With the local authority’s permission, a cooperative comprising ten local and respected people was formed. This group designed the network layout, and built and installed a dozen solar powered mesh network stations. These are mounted on and inside houses around Mankosi.
These are organised in what we call a mesh network and WiFi stations cover an area of 30 square kilometres.
Zenzeleni constitutes a fully fledged Internet Service Provider (ISP), equipped with an Internet and Voice-over Internet Protocol gateway, and a billing system in isiXhosa run by community managers.
The Independent Communications Authority of South Africa (ICASA), which grants licences to ISPs and collects fees where necessary, granted Zenzeleni a licence exemption; so it costs Zenzeleni nothing in fees to operate infrastructure and sell services. The community only has to pay for the backhaul Internet connectivity, which they can get at wholesale prices from companies like EastTel and OpenServe, and for educational use from TENET.
Any device – even a low to mid-range smart phone – that’s WiFi-enabled can access the network. There are two dedicated wireless connections to “point of presence”, or POP, fibre in Mthatha.
Zenzeleni’s voice calls and data costs are much cheaper than what’s offered by the big mobile operators. For example voice calls can cost 20c a minute rather than the standard R1.50 or more while data costs can be between 20 and 40 times cheaper.
The solar powered stations also charge cell phone batteries less than what’s usually charged by spaza shops or shebeens. Those shops also tend to be some distance from the village, so people save time as well as money.
