Tetra & DMR Radio

Tetra Radio communication

Tetra which stands for Terrestrial Trunked Radio is an open standard for land mobile radio communication and it is more useful for having secured and quality communication in mission-critical and operation critical projects. Depending upon the usage and area of coverage Tetra radio communication may be handheld, portable, and vehicle-mounted and it can be also fixed-base devices Tetra radio communication is the most often used way of communication for so many years. It is been said that Tetra radio communication is much more reliable and predictable and has less interference with the high bandwidth. And boosting of an existing signal is been done in a very impressive manner between each of the corresponding radiofrequency. Radio communication can do its work where cell phone fails to do the task. Radio communication is faster to share information and also we can feel secured to share any kind of information through Tetra radio communication. Radio communication is more useful to police and another kind of workers were sharing information need to be put under the all channels and should the communication is done should be so secured and legit. AARMTech provides you the Flexible, Scalable, and Reliable user-friendly Tetra radio communication. We take the lead through superior engineering and constant focus on the actual need of the customer by reducing the complexity. Our experts have a wide knowledge and expertise in radio communication, who exactly knows what it takes to run a system smoothly. Before implementing the project we do conduct a radio coverage study to demonstrate the site coverage performance by providing received signal coverage plots. The Radio coverage stimulation is done by using the Pathloss coverage prediction software which requires the input of certain parameters of your workplace such as to receive signal level, site information equipment, environmental parameters, and elevation data. AARMTech will also conduct site surveys to make actual signal strength measurements to achieve the maximum possible accuracy that meets all your communication needs.

Key benefits of Tetra radio communication.
  • Flexible and comprehensive
  • Fast, robust, and highly secured
  • Enables high-quality communication between users
  • Interoperable
  • Multi-vendor support
  • High efficiency and more reliable


Tetra radio communication is a very secure and reliable radio communication for the use of Tetra radio communication Employees must be able to communicate with the other colleagues in the field through secured communication like Tetra radio communication. AARMTech has the secured and modern solution for tetra radio communication for the professionals to meet their requirements through radio communication. Tetra radio communication provides you the excellent radio coverage without the black spot and Tetra radio communication is more efficient and easy for the users. In this modern Era, Tetra radio communication is very necessary for any kind of developed profession to meet their trusted communication needs. Communication between employees and represented authority is an important factor to be considered, so Tetra radio Communication becomes an option to meet the radio communication needs. AARMTech has a comprehensive range of solutions and services provided for radio communication. AARMTech has a good vendor relationship with the world’s top Radio communication brands like Motorola, Kenwood, Roxon, Icom, Yeasu, Hytera, and many more. The main benefits of Tetra radio communication are its area of coverage, the capacity of the system which can be used to address the peak usage, no additional cost for the airtime and price of the tetra radio solution can be predictable, you can choose where you want to configure tetra radio and you can have a high degree of control over the design and implementation of the radio communication.

DMR Radio communication

Digital mobile radio (DMR) is defined as two-way communication. DMR Radio is one for the communication platform which delivers beneficial communication between the employees in mission-critical projects. The main aim of DMR radio communication is to have a digital radio system with low complexity and to make it available on a low budget that still allows getting connected to the employees working in different locations. DMR radio (digital mobile radio) technology can be utilized to gain a proper imperfection in a digital system with low complexity. We have also maintained a good standard in the DMR radio solution which is designed with the three tiers of interoperability across the band. Our DMR radio has many features which is been well developed and capable of introducing proprietary features which help us to maintain the standard of our DMR radio solution. DMR radios standard is capable of working within the 12.5 kHz channel spacing which is been utilized in the land mobile frequency bands all over the world. DMR radios are the best option which has a very good coverage range to the analog FM.DMR radios are published all over the world in digital radio standard which is been specified with the 2 slots of the channel and it has a standard, which is mainly utilized to replace the aging analog standard with doubling the existing capacity of the current channel.

In most cases, Radio communication is used in mission-critical projects to have secure communication with a long-range of coverage. DMR radio allows ease of integration with all network components, it can be integrated into the radar and camera surveillance system or various independent systems. Digital data communication can be realized with radio links, cable, or via satellite. AARMTech radio communications solutions are fully scalable with no limitation and allow the system to be extended with an unrestricted number of transceivers, transceiver site, operator, or operator site. The IP-based architecture supports users with various right and multiuser scenarios which priorities the amount that are instantly configurable consistent with the need. Various features of radio communication make DMR radio communication a more reliable way of communication like open architecture, continuous monitoring, early warnings for hardware malfunction, remote access for maintenance.

DMR radio has been divided accordingly to the usage into three tiers. And utilization of it depends upon the purpose of the usage. DMR radio tier 1 can be utilized in 446MHZ and it is unlicensed and can be used as a direct mode like radio to radio. DMR tier 1 can be used for the small organization which works on a local basis. The product therefore used for personal use. DMR radio tier 2 is a conventional radio type for mobile and hand portable devices where an individual group of people is supposed to allocate the radio channel. DMR radio tier 2 requires a PMR license where its frequency Is ranging between 66MHZ to 960 MHZ. Tier 2 is of having a wide range which can be increased with the help of base stations. The voice feature obtained for tier 2 is advanced and by two slot time division multiple access (TDMA) we can integrate the IP data. DMR radio tiers function is almost the same as tier 2 but it had an option of digital trunking support. DMR radio tier 3 control channel dynamically allocates the radio channel to the number of users as per requirements. The frequency band of DMR radio 3 is the same as the frequency band offered by the DMR radio tier 2 that is between 66MHZ to 960 MHZ. Tier 3 is having a huge range of coverage. Along with the controller simulcast and multicast are required to manage the communication.
