The IEEE802.11b standard is compatible with the existing IEEE802.11 standard. The wireless frequency uses the 2.4 GHz band, and the transmission speed can be increased from 2 Mbps to a theoretical maximum of 11 Mbps. Data communication is possible in a wide range even in the house, and it can be used stably because there is little interference with other devices that use radio waves.
Like IEEE802.11g, it can be used in public spaces (stations, public institutions, lodging facilities, cafes, etc.) with wireless LAN access points called free spots.
*The maximum transfer speed is a theoretical speed. Effective speed may be slower due to communication procedures, etc.
IEEE802.11b can use 12 channels from 1ch to 11ch and 14ch. Note that IEEE802.11g, which is backward compatible, has 11 channels from 1ch to 11ch.
