Entry to a lined cellar looked like entering a type of gate. The sterile white room was lining up with foam towers in the form of a pyramid. Intersection between the registration studio and the ice torture room directly from the Elsa Castle from the Frozen movie. I looked down in my country phone: No bars. In the depths of Apple test laboratories, you are officially out of the network.
I was reviewing Smart watches Almost a decade ago, but I haven’t stopped asking how to actually communicate on Apple Watch. I saw him switch smoothly between my phone and Wi-Fi, paying things without hinting from the cellular signal, and planning my work even when I forget my phone at home. I have taken a foregone about how this invisible communication network works behind the scenes, and according to Apple, this is a lot of design.
From Wi-Fi and GPS to Bluetooth and GNSS, now 5G and satellite connection on Apple Watch Ultra 3, a continuous current of wireless signals move inside and outside the hour, making it a mark. The antennas and devices should be smoothly woven into the device’s tissue from the early design stage-far from view-and then they were tested in the scenarios of the real world to ensure that nothing interferes with the signals that enter or outside (not even your arm).
When opening its laboratories doors, Apple looked bent to shed light on the strict testing process that brings a product like Apple Watch to Market. Since the best -selling smart company in the world, the company has developed the Apple Watch as the standard of industry, which means that each indication should work in an intended manner. This type of test is not just quality control; This is the way Apple pushes the limits of what can fit into a small device, especially when competitors such as Samsung and Google are closed in its features and share in the market.
After getting a rare peek into the contact test laboratories where the Apple Lest, which indicates the stress performance test, I don’t think I can never wear the Apple Watch watch without thinking about the carefully designed sequence to design the product and test it that makes this connection possible.
Watch this: New Apple watches raise our blood pressure with its new features
Anechoic radio performance test
Apple carries out a lot of contact tests in custom facilities near its headquarters in Cuperno, California. Our tour began in one of these unwanted buildings, usually outside the audience, as we took off through a maze of black sections that I imagine were hundreds of other tests that we were not allowed to see. We got to what appeared to be a pigeon cellar lining up with blue foam mutations, such as a slightly threatened sound booth.
Inside the Anechoic room, Apple tests an antenna performance using Apple Watch Series 11 installed on a fake arm.
This is what Apple calls the ANCOC Radio Room: a fully silent radio environment that prohibits external signals. In the center was Apple Watch 11 series On an arm -shaped black mountain, it mimics how the human body can interfere with signals. The black theme ring shaved the room, measuring the quality of the clock antennas with different cell teams and different Wi-Fi teams. Once closed, the room is designed to remove any external intervention.
Apple uses this room to test everything from early preliminary models from hours to ready -to -produce models, perform the correct antenna for each cellular range and area and check the health of every one hour starts from the production line.
The Apple Watch Series 11 and Ultra 3 also uses a new algorithm for antenna diversity, which begins to combine the two systems of the two systems per hour when the signal becomes weak, which enhances connection while maintaining energy.
Add in the human variable
But the primary rubber model does not make the perfect position for the rest of our bodies full of meat, which can often create an overlap of radio signals that enter and out of our hour. To the following laboratory for that. The deepest at the bottom of the maze of the departments, we encountered another slightly larger cellar. The bright white walls stood in a sharp contradiction with the mood of the previous dark room. These preliminary models of the cut ends inside were not supposed to include actual people, and to test how the body itself could affect the air signals.
In addition to the torture room (perhaps watching a lot of films) it was a chair with a modern white arm with a bright red pillow that seemed outside the place (or perhaps perfectly suitable) in this hospital -like environment. Ensure that actual tests last only a few minutes (so, it’s actually a torture room). But I was still hesitant because I sat on the round chair to give it a craftsman myself, the white foam towers are hanging for me like snow. After all this accumulation, the chair weave amazingly slowly and nothing like trying the Disneyland cup that I was photographing in my head.
Engineers use this room to study the actual human body communication on Apple Watch.
The Apple engineers allow to draw a map of how the human body prevent or distort the signal from different angles. This is especially important for Apple Watch Ultra 3 and its new satellite connection, which depends on a directional antenna designed to communicate with satellites that revolve 800 miles above the ground at 15,000 miles per hour.
Outside of the room, engineers monitors the intensity of the reference that the watch receives through a heat map (simulation) of the signal of the signal from the screen while the test shift.
Exit from the network: GNSS Room
The last room, which was placed at the level of the basement, was the largest of the three. Once I entered the huge room, I saw cellular bars on my phone starting to decrease until I disappeared completely when I reached the center. This was the global satellite system simulator for global navigation, which has an area of 15 meters, which could deceive a view of believing that it is anywhere in the world. Today, I was moved somewhere in the depths of Denali National Park in Alaska.
This room can deceive Apple Watch to think anywhere in the world (even outside the network) to test the site’s accuracy with the satellite connection.
He lacked foaming ice walls in the other two rooms, but instead, lined up with black towers wandering from the ground and surrounded by huge circular air rings stacked towards the ceiling.
In the middle, Apple Watch Ultra 3 sat on a fake black holder, indicating a makeup point outside the network on the map. The room can re -create micro -satellite engineering for anywhere on the ground, allowing Apple to test the accuracy of the watch, locate your location. This type of accuracy is very important SOS emergency via satelliteBut it also provides non -emergency features such as sharing your site through Find My network when you are outside the network.
Invisible magic that makes everything work
According to Apple engineers, this test is a sensitive dance for creating, breaking, repeating and re -testing, which may take a year to complete. Each step pushes the limits of what can be suitable within the delicate curved body of the Apple Watch 11 series without prejudice to its design or battery life. Apple will never say that, but I couldn’t imagine that somewhere beyond those black sections, they are already putting preliminary models for the next two army from Apple Watch through their steps.
Now, after I saw the lengths that Apple goes behind the closed doors, I know that I will feel a little more confident the next time I am outside the network, knowing that it is somewhere in a hidden laboratory in Cubino, Apple engineers have already tested this place.
