Popular protocols include Wi-Fi, Zigbee, and Z-Wave. These signals can pass through walls and obstacles. They offer flexibility and ease of installation without wires.
Infrared Communication
Infrared (IR) communication uses light waves just below visible red light. Many remote controls use IR to send commands to devices. It requires a direct line of sight between devices. IR is simple and low cost but has limited range. It is ideal for controlling TVs, air conditioners, and other appliances in the same room.
Power Line Communication
Power line communication (PLC) sends data through existing electrical wiring. Devices communicate by modulating signals over power cables. This method avoids extra wiring and works well in buildings. PLC can cover the whole house using the electrical grid. It is useful where wireless signals face interference or weak reception.
