If we put a PC or laptop we are far enough away from the WiFi transmitter, then we will have trouble catching the WiFi signal. As another example if we are in a certain space, where there is a partition divider quite a lot that separates us from the WiFi transmitter, then we will also have difficulty to get the WiFi signal.
Well, to overcome this, we can use a device called a repeater. The device is usually shaped like a box with multiple antennas, at least 2 antennas (some other types are not equipped with antennas). More on the definition of repeater and function and how it works, see the explanation below.
Repeater is a device that serves to receive signals that contain data in a network. By using a repeater then network coverage will be wider. The Repeater receives a signal and then reradiates the signal identical to the original signal, but in a different way. Generally the repeater reradiates the signal in a different frequency than the original signal frequency.
So if you meet the term in the market, you don't need to be confused because it all refers to the same device, which is a repeater. Repeater itself there are several types, namely 1) telephone repeater, 2) optical communications repeater, and 3) radio repeater. Each repeater has its specific function depending on its specifications.
The first type of repeater is telephone repeater. As the name suggests, you'll already be able to guess. Telephone repeater is a type of repeater used on the telephone line. On the telephone cable channel, the signal is usually degraded due to distant mileage. Therefore the repeater should be used to allow the signal to be received by the phone user clearly.
The second type of repeater is optical communications repeater. This Repeater function to strengthen the signal coverage in fiber optic cable. In fiber optic cables, digital information is physically tangible as light pulses. Light pulses (in Indonesian is called Light Pulse) are formed from photons. These photons can be scattered randomly in the fiber optic cables.
The third type of repeater we call the term radio repeater. This type of Repeater, as its name suggests, serves to strengthen radio signals. Generally, this type of repeater has one antenna that works as well as a receiver and transmitter. This type of Repeater will change the frequency of the signal received before retransmitted. Signals transmitted by the repeater signal will be able to penetrate the barrier object.
The Repeater function is to extend the WiFi network coverage. The hardware on the repeater has been programmed to receive the WiFi signal from the transmitter for later amplified. Once the signal is strengthened, the repeater will redistribute the signal. Thus the WiFi coverage will be wider.
How Repeater Works
Repeater function to extend the WiFi network coverage. This is done by accepting the data signal and then emitted again. Before re-emitted, the signal that has been entered into the repeater is reinforced first.
In the processing of the data signal into it, the repeater has two commonly used systems. Such systems are analog repeaters and digital repeaters. In the repeater analog, the data signal is transmitted in the form of analog data where the power consumption is directly proportional to the amplitude or magnitude of the signal transmitted. While digital repeaters transmit data signals in digital form. Digital Data is sent in binary form, which is represented by numbers 1 and 0. Additionally digital repeaters also perform additional processes on the signal data processed.
That is the sense of repeater and function and how it works. Now you understand that the main role of the repeater is to receive signals from a network and then re-transmit the signal to be wider (Rangenya).
