As alternative transmission technology to the above mentioned systems, part of our development focusses on practical use of satellite based radio systems, which allow access to very remote locations, where no direct connection to terrestrial networks currently exists.
In the initial prototypes, special M2M-modems are in use, which utilize the well known Iridium-communication network. This network currently consists of 66 active satellites, which hover in low earth orbit, approximately 800 km above ground. These are being permanently re-positioned. Under certain reception conditions, a global and disconnect-free availability of our mobile devices is conceivable. Data transmission is being achieved using a SMS-like service, without any considerable delay.
We expect that current limits on bandwidth will go away. Transfer volumes will clearly increase in the future, since a great number of upcoming and established satellite providers have already vowed to built a more effective network.
