OVERLANDING COMMUNICATIONS 101: RADIOS EXPLAINED

OVERLANDING COMMUNICATIONS 101: RADIOS EXPLAINED

by Sibtain Azhar

Effective communication is one of the most critical components of any overland adventure or trail run. Whether you're coordinating with a convoy or facing an emergency in a remote location, having the right overlanding communication devices can make all the difference. 

At STARS Overland, we believe in a multi-layered communication strategy—using a combination of cell phones, radios, satellite phones, and satellite messaging devices like the Garmin inReach. Not every trip requires all of these tools, but understanding your options will help you choose the best setup for your needs. 

Basic Communication: Cell Phones 

A cell phone is the most accessible communication tool and works well in areas with coverage. However, once you're off-grid or in mountainous terrain, you'll need more reliable options. 

Trail Communication: CB, FRS, and GMRS Radios 

CB Radios 

  • License Required: Check countries’ regulations 

  • Best for: Short-distance communication (under 1 mile / 1.6 km) 

  • Limitations: Limited range, outdated technology 

  • Use Case: Quick trail runs with vehicles in close proximity 

GMRS (General Mobile Radio Service) Radios 

  • License Required: Check countries’ regulations 

  • Range: Up to 5 watts on handhelds, more on mobile units 

  • Best for: Convoy communication, GPS location sharing (up to 5 miles / 8 km) 

  • Top Picks: Garmin Rino (voice + location sharing), Rugged Radios 45-Watt GMRS Kit 

GMRS radios offer better range and clarity than CB or FRS, making them ideal for off-road communication. Installation is similar to CB radios but with significantly better performance. 

Advanced Communication: Ham Radios 

If you're ready to take your communication to the next level, Ham radios offer unmatched range and functionality. 

  • License Required: Check countries’ regulations 

  • Range: Up to hundreds of miles via repeaters 

  • Capabilities: Voice, telemetry, GPS coordinates, speed, altitude 

  • Best Use: Remote expeditions, aerial-ground coordination (up to 2 miles / 3 km) 

  • Recommended Model: Icom ID-5100 

Ham radios are ideal for serious overlanders who need long-range communication and data transmission. They’re especially useful when traveling in areas with repeater networks. 

Satellite Communication Devices 

For true off-grid emergency communication, satellite devices like the Garmin inReach are essential. These tools allow you to: 

  • Send and receive messages 

  • Share GPS location 

  • Trigger SOS alerts 

They’re lightweight, reliable, and perfect for solo travellers or remote expeditions. 

Starlink Internet 

For those who need internet access in remote locations, Starlink satellite internet is revolutionizing how overlanders stay connected. With high-speed, low-latency service available almost anywhere with a clear view of the sky, Starlink enables real-time communication, remote work, weather monitoring, and emergency contact—even in the most isolated regions. 


Whether you're uploading content from the trail, managing logistics, or staying in touch with loved ones, Starlink for overlanding adds a powerful layer of connectivity that complements traditional radio systems. Its portability and ease of setup make it a top choice for full-time travellers, digital nomads, and expedition crews. 

Note however that Starlink is currently only available in 130 countries and territories, and it is advisable to check the countries’ regulations that you are planning to cross during your overlanding trip.
