SAR INFORMATION
Cinterion Wireless Modules models: Modem TC and GSM65 are marketed without defined antenna.
Maximum Gain antenna using indoor antennas depend on distance from antenna to any nearby
persons in normal operation should not exceed values shows on below table.
According to the limit in 47 CFR 1.1310, we get the value of the maximum antenna gain as follow:
The maximum measured power output in the 850 MHz band is 1866.38 mW (32.71 dBm, see 7layers
test report MDE_Siem_0714_FCCb).
The maximum permissible exposure is defined in 47 CFR 1.1310 with 0.55773 mW/cm².
The maximum measured power output in the 1900 MHz band is 974.99 mW (29.89 dBm, see 7layers
test report MDE_Siem_0714_FCCc).
The maximum permissible exposure is defined in 47 CFR 1.1310 with 1 mW/cm².
According to the limit in 47 CFR 1.1310, we get the value of the maximum antenna gain as follow:
S = P*G/4
π
R²
S = 0.55773 mW/cm² or 1 mW/cm²
P = 1866.38 mW or 974.99 mW
R = 20 cm or 100cm
π
= 3.1416
G(dBi)=10*log10(G)
Solving for G; the maximum antenna gain is
