Radiating and receiving RF Electromagnetic frequency in all directions in a plane, Omni Directional Antennas can be external and in-built. These antennas are widely used in wireless devices like cellular telephone set and wireless routers. The coverage pattern of the antenna looks like a sphere. For mid to high gain performance, in-built Omni Directional Antennas are used. If higher level of gain performance is required detachable antennas are used. These Wireless Antennas are available in several designs namely rubber duck, spider, ceiling mount, etc.
Antennas have become one of the essential parts in multimedia accessories. It is in the top priority list among many industrial and residential sectors. The wireless antenna takes upper hand in the diversity effect at the transmitter, receiver or both. The diversity effect includes the transmission of numerous waves of radio frequency that helps in increasing the speed of data with less error rate. There are different types of Wireless Antennas available in the market. Some important types of antenna are highlighted in the below listings.
A Wireless Antenna is an important component of the complete wireless network. It is responsible for sending and receiving the radio waves over different frequencies. The power gain of an antenna decides its strength. It is measured in decibels (dB). Selecting the right antenna is one of the most common problems while installing a wireless network. One must be aware of the frequencies that are compatible with the wireless and system, the signal strength required etc. Also, a comprehensive knowledge about the types of Wireless Antenna will contribute to a wiser choice.
MIMO or Multiple Input Multiple Output is a wireless technology that helps in transmitting wireless signals over multiple antennas. MIMO is generally used to improve the Wireless Range, Bandwidth, Interference and ECHO handling features of the new generation of wireless routers. Generally, there are three different types of MIMO techniques:
When designing any system, engineers and system architects usually want to know how well the various components of the system will perform. In a microprocessor, logic or other digital system these questions usually are answered in terms of clock speeds, instructions per second or data throughput. With wireless communication, the most common performance questions involve range.
This article will discuss design considerations that provide the maximum transmission distance for digital wireless radio communication in the FCC unlicensed bands, while minimizing the system power supply requirements, thus facilitating solar or wind powered remote applications.
Why do you need to point your wireless antenna? Industrial wireless antennas come in a very wide varity of shapes, colors and designs. Diretional antennas need to be pointed at eachother in order to opperate. Omni-Directional antennas still need to be used in a way that allows for the largest amount of "gain" or signal that is transmitted or recieved.
