What Is Dual Band WiFi?
Briefly, dual-bandWi-Firefers to wifi that has two radio frequencies (bands), 2.4 GHz and 5 GHz.
Therefore, WiFi routers transfer data over the 2 bands are calleddual band WiFi routers.
What Does Dual Band WiFi Mean?
Dual-band Wi Fi means wifi that generates by dual-band WIFI routers.
A dual band Wi-Fi router broadcasts both 2.4 and 5 GHz audio frequencies from the same unit.
There are two kinds, selectable and simultaneous, dual band wifi routers.
Selectable Dual-band Wi-Fi Router
it’s possible for you to only use one frequency at a time.
So read it carefully.
It is created to mitigate connection congestion.
A tri-band wifi router is helpful for handlinghigh-resolution videos(e.g.
4K videos), web link-intensive online games, etc.
Single Band vs Dual Band WiFi
Since there is dual-band Wi-Fi, there is single band WiFi.
Whats Single Band WiFi?
Actually, the single-band WiFi is much earlier than the dual band Wi-Fi.
It can penetrate solid objects like walls with little signal loss.
Thus, you’ve got the option to keep astrong Wi-Fi connectionwhen you arent close to the router.
2.4 GHz WiFi vs 5 GHz WiFi, the former provides fewer channels than the latter.
So, the 2.4 GHz band is more crowded and slower than 5 GHz band.
WiFi vs Bluetooth: what is the difference between them?
Read this post and you’ve got the option to know some details about WiFi and Bluetooth.
Also, the maximum speeds provided by 2.4 GHz are usually less than 100 Mbps in real usage.
Equipped with 2 audio bands, the dual band routers are able to deal with more traffics.
Below is a table comparing some common aspects of dual-band and single-band Wi-Fi routers.
The former has all the features that the latter has as well as avoids the disadvantages of the latter.
As for price, Wi Fi dual-band router is much more expensive than single-band router.
Dual Band WiFi Adapters
Dual-bandWi-Fi web connection adapterscontain both 2.4 GHz and 5 GHz wireless radios.
It is similar to dual-band routers.
In the early days of the wifi system, some laptop WiFi adapters supported both 802.11a and 802.11b/g radios.
Thus, the laptop could connect to both home and business networks.
Cell modems switch between different bands.
Yet, they dont support simultaneous dual-band connections.
