 | | Metal, water, and thick walls absorb 802.11b signals and decrease the range drastically. |
 | | With high-gain external antennas, the protocol can also be used in fixed point-to-point arrangements, typically at ranges up to 8 kilometers (although some report success at ranges up to 80-120 km where line of sight can be established). |
 | | Extensions have been made to the 802.11b protocol (e.g., channel bonding and burst transmission techniques) in order to increase speed to 22, 33, and 44 Mbit/s, but the extensions are proprietary and have not been endorsed by the IEEE. |
