Domain Name/ESSID
A 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.
Figure 4 depicts a common wireless network setup.
FIGURE 4. ROAMING IN THE SAME DOMAIN
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 offers built-in high performance seamless roaming capabilities.
Carrier Set
InstantWave 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 802.11b: Japan (2.471GHz – 2.497 GHz), USA, Canada, and Europe (2.4
GHz – 2.4835 GHz), Spain (2.445 GHz – 2.475 GHz), France (2.4465 GHz –
2.4835 GHz). If a user wants to use InstantWave in a country not listed above,
he/she needs to check with their government’s regulating body to find the correct
frequency band to use. All InstantWave products are supplied preset to the country
of sale’s frequency band.
