After its release, many users noticed a change at the bottom of iPhone XS Max and XS. Instead of two symmetrical speaker grilles and microphones like on iPhone X, there's now an antenna cut.

This antenna cut has drawn criticism for its perceived lack of elegance on the iPhone. However, few are aware that behind this cut lies an extremely sophisticated technology from Apple. Let's delve into this technology.
Introducing the New Signal Reception Antenna
Apple has implemented groundbreaking signal reception technology on the antenna, significantly enhancing the signal reception capabilities of iPhone XS Max and XS. Additionally, it is supported by high-bandwidth technologies such as 4x4 MIMO, QAM, and LAA, with 4 signal reception antennas, improving both quality and transmission speed by a significant margin.

The Results
The support for 4x4 MIMO allows simultaneous connection through 4 network antennas. Theoretically, network speeds, including mobile and Wi-Fi networks, on iPhone XS Max are expected to be twice as fast as on iPhone X. Though real-world performance may not match theoretical expectations, measurements show Wi-Fi speeds up to 45% faster and mobile LTE speeds up to 77% faster compared to the previous generation.

Promising Future Ahead
These are the tests conducted based on current Wifi and LTE infrastructure, while Apple's technology implementation may better align with future speed standards. As Wifi MIMO standards become widespread, we'll likely see even more robust wireless network connections on iPhone XS compared to now.

To achieve all these advancements, Apple had to compromise on one minor feature: symmetry at the bottom edge. Who needs two balanced speaker grilles when you have the world's fastest Wifi and LTE speeds, right? What are your thoughts on Apple's choice? Feel free to leave your comments below.
