TETRA Base Station – Outdoor

BS421 outdoor TETRA base station:

 

Overview

• Easy to install – anywhere : Direct mounting on antenna masts, buildings and towers.
• Easy integration – open API : Unlimited integration into customized applications and existing system.
• Energy efficient : Reduce OPEX with low base station power consumption.
• Flexible and scalable : 100% IP-based technology provides full architectural network flexibility.

• IP65-encapsulated TETRA base station: The BS421 outdoor base station is a mast-mountable and compact IP65-encapsulated TETRA communication system. This advanced and powerful base station transceiver and distributed controller is ideal for outdoor mounting because of its compact size and its rugged design. Additionally, it is equally well suited for indoor use.
