802.11g
In 2002 and 2003, WLAN products supporting a newer standard called 802.11g emerged on the market. 802.11g attempts to combine the best of both 802.11a and 802.11b.
802.11g supports bandwidth up to 54 Mbps, and it uses the 2.4 GHz frequency for greater range. 802.11g is backward compatible with 802.11b, meaning that 802.11g access points will work with 802.11b wireless network adapters and vice versa.
- Pros of 802.11g – Fast maximum speed; signal range is good and not easily obstructed.
- Cons of 802.11g – Costs more than 802.11b; appliances may interfere on the unregulated signal frequency.
