In the case of last year’s iPhones, they differ in terms of Wi-Fi support.
Cheaper models are compatible with Wi-Fi 6, while the Pro line models can use Wi-Fi 6E.
Meanwhile, Apple’s website has information about the new models and the supported network. It turns out that both the cheaper models and the Pro versions are compatible with Wi-Fi 7.
This will allow devices to simultaneously send and receive data on the 2.4 GHz, 5 GHz, and 6 GHz bands, which will translate into faster speeds, lower latency, and a more stable connection. Additionally, the maximum data transfer could be 46 Gbps. For comparison, Wi-Fi 6E has a maximum of 10 Gbps.
