Digital Handset Radios Long Range Voice Communication
Introduction
Ad-Hoc Network Radio
The T4 uses wireless MANET(Mobile Ad Hoc Network) technology that provides narrowband self-grouping multi-hop links to achieve a wide area of mesh coverage with digital voice and high security.
In various industries and sectors where the utility for the T4 MANET radio and IWAVE manet radio base stations are highly considered to be used for emergency resuce and disaster response in place with no infrastructure or no network access.
Features

Application
In various industries and sectors where the utility for the T4 MANET radio is highly considered to be used for Create expanded coverage areas with no infrastructure or no network access with the mesh jump function.
With the mesh jump function for medium and wide coverage networks, uses can add the quantity of nodes to extend the network to any place required. Each radios can be freely edited in group call or single call mode that allows you to define the retransmission conditions on the device according to the needs.
