Are you thinking about using satellite LMR (Land Mobile Radio) for your communication needs? Satellite LMR allows you to use satellites to provide wireless communications similar to walkie-talkies over a wider area. It offers some neat benefits, but also has some downsides to consider. In this post, we’ll walk through the key pros and cons of satellite LMR to help you determine if it’s the right fit for your situation. Let’s dive in!
The Benefits of Wide Area Coverage
One of the best things about satellite LMR is that it gives you extremely wide area voice and data coverage by leveraging satellites in space. You can communicate with team members spread across states, countries, or even continents using handheld satellite LMR radios. This makes satellite LMR ideal for teams that need constant communication in remote areas where traditional cellular networks don’t reach. The global coverage allows unprecedented mobility and connectivity.
Reliability and Redundancy
Satellite LMR provides reliable connectivity even when land-based infrastructure gets damaged. The satellite network acts as a backup option if cell towers or repeaters go down in a disaster. Satellite LMR also allows you to have redundancy built into your communication network – if the satellite connection gets interrupted for any reason, the radios can automatically failover to a terrestrial network. This gives you peace of mind knowing your critical communications are resilient.
Data Capabilities
In addition to voice calls, satellite LMR also enables you to send and receive data messages, GPS coordinates, and telemetry information. This allows you to not only talk with your team members, but also track locations and assets in real-time. Many satellite LMR solutions even integrate with mapping and workflow management software to enhance coordination capabilities. The data connectivity opens up many useful applications.
Hardware Limitations
Now let’s look at some of the downsides. One drawback of satellite LMR is the bulkier hardware. The satellite radios are typically larger and heavier than traditional LMR handhelds. The antenna and extended battery add some heft. This can make constantly carrying and using the satellite radios challenging for some users. Many providers are working on miniaturizing the devices, but for now it’s something to keep in mind.
Higher Latency
Due to the satellite transmission, there is higher latency with satellite LMR compared to terrestrial networks. This means there is a slight lag or delay in the signal. Most providers have latency in the range of 0.5 to 1.5 seconds. This delay may cause some challenges and disjointed conversations for users that are used to real-time terrestrial communications. Proper training can help adjust for the latency factor.
Cost Considerations
Not surprisingly, operating satellite LMR is more costly than traditional LMR solutions due to the satellite airtime fees. The service costs vary by provider and number of users, but are typically priced as a monthly fee per radio. There are also costs associated with the hardware and installation. Make sure to analyze the total long term costs against your budget. That said, many organizations find the benefits outweigh the higher costs.

Regulatory Restrictions
Because satellite LMR utilizes satellites and radio spectrum, there are regulatory restrictions enforced by government agencies like the FCC. The providers handle the licensing, but it’s something to keep in mind – you may need to request permission or qualify for certain usage types. The regulations also mean satellite LMR is not allowed in certain countries, so visibility on geographical coverage is important.
At the end of the day, satellite LMR offers some unique advantages along with some distinct limitations to consider. If you need reliable communication across very wide geographical areas or in disaster response scenarios, satellite LMR may be a great fit despite higher costs and hardware restrictions. For localized communications, terrestrial LMR may make more sense. Assess your specific needs and environment carefully before deciding! With the right diligence, satellite LMR, used with a p25 radio network can be an effective communication solution for many organizations.
