Personal Communication
Anywhere in the World

Communication device which connects to your smartphone, enabling you to use your phone when out of signal of standard networks all around the globe.

Unparalleled connectivity using satellite constellations

IDC worked closely with a leading company in satellite communication to develop this Satellite Phone Case. The device would connect to a global coverage of satellites providing access to voice and data services anywhere on Earth. Connecting people and devices in the world’s most remote places.

The Satellite Phone Case could be used as a hotspot for mobile phones to connect to the satellite network or used independently to contact pre-loaded numbers and make SOS calls in the event that the user's mobile device runs out of battery. The device users geolocation so users have more security that they can be found and rescued in emergency situations.

The Satellite Phone Case was made for adventurers and remote workers, keeping them connected to the rest of the world. The device would have military, search and rescue, aviation and nautical purposes, all of which have specific design requirements.

The device was designed to be rugged and durable to withstand the harshest conditions. It achieved an IP68 rating making it dust resistant and able to withstand submersion 1.5 meters deep for 30 minutes. The device was built to military standard passing the MIL-STD-810 testing, which determines how equipment holds up under a variety of conditions such as temperature, impact, vibration and humidity. The operation of the device was considered in detail, simplifying the interactions so it can be used effectively in emergency scenarios. IDC researched and accounted for a range of other interactions such as mounting and button operation in cold conditions.

Iterative validation using IDC’s in-house modelling capabilities

IDC’s process is defined by creating products that function reliably in line with the needs of users. The process starts with sketch exploration, quickly ideating and building a vision for the device to move forward.

The ideas generated are validated and tested using our in-house modelling workshop. This ensures the best direction is taken at each step of the process.

Prototyping and testing to meet SAR safety requirements

One of the goals for the Satellite Phone Case project was to integrate the antenna into the main body so that the user could make calls without needing to extend it.

Integrating the antenna came with problems for IDC to
solve. These antennas produce radiation due to their high-power output. Specific absorption rate (SAR) testing was needed to ensure user safety given the proximity of their head to the antenna. Test rigs were produced to adjust both proximity and material properties to find a balance of product size, performance and safety. Performance testing of the antenna was carried out in an anechoic chamber prior to real world calls.

One of the key functionalities of the Satellite Phone Case was to hold the user’s smartphone. The device was designed to be used in extreme and fast paced scenarios and therefore the clamping mechanism needed to be strong and durable whilst offering an optimised user experience.

The IDC team created a robust solution designed to withstand sand and dust. The mechanism had a locking feature to maintain the correct pressure and allow for easier undocking. Some key considerations for the design were in supporting both the smallest device (iPhone 12 Mini) all the way to the largest (Samsung S21 in Juggernaut Case).

The Satellite Phone Case was equipped with an SOS button for emergency situations. The SOS alerts could be sent anytime, from anywhere in the world. They gave access to 24/7 emergency assistance in case a search and rescue mission was required.

The user interaction with the SOS button was carefully considered by the IDC team. This included ease of operation, button identity and resistance to extreme conditions. The SOS button was covered by a hinged door to stop accidental activation, and was activated by being held for 3 seconds. Once activated the top light strobes SOS in Morse code. This light also acted as a torch and helped search parties find the user in rescue missions, it could also be turned off for stealth situations.
