Glossary
Group ID
/
BSSID
A Group ID (the 802.11 standard uses the term BSSID) is the ID of a wireless cell.
A wireless cell is usually made up of stations in an area that the radio signal can
comfortably cover. In other words, any wireless station in the cell can
communicate with any other within reach of the radio signal.
Domain Name / ESSID
A “Domain” is most commonly used to refer to a group of computers whose
hostnames share a common suffix. The domain is usually defined by the network
administrator as a segment/subnet of a large network and may be made up of
overlapping wireless cells. Wireless nodes can roam freely within the same
domain without disconnecting from the network.
Roaming
The convenience of a mobile PC is the ability to move freely. The concept is
similar to that of a cellular phone moving from one base station to another.
InstantWave High Rate offers built-in high performance and seamless roaming
capabilities.
Regulatory Domain
InstantWave High Rate products use the unlicensed ISM (Industrial, Scientific,
Medical) band to communicate through radio waves. Different countries offer
different radio frequencies to be used as the ISM band. There are four frequency
bands defined by 802.11: Japan (2.471GHz – 2.497 GHz), USA, Extended Japan,
Canada, and Europe (2.4 GHz – 2.4835 GHz), Spain (2.445 GHz – 2.475 GHz),
and France (2.4465 GHz – 2.4835 GHz). To use InstantWave High Rate in a
country not listed above, check with your government’s regulating body to find the
correct frequency band to use. All InstantWave High Rate products are supplied
preset to the country of sale’s frequency band.
