Why Land Mobile Radio Systems are Ideal for Mobile Critical Communications

Land Mobile Radio systems are terrestrially-based push-to-talk wireless communications systems that are often used for critical communications by organizations such as firefighters, police, and various emergency response teams. They are also used by other industries including transportation, utilities, industrial, security, and even military. LMR systems can come in the form of handheld portable radios like the MSAT G2, satellite phones like the iSatPhone Pro 2, network infrastructure, vehicle-mounted mobile radios, and fixed base stations and repeaters.

What are the advantages of LMR systems?


The feature that makes LMR systems best for mobile critical communications is push-to-talk. The user only needs to press a push-to-talk button, speak into the device, and then release the button to put the radio back into receive mode. This ease of use is essential for critical communications. In a high-pressure situation, the user will not have time to look at a phone, use an app or look up a contact, then make a call. It’s imperative that communication happens as quickly and easily as possible.


Disasters can hinder or even disable communication systems completely when it knocks down phone lines and cellular systems. LMR systems have the best coverage of any wireless communications technology. In the event of a disaster, when most conventional communication systems are disabled or overloaded, dispatch satellite radio and voice services is a reliable crisis communication alternative. Its coverage is further extended using a network of high-power towers and radio systems covering cities, states, and even countries.

What should you look for in an LMR system?

Open Platform

LMR technology that operates on open standards provides greater flexibility, lower prices, as well as more options and features to choose from. This system is developed by international accredited standardized organizations such as the Telecommunications Industry Association (TIA). Closed platforms can be quite difficult to navigate for organizations. They also cost more and have fewer features. When a manufacturer stops supporting closed platform technology, you will have to buy a new system. Open platforms have multiple suppliers that support its technology, so you can transition to a new company easily without the need to buy new equipment.


The LMR system you choose should have a software-defined platform. Instead of having to buy multiple add-on features and boxes to support your needs, opt to buy one box that gives you the flexibility to switch between FM, P25, or DMR technologies when you change the software.

Reliability and resiliency

Your LMR system should be reliable and incredibly resilient. Disasters and emergency-critical events require you to have a system that has good coverage, good audio quality, and steady communication. Make sure your system has failover, which means that if one part of its system fails, backup equipment can automatically take over. Make sure you acquire your LMR system from a reputable and experienced vendor. You’ll also need to ensure that you work with a knowledgeable supplier who can help you find the appropriate system for your needs.

Land Mobile Radio systems are incredibly easy to use, robust, and affordable. They are the safest and most reliable choice for critical communications.
