New iPhones' U1 chip has unique design and compatibility with other devices

They thought the odyssey of iFixit with 2019 iPhones was it over? Because the repair site decided to go even deeper into the dismantling: now they have focused their efforts specifically on U1, chip found in the new iPhones and responsible for emitting so-called ultra-wideband waves (which eventually will work in conjunction with speculated Apple Tags).

Dissecting the component, iFixit found that Apple is using its own unique design previously, it was suspected that the U1 was simply a chip from the manufacturer. Decawave (the DW1000) with the name changed, but apparently this is not the case.

The fact that the chip is designed by Ma itself, however, need not cause concern: Decawave itself issued a statement stating that the U1 is compatible with the company's solutions and any IEEE 802.15.4 standard sender / receiver. With that, we can expect the new iPhones to use the new chip to communicate with various types of third party accessories, and not only with the supposed "Apple Tags" that, however, will only be confirmed when (or if) Ma moves and reveal your plans in the area.

IFixit also analyzed some technical details of U1. The chip uses a much higher frequency spectrum than protocols like Wifi or the Bluetooth (two technologies that focus on a specific frequency); In addition, ultra-wideband technology works as its name implies on very wide 500MHz channels.

With this, we have a significant advance in signal speed and latency, as well as avoiding the notorious interference problems. The iFixit itself parallels that Wi-Fi and Bluetooth work like a small pipe transferring water from place to place with debris and rocks disrupting the flow; The ultra-wide band, on the other hand, uses several wider pipes to transfer water at a much higher speed and with no stones in the way.

All this technology just makes us ask: what are Apple's plans for U1 anyway? Sure, we already have the chips in the new AirDrop interface, and the Apple Tags should be presented soon, but will we just be there? The company could very well, as iFixit points out, use ultra-wideband to revive the iBeacon, Apple's (currently Bluetooth-based) technology for locating people in places such as shops, airports, and museums.

Beyond that, imagination is the limit we have the potential for good use of technology in smart locks, vehicles, furniture, augmented reality applications and a whole host of products and services. It is the hope that this invasion does not take long, therefore.
