The standard is sufficiently detailed and open that there are currently different terminal manufacturers on the market whose equipment can interoperate in networks of different infrastructures. <\/p>\n<p>The possibility of <strong>complete interoperability between products from different manufacturers is a differential advantage<\/strong> of the open standards developed by ETSI. The TETRA standard is <strong>supported by various independent manufacturers<\/strong>, which encourages competitiveness by providing the user with a second source for product selection. <\/p>\n<p>TETRA is currently used worldwide, providing <strong>security, reliability, and robustness<\/strong> in critical communications.<\/p>\n<p>The <strong>TETRA Association was created in December 1994<\/strong> as an independent association, and today it includes more than 150 organizations worldwide (see <a href=\"http:\/\/www.tetramou.com\">www.tetramou.com<\/a>).<\/p>\n<h2>TETRA Systems in Remote Control<\/h2>\n<p>TETRA is a narrowband private network whose <strong>use in remote control applications is increasingly common<\/strong> as it provides certain advantages such as network reliability and availability, and the possibility of using existing infrastructures at a low cost, even with coverage in areas not normally covered by other public networks. Often, remote facility management systems do not require high speed and bandwidth, but high availability and reliability, and in these areas TETRA guarantees the service (let&#8217;s not forget that it is a network originally created for emergency systems, firefighters, police, ambulances, etc.). <\/p>\n<p>The data communication protocols that use the TETRA medium must be prepared for this. <strong>The DNP3 telemetry protocol is very suitable for use in TETRA networks<\/strong> (due to the advantages we have seen in the previous chapter). Given the limitations in bandwidth and speed of this network, the implementation of an inadequate communications strategy (use of industrial protocols or those based exclusively on \u201cpull\u201d) can lead to undesirable results in the project. <\/p>\n<p>There are <strong>TETRA routers oriented to remote control and M2M communication<\/strong> specifically designed for this purpose on the market. These are data terminals that support the transmission of industrial protocols <strong>(DNP3, Modbus, IEC60870, etc\u2026)<\/strong> in a transparent way, without the need to use AT commands from the control station. In addition, they have transmission optimization mechanisms such as the use of compression algorithms to better exploit the limited bandwidth of TETRA networks, as well as routing tables for sending IP packets to different remote equipment.  <\/p>\n<h2>TETRA SDS Communications<\/h2>\n<p>Through the TETRA SDS protocol, it is possible to send serial messages using the control channel. Communications are slower but are not interrupted by voice. <\/p>\n<p><a href=\"https:\/\/becolve.com\/wp-content\/uploads\/2023\/04\/red-tetra-SDS.png\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1754 aligncenter\" src=\"https:\/\/becolve.com\/wp-content\/uploads\/2023\/04\/red-tetra-SDS.png\" alt=\"TETRA SDS network\" width=\"630\" height=\"344\"><\/a><\/p>\n<p style=\"text-align: center;\">            <em>TETRA SDS Network through a switch<\/em><\/p>\n<h2>TETRA Packet Data Communications<\/h2>\n<p>Data transmission in TETRA via Packet Data allows us a fast transfer of IP data.
