On April 1, Apple officially pushed the iOS 18.4 update to iPhone users. This update not only brings an upgrade to Apple Intelligence, but also adds support for 5G-A networks.5G-A stands for 5G-Advanced, which is a further evolved version based on existing 5G technology. It can also be called enhanced 5G or 5.5G. It is not a complete replacement of 5G, but a comprehensive upgrade of its performance, aiming to achieve faster data transmission rates, lower latency, more stable connections, and a wider range of application scenarios.

At the technical level, 5G-A introduces many innovations and has the following advantages:

Speed ​​boost:The theoretical peak rate can reach 10Gbps, and the downlink speed is 10 times faster than standard 5G.

Low latency:Latency is reduced to milliseconds, which is suitable for high-demand scenarios such as industrial Internet and smart cities.

Stronger connectivity:Supports simultaneous access of more devices and remains stable in dense environments.

Multi-carrier aggregation:Improve network stability and transmission rate through three-carrier aggregation technology.

According to actual testing by users of the previous beta version, when the 5G-A network is activated, the iPhone's measured speed can reach 1400Mbps, far exceeding the traditional 5G network.

In addition, the official version of iOS 18.4 has also optimized functions such as photo album and control center. The Photos app now has a new gallery view filter that allows users to show or hide items that are not included in albums or synced from Mac/PC, and supports reordering items in media types and utility collections.
