FCC COMPLIANT AND SAR INFORMATION
MTX-IND-V2 complaints with FCC regulations.
Equipment class: PCS Licensed Transmitter
Notes: Quad band GSM/GPRS Modem
MTX-IND-V2 Contains FCC ID: QIPTC65
Cinterion Wireless Modules models: TC63, TC65, TC63i and TC65i are marketed without defined antenna.
Maximum Gain antenna using indoor antennas depends on the distance from the antenna to any nearby
persons in normal operation and should not exceed values shown on the table below.
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
