Installing the Device
NOTE
A specific brand of antenna is not specified.
To install the LTE and/or GPS antennas, do the following:
WARNING!
Radiation hazard – risk of Radio Frequency (RF) exposure. This device is compliant with the
requirements set forth in FCC 47 CFR, section 1.1307, addressing Radio Frequency (RF) exposure
from radio frequency base stations, as defined in
Bureaus/Engineering_Technology/Documents/bulletins/oet65/oet65.pdf]. The emitted radiation should
be as little as possible. To achieve minimum RF exposure, install the device when it is configured not
to transmit and set it to operational mode remotely, rather than having a technician enable transmission
on-site. For maintenance of the base station, or other operations which require RF exposure, the
exposure should be minimized in time and according to the regulations set forth by the country of
installation or the Federal Communications Commission (FCC).
WARNING!
The device must be placed at a distance of at least 20 cm (8 in) from all persons during normal
operation. The antennas used for this product must not be located or operating in conjunction with any
other antenna or transmitter, except in accordance with FCC multi-transmitter evaluation procedures.
CAUTION!
Configuration hazard – risk of reduced performance. Each antenna and connecting cable must have a
nominal impedance of 50 Ω with a return loss of better than 10 dB across each frequency band. If the
nominal impedance is different, Radio Frequency (RF) performance will be reduced.
IMPORTANT!
The antenna installation must be as per Article 810 of the NEC. Specifically, the grounding conductor
must not be less than 10 AWG (Cu). The scheme should be either:
• In accordance with UL 96 and 96A Lightning Protection Components and Installation Requirements
for Lightning Protection Systems (LPS)
• Tested in accordance with UL 50 and UL 497
IMPORTANT!
A Radio Frequency (RF) site survey is recommended prior to any installation to help determine the
best location for the LTE and GPS antennas. For assistance, contact a Siemens Sales representative.
IMPORTANT!
The cellular modem supports SISO (Single Input Single Output) and MIMO (Multiple Input Multiple
Output) modes. At minimum, a single antenna connected to the LTE MAIN port is required for SISO
mode and to support lower generation wireless standards, such as GSM or EDGE. A separate diversity
(secondary) antenna is required for MIMO performance.
IMPORTANT!
For mobile and fixed operating configurations, in accordance with FCC 47 CFR, section 2.1091, the
antenna gain, including cable loss must not exceed:
• 6.5 dBi at 800/850 MHz
• 3.0 dBi at 1900 MHz
