A Cellular Distributed Antenna System (DAS) is a network of antennas strategically placed throughout a building, venue, or area to enhance and distribute cellular signals. The purpose of a Cellular DAS is to improve the coverage and capacity of wireless communication networks, ensuring a strong and reliable signal for mobile devices within a specified area. Active DAS consists of three-stage system, that is:
Applications :
- Airports
- Road tunnels
- Railway tunnels
- Subway and tramway tunnels
- Shopping malls
- Hotels
- Convention centres
- Hospitals etc.
Point of Interface (POI):
- Supports Wideband frequency from 700 to 3800 MHz as one product.
