CSE Chatterbox designs innovative two-way radio solutions. Working in partnership with the world’s leading technology suppliers we can select from a wide range of hardware and software to engineer the best system to suit each client’s requirements, providing systems based on one of four key technologies:

• CSE Chatterbox CALM and CALM+ digital mobile radio (DMR) systems can interface with other voice and data systems, providing a raft of sophisticated features designed to protect the health and safety of your employees and members of the public and improve communication and operational efficiency.
• We can design PTToC (Push to talk over cellular) systems that combine the benefits of two-way radio (one to many communication) with the coverage of a mobile phone.
• CSE Chatterbox CALM IP RoIP two-way radio systems provide clients with cost-effective two-way radio coverage using their existing Wi-Fi network and do not require a two-way radio licence.
• CSE Chatterbox CALM TETRA uses TETRA (Terrestrial Trunked Radio) technology which is the most robust technology available for commercial radio systems having been developed specifically for government agencies and the emergency services i.e. mission critical communications.
