Outernet

Outernet provides a free service with global reach designed to enable low cost connectivity to communities that would otherwise be out of touch.

This post is almost completely sourced from the Outernet web site. My Outernet kit just arrived and these are the components:

Our filecast differentiates itself from a traditional broadcast by sending information as data files, so content is no longer limited to video and audio. Now, any content format can be sent over a radio signal. Receivers automatically cache these files locally, so users can enjoy flexible, on-demand access to content.

With the global reach of satellite broadcasting, this system is paving a new way to distribute, access, and consume content.

Read on to learn more about filecasting, the Filecast Center, or applications of technology. Visit our product page to learn more about our receivers.

LIFE CYCLE OF A FILE

TRANSMISSION

A file is converted into a radio signal and transmitted around the world over satellites.

This process is similar to what happens with satellite radio, but the file can be in any format.

Read more about the signal.

 

DEMODULATION

The receiver catches the radio signal and extracts the original file.

Once extracted, the files are automatically saved on the receiver’s internal drive.

Read more about the hardware.

ACCESS

The receiver acts like a local server for the saved content, and emits a WiFi hotspot.

Users can connect to this WiFi with any device to access the saved content.

SIGNAL

Our signal is broadcast over three Inmarsat satellites, offering coverage on continents and on the open seas. These three birds are:

  • I-4 F1 APAC (Asia-Pacific), at 144-degrees East
  • Alphasat, at 25-degrees East
  • I-4 F3 Americas, at 98-degrees West

Our frequencies are:

  • APAC: 1545.9525 MHz
  • Alphasat: 1545.94 MHz
  • Americas: 1539.8725 MHz

Bitrate is about 2kbps, or 20MB of content per day.

Outernet L-Band hardware can also be used for Inmarsat reception, including SafetyNET, EGC, and AERO.
