What are potential factors that may causes interference among WLAN products?

Factors of interference:
1. Obstacles: walls, ceilings, furniture... etc.
2. Building Materials: metal door, aluminum studs.
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 setting. 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. Without
using an access point or any connection to a wired network.

What is Infrastructure mode?

Infrastructure mode implies connectivity to a wired communications infrastructure. If
such connectivity is required the Access Points must be used to connect to the wired
LAN backbone. Wireless clients have their configurations set for "infrastructure
mode" in order to utilize access points relaying.
