Write the advantages and disadvantages of Infrared wireless technology.

The advantages of Infrared wireless technology are as follows:

1. It has low power consumption.
2. Infrared components are less expensive.
3. It is more secure than radio-frequency signals.
4. Direct line of sight requirement of Infrared enhances its security and minimizes interference, making it suitable for short-range, point-to-point communication.

The disadvantages of Infrared wireless technology are as follows:

1. It has limited range of approx 5 meters and it cannot penetrate walls or other obstacles.
2. It works only in direct line of sight between the transmitter and receiver. Even the smallest obstruction will disrupt communication.
3. Infrared communication can take place only between two devices at a time limiting its use to control multiple devices.
4. It has relatively low data transfer speeds compared to technologies like Bluetooth or Wi-Fi.
5. Bright ambient light, including sunlight and strong artificial lighting, can interfere with infrared signals and degrade the quality of communication.
