There was so much hype about wireless networking that it is commonly tough to get to the real issue : do you need it? To establish whether your notebook PC wants to have wireless networking capacities, you want to understand what it is first. WLAN stands for Wireless neighborhood Network or Wireless LAN. There are more wireless networking standards, for example Bluetooth, but the 802.11 standard is the preferred networking solution. The Wireless Network interface was developed originally for interfacing among PCs connected thru a neighborhood network, but it is now also being used for Voice over Web Custom ( VoIP ) and web access, like the standard Local Area Network interface. A Wireless Networking environment has no use for advanced wiring to accommodate information sharing and web access. The wireless network uses a number of Wireless Access Points or Wireless Routers to broadcast the signal. An Access Point has an antenna and an Ethernet port, which has to be hooked up to a broadband modem for web connectivity.

A Wireless Router adds several more Ethernet ports to permit a mix of wired and wireless connections.

The Access Point or Router acts as the radio frequency transmitter and receiver ( radio frequency electromagnetic waves are the medium thru which information packets are sent and received ).

This Access Point interfaces with devices ( PCs, PDAs, IP Telephones , and other Access Points ) which use 802.11 wireless adapters. Wherever there's an 802.11 wireless access point, a wireless networking-capable device can access that network and, often, the web.

Do you need Wireless Networking in Your Notebook Computer? Whether you want wireless networking depends wholly on you. Wireless networking capacity is always a superb feature to have in a notebook computer, but there are eventualities where wireless networking is unquestionably mandatory. If you would like to have a neat office or home network, wireless networking is for you.

Likewise , if there are numerous users in your local network or if the number of users is predicted to increase, a wireless router isn't restricted by the amount of Ethernet ports on the router. If you are a contractor, a journalist, or in another position where you often travel, Wireless Networking is invaluable.

Wireless Networking is the most generally used form of public web access all around the world. With a wireless networking card, you are assured a Net connection, so long as you will find a wireless hotspot. For interfacing with private devices like PDAs and cellular telephones, Bluetooth is a commoner option, but Wireless Networking is totally required for wireless net connections.
