MT-4E Series Radio Systems
The MT-4E Series is Codan’s trusted cornerstone LMR infrastructure platform, delivering industry leading reliability, flexibility and performance. These radio systems can be found at thousands of radio sites working as standalone repeaters/base stations, or operating as a whole network of communications infrastructure, providing coverage in the most challenging terrains. From freezing mountain peaks to scorching deserts, from snowstorms to wildfires, the MT-4E Series has time and again pushed the limits of what radio communications infrastructure can do under extreme conditions, ensuring problem-free operation when it counts.
The modular design of the MT-4E Series allows the product to be configured and customised into almost any conventional radio configuration or architecture, which provides a variety of creative solutions to communication challenges, whether they be simple or complex. Codan's commitment to standards-based, vendor-neutral operation means that you will never be locked into functionality-limiting or costly single vendor solutions.
The MT-4E Series is based on a 19 inch subrack platform consisting of a signal routing motherboard and 3RU rack mounting chassis. Hot-swap capable RF modules (available in UHF, VHF, 700/800/9000 MHz bands, and available in analogue or P25 operation) and control modules are arranged in the subrack housing to create a multitude of different repeater and base station system configurations to suit any communications need. Control modules are added to an MT-4E system to provide various additional functionality, including flexible external interfaces into an MT-4E system including RoIP via the APCO P25 DFSI open standard, paging controller, and 2/4-Wire E&M; signal routing and steering to create any combination of drop-link, multilink or crossband system; and external discipline of the transmitter for increased stability or for modulation of digital paging signals. A selection of amplifier products can also be added to increase the built-in 8 W exciter power from 30 W up to 100 W, depending on application power and rack spacing requirements. The subrack chassis has an optional wrap-around panel with a built-in AC/DC power supply and provides a terminal block that gives access to pertinent audio and control signalling for interface into external controllers, and an optional 1U remote site monitoring option provides live site data and logging capabilities for predictive trending and alarm/trigger notification.
Typical fixed applications include:
The flexible nature of the MT-4E platform allows for simple integration with external controllers, expanding its fixed applications further:
The durable, low current benefits of the MT-4E Series also provides the foundation for transportable products that address a variety of applications, from harsh environments, to tactical deployments. Unlike many products available in the LMR industry, the Codan MT-4E based transportable solutions are among the only offerings that use infrastructure-grade equipment; this means greater reliability and broader functionality, particularly in P25 digital applications.
