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.

16. 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.

17. 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.

18. Can I manually swap the wireless module without damage any

hardware?

Yes, manually swap will not harm the hardware, but the module will not be

detected and work after inserting to the slot. You need to reboot the

P-660HW-Tx v2 to initialize the module.

19. Does P-660HW-Tx v2 support WEP?

Yes, P-660HW-Tx v2 supports 64-bit/128-bit/256 WEP.

20. What wireless standard does P-660HW-Tx v2 support?

It supports IEEE 802.11b/g/g+ standard.

21. Does P-660HW-Tx v2 support MAC filtering?

Yes, it supports up to 32 MAC Address filtering.
