30 Cellular Modem Installation Requirements
Section 3.6.1
Cellular Modem Installation Requirements
The cellular modem module is approved for modular use in mobile applications. The module, as part of the
RUGGEDCOM RX1500, can be integrated into a final product without additional certification from the Federal
Communications Commission (FCC) or Industry Canada (IC) if the application meets the following requirements:
NOTE
If this module is integrated into a portable device, separate approval related to the Specific Absorption
Rate (SAR) requirements of FCC Part 2.1093 and IC RSS-102 is required.
• Persons in the area must be kept at least 20 cm (8 in) from the antenna at all times.
• The antenna gain, including cable loss, must not exceed the maximum rating specified in Section 3.6.3,
“Supported Frequency Bands”.
• The cellular modem and antenna must not be next to or operate in conjunction with another transmitter or
antenna within a host device.
• A label must be affixed to the end product that indicates the FCC and IC IDs for the cellular modem.
Cellular Modem FCC ID IC ID
W11, W12 N7MC8705 2417C-MC8705
W21, W22 N7MC5728 2417C-MC5728
W32 N7MC8705 and N7MC5728 2417C-MC8705 and 2417C-MC5728
• The user documentation for the end product must clearly indicate the operating requirements and conditions
that comply with current FCC and IC radio frequency exposure guidelines.
• The end product must comply with the unintentional emission testing requirements of FCC Part 15.
If the application does not meet these requirements, further certification is required.
Section 3.6.2
Diversity Requirements
Diversity, where two antennas exist within the same physical housing, is a method for improving radio signal
strength. When two antennas are present, the following requirements must be met:
• Antenna isolation must be minimum 10 dB to prevent the receive antenna from picking up too much power
from the transmit antenna.
• Performance characteristics of the transmit and receive antennas must be comparable.
• The performance of the receive antenna, as measured by forward link throughput, must be 0 to 3 dB better
than a single antenna.
Section 3.6.3
Supported Frequency Bands
The following frequency bands are supported by the available cellular modem modules.
