JDTECK’s all-in one Quad Band Digital Repeater can operate in either a pre-set channelized mode, wide-band mode or custom-band mode with just the click of a mouse. This high-powered, gain adjustable, quad band digital repeater is perfect for use in a DAS needing to provide enhanced coverage for all the major Wireless Service Providers (WSP’s) simultaneously while yet being able to individually adjust each carrier’s gain and output power level.
Using a Small Cell as your signal input source for one WSP while another provider’s source feed might be OTA (Over The Air) is easy to configure with this advanced digital repeater from JDTECK. Deploying a DAS in a dense metro environment where one WSP’s tower is right across the street thus over-powering some of your inputs, while another provider’s signal is coming in very weak is exactly what this unit is capable of balancing out . With up to 40 dB of on-board manual attenuation in the GUI itself, plus an additional 10 dB of Automatic Gain Control (AGC), fine tuning and balancing all your outputs for each carrier is very quick, easy and accurate. Our repeaters are built with carrier level optimization in mind. Therefore, only the highest quality components are used which maintains very good RSRQ, RSRP and SINR values throughout the DAS.
The highly intuitive Graphic User Interface (GUI) allows the user to select the desired active bands or channels they want to amplify, turn down or even turn off the bands they do not want to pass (Uplink & Downlink) all with the click of a mouse. Easily set any alarm trigger point as well as configure and control any parameter of the repeater. Need to narrow the active blocks by just 1 or 2 megahertz to avoid adjacent channel interference? That’s no problem with the Quad Band DR Series from JDTECK. This can be done either locally or remotely via Ethernet or USB using any PC or mobile device. It is hands down the most intuitive and user friendly GUI designed to date.
An Air Sampling feature has been incorporated into the GUI which allows the user to sample the inputs of all the bands and carriers so the appropriate level of attenuation can be added in the GUI even before live transmission. This helps to reduce any macro interference events at commissioning. This feature also doubles as an on-board ‘spectrum analyzer’ letting the user know all the active inputs received at the donor port.
On our Gen 2 version, easily setup your own custom trigger points and receive automated alarm notifications via email which supports both IPv4 and IPv6 protocols with encrypted https communication (or SMS with optional modem) for a host of metrics including: Low RSSI Limits ; Low Output Power Limits | MUTE Shutdown Activated | Signal Oscillation Occurred | Temperature of a Specific Band is Over Limit | One of the Authorized Account Users has Accessed the Repeater (Up to 5 users) | Repeater has Lost AC Power | (On-Board Backup Power for up to 15 mins for management system using Super Capacitors!).
The really neat thing about this product is the ability for the senior RF engineer on staff to be able to remote into the repeater, commission and optimize the DAS from anywhere there is internet. The integration team completes the deployment and with a mobile hot-spot (or if allowed on the customer’s guest network) provide a web connection to the repeater so the highly skilled RF engineer who is an expert at optimization can finely tune the DAS without needing to be physically on site. This process is typically completed in 15 mins. The integration / installation team is then able to walk the entire space to complete benchmark testing, verification and acceptance by the customer.
Each repeater is programmed and bench tested before it ships, which includes a certified test report, so you are assured of strict quality controls and NO dead on arrivals.
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.

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…
