CriticalPoint™ Public Safety UHF Class A/B DAS

System Design and Capabilities

• Master Unit and Expansion Potential: At the heart of the CriticalPoint UHF DAS is the Master Unit (MU), robust enough to function independently as a Bi-Directional Amplifier (BDA) covering up to 350,000 square feet. This MU can be integrated with up to three Fiber Expansion Units (FOUs), extending its reach to support up to 32 Remote Units (RUs), which can ultimately cover millions of square feet to supply wireless signals for first responders. This extensive coverage capacity makes it an ideal solution for very large buildings or complex campus environments where first responders require seamless communication across multiple locations.
• Flexible Filtering Options: The system supports a range of filtering options with up to 32 narrow-band filters for Class A or up to four wide-band filters for Class B, accommodating internal one-, two-, or three-window filtering. This flexibility allows the system to be tailored to specific public safety needs and frequencies, ensuring clear and reliable communications.

Enhanced Communication Features

• Channelized Control for Quality Assurance: The CriticalPoint system includes channelized uplink squelch and Auto Level Control (ALC) features, which help minimize interference with base stations and optimize the quality of communications. These intelligent configurations are crucial for maintaining clear channels during critical operations, avoiding any potential disruptions that could affect response effectiveness.
• Comprehensive Monitoring and Alarming Capabilities: Fully compliant with both the International Fire Code (IFC) and National Fire Protection Association (NFPA) standards, the CriticalPoint UHF DAS includes extensive alarming capabilities. It supports all required monitoring and alarming protocols and provides options for both local and SNMP-based remote monitoring. These features ensure that any issues can be immediately identified and addressed, maintaining system integrity at all times.

Efficiency and Design

• High-Efficiency Amplifier Design: Utilizing Comba’s renowned high-efficiency amplifier design, the CriticalPoint UHF DAS not only offers a compact and lightweight setup but also operates with lower electrical and battery backup costs. The NEMA 4-compliant enclosure ensures that the system is protected against environmental factors, contributing to its durability and long-term reliability.
• In-House Design and Manufacturing Excellence: Comba’s vertical integration in the design and manufacturing processes allows for stringent quality control and cost efficiency. This integration ensures that the CriticalPoint UHF DAS remains affordable without compromising performance or reliability.
