P-2608HWL Series Support Notes
3. Electrical devices: microwaves, monitors, electric motors.
Solution :
1.Minimizing the number of walls and ceilings
2.Antenna is positioned for best reception
3.Keep WLAN products away from electrical devices, eg: microwaves, monitors, electric motors,..., etc.
4. Add additional APs if necessary.

What's the difference between a WLAN and a WWAN ?

WLANs are generally privately owned, wireless systems that are deployed in a corporation, warehouse,
hospital, or educational campus. Data rates are high and there are no per-packet charges for data
transmission.
WWANs are generally publicly shared data networks designed to provide coverage in metropolitan areas
and along traffic corridors. WWANs are owned by a service provider or carrier. Data rates are low and
charges are based on usage. Specialized applications are characteristically designed around short, burst
messaging.
What is Ad Hoc mode ?
A wireless network consists of a number of stations without access points or any connection to a wired
network.

What is Infrastructure mode ?

Infrastructure mode implies connectivity to a wired network infrastructure. If such connectivity is
required, an Access Points must be used to connect to the wired LAN. Wireless clients must also use
"infrastructure mode" in order to access the network through the access points.

How many Access Points are required in a given area ?

This depends on the surrounding terrain, the diameter of the client population, and the number of clients.
If an area is large with dispersed pockets of populations, then extension points can be used for extending
coverage.

What is the Direct-Sequence Spread Spectrum (DSSS) Technology ?
