Hi all, Actually I found from the internet that transmission power = 0.2818 W provides 2Mbps bandwidth. However, I cannot find the other values for transmission power = 8.5872e-4and 7.214e-3. I appreciate any help.

To: [email protected] Hi all, How can I map transmission power with the value of bandwidth? I am working about the transmission power in wireless network. I am also using shadowing propagation model with transmission power = 0.2818 Watt, which provides 250m communication range. The other mapping between transmission power and range are From wireless-phy.cc Pt_ = 8.5872e-4 // For 40m transmission range. Pt_ = 7.214e-3 // For 100m transmission range. Pt_ = 0.2818 // For 250m transmission range. This is the model of AT&T's Wavelan PCMCIA card. However, I would like to map each transmission power with the transmission rate , such as 54, 11, 5,2,1 Mbps,etc. Can I do that? Do you know the reference of this default power (0.2818)? Any suggestions and hints are welcome. Thank you in advance, Sincerely, Chakkaphong S. -- \(^0^)/ Tor.....(จุ๊กก้า)..........
