Distributed Antenna Systems

Public Safety / First Responder

COMPLETE TURNKEY SOLUTIONS

The Challenge

In-building wireless communication is essential for everyone who enters any building, facility or venue. In most buildings with concrete structures, and/or underground garages, a public safety amplification system will be needed due to the composition of the building. In a crisis, receiving notifications and connecting with emergency personnel is critical. It is imperative that communication devices continue to work in all areas of a building, such as stairwells, elevators, and basements. This is why the NFPA & IFC set regulations and work with local municipalities to ensure that requirements are in place that will produce dependable and life-saving communications for emergency responders using UHF, VHF, 700 Mhz/800Mhz frequencies. It is acknowledged that the potential lives and property saved by delivering first-responder in-building radio coverage far outweighs the investment required to implement and enforce these ordinances and codes.

Public Safety DAS

The Solution

Due to the building composition challenges, Seamless Cellular offers a Public Safety Distributed Antenna System (DAS) to ensure law enforcement and first responders are provided with an extremely secure way to stay connected with the vital data they need at the time of an emergency. Our systems provide a network of systematically placed antennas connected to coax or fiber-optic cable that delivers guaranteed wireless service within a building or structure. The engineers at Seamless Cellular are iBwave certified and have years of experience designing Public Safety DAS to ensure that they are installed to meet the highest standards.

Public Safety DAS

Key Design Features:

  • Wireless Coverage: 99% in areas of “vital importance”/ 90% in other areas
  • Equipment Enclosures: Housed in NEMA-4 compliant enclosures
  • Minimal Signal Strength: -95 dB is required for adequate coverage
  • Battery Backup: Functions for 24 hours on a battery backup
  • Testing: Long-term system monitoring available

Result

Seamless Cellular will perform grid testing which indicates exactly which areas will need to be covered by the system. Seamless Cellular will then design and install a system based on the exact needs of the buildings to ensure adequate frequency coverage requirements meet the local NFPA and municipality guidelines. These systems are interchangeably referred to as Public Safety “Distributed Antenna Systems” (DAS), Public Safety “Bi-Directional Amplifiers” (BDAs) or Public Safety “Repeaters”.

Long-term Benefits

First responders rely increasingly on radio communication devices, and in emergency situations, they cannot afford signal loss or delays. Seamless Cellular knows that when lives are at stake, every second counts, which is why we make it a priority to design & install high-performance, reliable systems that exceed performance standards. Due to the need to have a reliable means of communication to send and receive information, Public Safety DAS are necessary systems for all types of buildings and properties. Building owners can benefit from improving the DAS infrastructure. Not only does improving the DAS for public safety connectivity make the building a safer place should an emergency occur, it can help make the building more reliable to future occupants (and even in future sales)—benefitting business owners financially and competitively in the commercial property market.
