OFDM - Faster 802.11a
Wireless LAN Technology
Frequency Division Multiplexing) defines the technology that divides a
frequency band into multiple segments and then modulates each
individual frequency segment with a different code, thus able to
get more capacity out of the same spectrum.
These OFDM chips are
being used to create wireless LANs that run at higher speed as
compared to 802.11b - 54 to 72 Mbps instead of 11 or 22 Mbps.
These faster IEEE
802.11a wireless LANs will operate in 5 to 6 GHz unlicensed band
as compared to 2 to 2.4 GHz ISM band for existing wireless LANS
where they compete with microwave ovens, 2.4-GHz cordless
phones, and other technologies such as Bluetooth and HomeRF.
planners are conceptualizing metro area wireless networks and 4G
wireless networks based on this
OFDM Chips started
production in 3Qtr 2001 - Atheros was among the first vendors to
consumption than 802.11 2.4 GHz chips
