INTRODUCTION
Smart-Cell is a repeater, which has been designed to improve signals in blanket/shadow
areas inside of buildings to transmit Verizon’s signals at 700MHz, 850MHz, 1900MHz, and
2100MHz frequencies. User may choose filtering configuration according to the specific
site circumstances.

1.1.1
FCC Warning Statements
1) FCC Part 15.19 :
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including interference that
may cause undesired operation.
2) FCC Part 15.105 :
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the
Verizon User Manual
Smart-Cell Repeater
receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
3) FCC Part 15.21 :
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
4) RF Exposure :
This equipment is not enclosing antenna and not demand specific vendor of
antennas. Use an antenna as operator’s guidance. But, the antennas must be
installed such that a minimum separation distance of at least 130cm is maintained
between the radiator (antenna) and all persons at all times. This device must not be
co-located or operating in conjunction with any other antenna or transmitter.

Downlink/ Uplink Path The Smart-Cell repeater improves service in the 700MHz, 800MHz, 850MHz, 1900MHz and 2100MHz frequency bands. User may select frequency band according to the site peculiarities. After receiving a weak signal from donor antenna, the repeater improves and sends securely isolated signal out to service antenna. Amplifier unit is designed for correspondent operation with digital filter module (DFM). The AMP unit consists of a down and up converters, cavity filter and power amplifier (PAU). In Downlink Path, a weak RF signal is received from Donor Antenna. Being converted from RF to IF signal, it is transferred to the DFM, where after digitalizing by DA converter, signal is filtered by FPGA. After filtering digital, signal is converted into analog RF signal with modulator. Transmit to amplifier. Desirable signal is amplified and outputted through Service Antenna. Uplink path works vice versa. 10 Verizon User Manual Smart-Cell Repeater DFM

Quick GUI/Configuration Use the following steps to commission the Repeater after all the cabling and antennas are fixed in place and the Repeater is supplied with proper electrical power. The repeater will need a good quality stable Downlink RSSI input level in the range of 85dBm to -60dBm. 1) Connect your laptop to the repeater with a Crossover Ethernet cable. 2) Verify that your laptop has all wireless connections off and is Obtaining an IP address automatically, or is using a proper fixed IP address such as: Use the following IP address: 172.16.6.81 with a Subnet Mask of 255.255.255.252. 3) Open Internet Explorer and go to: 172.16.6.81 4) User name: admin 5) Password: admin 4.2.2. Quick Setup 1) Go to the RF Configuration page. 2) Before the Amplifier (HPA) can be turned on, set the Uplink and Downlink attenuation (ATT) to the maximum value and click Apply. 3) Select the correct Band Block and set the ALC Downlink and Uplink Limits to the desired level and click Apply. (To adjust the Output Power, change the ALC Downlink and Uplink Limits to the desired levels). 4) To check the Repeater’s status, click on the Status page. 5) To change the Repeater’s gain/attenuation, adjust the Uplink and Downlink attenuation in equal amounts not more than 5dB at a time and click Apply. 21 Verizon User Manual Smart-Cell Repeater 4.3.

Troubleshooting In case of abnormal operation, technician should diagnose abnormality via remote access or directly connecting to repeater using Ethernet cable. If technician is required to conduct repairs due to major alarm, repeater should first be powered off, and then technician should prepare the proper measurement equipment before trying to fix the problem. In most cases of major repairs, GST will simply replace the unit and conduct repairs at the appropriate facility. 4.4.1. Simple Troubleshooting Method 1) Verify LED Status, both on external LED’s as well as internal module LED’s - Normal operation: Green light on. Alarming: Red LED on. 2) Technician should check external and internal connectors to ensure that all connections are tightly secure. These connectors should be cleaned regularly. 3) If technician thinks there is a serious problem, call after sales team for over-thephone technical support. 1-866-9-GST-USA (1-866-947-8872) 4.4.2.
