Directional Antenna, Its Overview And Advantages Over Other Types
This is an antenna type that will be radiating power in either one or even more directions. Because of this capability, this can be generally allowed to maintain the continuous increase of performance to receive and to transmit transmissions. Strength is being focused then power is being transmitted to one direction only in general, thus, the result would be minimized signal loss and optimized signal strength.
Most antennas also have the ability on reducing the amount of interference from different sources. Thus, the most popular and ideal that can be used in most areas where interference is more is the directional antenna. Mostly, an interference would include some common devices used for transmission including some obstructions, microwave ovens, and weather conditions.
There are two very common types of these antennas and these are the corner reflector and the log periodic types. Directional antennas usually are being combined and available for use as antennas for the televisions, specially designed to be used in residential areas. Another common use is as cellular repeaters for receiving and for transmitting signals which are normally out of range in some types of cellular phones.
Antenna directions are usually important when setting up the directional antennas. At times, having the wrong directions cannot really be avoided, and as a result to this, the rendered antenna would become useless. So the best suggestion would be checking first the areas prior to the installation process. Determining the antenna type through this since you know already on the potential interference and obstruction sources.
The direction to where the device is pointing is also a factor that needs to be considered importantly. The device can be most effective if it points towards the nearest source for target signal having the least amount of obstructions and interference. And this is one common reason why the mounting process of this device is often a big issue.
And since there is one general area only is focused, there will be some limitations in the coverage. So whenever the device is intended for use in larger coverage, the disadvantage is becoming less effective. Because of this, the omni directional type of an antenna would be more preferred in larger areas. The omni type has the ability to receive and transmit the signals into several directions.
In open areas like the outside grounds of the house or some other outdoor places are the best areas of installation. Closed spaces usually have more obstructions, and thus, limiting the effectiveness of a device. However, before making a purchase of these antennas, be sure that advantages and as well as limitations are considered importantly.
One very common advantage is the security issue. With these devices, wormhole attacks can be prevented. The attacks would mean that the packet is being forwarded from the attackers by high quality out of band links then replayed to other locations. For this reason, communication disrupted.
And lastly, a very common limitation is deafness that happened when these devices are used. The network performances become limited. Multiple retransmissions can cause the misunderstanding of nodes between the connection because of the mobility and route search has been triggered, and thus, distracting the interactions between the upper layers.
