Features

The JDCS (Double Band Channel Specific) line of Indoor Cellular Repeaters are designed specifically with service operators in mind. These gain adjustable units are perfect for providing wireless coverage within an office building, restaurant, warehouse, underground parking lot or VIP room of your allocated bandwidth and avoid a competitor’s network. Several models are available to support any frequency band or technology around the world.

These units are fully customizable, making design and installation and integration of an indoor system extremely easy. With the use of RF Signal splitters, combiners, couplers and indoor antennas, we can design a solution that fits your specific needs.

By making use of the latest Gain Adjustable Technology available today, this repeater allows the user to manually increase or decrease the Uplink & Downlink gain levels individually, by use of a Dipswitch to attenuate the gain. The JDCS line of Indoor Repeaters are design to be transparent to the network and will therefore support the same number of calls the BTS in the area can support. The JDCS Repeater is relatively lightweight and compact enough that it can be placed within an electrical closet where space is limited.

Main Features Include:

1) ALC (Auto Level Limit Control):

When the power level of the Uplink and Downlink becomes higher than the peak output power
of the repeater due to stronger input power level, the system will automatically limit its power level.
It not only stabilzes the coverage area size, but also prevents intermodulation from becoming worse
and thus minimizes the interfarence to the mobile network.

2) AGC (Automatic Gain Control - 20dB Range):

This feature directly controls the gain of the repeater, Uplink and Downlink, to help achieve the ALC function.
It also works to avoid self-oscillation when isolaiton is not enough.

3) Uplink Inter-Modulation:

These values always meet ETSI Standards or 3GPP to minimize interference to the mobile network.

4) Manual Gain Control (31dB Range):

The Manual Gain Control function helps users achieve the suitable output power level necessary for the
covered area and helps to avoid self-oscillation when physical isolation between donor and services antennas
are not enough. The manual gain control range is 31dB with 1dB per each step. This is realized by DIP switches
or buttons and a digital panel, local software control with RS232 interface, or even remote software control
depending on the different repeater models.

5) Alarm LED Display:

This is a power LED indicator and color chnaging Alarm LED indicators that detects with errors occur.

6) OMT Software (Optional):

Some repeater models have OMT software for local or remote monitoring and control, by which the repeaters's
working status and alarms can be monitored and some of the repeater's settings configured.

Customizable Bandwidth

With the use of SAW filters this JDCS Repeater can be customized to support up to any (3) Non Continuous Segments of channels and existing frequency hopping technology within a specific frequency band or up to (2) different bands and reject all competitors signals. Any amount of sample units can be purchased for testing, evaluation or deployment with competitive lead times. Discounts can be offered for large quantity purchases.
