2. Introduction
JDTECK has engineered an advanced industrial grade digital repeater for
Distributed Antenna Systems with the ability to function in either a wideband
or narrow band mode. This core component helps create the perfect solution
for providing a wireless improvement in the cellular reception of a large office
or apartment building, hotel, underground parking garage or remote outdoor
location.
It is designed to improve the call quality of an area by receiving, amplifying,
filtering and re-transmitting the signals from the macro base station into a
specified area via a distributed antenna system (DAS.
This highly advanced digital unit uses a Graphic User Interface (GUI) to
access and select the desired active bands or channels, set any alarm trigger
points as well as configure and control the parameters of the repeater which
by extension controls the entire DAS it’s mated to either locally via USB or
remotely via Ethernet.
To maintain safe and specific output power levels, the GUI of this industrial
grade digital repeater has a wide range of configurable settings which allows
the repeater to function strictly within the parameters set by the end user.
These features include built-in Signal Oscillation Detection circuits with
color changing indicators for the respective bands (Green, Orange or Red
depending on the intensity), Automatic Gain Control (AGC) which will
dynamically reduce the gain of the repeater up to 10dB if oscillation or a high
input signal is detected. Manual Gain Control (MGC) to bring the repeater
into a set safe operating limit as well as a Network Safe / Auto MUTE
feature that immediately shuts-down the RF transmission circuit of any
frequency band that exceeds its set output power limits. There is also an
Uplink Sleep mode which shuts down the UL band of the repeater if no
activity is detected on the DAS after a set period of time. All features that
rigorously protect the macro cellular network from harmful interference.
There is master alarm indicator on the header of the GUI as well as an
external LED on the enclosure of the repeater which changes color from
green to red to alert the user if any alarm is detected. The user also has the
option to have the repeater send automatic email or SMS notifications to
specific addresses or numbers alerting the recipients to access the repeater
to make any needed adjustments.
This multiband industrial grade digital repeater from JDTECK is truly a very
user friendly, flexible and highly intuitive device that customers and system
integrators alike will enjoy using for many years to come.
