Wireless
Network Update
In our September, 2002 issue of The Next
Wave, we described the two main standards at the time, 802.11a and
802.11b. Proving once again
that the only thing certain in the world of computers is change, there
will shortly be a new standard, 802.11g.
Like the “b” standard, the “g” standard operates in the
2.4-Ghz radio spectrum thereby providing backward compatibility with the
“b” products on the market.
The
advantage is that it can operate at a theoretical speed of 54 Mbps very
similar to the “a” standard. In
reality, throughput is between 15 to 20 Mbps which is still acceptable
for many computing applications. Except
for special circumstances, we predict that the “g” will be the
winner because it does somewhat better at distances further from the
access point (performance drops noticeably when the wireless device is
more than 100 feet from the access point).
If
you want to hedge your bets, LinkSys model WRT55AG supports all three
standards. Note that
performance drops considerably if you run both “b” and “g”
clients simultaneously in mixed mode.
The best performance is to have only “g” devices on the
network so that the access point can run “g” native.
