Can I play multi-player games with other players over a wireless network?
Which IEEE802.11b features are supported?
What is the ad-hoc/infrastructure mode?
What is roaming?
What is the ISM band?
What is spread spectrum?
A-2
Yes, as long as the game can be accessed by multi-players over a
network (LAN). Please refer to the documentation for the game.
The following functions are supported:
•
CSMA/CA plus acknowledge protocol
•
Multi-channel roaming
•
Automatic Rate Selection (ARS), automatic setting of the data rate
•
Power management
If computers work in the ad-hoc mode, they communicate
directly with each other, in contrast to the infrastructure mode
where the complete communication is performed via the access
point.
Roaming is the capability to log on clients to various access points
while moving through wireless cells without the user noticing it. If
the client leaves the reach of an access point, it automatically looks
for the next best-suited access point under consideration of differ-
ent parameters, such as signal strength or cell utilization.
Approvals agencies have defined a free frequency band which can
be used almost worldwide. The 2.4 GHz ISM band (Industrial,
Scientific, and Medical) can be used almost worldwide.
Spread spectrum is a spread band procedure which was originally
developed for military purposes. Also see DSSS and FHSS in the
glossary.
