Wireless Standards

Wireless-B (802.11b) - Operates on the 2.4GHz frequency band and can transmit data at speeds of up to 11Mbps within a range of up to 100-150 feet. Wireless range can be affected by reflective or signal-blocking obstacles, such as mirrors, walls, devices and location, whether indoors or outdoors.

Wireless-A (802.11a) - Operates at the frequency of 5GHz, which is less crowded than 2.4GHz where telephones and microwaves may cause interference. Although the speed is up to 54Mbps, the range is only up to 75 feet. Wireless-A is incompatible with both Wireless-B and G because it operates at a different frequency.

Wireless-A+G (802.11a + g) - Linksys also offers dual-band products, in which routers and adapters are compatible with both 2.4GHz and 5GHz frequencies. Both radio bands work simultaneously, blanketing your wireless zone and bandwidth.

Wireless-G (802.11g) - Features the same benefits as Wireless-B, but offers 5X the speed at up to 54Mbps. Wireless-G currently offers the best combination of performance and value. You can mix Wireless-B with Wireless-G equipment, but you will lose the higher performance speeds of Wireless-G.
The chart below outlines the differences and features for each wireless standard, along with the activities that are best suited for each one.
