IEEE 802.11g Wireless LAN
IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE
802.11b radio card can interface directly with an IEEE 802.11g access point (and vice versa) at
11 Mbps or lower depending on range. IEEE 802.11g has several intermediate rate steps
between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation
are as follows:
" Your device may be prone to RF (Radio Frequency) interference from other
2.4 GHz devices such as microwave ovens, wireless phones, Bluetooth
enabled devices, and other wireless LANs.
The following list, which is not exhaustive, illustrates the standards supported in the ZyXEL
Device.
