History: The U.S Federal Communications Commission, in 1985, made bands of the radio spectrum available for use by the public, with no license needed, and this opened the way for Wireless Internet. The inventors of WI-FI (Wireless Internet) originally developed the technology for use with cashier systems. This was the NCR Corporation with AT&T , later known as Lucent Technologies and Agere Systems.
The person responsible for making the public aware of WI-FI is Vic Hayes, and is called the father of WI-FI, and the first Wireless Internet product was called WaveLan.
Today: From this year 2010, wireless internet is a feature of most laptops, as the manufacturers race to keep up with growing global trends. No wires are needed for local area networks and client devices. With this cost effective way of using the internet, many businesses and corporate environments have cut their costs of network infrastructures. As long as you use a standard wireless internet device, you are able to use the internet wherever you are in the world.
Wireless internet has taken off to such an extent that almost everyone using a laptop for business and travel uses it. It is everywhere, down to the little man in the street who sees the benefits of reduction in costs, the wide-spread availability, and freedom of movement (no wires). Wireless internet is provided by hot-spots, which is why large companies and restaurants, hotels and airports, use this as a client-attracting marketing strategy, as part of their client service, to offer their clients free use of wireless internet hotspots at these locations.
Most Personal Computers, Laptops, Video Games consoles, and palm sized computers, MP3 players, smart-phones, mobile phones and personal digital assistants, as from 2010, have installed as standard, an IEEE 802.11 device, which makes them wireless internet compatible. All of these devices, and many other wireless internet enabled devices can connect to the internet, while within the range of an access point (wireless network) already connected to the internet. These wireless networks are called hotspots (access points).
The coverage of an access point or hotspot, can be as small as a 50 square feet or as large as a few square miles. This all depends on how the access points are grouped and how they overlap to provide coverage. The wireless networks interconnect the access points to form hotspots.
The Future: Wireless internet has made networks used by large and small business environments all but redundant. All the former wired technology is offered with much better benefits and capabilities as wireless internet offers a secure computer networking gateway, firewall, an detections system for intrusion, and a DHCP server plus many other benefits, cost being a large factor taken into consideration.
