1.) Understanding IR Blasters

An IR blaster is a small electronic device that emits infrared light to control various devices such as TVs, air conditioners, set-top boxes, and more. By using your smartphone as a remote control, you can turn on or adjust settings of these devices with the help of specialized apps. This capability is particularly useful for users who have smart home setups where multiple devices need to be controlled via their smartphones.

2.) Why Smartphones Lack Built-in IR Blasters?

1. Cost and Complexity

Adding an IR blaster to a smartphone increases its complexity and cost. Manufacturers must consider not only the hardware but also ensuring that it complies with safety standards, including emissions limits for IR light. The added component requires more space inside the device, which can be challenging in compact smartphones designed for portability.

2. Battery Life

The infrared LED used as a blaster consumes battery power. To maintain an acceptable battery life, manufacturers often opt to include this feature only in high-end models where consumers are willing to pay extra for additional functionality. This way, they can balance the cost and benefits between different model lines.

3. Regulatory Standards

Smartphones sold globally must comply with local regulations regarding emissions from LED lights. These standards vary by region, adding another layer of complexity in designing a device that works across borders without violating any laws.

4. Design and Aesthetics

The placement of an IR blaster on the smartphone would affect its design aesthetics. Some users might find the presence of an IR blaster unattractive or intrusive due to its size and location within the phone's frame. Manufacturers must balance functionality with user experience when deciding where to place components inside the device.

3.) Alternatives for Controlling Infrared Devices

1. Smartphone Apps

There are several apps available in app stores that can act as remotes for various devices, including TVs and set-top boxes. These apps use your smartphone's Wi-Fi or Bluetooth connectivity to control the device they emulate a remote for. While not quite as direct as using an IR blaster, these apps provide a practical workaround for many users.

2. Smart Speakers and Virtual Assistants

Voice-controlled devices like Amazon Echo and Google Home can be paired with smart home technology platforms that support third-party integrations. These platforms often allow you to control various electronics through voice commands or app interfaces, effectively turning your smartphone into a remote by proxy.

3. Hardware Remote Controls

Many modern TV models come with built-in apps that users can download onto their smartphones for remote control functionality. If your device is compatible and you have the app installed, this serves as an effective solution without needing a traditional IR blaster in the phone itself.

4.) Conclusion

While it's true that most smartphones do not include a built-in IR blaster, there are several ways to achieve similar results using other technologies such as smartphone apps, smart speakers, or even dedicated remote controls for your devices. Understanding these alternatives can help users enhance their smart home experience without being limited by the absence of an infrared emitter in their handset.
