Omni Directional Antenna

WiFi is a revolutionary form of radio frequency reception in It is also known as 802.11 teknoiogi normally used to transport signals from one location to another. Digital transmission is done through radio waves in order to achieve the transfer of data packets in wireless networks. Special antenna, known as WiFi antenna needed for reception of radio waves. In a network card (NIC) and the Wireless access point, there is actually an integrated antenna that can not be viewed or changed by the user. However, there are plenty of other wireless LAN devices that have an antenna that can be changed / replaced, thus providing flexibility to the network by enabling the selection of the antenna that has the desired characteristics.

It is required that the purchase of a WiFi antenna actually serve a specific purpose in a wireless network. Working standard 802.11a, 802.11b and 802.11g, entirely too dependent on signal strength,

There are basically two types of WiFi antennas in terms of use, and differences in system and installation.

Directional antennas: This type of WiFi antennas that can generally be used for point-to-Point or Multi-Point, depending on the configuration of the wireless LAN Wireless. A common directional WiFi antenna is Type: Backfires, Yagi antenna, panel directional and directional dish type.

Omni Directional Antenna  Antenna WiFi is this type of antenna used for Point-to-Multi-Point system. This tool can serve as the main antenna to distribute the incoming signal, to other computers or peripherals in their networks. Omni directional antennas help

WiFi Antennas How it Works

Access points, which consists of antennas and routers, is the main source of transmission and reception of radio waves. Radio signals transmitted from the WiFi antenna is directly picked up by WiFi receivers. The receiver is equipped with a WiFi card and have the ability to capture the radio waves at certain frequencies. Every time the computer receives a signal in the range of a WiFi network (Wireless Internet Access), WiFi card read signals and create a wireless Internet connection between the user and the network.

One of the most important characteristics of a WiFi antenna is the range. The range of the signal depends on several factors, including the output power of Wireless LAN or router, Wireless LAN signal reception power is delivered, and the obstruction factor, and so on. Therefore, if necessary it should choose a better antenna, which can amplify the signal with maximum power. Efficiency of wireless systems must be upgraded with the help of an external antenna, which can be set to several directions or Omni directional quality for large area coverage and narrow, or the support link point-to-point links between buildings, high-end antennas are very useful. Directional antennas can help to reduce the number of access points required facilities, namunpun not necessarily required.

There are many kinds where people have modified the antenna WiFinya, in order to obtain the expansion of the range. Problems of use and flexibility must also be taken into account when choosing a WiFi antenna for internal or external. A good choice if someone wants a better network connectivity and efficient way to transfer data in a wireless network. Therefore, it is best to first consider before buying a WiFi antenna, whether choosing a WiFi antenna type Directional or Omni Directional Antenna.
