The wifi technology has proved to be of great use and has stood on the expectations of the users. It is the wifi antenna power that is considered to be the most important aspect in the area of development of the wifi technology. It is possible to extend the given range of the wi-fi system (currently running 802.11 IEEE standard) by installing and configuring an external antenna, and it is logical that with more range more mobility can be provided to the user.
There are various types and kind of antennas available in the market, for choosing the appropriate one we have to first analyze all our requirements. We should judge our needs and whichever antenna satisfies the requirements should be taken. If the requirement is to have a better mobility of the system then the directional antennas should be taken. It is widely used in point to point transmission.
There is a second type of antenna available in the market; these are called omni directional power antennas. When an antenna transmits waves, they are propagated in all directions. Hence these antennas can serve as a base antennas, can transmit the data to various nodes in the network like wireless printers, laptops, PDA, etc. These antennas have some shortcomings too. These bi-directional antennas cannot be used in point to point transmission.
There is a third category of antennas, which can be used in multi cast communication, in other words in order to have data transmission between a point and multi points, point to multi-point WiFi antenna power options are available. It is very useful when we try to establish and share wireless local area network or try to establish a high speed internet connection. It is also applicable in the set up of wireless access points.
Knowing and understanding the qualities that are needed for an efficient and properly working network and requirements of our system is very crucial for choosing the right kind of antennas. Choosing the right type of power antennas can help in utilizing the facility of wifi network of the system.
If someone does not understand the whole technicality of the wireless networks, and its requirement, it is advisable to get in touch of the concerned technicians before buying any type of antennas.
Just knowing the range offered by a particular antenna is not the only condition which be taken care of. In other words there are different factors also which must be considered, in order to calculate the total range of he antenna, these factors are the power output of the wireless network interface card, and also the strength of the receiving wireless card (the card of the destination node). These factors play an important role to determine the effective range of the antennas.
