How does Satellite PTT Radio provide independent communications?
Satellite PTT Radio devices are connected via satellites in space which allow them to reach beyond the limitations of an antenna-based infrastructure – for day to day communications in a remote location or during a critical incident rather than relying on ground-based infrastructure for connectivity, you are always connected, even when traditional methods fail.
Organisations that require critical long-range communication capabilities such as emergency services (disaster response, first responders), non-governmental organisations (coast guard, research teams) and businesses & organisations (mining, oil refinery, nuclear facility, shipping) have all benefited from this technology.
How do Iridium satellites work?
The Iridium Satellite covers Earth with 75 satellites (66 operational and 9 in-orbit spares), these low earth orbit (LEO) satellites cover 100% of the planet. Unlike geosynchronous equatorial orbit (GEO) satellites, Iridium satellites are 46 times closer to the earth, enabling superior coverage and service.
What features do Satellite PTT Radios offer?
Satellite communications connect you to the outside world from anywhere in the world, whether you are inside or outside of radio/cellular coverage, providing highly reliable, cost-effective equipment.
Enhancing your existing infrastructure
As with all radio communication technologies, satellite systems have their strengths and weaknesses, and therefore they are often used in conjunction with other technologies to ensure communications are not interrupted. For example, the ICOM SAT 100 and IC-SAT100M Satellite PTT Mobile Radio offers interoperability with existing two way radio networks (using VE-PG4) in addition to:
- End-to-end AES-256 encryption
- Emergency call function
- Waterproof, dust-tight & durable body (IP67) with unique AquaQuake™ function
- 1500 mW powerful audio
- Multiple language display (English, Chinese, French, Japanese, and Spanish)
- Voice recording functionality
- Short data messaging facility for iOS™/Android™ devices
Whilst its weather-resistant L-band spectrum signal ensures connectivity in the harshest conditions.
Emergency preparedness and disaster recovery with Satellite Radio
During critical situations organisations need to be prepared to navigate any situation, which is why emergency preparedness should always start with establishing a fail-safe communications system that can handle anything.
Because of its resilient infrastructure, availability and ease of deployment satellite communications have been the foundation of disaster safety systems for decades. Designed to be used either in-buildings or installed into vehicles/vessels, satellite PTT (Push-To-Talk) can be used to establish communication even in remotest of areas without access to landlines or mobile phones. For example, operating exclusively on the Iridium® satellite network the ICOM IC-SAT100 PTT radio can provide a stable back-up, independent of terrestrial networks in the event of a natural or man-made disaster, improving situational awareness and worker safety.
Quick Satellite communications Q & A
- What about communication fees? Communication fees are typically charged at a flat rate through a monthly plan, and there are no additional call charges.**
- What is a “Talkgroup”? Using SATELLITE PTT, you can communicate with other IC-SAT100/M radios assigned to the same Talkgroup. The coverage area of the Talkgroup is selectable from five sizes (see the table above).
- How do I assign a coverage area? Coverage areas can be split into different regions, using circles, squares and rectangles. For example, you can assign coverage areas to Tokyo, New York and London.
*Depending on the country or area, a flat charge plan may not apply, or the service may not be available.
**Communication fees differ, depending on the coverage area and the number of the IC-SAT100/M satellite ptt radios.
