MTX M2M® by MATRIX ELECTRONICA S.L.U
10.1 FCC Compliant
MTX-IoT and any variants contain FCC ID: QIPEHS6. The FCC Equipment Authorization Certification for
the EHS6 Module is listed under the FCC identifier QIPEHS6
Industry Canada Certification Number: 7830A-EHS6 granted to Gemalto M2M GmbH.
The Cinterion reference application of the EHS6 Module registered under the above identifier is
certified to be in accordance with the following Rules and Regulations of the Federal Communications
Commission (FCC). Power listed is ERP for Part 22 and EIRP for Part 24. It is compliant with FCC
regulations.
Equipment class: PCS Licensed Transmitter
Notes: Quad band GSM/GPRS Modem
10.1.1 SAR information
Cinterion Wireless Modules models: EHS6 is marketed without a defined antenna.
The Maximum Antenna Gain when using indoor antennas depends on the distance from the antenna
to any nearby persons when in normal operation. It should not exceed the 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 follows:
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 as 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 as 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 follows:
S = P*G/4πR²
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
Band Distance Maximum Gain in dBi
850MHz 20cm 1.7669
850MHz 50cm 9.7257
1900MHz 20cm 7.1227
1900MHz 50cm 15.0815
