In-building public safety wireless solutions

CommScope offers multiple public safety solutions that economically scale according to the size of the building being covered, its the public safety requirements.

As public safety signal source, the software-defined Public Safety Bi-directional Amplifier (BDA) is a platform that enables tailored, scalable and cost-efficient implementations of Class-A and Class-B public safety bi-directional amplifiers. Frequency bands and features can be configured in software to adapt to the specific project needs. The Public Safety Bi-directional Amplifier has been designed for public safety from the ground up:

• 700MHz and 800MHz frequency bands in a single chassis with fully integrated multi-band combiner
• Software-based platform enables on-the-fly filter changes
• Available in .5 watt and 2 watt power classes to cover a wide range of facility footprints while optimizing total system cost
• Uplink muting for unused narrow-band channels in order to avoid uplink desensitization of BTS receivers
• Remote alarming through SNMP interface
• Rated for both indoor and outdoor placement
• NEMA 4x with wall mount, or pole mounting options
• Automatic gain control to prevent oscillation under insufficient isolation conditions
• Battery backup (using external backup unit)

For small and medium-size buildings, typically up to 100,000-250,000 square feet, the Public Safety BDA and donor antenna is connected directly to a set of output antennas placed throughout the building. CommScope provides a full range of indoor antennas and related passive components designed to support public safety frequencies.

In smaller buildings, the Public Safety Bi-directional Amplifier directly feeds several in-building antennas.

For larger buildings and multi-building campuses, the Public Safety Bi-directional Amplifier is a signal source to CommScope’s ERA digital distributed antenna system, provisioned as a public safety DAS. As an active, digital DAS, ERA ensures the distribution of public safety RF signals throughout buildings and campuses of any size. ERA currently provides public safety and commercial services in venues ranging from office buildings up to NFL stadiums and major airports. ERA offers features created specifically for public safety needs:

• CAP-M remote provides 1 watt (30 dBm) of transmit power making it ideal for large indoor spaces like warehouses, factories, airports, metro stations, stadiums, performance centers and large office buildings. It supports 400MHz, 700MHz and 800MHz public safety bands including support for FirstNet.
• UAP-X remote provides lower power of 60 mW (18 dBm) for smaller spaces. It supports any band (software-selectable) from 380 to 2700 MHz and uses internal antennas for space savings and office interior aesthetics
• Enclosures – CommScope provides fully NEMA 4x-compliant enclosures for head-end elements and remotes.
• The A.I.M.O.S. operation and maintenance system allows real-time local and remote monitoring and management of public safety systems to ensure full network operability and uptime.

CommScope also provides a range of passive products and cabling for a complete public safety network solution.

• Antennas and passive products - indoor antennas and related passive components designed to support public safety frequencies
• SYSTIMAX® and NETCONNECT® structured cabling solutions providing coaxial, fiber and twisted-pair cabling that complies with local and regional fire safety regulations, including LSZH (low smoke zero halogen) cables.
• Construction Product Regulation (CPR)—classified cables including HELIAX® 50-ohm coaxial cables in multiple fire safety design options.

In larger buildings and campuses, the Public Safety Bi-directional Amplifier feeds an ERA digital DAS which can distribute the signal across an extremely wide area such as a stadium complex, airport or university campus.
