allow radio waves to pass through. Metals reflect radio waves and concrete
attenuates radio waves. The amount of attenuation suffered in passing through
concrete will be a function of its thickness and amount of metal re-enforcement
used.

11. 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.

12. 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.

13. Can I manually swap the wireless module without damage

any hardware?

Yes, it will not harm the hardware, but the module will not be detected and
work after inserting to the slot. You need to reboot the router to initialize the
module.
