The main communication medium on PTAWUG is IRC as this technology enables all the 'wuggers' to speak to each other, using PCs or cellphones, at the same time to easily plan expansion or discuss hardware/software problems on the network.

Many of the skills members learn by using and being involved in the network they apply in their careers.

Network Infrastructure

The lack of a stable periodical income prevents PTAWUG from renting equipment space on commercial towers in and around Pretoria, and all highsites are put up on privately owned properties, with the permission of the owners. Private properties and homes located in high areas are most frequently used for highsites as they have good line of sight to the surrounding areas providing greater coverage for connecting clients. There are currently four towers in use of which three were built by the members as a team and access to the other one was arranged by one of the members. The rest of the highsites are located either on high buildings (like office blocks) or at private residences in strategic places.

  • The IEEE 802.11a (5.8 GHz) standard is preferred over IEEE 802.11b or IEEE 802.11g (2.4 GHz) as commercialization in the 2.4 GHz range over recent years is a cause of high noise levels (measured in SNR or Signal to Noise Ratio), especially with commercial service providers distributing ADSL WiFi Modems freely with their service contracts,.
  • There are 700 km of point to point backbone links running on PTAWUG, mostly using 27dbi grid antennas and running at 48Mbit/s.

Collaboration

  • The Pretoria Wireless Users Group works closely with the Johannesburg Area Wireless Users Group (JAWUG) - they have two links running between them - 22 km and 40 km. PTAWUG also swaps ideas with Cape Town Wireless Users Group (see: http://www.ctwug.za.net/) and Durban Wireless Community.
  • JAWUG and PTAWUG might merge in the future and form Gauteng (the province in which Pretoria and Johannesburg are located) Wireless Users Group - GAUWUG

Growth

In the past year (2007-2008) the network has exploded from 4 users to 500+ users, all helping each other, playing games, sharing tips etc.
The network grows at the rate about 10 new users a month. PTAWUG has also extended its network by connecting to several other wireless networks including JAWUG (Johannesburg Wireless Users Group). The exponential growth is mainly attributable to the free-for-all and open community principals governing PTAWUG, as users contribute their time, income and knowledge freely without hindrance of a governing body
