The Motorola Iridium 9505 features a GSM Network connection with antenna, no Wifi or Bluetooth.

Satellites phones connect to telephone network through satellite instead of terrestrial cell sites. They, thus, cover almost every geographic point on Earth, even on remote areas with no cellular coverage. The first satphones circulated during the late-1980s with a large antenna. Generally they didn’t differ much from a normal mobile phone as per appearance.

The satellite network systems have two categories. There are the systems that use satellites in geostationary orbit (GSO) in 35k kilometers above Earth’s surface and others in low Earth orbit (LEO) around 1km above the surface. The second category offers more consistent signal with high-speeds and no gaps. There as well different sattelite services, such as Immarsat-based ones and Iridium, as of the present model, the Motorola Iridium 9505.

The calling costs are relatively high, according to terminals and traffic. Prices may vary from 0.80$ per minute until up to 15$! Notable as well is the fact that in some countries there are restrictions on the use of satphones. For example in North Korea, it is prohibited while in Russia and India monitored closely. There are many security concerns. Until today satphones need additional encryption developed.

That was just a snapshot on the presentation of the techmuseum series. Indulge more into the history. Continue reading more about the present model, the Motorola Iridium 9505 here. Alternatively, find more exciting stories here.
