Individual: Wireless Signals Erwin Pancho IT/242 February 7, 2012 Wireless Signals First of all lets define what a wireless signal is. Wireless internet/technology creates a network by sending radio-frequency signals between your computers to share information. This allows wireless networking technology to happen without the use of wires and makes it easier for other computers on the same network to communicate with one another.
In wireless networking, a peer-to-peer or in other words point-to-point wireless network means that each computer can communicate with every other computer on that same network. Wireless networks that use client/servers have an access point. An access point is a wired controller that receives and transmits data to the wireless adapters installed in each of the computers. There are four main types of wireless technologies which include but not limited too are Bluetooth, IrDA, HomeRF, and Wi-Fi (wireless Fidelity).
Bluetooth wireless technology allows users to enable links between their mobile computers, mobile phones, portable handheld devices, and Internet connectivity, which require no wires to be involved or that is needed. It is mostly used for devices such as cell phones, PDAs, wireless headsets, computer hardware, headphones, MP3 players, etc. Bluetooth technology is supported by application and product development in a broad range of market subdivisions, which include software developers, peripheral and camera manufacturers, silicon vendors and many more.
The second type of wireless technology out there is IrDA, which is an acronym, which stands for the Infrared Data Association. IrDA uses a series of infrared data pulses to transfer data from one device to another. Since IrDA uses infrared light, the communicating devices must be in direct line of sight with one another. IrDA was the earliest wireless technology and it was used for such things as television remote controls, garage door openers, and other more primitive wireless devices.
Today’s technology now has improved the use of IrDA’s standards for data transfer speeds and other important features. The third type of wireless technology is HomeRF, which stands in this case (RF stands for radio frequency) was an alliance of business that developed a standard for wireless data transfer, which is called Shared Wireless Access Protocol also known as SWAP. SWAP-based networks are usually point-to-point. Since this technology lacks access point, HomeRF networks are significantly cheaper than the other viable wireless network technology. This is where Wi-Fi comes in handy.
