Important IEEE 802.11b and IEEE 802.11g use the same
radio frequency. IEEE 802.11a uses a different
radio frequency than IEEE 802.11b and
IEEE 802.11g. All wireless networking components
must use the same frequency. A combination of
IEEE 802.11a and IEEE 802.11b or IEEE 802.11a
and IEEE 802.11g components will not work.
Some wireless devices can broadcast and receive
signals on both frequencies.
A mixture of IEEE 802.11b and IEEE 802.11g
components will result in your network running at
the speed of the slower IEEE 802.11b
components.
Tips & Tricks When buying your access point router, be sure the
model includes everything your network needs,
including:
■
802.11g support - for next-generation,
high-speed wireless communications
■
Internet security features - such as a firewall to
protect your network from unwanted intruders
■
Wireless security features - such as 128-bit WEP
encryption
■
4-port switch - to eliminate the need for additional
network hardware
■
DHCP server/dynamic IP address assignment -
to automatically configure network and IP
addresses
