WiFi Adapter: What is the difference between 2.4G and 5G?

When purchasing or using all Maxesla WiFi Adapters, you will see 2.4G (2.4GHz) and 5G (5GHz).

So what's the difference between them? Under what circumstances, frequency should be chosen?

This blog will answer your appeal questions.


What are 2.4GHz and 5GHz of WiFi Adapter?

2.4GHz and 5GHz usually refer to frequency bands. WiFi devices typically communicate with each other by transmitting WiFi signals on the 2.4GHz and 5GHz radio frequency bands.

What is Dual Band WiFi Adapter?

A Dual-band WiFi adapter is a WiFi adapter that supports both 2.4GHz and 5GHz bands.

There are two types of dual-frequency:

①Optional dual frequency: two frequency bands 2.4GHz and 5GHz, select one of the frequency bands to use.

②Synchronous dual frequency: 2.4GHz and 5GHz broadcast at the same time.


WiFi Adapter 2.4GHz and 5GHz Band Comparison

Standard 2.4GHz 5GHz
Speed (Max) 400-600M 1300M
Link Range 20m 15m or less
Radio Interference YES NO
Penetration Ability Good General






What are the advantages and disadvantages of WiFi adapters 2.4G and 5G of WiFi Adapter?

2.4G WiFi Adapter

Advantages: 2.4G signal frequency is low, the attenuation is small when it propagates in the air or obstacles, and the propagation distance is longer;

Disadvantages: At present, most devices use the 2.4G frequency band, and the interference is large in places with many users.


5G WiFi Adapter

Advantages: 5G signal bandwidth is wider, the wireless environment is relatively clean, less interference, stable network speed, and can support higher wireless rates.

Disadvantages: The 5G signal has a higher frequency, the attenuation is greater when it propagates in the air or obstacles, and the coverage distance is generally smaller than that of the 2.4G signal.


Which is a better WiFi Adapter 2.4G or 5G connection?

5GHz is very suitable for high-definition video streaming and lag-free online games, suitable for some applications that require high network speed and latency, such as downloading, voice, real-time games, etc. 2.4GHz Wi-Fi is suitable for normal use, such as web surfing, music, online chat, etc.
