  2. 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’simplementationlosses: 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. Hernandez,Li,Dotlić (NICT)

  3. Path Loss Estimate The maximum allowed path losses are: L1 = 114.97 dB for 1 Mbps and L2 = 120.98 dB for 250 kbps Hernandez,Li,Dotlić (NICT)

  4. Path Loss Estimate • Free path loss (in Matlab format): PL = 20*log10(4*pi*fc*d/3e8); • Fc=2.4 GHz, D=100m, PL=80.0460 dB • Fc=2.4 GHz, D=200m, PL=86.0666 dB • Fc=2.4 GHz, D=500m, PL=94.0254 dB • Fc=5.1 GHz, D=100m, PL= 86.5932 dB • Fc=5.1 GHz, D=200m, PL= 92.6138 dB • Fc=5.1 GHz, D=500m, PL= 100.5726 dB Hernandez,Li,Dotlić (NICT)

  5. Path Loss Estimate • ITU outdoor path loss model • lamda=3e8/fc; Lbp=abs(20*log10((lamda^2)/(8*pi*hb*hm))); Rbp=(4*hb*hm)/(lamda); if d<=Rbp PL=Lbp+20*log10(d/Rbp); else PL=Lbp+40*log10(d/Rbp); end Hernandez,Li,Dotlić (NICT)

  6. 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)

  7. 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.
