Distributed Antenna Systems DAS
A Distributed Antenna System (DAS) distributes radio frequency (RF) signals within a building, typically through fibre, coaxial cable, and a series of antennas.
The two most common signals carried over DAS deployments are for cellular (e.g. 4G LTE and 5G) and public safety radio transmissions. Cellular DAS deployments typically utilise a small cell or a BTS signal source, while public safety DAS systems most often use a rooftop antenna to connect back to the local emergency radio system.
The implementation of safety codes such as National Fire Protection Association (NFPA) and the International Code Council (ICC) in buildings made mandatory by governments has been a major driver for the uptake of public safety in-building wireless Distributed Antenna Systems (DAS) across the globe.
Other drivers include:
- growth in the need for consistent and reliable public safety networks,
- the growing trend towards smart cities and buildings,
- an increase in the number of accidents in building premises,
- the need for uninterrupted mobile communication.
The DAS headend and remote unit system component is expected to have the largest market share in the public safety in-building wireless DAS system market in the period to 2025. This is because of its high-end performance and discrete carrier access control. DAS headend and remote unit is now being modified to make it compatible with public safety communication spectrum, by eradicating traditional techniques. Direct digital interface with simplified deployment capability enables it to have the largest market share.
North America is expected to have the largest market share in the public safety in-building wireless DAS system market from 2016 to 2021, due to government public safety requirements and the increasing amount of public infrastructure. Asia-Pacific offers potential growth in this market due to an increase in the number of in-building wireless communication deployments for smart cities and buildings.
The major vendors in the public safety in-building wireless DAS system market are SOLiD, ADRF, Commscope, Ericsson, Anixter Inc., Cobham PLC, and Corning.
