1 Introduction
Leaky coaxial cable has both signal transmission and antenna functions. By controlling the opening of the outer conductor, the controlled electromagnetic waveenergy can be uniformly radiated and received along the line, covering the blind area of the electromagnetic field, and achieving the purpose of smooth mobile communication.
2. Packing Details
- Mobile communications in buildings, tunnels and subways (GSM, PCN/ PCS, DECT …)
- Communications in underground buildings, such as parking lots, basements and mines
- Transmission of FM band (88-108MHz) information in highway tunnels
- Forwarding of wireless alarm signals in highway tunnels
- Transmission of mobile phone signals in highway tunnels
- Signal transmission in subways or subway tunnels
