ADRF SDRC Series: Part 20 Modular Repeater System with Professional Performance
Small to mid-sized facilities face unique connectivity challenges that traditional carrier-grade solutions often cannot address cost-effectively. Offices, warehouses, apartments, and retail environments frequently experience cellular dead zones that disrupt productivity, compromise safety communications, and diminish customer satisfaction. These facilities need reliable in-building coverage solutions that balance professional-grade performance with consumer-friendly deployment and maintenance requirements.
MCA’s partnership with Advanced RF Technologies enables us to deliver the ADRF SDRC Series, an innovative approach to addressing these coverage gaps through consumer-grade accessibility combined with carrier-grade reliability.
What is the ADRF SDRC Series?
The ADRF SDRC Series represents ADRF’s first Part 20-certified consumer-grade repeater, engineered to deliver superior performance and reliability for small to medium-sized venues. This modular signal booster system combines advanced digital signal processing with simplified deployment procedures, making professional-grade cellular enhancement accessible to facilities that previously could not justify the cost or complexity of traditional distributed antenna systems.
The SDRC platform supports quad-band service within a single chassis, delivering simultaneous coverage across 700 MHz, Cellular (850 MHz), PCS (1900 MHz), and AWS (1700/2100 MHz) frequency bands. With a maximum downlink output power of 17 dBm per module, the system provides robust signal enhancement while maintaining compliance with FCC Part 20 consumer booster regulations.
Advanced Digital Signal Processing Architecture
The SDRC Series incorporates sophisticated digital filtering technology typically reserved for carrier-grade infrastructure equipment. This advanced signal processing capability distinguishes the platform from conventional consumer boosters while ensuring reliable performance in complex RF environments.
Channelized Digital Filtering
The system employs up to three channelized digital filters with sharp roll-off characteristics that effectively reject adjacent carrier interference. This precision filtering enables clean signal amplification even in congested spectrum environments where multiple carriers operate in proximity.
Key Filtering Capabilities:
- Sharp roll-off digital filtering minimizes interference from adjacent frequency bands
- Band equalization ensures balanced signal strength distribution across all supported frequencies
- Automatic Level Control (ALC) maintains optimal signal levels without oversaturation
- Digital signal processing eliminates traditional analog filter limitations
Intelligent Safety Systems
The SDRC platform integrates multiple safety mechanisms that protect both the booster system and the broader cellular network infrastructure:
- Oscillation Detection and Prevention: Advanced algorithms continuously monitor signal paths to detect potential oscillation conditions, automatically implementing shutdown procedures when necessary to prevent network interference.
- Overload Protection: Integrated overload shutdown features safeguard system components from excessive input signals while preventing downstream interference.
- Network Monitoring: Real-time performance monitoring ensures optimal operation while providing immediate notification of conditions requiring attention.
Modular System Architecture
The SDRC Series leverages a flexible modular design that enables customized configurations tailored to specific facility requirements while providing scalability for future expansion.
Repeater Module Portfolio
The core of the SDRC system consists of hot-swappable repeater modules designed for specific frequency bands:
- SDRC-17-7F (700 MHz Module): Supports FirstNet Band 14 and commercial 700 MHz LTE services, providing essential low-band coverage for extended range and building penetration.
- SDRC-17-C (Cellular Module): Delivers traditional cellular (850 MHz) coverage for voice and data services, ensuring compatibility with legacy networks while supporting LTE enhancements.
- SDRC-17-P (PCS Module): Covers PCS 1900 MHz frequencies widely used for high-capacity LTE services, particularly effective in dense user environments.
- SDRC-17-A (AWS Module): Supports AWS 1700/2100 MHz bands extensively deployed for both LTE and 5G services, providing future-ready connectivity enhancement.
Each module delivers 17 dBm maximum downlink output power with 4.3-10 Female donor and server ports, plus SMBL Female ports for downlink output and uplink input connectivity.
