Frost & Sullivan’s intent is to aid those end users and decision makers responsible for purchasing, deploying, or using personal satellite communications devices. The company found it valuable to compare the features and performance of the latest industry model, Inmarsat’s IsatPhone Pro, with those of the market leader and industry standard, the Iridium 9555™ satellite phone. Frost & Sullivan also compared Iridium’s network of 66 low-Earth orbit satellites to that of Inmarsat’s constellation of three geosynchronous orbit satellites — qualitative and quantitative analyses were conducted. For the qualitative portion of this analysis, the following features for each phone were evaluated:
- Size and weight
- Keyboard
- Display
- Antenna
- Battery use and charge life
- Battery charger
- Construction and overall feel
