Antennas used for the purpose of radiating signals indoors are limited to a maximum gain of 3 dBi. The outdoor antenna used
for the purpose of communicating to the wireless infrastructure is limited to 14dBi gain, or any combination of gain and loss that
equates to 14dB at input. Each antenna must be positioned to observe minimum separation requirements from all users and
bystanders. The following guidelines should be used when considering separation distances.
INDOOR antennas must be placed such that, under normal conditions, personnel cannot come within 20 cm (~0.65 ft.)
from any inside antenna. Adhering to this minimum separation will ensure that the employee or bystander cannot exceed RF
exposures beyond the maximum permissible limit as defi ned by section 1.1310 i.e. limits for General Population/Uncontrolled
Exposure.
OUTDOOR antenna must be positioned such that, under normal conditions, personnel cannot approach closer than 122 cm.
(~4 ft.). A directional antenna having a maximum gain of 14 dBi is used, precautions should be taken to prevent personnel from
routinely passing through the main radiation beam at a distance closer than specifi ed.
Important Safety Information
Product Introduction
Cellular Specialties, Inc. (CSI) developed the CS17-145-410 LTE - 700 U7C repeater for use within enclosed structures where
signal strength from the local cell site is insuffi cient to operate mobile phones. Adequate signal must be available outside the
structure as a prerequisite to achieving in-building coverage. The Repeater is connected via coax cable to an external antenna,
usually on the roof, and to one or more internal antennas placed strategically throughout the area where wireless service is
desired.
The external antenna typically is directional, such as a “yagi”. Internal antennas are typically omnidirectional, although various
other types may be used depending on the coverage application. The Repeater amplifi es both the “uplink” (phone to tower) &
“downlink” (tower to phone) signals thus facilitating communications to and from the intended wireless infrastructure.
With a maximum total of +85dB nominal gain on both the up and down links, gain can be adjusted over a range 30dB in 1.0dB
steps. Control of the repeater is achieved utilizing a computer connected to the NMS 9 pin D-Sub RS323C port. This model is
designed to cover the Upper C portion of the LTE 700 MHz band.
