Two of the main bands used for Wi-Fi are 2.4Ghz & 5Ghz.
Here’s how they differ,
2.4Ghz – Best for use where usage is limited to surfing, chat, video streaming etc.
- Most widely used band.
- IEEE 802.11b,g & n is associated with 2.4Ghz band. It carries 3 non-overlapping channels i.e channel 1,6 and 11 which provide better wireless performance compared to other channels.
- Although this is a widely used band, it is prone to interference which causes lags and drops in performance when used closed to other devices which use the same band s.a microwave ovens or cordless phones.
- 2.4Ghz can be used to connect larger distances because it has a higher range compared to 5Ghz.
5Ghz – Best for use where usage is heavy s.a online gaming, cloud computing, heavy downloads, point to point bridging etc.
- Not as popular as the 2.4Ghz.
- IEEE 802.11a & n and the latest 802.11ac is associated with 5Ghz band. 802.11ac is the fastest 802.11 standard with speeds over 6Gbps. It has 23 non-overlapping channels and provides better performance than 2.4Ghz.
- 5Ghz is not much prone to interferences as 2.4Ghz. Hence its always considered over 2.4Ghz where performance is required.
- 5Ghz has shorter range compared to 2.4Ghz.
