November 2012 Path Loss Estimate Maximum transmit power at the input antenna: Pt=250 mW. Antenna gains are assumed as Gt = Gr = 0 dBi. The fade margin: Fm = 6 dB. Receiver’s implementation losses: Il = 3 dB. Receiver’s noise figure: NF = 6 dB. Through simulations a candidate system: Eb/N0 = 8 dB for BER= 10-3. Data rate: 1 Mbps, 250 kbps.

Path Loss Estimate ITU outdoor path loss model November 2012 Path Loss Estimate ITU outdoor path loss model Fc=2.4 GHz, D=100m, PL= 76.8787 dB Fc=2.4 GHz, D=200m, PL= 88.9199 dB Fc=2.4 GHz, D=500m, PL=104.8375 dB Fc=5.1 GHz, D=100m, PL= 80.5726 dB Fc=5.1 GHz, D=200m, PL= 88.9199 dB Fc=5.1 GHz, D=500m, PL= 104.8375 dB Hernandez,Li,Dotlić (NICT)

November 2012 Path Loss Estimate For a distance of 500m, and Fc=2.4Ghz and 5.1 GHz, the computed path losses do not reach the maximum allowed path loss (L1 = 114.97 dB for 1 Mbps and L2 = 120.98 dB for 250 kbps) that will degrade performance for this particular system. This is a proof of concept that a transmission range of 500m is feasible for the 2.4 GHz band and 5.1 GHz bands. Hernandez,Li,Dotlić (NICT)
