Satellite Comms
What are satellite phones and satellite two way radios?
- Satellite phones and satellite two way radios are communication devices that connect directly to orbiting satellite networks rather than terrestrial mobile or radio infrastructure.
- They are used to provide voice, data, or push-to-talk communication in locations where cellular coverage, fibre networks, or conventional radio systems are unavailable or unreliable.
Scope and Function
- Satellite communication devices enable point-to-point or group communication across regional or global distances. Unlike land-based systems, connectivity is maintained via satellite constellations, allowing operation in remote, maritime, airborne, or disaster-affected environments.
- These devices are commonly deployed where:
- Infrastructure is absent, damaged, or intentionally avoided
- Coverage continuity is required across wide geographic areas
- Communications must remain available during emergencies or system failures

Security and Data Protection.
- Security in satellite phones and satellite two way radios is achieved through a combination of network-level and device-level controls. Depending on the platform and network used, this may include:
- Encrypted air interfaces between the device and satellite
- Authentication of devices on the satellite network
- Secure routing through controlled ground stations
- Optional end-to-end encryption implemented at the application or device layer
- The specific encryption standards and security guarantees depend on the satellite network, device model, and configuration.
Applicability and Use Cases.
- Satellite phones and satellite PTT radios are used across sectors where reliable long-range communication is operationally critical, including:
- Emergency response and search and rescue
- Remote industrial operations
- Maritime and offshore environments
- Government and public sector field operations
- Scientific, exploration, and expedition activities
- They are typically selected when coverage predictability and independence from local infrastructure are higher priorities than bandwidth or consumer-grade features.
Explore our satellite phone and two way radio portfolio.
- The product range on this page includes two primary device categories:
- Satellite phones, designed for one-to-one voice calls, messaging, and basic data services over satellite networks
- Satellite push-to-talk radios, designed for group communications using dispatch-style PTT functionality over satellite links
- Each device operates on a specific satellite network and supports different coverage regions, service plans, and performance characteristics.

Product selection criteria.
- When selecting a satellite phone or satellite two way radio, key technical and operational factors include:
- Voice versus push-to-talk communication requirements
- Battery life and standby performance
- Environmental ratings and physical durability
- Integration with existing radio or communication systems
- Security features supported by the device and network
- Device choice is typically driven by mission profile, operating region, and interoperability requirements rather than brand or form factor.
