DUAL BAND WIFI ROUTER 2.4 GHz or 5 GHz : What wifi band to use?

The 2.4 GHz wifi bands, 5 GHz wifi bands you have probably already seen these numbers and put a question mark on what they represent. They actually refer to two different bands that your wifi network can use to get a signal. The main differences between the two frequencies are the distance travelled by your data and their speed, the most important being the speed.

What is a Dual band wifi and Tri band  wifi router?

The good news is that the majority of recent routers use dual- or tri-band technology. A Dual band wifi router uses both the 2.4 gHz and 5 gHz bands to broadcast its network, offering you two networks to get the most out of both bands (range with 2.4 gHz and speed with 5 gHz). Two types of Dual-band routers exist:

Selectable Dual Band: A selectable Dual-Band WiFi router offers a 2.4 gHz network and a 5 gHz network, but you can only use one at a time. A switch on the router box will allow you to easily switch from 2.4 gHz to 5 gHz.
Simultaneous dual-band: A dual-band WiFi router broadcasts two WiFi networks simultaneously: a 2.4 gHz and a 5 gHz. Allowing you to choose.

Under the conceptual conditions, 2.4 GHz Wi-Fi will support up to 450 Mbps or 600 Mbps, depending on the router class, while 5 GHz Wi-Fi will support up to 1,300 Mbps. The 2.4 GHz band provides coverage over a longer range, while the 5 GHz band provides lower coverage.
The explanation for a lower range in the 5 GHz band is that higher frequencies have difficulty penetrating solid objects, such as walls and floors. However, low frequencies allow data transmission much faster than low frequencies. Thus, with the 5 GHz band, you can download files faster than when using the 2.4 GHz band.

Interference from other devices on the wifi band.

The speeds of a wifi connection on a particular frequency band are also affected by interference from other devices. Many wifi enabled technologies and household devices use the 2.4 GHz band, such as microwaves, cordless phones and garage door openers. When several devices try to use the same radio space, this results in an overload because these devices add noise to the media, which reduces the speed of wireless networks.

The 5 GHz band is generally less overcrowded than the 2.4 GHz band because it is used by fewer devices, mainly because it has 23 channels, while the 2.4 GHz band has only 11 channels. However, the radar and military frequency is also 5 GHz and can therefore be slightly disturbed. Many countries require that wireless devices working in them must support dynamic frequency selection (DFS) and transmission power control (TPC).

Which WiFi band should you use?

The choice depends a lot on the purpose of the group. The need for faster speeds makes 5 GHz a better choice than 2.4 GHz. If wireless range is more important to you, 2.4 GHz is the best choice. If many devices use 2.4 GHz and you experience interference or connectivity problems, the 5 GHz option is the option.

How do personal devices connect to wifi bands?

Note that, while a wifi network can use both bands, your personal devices such as smartphones, tablets and laptops only connect to one radio band at a time. Each device has basic rules on which it decides on the connection of the tape. Your phone may connect to the 2.4 GHz band, while your laptop may connect to the 5 GHz band. This way, the device will decide which band it will use to connect.

For devices that only support the 2.4 GHz band, they will automatically connect to that band. Dual band wifi devices that support 2.4 GHz and 5 GHz frequencies automatically select a band based on different factors, such as signal strength.

Can you dictate a wifi band for your device?

Yes, depending on the device. Older devices are locked on the 2.4 GHz band, but there are Android devices that allow users to specify the band to be used to connect. All you have to do is follow a simple procedure; open the settings menu of your Android device, press wifi, then tap the three dots in the upper right corner, tap Advanced > Wifi frequency band, select the desired radio band.

Hey in this blog we mainly maintain the conversation on wifi and everything that goes with it. So you will find there networks, a wifi zone or a public wifi in your surroundings, as well as protection protocols, security and tutorials on configuring and maintaining your wifi network !
