client cards will work with 802.11g access points, and 802.11g client cards will work with
802.11b access points. Note that 802.11b products cannot be upgraded to support 802.11g
since the 802.11g radios use a different chipset than 802.11b devices. However, 802.11g
products and 802.11b products can work in the same network. Because 802.11g and
802.11b operate in the same unlicensed band, the two standards share the same three
channels, which can limit wireless capacity and scalability.
An 802.11a device and an 11b/g device cannot
communicate with each other.
The Wi-Fi standard certified at 2.4 GHz ensures the wireless interoperability with other
Wi-Fi (802.11b) certified devices.
