Scalable Wireless Solutions
Modern facilities require wireless infrastructure that is not only powerful but also adaptable. The increasing density of wireless services, ranging from public safety communications to commercial cellular and 5G, requires a Distributed Antenna System (DAS) that can handle diverse frequency bands and evolving technologies. A one-size-fits-all approach is no longer sufficient for complex venues like airports, hospitals, and large corporate campuses. Through our strategic partnership with Comba Telecom, MCA delivers the ComFlex 600 Series DAS, a comprehensive portfolio of RF-over-fiber solutions. This series is engineered to provide unmatched flexibility and scalability, addressing the full spectrum of in-building wireless coverage challenges.
What is the Comba ComFlex 600 Series?
Quick Definition: The Comba ComFlex 600 Series is a modular Distributed Antenna System (DAS) designed to deliver reliable, multi-band wireless coverage across large or complex facilities.
The Comba ComFlex 600 Series is an advanced, modular Distributed Antenna System designed to enhance wireless network coverage by extending cellular and public safety services from existing cell sites into any indoor or outdoor environment. The series is built on a common platform centered around a modular Master Unit (MU), which integrates RF signal access, optical conversion, and system control into a single, cohesive chassis. This architecture allows for a tailored approach to wireless coverage, supporting a wide range of frequencies, power levels, and deployment scenarios.
The ComFlex 600 Series is not a single product but a family of solutions, including the 6100, 6800, 6900, and 6Q00 models. Each model addresses specific frequency bands and performance requirements, from public safety and enterprise cellular to specialized commercial bands. This modularity ensures that system integrators can design a DAS that precisely matches the needs of any venue, providing a future-ready platform that can grow and adapt over time.
ComFlex Core Architecture and System Benefits
Definition: Each ComFlex 600 system features a unified Master Unit chassis supporting multiple RF and optical modules, ensuring adaptability, performance, and simple maintenance.
The ComFlex 600 Series is built on a foundation of flexibility, reliability, and performance. Its shared architecture ensures a consistent deployment and management experience across all models, while offering features tailored to demanding wireless environments.
- Unified Modular Platform: The series uses a standardized 19-inch rack-mounted Master Unit chassis. This allows for easy field upgrades and maintenance by simply swapping RF and optical modules as needed.
- Scalable by Design: A single Master Unit can support up to eight RF sources and eight Remote Units. For larger venues, a Fiber Optical Extension Rack can be added to double the Remote Unit capacity to sixteen, all managed from a central point.
- Independent Gain Control: Every RF source is managed independently, giving system designers granular control over signal levels. This is critical for balancing multiple carriers and preventing interference in mixed-mode applications.
- Superior RF Performance: The system is engineered for high linearity and features 4.3-10 RF connectors, ensuring superior Passive Intermodulation (PIM) performance and providing clean and clear signal transmission.
- Intelligent Commissioning: A web-based GUI provides a simple and effective interface for both local and remote configuration, commissioning, and monitoring, reducing operational complexity.
- High Reliability: With a high Mean Time Between Failures (MTBF), modular Power Supply Units (PSU), and convection cooling, the ComFlex 600 series is designed for long-term, reliable operation.
A Tour of the ComFlex 600 Series Portfolio
Definition: The ComFlex 600 Series includes multiple models – 6100, 6800, 6900, and 6Q00 – each tailored to different frequencies, power levels, and venue types.
While each model in the ComFlex 600 Series shares the same core architecture, they are distinguished by the frequency bands they support. This allows for the creation of highly customized solutions tailored to specific carrier, enterprise, or public safety requirements.
ComFlex 6100 Series: The Versatile Workhorse
The ComFlex 6100 is the most popular solution in the 600 Series, offering broad support for the most common North American cellular and public safety bands. Its versatility makes it an ideal choice for a wide range of enterprise and public-sector deployments. Due to its extensive feature set and popularity, we have dedicated a separate, detailed article to the ComFlex 6100, which we encourage you to explore for a more in-depth look.
ComFlex 6800 Series: The Public Safety and Enterprise Mainstay
The ComFlex 6800 models are engineered to support the most critical public safety and enterprise cellular frequencies. These systems are designed to provide reliable, high-quality coverage for first responders and commercial users simultaneously.
- Frequency Support: 700MHz (Lower ABC/Upper C), 800MHz (ESMR), 850MHz (Cellular), 1900MHz (PCS), and EAWS bands.
- Remote Unit Options:
- Low/Medium Power (2W/5W): Ideal for indoor enterprise environments, these units are compact, convection-cooled for silent operation, and power-efficient.
- High Power (40W): Housed in a weatherproof IP65 enclosure, these units are designed for large venues or outdoor deployments, providing robust coverage with downlink output power of +46 dBm.
- Application: Ideal for hospitals, corporate campuses, and government buildings that require reliable public safety and commercial cellular coverage.
ComFlex 6900 Series: High-Power, High-Bandwidth Solutions
