There's a gesture a whole generation learned without being taught: hold the remote up, aim it at the TV, and if nothing happens, wave it around a bit and click harder. That's the infrared era. You were literally shooting a beam of invisible light at a sensor and hoping your aim was true.
It worked, mostly. But it had rules. Point roughly at the TV. Don't block the sensor. Don't sit at too sharp an angle. Stay within range. We accepted all of that because there wasn't an alternative. Now there is, and once you've used it, going back feels faintly ridiculous.
What IR actually made you do
Infrared — the tech in every old clicker — works like a TV remote flashlight. The remote flashes a coded light, a sensor on the TV reads it. That's why line of sight matters: block the light and the message never arrives.
Which is why the old remote had opinions about where you sat, whether the coffee table was in the way, and whether you were pointing it at the TV or vaguely at the ceiling. Miss the sensor and nothing happened.
Wi-Fi doesn't care where you're pointing
A Wi-Fi remote sends its commands over your home network instead of a beam of light. The TV is on the network. The phone is on the network. The command travels between them the same way a message travels to any device in your house — no aiming required.
The practical difference is bigger than it sounds:
- Point the phone anywhere. At the floor, at your lap, at the wall behind you. Doesn't matter.
- Sit anywhere in the room. Behind the TV, off to the side, in the next room even.
- Put something in front of the TV. A blanket over the sensor changes nothing.
Your Android TV already speaks this language over Wi-Fi, so a phone app like TV Remote for Android just talks to it directly — no line of sight anywhere in the chain.
And it does things IR never could
Line of sight is only half the story. An old IR remote was a fixed set of buttons — whatever the manufacturer molded into the plastic, that's what you got. A Wi-Fi remote on a phone is a screen, so it can be more.
It has a full keyboard for typing searches and passwords, which an IR remote handled with that dreadful on-screen letter grid. It has voice, so you can just say a title. It can show app shortcuts that jump you straight into Netflix or YouTube. The IR blaster couldn't dream of any of that — it was born to send button presses and nothing else.
Infrared did one job for forty years. It's allowed to retire.
Where IR still hangs on
To be fair, infrared isn't extinct. It's simple, cheap, and needs no network, which is why it's still in cheap universal remotes and some older gear. If your setup has no Wi-Fi, IR is what you've got. No shade there.
But for a modern Android TV or Google TV sitting on your home network, the calculus flipped a while ago. Wi-Fi control is more capable, more forgiving, and already living in your pocket. The point-and-pray days were fun in a nostalgic way, but nobody's actually asking to aim their remote again.
