Yes, the Redmi Note 14 Pro+ 5G supports High-order modulation.
For your reference, here is more information about High-order modulation:
1. High-order Modulation is a technique used in communication systems, including mobile networks like 4G and 5G, to increase the data transmission rate and improve the efficiency of bandwidth usage. It involves transmitting multiple bits per symbol, which enhances the data rate and overall network capacity;
2. High-order modulation increases the amount of data that can be transmitted over the same bandwidth, leading to faster download and upload speeds;
3. High-order modulation can make better use of the network's available resources by squeezing more data into the same transmission time, improving overall network performance;
4. In areas with weak signals or high interference, these modulation techniques may not work effectively, leading to data transmission errors and reduced performance.
