The 2.5G frequency used by Wi-Fi can send far distances. However, it is not possible to send a lot of data with standard modulation of 2.5G frequency (BPSK~64QAM).
Although the reach is short at 5G frequency, a lot of data can be sent with standard modulation (BPSK~256QAM).
What is the difference between 2.5G frequency and 5G frequency used in Wi-Fi?
