1, 5G network refers to the mobile network 5G, which has not yet been commercially available 5G WiFi refers to the WiFi transmission frequency of about 5Ghz.
2, although 5g is faster, but also more requirements, the first is that the wireless network card can support 5g, which is not possible for general network cards.
Do not upgrade to 5g for the sake of speed, and then find that the network card is not supported and then replace the network card and bring trouble and waste of money.
3, with Qualcomm's crazy advertising and the recent release of various 5G mobile phones, it seems that 5G is getting closer and closer to the release. Because both
of them carry the word "5G", many friends will also have the question of whether "5G WiFi" and "5G communication" are connected, and there is no more reliable
answer.
The differences between 5gwifi and 5g networks are analyzed as follows:
The datasheet of 5G MIFI model M1 is as follows, getspeed is a company integrating industry and trade, and its factory in ZhongguoShenzhen has 14 years of production experience so far. If you need router, please feel free to contact the following contact information.
Using a portable WiFi router comes with numerous benefits. Here are some key advantages:
Personal accompanying scene:It can be used in all kinds of outdoor mobile office applications, such as: SOHO mobile office, business travel, outdoor live broadcast, drone inspection return, etc.
Outdoor entertainment scene:Such as outdoor watching movies, self-driving Internet, etc.
Home broadband access scenario: For example, MiFi can also be useful when users do not have easy access to broadband or live in an area with poor signal.
1.The two have different advantages
The biggest advantage of 4GHz is that it has strong penetration and spreads over longer distances. The advantage of 5GHz is that the output is stable and can support
the transmission of big data.
2.different scope of application
If it is far away from WiFi and there is a wall in the middle, 4GHz is preferred. If it is close to WiFi and does not move much, 5GHz is preferred.
Wi-Fi (pronounced: /? wa? fa? /, French pronunciation: /wifi/), also known as "mobile hotspot" in Chinese, is a trademark of the manufacturer of the Wi-Fi Alliance as a
product brand certification, is a wireless LAN technology created in the IEEE 802.11 standard. Because of the close relationship between the two systems, Wi-Fi is often
used as a synonym for the IEEE 802.11 standard. "Wi-Fi" is often written as "WiFi" or "Wifi," but these are not recognized by the Wi-Fi Alliance. Not every product that
matches IEEE 802.11 is certified by the Wi-Fi Alliance, and a relative lack of Wi-Fi certification does not necessarily mean that a product is incompatible with Wi-Fi devices.
IEEE 802.11 devices have been installed in many products on the market, such as: personal computers, game consoles, MP3 players, smartphones, tablets, printers,
laptops and other peripherals with wireless Internet access.
With the development of science and technology, people have higher and higher requirements for network speed, hoping to use ultra-fast network without delay. And now there are roughly two types of routers, one is 2.4G, one is 5G, what is the difference between the two? Is it based on the size of the number, the larger the number, the better the WiFi? Here is to give you the relevant knowledge.
1. What is Wi-Fi?
Wi-Fi is a technology that connects terminals such as personal computers and handheld devices (such as PDAs and mobile phones) to each other wirelessly. Can be simply understood as wireless Internet access, almost all smart phones, tablets and laptops
support Wi-Fi Internet access, is today's most widely used a wireless network transmission technology.
The full name of WiFi is Wireless Fidelity, which was originally a brand certification for the commercialization of wireless LAN technology. The first generation of WiFi technology standardized label 802.11, originally developed by the IEEE(American Institute of Electrical and Electronics Engineers) in 1997, mainly in order to enable different brands of wireless network products to achieve common and compatible, Wi-Fi is often regarded as the IEEE 802.11 standard synonymous term
Since 1999, IEEE has upgraded the 802.11x technical standard several times, during which there have been 802.11a, 802.11b, 802.11g, 802.11n and other versions, the biggest difference between these
versions is that the transmission speed continues to improve, and the signal coverage continues to expand. In order to facilitate promotion, some related manufacturers organized an industry alliance,
which was renamed the "WiFi" Alliance in 2000, and used WiFi as a trademark to promote wireless LAN technology.
The first generation of 802.11, developed in 1997, only operates at 2.4GHz, with a maximum of 2Mbit/s;
The second generation 802.11b, which only runs at 2.4GHz and up to 11Mbit/s, is being phased out.
Third generation 802.11g/a, respectively operating at 2.4GHz and 5GHz, the fastest 54Mbit/s;
Fourth generation 802.11n, can operate at 2.4GHz or 5GHz, 20 and 40MHz bandwidth up to 72 and 150Mbit/s;
The fifth generation of 802.11ac(commonly known as 5G WiFi) only operates at 5GHz.
(1) 5G has more available channels than 2.4G and less interference.
2.4G has a total of 14 available channels, each sub-channel width of 22MHz, adjacent channel center frequency interval of 5MHz, adjacent multiple channels have frequency overlap (such as 1 channel
and 2, 3, 4, 5 channels have frequency overlap), the entire frequency band only 3 (1, 6, 11) do not interfere with each other. 5G has a total of 24 channels, and 22 non-interfering channels are working,
which greatly exceeds the number of non-interfering channels at 2.4GHz. The 5GHz band is used less, only 149, 153, 157, 161, 165 these 5 (civil), radio interference is greatly reduced, and the quality of
the wireless network is greatly improved.
Generally speaking, we can think of the 2.4Ghz band and 5Ghz band as highways, and if we want to go on this road, we must abide by the rules of this road. Because the 2.4Ghz high-speed, not only the speed limit is only 60, and in addition to wireless WiFi, wireless mouse, keyboard, headphones, induction cooker and other wireless devices are used in this band, many WiFi common a channel will cause signal interference and lead to slow transmission rate. On this 5Ghz highway, not only the road condition is good, but also the speed limit reaches 200, which does not allow the road to meet the requirements, and there are not many cars eligible for the road, so there are very few cars on this road.
2.4G refers to the 2.4G to 2.4GHz wireless frequency; 5G refers to 4.9G-5.9GHz wireless frequencies (G here is not what we often say on the wide area network 3G or 4G network). The essence of both are electromagnetic waves, and according to the transmission law of electromagnetic wave propagation rate = frequency x wavelength, the biggest difference between 5G and 2.4G is that 5G is farther than 2.4G, but 2.4G has stronger anti-attenuation ability.
The reason why 2.4G feels more "through the wall" than 5G is actually because of the stronger diffraction ability of electromagnetic waves. Since the main mode of electromagnetic wave propagation is linear propagation, when encountering obstacles such as walls, it will produce penetration, reflection and diffraction. However, 2.4G has a lower frequency than 5G, and electromagnetic waves (network signals) have stronger diffraction ability and lower attenuation degree. Therefore, the statement "2.4G can penetrate the wall more than 5G" is problematic, and the correct summary should be "2.4G can encircle the wall more than 5G".
