How Can We Get the Longest Distance by Using Wireless Receiver and Remote Controller?

Question:

How Can We Get the Longest Distance by Using Wireless Receiver and Remote Controller?

Answer:

Generally speaking, remote light switch kit consists of wireless receiver and remote controller. You can control almost all the equipments by using the remote light switch kit. Setting the wireless receiver on the equipments, using the remote controller to transmit RF signal to the wireless receiver. When the wireless receiver gets the RF signal, it can control the equipments.
Some customers will find that the actual distance is not so long in real practice. In this case, you may doubt that the products are of poor quality or the working distance is wrong. That is not true. Here we want to recommend that all the working distance of our remote light switch products is a theoretical data, it shall be operated in an open ground, no barriers, no any interference.
Take remote light switch model 0020144(S1M-DC12-ANT2 & CB-1) as an example, the distance 2000m is a theoretical data, it shall be operated in an open ground, no barriers, no any interference. But in the practice, the remote light switch mode 0020114 will be hindered by trees, walls or other constructions, and will be exposed to some interference by other signals. Therefore, the actual distance may or may not reach 2000m.
The working distance of the remote controller for the remote light switch refers to the sensitivity of the wireless receiver when it receiving the signal and the capacity of the remote controller. The sensitivity of the wireless receiver for the remote light switch depends on the antenna.
So, if you want to have the longest distance, you may first choose a high power remote controller. When you want to control the devices outside the house or from a far distance, it is better to choose remote controller with external antenna.
Trees, water, cement or other constructions will all reduce the signal of the remote controller. You may set the wireless receiver on a higher place to get a better signal.
 
How to get the longest distance of the remote controller for the remote light :
First, choose the suitable remote light switch kits and its accessories to get a longest distance.
(1)Transmitter: you can choose a high power transmitter to get a longest distance.
There are some examples:
ModelWorking DistanceSize
CP-2500m (theoretical)135mm x 42mm x25mm
CB-21000m (theoretical)135mm x 42mm x25mm
CC-25000m (theoretical)135mm x 42mm x 25mm

(2)Wireless receiver: Normally, almost all the wireless receiver consists of their own internal antenna. You’d better choose the wireless receiver with external antenna. External antennas consist of magnetic sucker antenna (longer distance) and telescopic antenna (middle distance). According to the environment, choose the suitable external antenna for your receiver so that it can get a longest distance.
There are some examples:

Tips:
a) Stand the antenna on end;
b) Completely stretch the antenna.
By doing this, you can get a better signal, therefore, you can get a longest distance.
(3)The external antenna can be set on both receiver and transmitter.
 
Second, operate the remote light switch kit in a right way to make sure that you can get a longest distance.
  • The battery power of transmitter must be adequate and the battery voltage must higher than the theoretical level. For example, the battery voltage of transmitter is 12V, when the battery power is adequate, the voltage will higher than 12V, may be 12.1V or 12.2V.
  • The battery voltage of receiver must be adequate and must be within the working range. Using regulated power supply and choosing the good quality power adapter. If the receiver is using the storage battery, then the battery capacity must be high.
  • Don’t put the receiver in a metal box, because the signal weakens greatly by the metal. The solution is set an external magnetic sucker antenna outside the metal box.
  • When the wireless receiver cannot receive the RF signal from the remote controller, which means the working distance of the remote light switch may not reach the theoretical data. Then you can choose a signal repeater model 0010001(R-01) to solve this problem.
Apart from the above information we have mentioned, there is another important news we want to show you.
In the past, we only have CB series remote controller for the remote light switch, which working distance is 1000m. Now, we have CC series remote light switch for the remote light switch, its theoretical working distance can reach about 5000m, which is much longer than 1000m.
We also produce a new series of remote light switch kits. The working distance is 5000m.
These remote remote light switch kits have feedback function and two ways working mode.
With the feedback function, the remote light switch kits can let the user know whether he/she had already connected the remote controller and wireless receiver successfully in such a long distance.
Here is the principle of the feedback function for this remot light switch kit.
[Remote Controller]   <———
|                         
[Encode]

[Channel]                [Feedback]

[Decode]                       /
|                          /
[Wireless Receiver]     ———->
 
Two ways working mode of the remote light switch: When the wireless receiver gets the signal from remote controller, it will immediately send a return signal to the remote controller. When the remote controller receives the feedback signal from the wireless receiver, the remote controller will exude a buzzing sound like “D~” which means it receive the feedback signal successfully.
The wireless wireless for the remote light switch is waterproof case with waterproof connectors. The wireless receiver can be installed outdoors. They are also high power remote light switch kits, each relay output can work at maximum current 30A.
External magnetic sucker antenna for the remote light switch with 5meters cable, the antenna can be installed outside the building to get better working distance
The remote light switch kits can be used in agriculture automation, industry automation, and home automation. It can control products on land, water and air, especially in a long distance, such as business signs, motorboat, farm, pasture, offshore unmanned operation, field call, remote security alarm, unmanned aerial vehicle, etc.
