Features

The JDBS line of Indoor Band Selective 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, avoiding 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, 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 and other parameters by use of IP interface via a USB port. The JDBS line of Indoor Repeaters are designed 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 stabilizes the coverage area size, but also prevents intermodulation from becoming worse
and thus minimizes the interference to the mobile network.

2) AGC (Automatic Gain Control - 15dB 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 isolation is not enough.

3) Uplink Intermodulation:

These values always meet ETSI Standards and 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 service antennas
is not enough. The manual gain control range is 31dB with 1dB per each step. This is realized by local software control with USB port, or optional remote control via
SMS or GPRS Modem.

5) Alarm LED Display:

This is a power LED indicator and color changing Alarm LED indicators that detects when errors occur.

6) Local Software:

This narrow band selective repeater comes standard with a USB Port and local software to control the parameters. Actions include; Alarm Enable, Alarm Message, UL / DL Gain Adjustment, Output Power etc...
