When looking for or buying Wireless…

Many people use wireless networking, (also called WiFi or 802.11 networking) in their day to day life, to connect their computer at home, in the airport, coffee shop, library, or hotel to the internet. More and more people are using wireless networks to connect their computer at work to their internet network, because of mobility, requirement in warehouses, factory, conference room, staff work-areas and remote site visits.
After a wired infrastructure at the “head-end” of your local network is the place your are ready to add and manage an additional wireless network permitting you to access the Internet from the convenience of a laptop, Notebook,or Netbook.
The most important standards documented in the series are named 802.11a, 802.11b, 802.11g, 802.11n. These are the standard speed and for wireless technology.
There are a number of components that make up a WiFi network.

They are:

1. Internet Service Provider or ISP or a intranet network
2. Broadband Mode
3. Router
4. Ethernet Switch
5. Wireless Access Point
a. Wireless AP Controller
6. Wireless Network Adaptor, now builtin to most laptops, Notebooks, and some desktops.

Devices 2, 3, 4, and 5 in some forms of functions are combined into a single box. Wireless local-area networks (WLAN) based on 802.11a, b,g technology has been widely constructed for commercial benefit over the last ten years, but there are still issues in large deployment in a corporate environment. Some of those challenges are management , QoS, shared bandwidth, phasing 802.11n equipment into an existing a/b/g infrastructure with out a forklift upgrade and many other issues.
Wireless 802.11n technology gives higher data speed and increased range and promised to deliver more reliability, stability and coverage than earlier standards.

802.11n meets all the requirements for the next-generation WLAN.

  • Increase data throughout, with a maximum speed of up to 144 megabits per second (Mb/s) and increased speeds of up to 300 Mb/s in the future using the same WLAN infrastructure.
  • Less signal interference and improved aggregation of frames
  • Lower cost due to fewer access points and switches
  • Higher speed and greater reliability, increases customer satisfaction
  • 802.11n technology is compatible with the other wireless technologies 802.11 a/b/g and other Operation systems
