations such as airports, coffee shops, business centers and hotels, and increasingly in the home.
Later the evolution towards the 802.11g opened the doors to application requiring higher performances, guarantying 802.11b back compatibility at the same time.
Unfortunately 802.11b and 802.11g operate in a crowded band and this impact on Multimedia Applications which, requiring QoS (Quality of Service), suffer in such environment.
That's move the attention to the 802.11a.
802.11a supports the same 802.11g data rates and it enables multimedia applications for WLAN operating in an uncrowded band and having more non-overlapping channels.
For these reasons ST addressed an a/b/g solution able to support simultaneously all this standards and developed the Band Interleaving Technology. |
