More on O3B Sat-Based Wireless Internet

Two weeks ago I reported on Google's funding of a project to offer satellite Internet connectivity to the "other three billion" (O3B) people without access to the Internet. Russell Southwood, at talked to one of the entrepreneurs behind the plan and received some more information on the systems.

O3B will not be selling bandwidth to consumers. Initial service from the eight MEO satellites will reach only the African continent through 30 spot beams, each 500 kilometers in diameter. Each spot beam provides a combined 1.25 Gbps upload and download data rates. O3B sees the service being used instead of fiber or microwave links to provide connectivity to remote mobile phone, WiMAX, EVDO and similar cell sites. A 3.5-meter satellite dish is needed at the Earth station, along with a terminal.

See Southwood's article Google Satellite bandwidth details for more information.
