| '''Teledesic''' was a company founded in the 1990s to build a commercial [[broadband]] [[satellite internet constellation]]. Using [[Low Earth orbit|low-Earth-orbiting]] satellites small antennas could be used to provide uplinks of as much as 100 Mbit/s and downlinks of up to 720 Mbit/s. The original 1994 proposal was extremely ambitious, costing over 9 billion [[USD]] and originally planning 840 active satellites with in-orbit spares at an altitude of 700 km.<ref>[http://www.fcc.gov/Bureaus/International/Orders/1997/da970527.txt In the Matter of Teledesic Corporation: Application for Authority to Construct, Launch, and Operate a Low Earth Orbit Satellite System in the Domestic and International Fixed Satellite Service].

| The commercial failure of the similar [[Iridium Communications|Iridium]] and [[Globalstar]] ventures (composed of 66 and 48 operational satellites respectively) and other systems, along with bankruptcy protection filings, were primary factors in halting the project, and Teledesic officially suspended its satellite construction work on 1 October 2002.<ref>de Selding, Peter B. | The commercial failure of the similar [[Iridium Communications|Iridium]] and [[Globalstar]] ventures (composed of 66 and 48 operational satellites respectively) and other systems, along with bankruptcy protection filings, were primary factors in halting the project, and Teledesic officially suspended its satellite construction work on 1 October 2002.<ref>de Selding, Peter B. |
