2.4 GHz and 5 GHz are two bands, which do not affect transmission speed.
Many netizens may ask if 5GHz in wireless routers is faster than 2.4 GHz. Just like in mobile communications, mobile 4G is faster than mobile 3G, and 3G is faster than 2G. In fact, the 5GHz of wireless router refers to one band. 2.4 GHz is the same. There is no difference in transmission speed between the two bands. They are more like two lanes and do not affect each other. In mobile communication, 4G and 3G refer to the fourth and third generation communication technology, so there are obvious differences in speed.
Why launch 5GHz band at the same speed?
The main reason is that there are too many wireless devices in the 2.4 GHz band. Although there are about 11 channels in the 2.4 GHz band, with the popularity of various IT devices, such as iPad, mobile phone, PC, game console and so on, the throughput value of multiple devices decreases seriously when they are used at the same time. Secondly, the microwave oven, Bluetooth and wireless mouse also use 2.4 GHz band, which will interfere with other connecting devices.
Since the original road is too congested, a new road will be built to solve the congestion problem, which is the main reason for the appearance of 5GHz band. However, there are not many devices working in the 5GHz band, and the 5GHz channel is several times more than the 2.4 GHz channel, so it can solve the congestion problem well.
The 5GHz band also has its drawbacks
The first is that there are fewer devices to support. Wireless routers support 5GHz, but your mobile phones and tablets don't necessarily support 5GHz bandwidth connections. The second is that the penetration is slightly poor, the higher the frequency, the worse the penetration, and the wall penetration capacity is 2.4 GHz worse than the same period of last year. Replacing the antenna can solve the problem. In addition, it should be emphasized that the current dual-band routers mostly support 2.4 GHz and 5 GHz at the same time, so even if your device does not support 5 GHz or 5 GHz signal is not good, it can still connect to 2.4 GHz band.
On the Relation between Frequency Band and 802.11
802.11n/a/ac/g/b is actually a wireless local area network standard formulated by IEEE. There are dozens of kinds. The most common electronic products are 802.11n/b/g, 802.11a and 802.11ac. And the important reference standard to distinguish these 802.11 is the working frequency band. For example, the main working frequency band of 802.11n/b/g is 2.4 GHz, while the main frequency band of 802.11a/ac is 5 GHz. At present, almost all devices with Wifi support 802.11n, or 2.4 GHz working frequency band. So you just need to remember that if your phone, tablet or wireless routing supports 802.11ac, you can determine that it supports 5GHz bandwidth connections.
