Communication Range of Infrared Product

This topic describes how to test the maximum communication range of an infrared product in practice.

Test principle

After pairing the infrared product indoors, increase the distance between the infrared product and the electrical appliance, meanwhile, keep testing the device with the Smart Life app.

Since different placements result in different communication ranges, it is required to test the maximum communication ranges in different directions and angles of the infrared product on the same horizontal plane.

Test condition

Test device

• An infrared product
• An electrical appliance with an infrared function (using an air conditioner control board as an example)
• A mobile phone (with the Smart Life app)
• A router

Test environment

An unobstructed indoor environment.

Test process

1. Complete the pairing of the infrared product.

2. Place the infrared product and the air conditioner control board on the same horizontal plane with a ground clearance of 1 meter.

3. Keep increasing the distance between the infrared product and the air conditioner control board. Meanwhile, keep controlling the device with the Smart Life app. It is shown as follows.

   

4. Determine the maximum communication range.

   Reach a point at which the control success rate is approximately 20% and beyond which the control loses. The distance between the point and the electrical appliance is considered as the maximum communication range.

5. Change the product angle as shown below and repeat the steps 3 and 4. Test the maximum communication ranges of each side and angle.
