South African wireless community networks
South African wireless community networks are
Wireless User Groups (WUGs) in South African cities build up infrastructure and applications, as well as training members in wireless technology skills. Therefore, WUGs provide a fertile ground for new technology and applications that may have large social benefits in informal communities and rural areas of South Africa and neighboring countries.
Background: South African Telecommunications Environment
South Africa has the best developed and most modern telephone system in
However, although there are now over one million broadband subscribers, mostly using
Telkom provides relatively poor voice and internet service in underdeveloped rural areas of South Africa, although it is investigating ways to improve service using wireless technology.[8] The Independent Communications Authority of South Africa has licensed several small telecoms firms to operate regional networks in remote, under-served areas of the country.[9] Bokone Telecoms in Polokwane and Amathole Telecoms in the Eastern Cape are experimenting with WiMAX technology to provide service.[10] However, due to relatively high costs and low revenue potential, these initiatives are moving slowly. There is room for more innovative approaches.
Currently, VoIP (
Sample City-Based Wireless Community Networks
Most cities in South Africa have one or more non-profit groups collaborating in running Wireless User Groups. Descriptions of a sample are given below, with information derived from their web sites.
Johannesburg WUG (JAWUG)
Jawug is located in
Jawug has a membership base of approximately 300 locations, and is constantly expanding.
Pretoria WUG (PTAWUG)
The Pretoria WUG was founded on 28 July 2007. The PTAWUG constitution guarantees openness, free participation and equality to all members of the Wireless User Group. PTAWUG is exclusively funded by donations from the community. Volunteers conduct highsite installation and maintenance in their spare time. PTAWUG is the 5th largest wireless network organization in the world with about 600 member connections (7 October 2009).[18] To avoid rental costs, all highsites are on privately owned properties, mostly in high areas with a good line of sight to the surrounding areas. The network has a number of towers, with the other highsites located on tall buildings or at private residences in strategic places.[19]
The Pretoria Wireless Project is another community based network in the city, which has been connected to the Pretoria WUG network as of 3 February 2008.[20]
Cape Town Wireless User Group (CTWUG)
The Cape Town Wireless User Group has been around since about 2005 as a small network between friends. Since then it has grown to a citywide network. CTWUG has over 1500 user sites all around Cape Town - spanning all the way from Houtbay to Stellenbosch and into the Helderberg. CTWUG is a non-profit organisation that is geared towards community based wireless networking with a focus to promote the use and understanding of wireless equipment in order to build a citywide free wireless network. The building of this network forms a social and interactive community where people with an interest in expanding and improving the network donate time, money and equipment to the group.
CTWUG runs many network enhancements, including a GameTime system which stops all bulk traffic during certain hours for gaming and other high-priority network uses. CTWUG puts a lot of priority in making sure the network is usable for as many applications and uses as possible.
No monthly or annual fees of any kind is asked for membership and all contributions are completely voluntary. CTWUG maintains good vendor relationships to ensure high quality equipment is used and supplied for all network links.
Durban Wireless Community
The Durban Wireless Community was founded in December 2004 by a group of people interested in 802.11 a/b/g wireless technology in Durban, the third most populous city in South Africa. The first meeting in January 2005 had 4 attendees. The group now has about 200 people on the mailing list and about 15 live nodes on the network spanning from Bluff to Umbilo, Morningside, Town, Tollgate and Westville. Goals of the non-profit group, which is free to join and open to all, include educating the public about wireless technology, and learning more about the technology. The Durban Wireless Community has close ties to JAWUG.[21]
Potchefstroom Community Network
The Potchefstroom Community Network is a non-profit grassroots effort by members of the community to provide a broadband network between its members, using inexpensive off-the-shelf (WiFi) radio networking equipment. The network operates in the license-exempt 2.4 GHz frequency spectrum.[22]
Stellenbosch Community Network
The
iNethi Community Network
This is an exception to the urban norm described above, namely hobbyists who generally have commercial internet access but want something more. In this case, which is currently located in Ocean View outside Cape Town but intends to expand, most users have no other internet access; also, the network hosts many resources in its "cloudlet" server/s, such as user-generated video-sharing applications; such local resources are free to use, while access to the wider internet is on the basis of prepaid vouchers.[24] The project is supported by the University of Cape Town.
Rural Wireless Community Networks
Although the city-based community networks are typically run by hobbyists who may be primarily interested in experimenting with technology and avoiding high broadband charges while playing Internet games, they serve also as test beds for more serious projects and training grounds for wireless network engineers that may benefit projects in poor rural and informal communities. In these communities, wireless mesh networks may have great medical, educational and economic value, giving affordable telephone and internet access when coupled with initiatives such as One Laptop per Child that aim to provide low-cost devices[25] - assuming the regulator continues to remove obstacles to deploying WiFi community networks.[26]
Meraka Institute
The Meraka Institute is a government-backed organization to promote ICT development. The
- Social research into how projects in communities around South Africa, Angola and Mozambique are able to create sustainable community-owned wireless infrastructure, with focus on applications in health, education and related service delivery areas.
- Ways to overcome technology barriers and enable bottom-up creation of wireless access infrastructure. This includes research into mesh networking, low cost voice/messaging devices, low cost access points and antennas, and network security. Experimental test bed mesh networks have been installed in Pretoria and Mpumalanga to understand issues such as scalability and quality of service.[27]
Peebles Valley Mesh Project
The Peebles Valley mesh project is using wireless mesh networking as a low cost first mile solution connect people to the internet and each other. The project is testing if a rural community can take ownership of the network, with a trial community-run WUG near the Kruger National Park in the Mpumalanga Province.[29] The project uses "Cantennas" to connect to the wireless mesh network. These are small, self-constructed antennas made from locally available material connected to a low-cost WiFi card plugged into a computer.[30] Although sponsored by the Meraka Institute, the project members state that what they are doing is illegal under current laws.[31]
UWC Telehealth
Another project, UWC Telehealth, is testing a system in a remote rural part of the Eastern Cape in South Africa that lets nurses and doctors use a wireless IP-based communication system to conduct patient referrals, request ambulance services and order supplies.
Zenzeleni Networks
This project is a "descendant" of the UWC Telehealth one above, in that UWC applied its learnings to support a more extensive project. After initially providing a local VOIP service, full internet was provided as smart phones became more widespread. Starting in Mankosi in the Eastern Cape, Zenzeleni expanded first to Zithulele and at time of writing, is planning further expansion.
