Wireless Terminology

Wireless Standards

802.11, 802.11b and 802.11g all refer to a series of standards which govern a common method of creating wireless local area networks (WLANs).

802.11b and 11g are the most common WLAN types, with 11g being the later and faster of the two standards with a maximum transmission rate of 54Mbps.

The NP644 is faster again as it is built around a processor which ‘turbo-charges’ transmission rates up to 108Mbps.

802.11g is ‘backward compatible’ with 802.11b, which means that the two standards are able to communicate, albeit at the lower 11Mbps rate of the 11b standard.

The NP644 can communicate with both kinds of device at their maximum rate, and with other ‘turbo-charged’ devices at the much higher rate of 108Mbps.
