The VoIP bicycle works like this: Someone sits on the bike and pedals to generate power. That drives power for the low-power computer. A regular telephone handset is connected to a circuit board that plugs into the computer. A caller can use the phone to place a call over a wireless Internet connection using the 802.11b WiFi radio standard.
Since the bike has a directional antenna with a range of 7.2 miles, the call can be carried that distance until it hits another antenna. That antenna transmits the call another 7 miles and so on. So the VoIP bike and its network of antennas can actually extend the range of the phone to 62 miles. Once it reaches a given destination, Inveneo can switch the call into the regular phone network, and direct it to any phone worldwide.
The wireless technology provides bandwidth of 1 megabit a second, or enough to carry 15 simultaneous phone conversations with decent quality. The bike has a solar panel for the day time, but pedal power can supply electricity at night. Hence, the bikes can provide 24-hour-a-day phone service, given enough pedalers. Each bike can be set up for a cost of about $2,000.
