WiFi Implementations

WiFi is a rapidly evolving wireless network technology that is highly standardised, easily deployed and simple to employ that leads to increased productivity and efficiency for your business or home.

WiFi ImplementationsWiFi, which stands for Wireless Fidelity, in a play on the older term Hi-Fi, is a wireless networking technology used across the globe. WiFi refers to any system that uses the 802.11 standard, which was developed by the Institute of Electrical and Electronics Engineers (IEEE) and released in 1997. The term WiFi was pushed by the WiFi Alliance, a trade group that pioneered commercialisation of the technology.

In a WiFi network, computers with WiFi network cards connect wirelessly to a wireless router. The router is connected to the Internet by means of a modem, typically a cable or DSL modem. Any user within 60 meters or so of the access point can then connect to the Internet, though for good transfer rates, distances of 30 meters or less are more common. Retailers also sell wireless signal boosters that extend the range of a wireless network.

WiFi networks can either be "open", such that anyone can use them, or "closed", in which case a password is needed. An area blanketed in wireless access is often called a wireless hotspot. ACT currently manages a "closed" WiFi network in the Kroonstad area with various hotspots.

WiFi technology uses radio for communication, typically operating at a frequency of 2.4GHz. Electronics that are "WiFi Certified" are guaranteed to interoperate with each other regardless of brand. WiFi is technology designed to cater to the lightweight computing systems of the future, which are mobile and designed to consume minimal power. PDAs, notebooks, and various accessories are designed to be WiFi-compatible. There are even mobile phones under development that would switch seamlessly from cellular networks to WiF networks without dropping a call.

New WiFi technologies will extend range from approximately 90 to 180 meters and beyond, while boosting data transfer rates. Most new notebooks nowadays come equipped with internal wireless networking cards as standard.

ACT can assist you in the setup of a WiFi network (also known as WLAN or Wireless Local Area Network) for your home or small business and connecting to the Internet via your WiFi network.

Benefits of WiFi

  • Speed: Access to the Internet is much faster than Dial-Up and doesn't require plugging into a wired connection like Dial-Up, ISDN, or ADSL.
  • Mobility: Easy mobile access to information on a shared network or the Internet.
  • Simple Connectivity: No wires are required, and accessibility is offered via multiple technology devices. (i.e. a notebook computer, PDA, mobile phone etc.)
