5G is mainly to meet the needs of the mobile communication field, providing faster data transmission speed, lower latency and higher bandwidth to support more device connections and more complex applications. Wi-Fi, on the other hand, provides wireless network connections for homes, WIFI serial server businesses and public places, enabling people to connect to the Internet wirelessly and carry out online activities. Both are designed to provide faster, more stable, and more convenient wireless network connections to meet people’s growing network needs.
5G and Wi-Fi are two different wireless communication technologies, and there are essential differences in network connection methods, transmission speeds, and coverage areas.
The following will be analyzed from the following aspects:
(1) Different frequency bands and speeds 5G communication uses high-frequency radio waves, mainly in millimeter wave frequency bands and sub-millimeter wave frequency bands, and the bandwidth of 5G communication is relatively large, which can reach speeds of tens of Gbps; while Industrial Router/Gateway uses low-frequency radio waves, mainly in the 2.4GHz and 5GHz frequency bands. Today, the highest speed of the new generation of Wi-Fi 6 can only reach 9.6 Gbps.
(2) Different network coverage The coverage of 5G is wider than that of Wi-Fi. 5G technology uses smaller base stations and higher frequencies, which can cover a wider range and provide more stable signals. However, the coverage of Wi-Fi is relatively small, and generally it can only provide a stable signal within a range of tens of meters.
(3) Different stability The stability of 5G communication is better, and the signal is less susceptible to interference and blocking, while the stability of Wi-Fi communication is relatively poor, and the signal is easily affected by obstacles and interference.
(4) The number of connected devices is different. 5G can connect more devices. 5G technology adopts higher bandwidth and more advanced multi-user technology, which can support more device connections, and can also process a large amount of data traffic faster. . However, the number of Wi-Fi device connections is relatively small, and generally only supports dozens of devices.
(5) Security 5G network is more secure than Wi-Fi. 5G networks use more secure encryption, while Wi-Fi has some security holes.
(6) Electromagnetic wave radiation 5G network needs more antennas to cover a wider area, so it will generate more electromagnetic wave radiation. Wi-Fi has lower electromagnetic wave radiation than 5G.
(7) Different technical standards 5G is a brand-new mobile communication standard, and its technical standards are formulated by the International Telecommunication Union (ITU) and the Third Generation Partnership Project (3GPP); while Wi-Fi is based on the IEEE 802.11 standard Wireless LAN technology.
(8) Different application scenarios 5G is mainly used for mobile communications, providing high-speed data transmission and low-latency network services for mobile devices such as mobile phones and tablets; while Wi-Fi is mainly used for wireless local area networks in fixed Devices such as smart homes provide wireless connectivity services without the need for mobile
