Today we are going to discuss a controversial topic: In the Wi-Fi frequency band, is 2.4GHz or 5GHz more worthy of choice? I specially prepared a small experiment, hoping to use everyone's experience and opinions to unveil the veil of this hot topic. Experimental project: 2.4GHz Wi-Fi modules. 5GHz Experimental steps: Equipment preparation: You need a device that supports dual-band Wi-Fi (such as a laptop, a smartphone), and a Wi-Fi router that supports dual-band. Experimental environment: In the same test environment, first connect to the 2.4GHz frequency band, and record the speed, stability and coverage. Switch Bands: Connect the device to the 5GHz band and also record speed, stability and coverage. Data comparison: Compare the experimental data in different frequency bands to see which frequency band performs better in your test. Experimental parameters: Speed: Perform a speed test on both frequency bands, which can be measured using an online speed test tool or by downloading a large file. Stability: Observe the stability of the connection, whether there is any drop or delay. Coverage: In different frequency bands, move the device to different locations to see if the signal coverage changes.
