The JDCR-LGDW Indoor Cellular Repeater is a medium-powered, 5 Band gain adjustable repeater that is perfect for providing wireless coverage to an office building, department store, warehouse, underground parking lot, or multi-story building. Our repeaters help mitigate less than desirable PN scans in RF polluted environments thru the use of high linear amplifiers, properly specified output power limits and a well designed alarm/protection circuitry.
A certified test report is included with each repeater that leaves our factory, so you are assured of strict quality controls.
The JDCR-LGDW 5 Band Cellular Repeater is a medium-powered, gain adjustable, triple band repeater that is perfect for providing wireless coverage inside a large home, office building, restaurant, warehouse, underground parking lot, VIP room, etc. Designed with European networks in mind, this repeater supports 5 frequency bands, making it very convenient. (800 / 900 / 1800 / 2100 / 2600 MHz). The JDCR-LGDW unit is also fully customizable, making design and installation of an indoor system extremely easy. With the use of RF directional couplers and indoor antennas, we can design a solution that fits your specific needs. A typical unit can easily cover up to 55,000 sq ft.
To maintain safe and specific output signal levels, this advanced repeater has built-in AGC and ALC circuits, which can automatically control the gain of the repeater within a 15dB range depending on environmental conditions. In addition, it also has built-in attenuation dip switches that allow you to manually attenuate (fine tune) the repeater’s uplink and downlink channels in 1db steps up to 31dB, using color changing LED’s as a status indicator. These Alarm LED’s are used as a guide to prevent your installation from re-producing errors due to excessive input signal strength if a pre-amp is used, or from signal oscillation due to the indoor antenna and outdoor antenna being too close to each other, which can have adverse effects on a base station.
A Network Safe / MUTE™ feature comes standard with this repeater to protect the cellular network. In short, the repeater will stop transmitting if any errors or signal oscillation is detected within 2-4 sec of detection. It will cycle for 30 sec then attempt to transmit again. If no adjustment in gain has been made to correct the error within the 30 sec MUTE cycle, the system will again shut down after 5 sec. It will run this sequence for a total of 3 times and then shut down completely. Unplugging and powering back up the unit will reset this sequence
The JDCR-LGDW Indoor Repeater is designed to be transparent to the network and will therefore support the same number of calls the BTS in the area can support. It is also compact enough that it can be placed within an electrical closet where space is limited.

The level of Andy and Angel were amazing! They did our installation, and it was immaculate. They were professional, knowledgeable, and very meticulous. Best vendor I’ve ever worked with bar none! Professional customer service and technical knowledge was unmatched. JDTECK is always welcomed here at the Embraer Engineering & Technology Center USA. We hope to continue this partnership in the near future
From the beginning of the project JDTECK consistently impressed us with their knowledge and understanding of the technologies they produce and deploy. Their installations were consistently excellent and professional!
The level of professional customer service and technical knowledge was unmatched. JDTECK is always welcomed here at the Embraer Engineering & Technology Center USA. We hope to continue this partnership in the near fuI would like to take this opportunity to acknowledge JDTECK for exceeding our expectations in the design and installation of a DAS (Distributed Antenna System) for the MCU (Marine Corps University) Bldg. M285 located at Camp Johnson North Carolina
The level of professional customer service and technical knowledge was unmatched. Polk County Florida Roads and Drainage Division Complex is located in a very remote area with limited access to cell service in various areas. After installation of 5G cell service boosters, employees now enjoy an outstanding connection with their cell phones that was not possible before. Sales, design and installation were outstanding!TECK is always welcomed here at the Embraer Engineering & Technology Center USA. We hope to continue this partnership in the near future
In 2012 we found JDTECK and gave them a shot. Since then, we have never turned back. The equipment is quality, and meets all expectations, but most importantly the customer service, attention to detail and passion that goes into every single job, purchase etc is handled better than I could ever expect. I would highly recommend giving them a shot, and exploring their products, they will not disappoint
JDTECK did an amazing job with our 100,000 sq. ft. corporate HQ building. Large areas of the building experienced medium-to-poor reception, with frequent dropped calls and cell phone batteries constantly draining. When JDTECK finished, we showed full bars for all areas of the building. We actually get better signal strength inside the office than we do in the parking lot! Highly recommended!
The level of professional customer service and technical knowledge was unmatched. JDTECK is always welcomed here at the Embraer Engineering & Technology Center USA. We hope to continue this partnership in the near future
Your techs have been amazing! We wish all projects here were as seamless as this one. We tested the entire building, and it works well…
