Lack of Access to Radio Spectrum Constrains Competition and GrowthMost mobile spectrum is controlled by a few incumbents who have a great deal of influence over the market
The Birth of the Mesh PotatoWorkshop in South Africa to ask the question, how to scale WiFi-based voice and data services. Experimented with various options, technologies.
Genesis of the Mesh PotatoMy poor artist’s conceptPrototype literally hacked into an existing Wireless AP200 beta unitsFinal production version.
Mesh Potato FeaturesNot your average access point.UV protected plastic. Single body molding.Accepts anything from 9-40VDC, so can be powered easily by alternative sources… e.g. car battery, solar.Toughened for rural Africa. Capable of withstanding line spikes, power surges, brownouts, anything short of a direct lightning strike.Accepts power via power points, Power Over Telephone Line, Power Over EthernetBased one Open Source technologies. OpenWRT, BATMAN, Asterisk, etc
