802.11b/g
802.11b, 802.11g and 802.11n all operate in the 2.4GHz band.
802.11b can support data rate up to 11Mbps. 802.11g can
support data rate up to 54Mbps. 802.11n can support data rate
up to 300Mbps.They all support the widest coverage – up to
100m (328ft). It is however, subject to a greater risk of radio
interference because it operates in the more popular 2.4GHz
band.
