we need to place a access point on floor. For 1 Mbps it works for 450 feet. Now walls are constructed with Mi-one tech.
I need a document from which i can get information about strength of signal or obstacals that might degrade signals
please guide us

Hi Pushpak,
Signal attenuation or signal loss occurs even as the signal passes through air. The loss of signal strength is more pronounced as the signal passes through different objects. A transmit power of 20 mW is equivalent to 13 dBm. Therefore, if the transmitted power at the entry point of a plasterboard wall is at 13 dBm, the signal strength will be reduced to 10 dBm when exiting that wall.Here some examples;
Plasterboard wall Signal Attenuation 3 dB
Glass wall with metal frame Signal Attenuation 6 dB
Cinder block wall Signal Attenuation 4 dB
Office window Signal Attenuation 3 dB
Metal door Signal Attenuation 6 dB
Metal door in brick wall Signal Attenuation 12 dB
Human body Signal Attenuation 3 dB
From this good site survey doc;
Hope this helps!
Rob
