Document Purpose / Intended Users
The purpose of this document is to provide a step-by-step procedure to help the experienced
technician/engineer install and commission an in-building wireless enhancement system using
CSI’s “Wireless Engine” Digital Repeater. Following the procedures outlined will minimize risks
associated with modifying a live system and preclude service interruptions. This document
assumes the technician/engineer understands the basic principles and functionality involved
with Repeater and in-building systems. It is geared to the practical concerns of the installer.
Application
This guide should be applied whenever a need exists to add Digital Repeater capability to an
existing system or when this capability is being included with a new installation.
Safety Guidelines
The general safety information in this guideline applies to both operating and service personnel.
Specific warnings and cautions will be found in other parts of this manual where they apply, but
may not appear in this summary. Failure to comply with these precautions or specific warnings
elsewhere in the manual violates safety standards of design, manufacture, and intended use of
equipment. Cellular Specialties, Inc. assumes no liability for the customer’s failure to comply with
these requirements:
Grounding
This Digital Repeater system is designed to operate from 100-240 VAC @ 1.7A max. current
and should always be operated with the ground wire properly connected. Do not remove
or otherwise alter the grounding lug on the power cord.
Explosive Atmospheres
To avoid explosion or fire, do not operate this product in the presence of flammable
gases or fumes.
Lightning Danger
Do not install or make adjustments to this unit during an electrical storm. Use of a suitable
lightning arrester, such as CSI’s model number CSI-CAP, is very strongly recommended.
No User Serviceable Parts Inside
HAZARDOUS VOLTAGES ARE PRESENT WHEN THE COVER IS REMOVED. Opening the
chassis will void your warranty. If you suspect a malfunction with this product, call your dealer or
the Cellular Specialties Support Line at: (603) 626-6677.

Important Safety Information
Antennas used for the purpose of radiating signals indoors are limited to a maximum gain of 3dBi. 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 equals 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 seperation distances.
INDOOR antennas must be placed so that under normal conditions, personnel cannot come within 20
cm (8.0 in.) from any inside antenna. Adhering to this minimum separation will ensure that the employee
or bystander cannot exceed RF exposures beyond the maximum permissable limit as defined by section
1.1310 i.e. limits for General Population / Uncontrolled Exposure.
OUTDOOR antenna must be positioned so that under normal conditions, personnel cannot approach
closer than 120 cm (4 ft.). A directional antenna having a maximum gain of 14 dBi is used, and precautions should be taken to prevent personnel from routinely passing through the main radiation beam at a
distance closer than specified.
Product Introduction
The SMR-700/800 Repeater has been developed for use within enclosed structures where signal from
local cell sites to operate cell phones is poor or unavailable. Adequate signal must be available outside the
structure as a prerequisite to achieving in-building coverage. The SMR-700/800 Repeater is connected 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 SMR-700/
800 Repeater amplifies 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 +80dB nominal gain on both the up and down links, gain can be adjusted over a
range from +50dB to +80dB in 1.0dB steps. Control of the repeater is achieved utilizing a computer
connected to comm. port 1 or 2 or via Ethernet cable connected to the Ethernet port. There are also LED
indicators to indicate ALARM status, OSC, and Power.
Product Features
• Easy Installation, Small, Light weight, Single Unit T ype Housing
• Built-in AGC, ALC, and an Easy to use Auto Shut Down Function
Special Installation Directions
• SMR-700/800 Repeater has been designed to be used in a limited area.
• Electric shock may occur if repeater is installed in close proximity to water.
• Keep the unit clean and dust free during installation.
• Do not place cables or tools in close proximity to the repeater that may damage it.
• Do not wear jewelry, watches, or any type of metal accessories when installing the unit.
• Check the installation site for hazardous conditions, such as water covered floors,or badly
worn or damaged cables, prior to installation.
• Lifespan and performance of the repeater may be reduced if the unit is operating outside
of its temperature range.
• Opening or disassembling the repeater will render its warranty void.

Function Block diagram
The function of the SMR-700/800 is as indicated in the block diagram above.
• Multiplexer Block: combines several different frequencies into one or divides several
different frequencies, combines and transfers the Network and iDEN A, or iDEN B, and
transfers the DL and UL signal separately.
• LNA/AGC Block: Amplifies the low end signal coming from the antenna while
minimizing noise.
• Up/Down Converter Block: Made up of a Mixer and an IF SAW Filter. It converts
frequencies to different frequencies that utilize better filter performance.
• HPA/DRV AMP Block: A power amplifier for the repeater’s high output, high gain and
high linearity.
• PLL Block: Localizes signal for Up/Down converting.
• CPU Block: Controls all repeater functions
• PSU Block: Power supply receiving 110AC volts and converting it to +24VDC and +6VDC.
