Many people are asking questions, why is the access point there have antenna. But also there is the question asked, there is also access of pointy that do not have the antenna. The answer is simple because in concept access point that does not has a antenna though also has an antenna but antenna placed in the box sometimes access point instead of outside. The Access point that does not have the antenna is usually aimed at the beauty room, as rooms attractions and hotels.
The usefulness of the antenna is deliberately created by the vendor are as media receiver and data transmissions. Basically a network administartor must understand how the workings of an access point, starting from the preparation of the transmission of radio signals that are used to get process identification device access point with the client device such as a laptop, PDA, and so on. One of the properties of radio waves is Ricochet when the radio wave on hard objects that are around him, it is the same as with the flashlight in navigate to purmakaan glass, must be bounced.
Wireless adapter in the device the recipient client will radiate the radio wave in all directions generally, except should be replaced with specific sectoral antennas such as antenna, grid and so on. Radio waves will spread where mana, and consequently will occur, for example, there is Ricochet Ricochet waves directly to the access point, there is exposed lights, glass, wall walls before reaching the access point. Due to the bounce this is the Access point will get the same signal from different directions and in a different time. This event was called with Multipath.
Basically an antenna access point are half duplex, meaning that it can only send and receive at one time, and cannot send and receive at the same time. With the antenna, the quality of the acceptance and delivery will be better. Basically the access point is to have one, two, three and more antenna, the number of antenna is usually depends on how sensitive the device access point to use. With the existence of antenea in access point wireless network quality will increase dramatically as a whole.
