Pretoria Wireless Users Group
South African wireless community networks are wireless networks that allow members to talk, send messages, share files and play games independent of the commercial landline and mobile telephone networks. Most of them use WiFi technology and many are wireless mesh networks. A wireless community network may connect to the public switched telephone network and/or the Internet, but there are various restrictions on connectivity in South Africa. Wireless community networks are particularly useful in areas where commercial telecommunications services are unavailable or unaffordable. 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.

Map Of South Africa
A map is a symbolic depiction of interrelationships, commonly spatial, between things within a space. A map may be annotated with text and graphics. Like any graphic, a map may be fixed to paper or other durable media, or may be displayed on a transitory medium such as a computer screen. Some maps change interactively. Although maps are commonly used to depict geography, geographic elements, they may represent any space, real or fictional. The subject being mapped may be two-dimensional such as Earth's surface, three-dimensional such as Earth's interior, or from an abstract space of any dimension. Maps of geographic territory have a very long tradition and have existed from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'of the world'. Thus, "map" became a shortened term referring to a flat representation of Earth's surface. History Maps have been one of the most important human inventions for millennia, allowin ...

WiMAX
Worldwide Interoperability for Microwave Access (WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media access control (MAC) options. The WiMAX Forum was formed in June 2001 to promote conformity and interoperability, including the definition of system profiles for commercial vendors. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL". WiMAX was initially designed to provide 30 to 40 megabit-per-second data rates, with the 2011 update providing up to 1 Gbit/s for fixed stations. IEEE 802.16m or Wireless MAN-Advanced was a candidate for 4G, in competition with the LTE Advanced standard. WiMAX release 2.1, popularly branded as WiMAX 2+, is a backwards-compatible transition from previous WiMAX generations. It is compatible and interoperable with TD-LTE. Newer versions ...

Independent Communications Authority Of South Africa
The Independent Communications Authority of South Africa (ICASA) is an independent regulatory body of the South African government, established in 2000 by the ICASA Act to regulate both the telecommunications and broadcasting sectors in the public interest.

Broadband Networks
In telecommunications, broadband or high speed is the wide- bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast Internet access. The transmission medium can be coaxial cable, optical fiber, wireless Internet (radio), twisted pair cable, or satellite. Originally used to mean 'using a wide-spread frequency' and for services that were analog at the lowest level, nowadays in the context of Internet access, 'broadband' is often used to mean any high-speed Internet access that is seemingly always 'on' and is faster than dial-up access over traditional analog or ISDN PSTN services. The ideal telecommunication network has the following characteristics: ''broadband'', ''multi-media'', ''multi-point'', ''multi-rate'' and economical implementation for a diversity of services (multi-services). The Broadband Integrated Services Digital Network (B-ISDN) was planned to provide these charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
