What are the differences between 2.4G and 5G bands of routers

At present, many new wireless routers have dual-frequency to do the selling point, the popular Route 2, millet routers are supported dual-frequency, where the dual-frequency refers to the 2.4GHz and 5GHz, then 2.4GHz and 5GHz routers What is the difference? What are the advantages and disadvantages of 2.4GHz and 5GHz routers?

　　2.4GHz and 5GHz are two bands without affecting transmission speed.

Many netizens may ask the wireless router in the 5GHz is faster than 2.4GHz? Just like mobile traffic 4G faster than mobile 3G, 3G faster than 2G. In fact, the wireless router 5GHz refers to a frequency band, 2.4GHz the same, two bands do not exist transmission speed difference, they are more like two lanes, do not affect each other. The 4g,3g in mobile communication refers to the fourth generation, the third generation of communication technology, so there are obvious differences in speed.

　　Why do we have to launch the 5GHz band?

The main reason is that there are too many wireless devices in the 2.4GHz band, although the 2.4GHz frequency band can accommodate about 11 channels, but with the popularity of various it devices, such as the ipad, mobile phones, PCs, game consoles and so on are used in this band, resulting in the use of multiple devices at the same time, the throughput value seriously decreased. Second, microwave ovens, Bluetooth, wireless mouse also use the 2.4GHz band, will also interfere with other connected devices, as shown in the 2.4G congestion:

　　5GHz bands also have drawbacks

The first is the support of less equipment, wireless router support 5GHz, but your mobile phone, flat does not necessarily support the 5GHz band connection. The second is a slightly poor penetration, the higher the frequency of penetration, the ability to penetrate the wall 2.4GHz, a replacement antenna can solve the problem. Also need to emphasize that the current dual-band routers mostly support 2.4GHz and 5GHz work at the same time, so even if your device does not support 5GHZ or 5GHz signal is not good, can still connect the 2.4GHz band.

　　About the relationship between band and 802.11

802.11n/a/ac/g/b is actually an IEEE established wireless local Area network standards, the type of up to dozens of kinds of electronic products, the most common is 802.11n/b/g,802.11a,802.11ac. The difference between these 802.11 important reference standards is the working band, such as 802.11n/b/g main working band is 2.4GHz, and the main frequency of 802.11A/AC work is 5GHz. Almost all WiFi-enabled devices now support 802.11n, or 2.4GHz, working frequencies. So just keep in mind that if your phone, tablet or no line is supported by 802.11AC, you can determine that it supports 5GHz band connections.

At present, dual-frequency router is indeed a big selling point, after all, a more than one frequency band a choice, small series that old equipment with 2.4G, new equipment with 5G, what do you reader?
