The World Of Wireless Network Technology

A computer network that uses wireless data connections for networking is called a wireless network. It allows the Internet usage of houses, offices, and businesses to minimize cost and increase efficiency.

Wireless Network TechnologyA wireless network serves the same purpose as a wired network. The basic difference is that a wireless network avoids wiring and labor costs, thus is cheaper and faster. A wireless network enhances an existing wired network facility. Hence, a network connection is impossible without a wired connection.

Wireless network technology uses Radio Frequency technology. When RF current passes through the antenna, an electromagnetic field is produced and broadcasted in the space. A wireless network is based on an Access Point (AP). The access point broadcasts the signal detected by the computer and tunes to it. The computer must be connected to the AP to join a network connection. In order to connect with the AP, a computer must be operational with “network adapters” which are usually built in the computer. However, if not, then any device can be made wireless with the use of add-on devices. These add-on devices can be plugged into empty slots such as, (the USB port, expansion slots or PC card slots) in the computer or notebook machine.

Wireless Technology Standard: There are various wireless technology standards that must be considered before making a buying decision.

  • 802.11b: commonly known as the Wi-Fi. It was first introduced a decade back.

  • 802.11g: this version came after the 802.11b with greater speed and range. It is most commonly used these days.

  • 802.11n: this version is an improved version of the 802.11g.

Wireless speed and access

Network speed depends on the nearness to access point. The closer it is to the access point, the faster is the connection speed. The environment also impacts the connectivity speed. If it is not favorable, interference problems may arise.

Wireless Obstruction

Wireless Network TechnologyInterference is of vital concern with all types of radio communication. Wireless connection therefore, is also not an exception. Interference is most likely to occur indoors due to the strange types of construction material, which absorb the radio waves or reflect them. This is what affects the strength of the network signal causing interruption.

Likewise, other devices that use radio frequency technology like the cell phone, microwave ovens, and can be the source of interruption as they function in the 2.4 frequency range as the 802.11b, 802.11g and 802.11n networks do. Network interruption cannot be omitted and sometimes it can affect the usage of the network connection.

To avoid connectivity issues, the hardware device can be put to another location.

A wireless network can be connected via a wireless equipped computer, which is authorized to prevent unauthorized people from connecting to it. Moreover, data can be protected from misuse. The data can be encrypted using the Wired Equivalent Privacy it is not a secure option therefore must be avoided. Wi-Fi Protected Access is a stable choice for it provides better protection with passwords. In order to secure vital information, data encryption must be necessary.
