What’s the difference between 2.4 GHz & 5 GHz Wifi?

The main differences between 2.4 GHz and 5 GHz Wi-Fi can be summarised in terms of speed, range, and interference:

2.4 GHz Wi-Fi

• Range: Covers a larger area; better at penetrating walls and obstacles.
• Speed: Slower compared to 5 GHz due to lower frequency.
• Interference: More prone to interference from other devices (e.g., cordless phones, microwaves) because it shares the crowded 2.4 GHz band.

5 GHz Wi-Fi

• Range: Shorter range; struggles to penetrate walls and obstacles.
• Speed: Faster speeds due to higher frequency and more available channels.
• Interference: Less prone to interference, as it operates on a less crowded band.
