The 802.11g WLAN standard has
been recently ratified by the IEEE. This new standard
runs at 54 Mbps and is almost five times faster than
the prevailing 802.11b, which runs at 11 Mbps.
802.11b-based WLAN products
have already gained a lot of market share in India and
increased by 120 percent from 2001 to 2002 worldwide.
The high data rates of 802.11g should encourage more
enterprises and individuals to use WLAN solutions. The
new standard is also backward-compatible with the old
802.11b, and will thus interoperate with any existing
802.11b equipment.
802.11g transmissions use the
2.4GHz frequency range. And this range is also shared
by 802.11b, Bluetooth devices, and cordless phones.
Although products based on
802.11g have been around for a while, users have been
hesitant to purchase them due to the lack of ratification.
This news should remove any inhibitions.
However, another WLAN standard,
802.11a also offers 54 Mbps, but suffers less from interference
mainly because it uses the 5GHz frequency range. A disadvantage
is that it isn't backward compatible with 802.11b. The
popular choice of enterprises and individuals remains
to be seen.
