A brief comparison of LTE and 5G wireless technologies [Copy link]

LTE and 5G are two different wireless communication technologies that differ in speed, latency, capacity, coverage, and device compatibility.
LTE, or Long Term Evolution, is a 4G cellular network standard based on OFDMA, developed and released by the 3GPP organization. Its main purpose is to improve the air access technology of 3G, providing higher data rates and lower latency. LTE supports a maximum downlink rate of 100Mbps and an uplink rate of 50Mbps, with lower network latency. It operates in two modes, frequency division duplex (FDD) and time division duplex (TDD), of which FDD is the main mode. The spectrum of LTE ranges from low-frequency 700MHz to high-frequency 2.5GHz, supporting a variety of bandwidths from 1.4MHz to 20MHz.
5G, or the fifth generation of mobile communication technology, is the leading technology for the next generation of mobile communications. Compared with LTE, 5G has higher speed, lower latency, greater network capacity, and wider coverage. 5G can reach speeds of up to 10Gbps and support more online users and devices at the same time. Its latency is less than 1 millisecond, which is a significant improvement over LTE's 10 milliseconds. 5G uses millimeter wave high and low frequency bands for communication, supporting a larger bandwidth up to 100GHz. At the same time, 5G uses new network architectures and technologies, such as cloud networks, edge computing, and network slicing, to achieve higher performance and better services.
LTE and 5G differ in the following five aspects:
Different standards: LTE is an upgraded version of the 3G network, and 5G is an upgraded version of the 4G network.
Different speeds: LTE can reach a maximum speed of 100Mbp/s, while 5G can reach a maximum speed of 10Gbp/s.
Different technologies: LTE uses two standards, TD-LTE and FDD-LTE, while 5G uses two standards, SA independent networking and NSA non-independent networking.
Different frequency bands: LTE's frequency band is 1.8GHz-2.4GHz, while 5G's frequency band is 2.4GHz-3.6GHz.
Different scope of use: LTE is mainly used in mobile devices such as mobile phones, laptops, tablets, etc., while 5G is mainly used in IoT devices such as mobile phones, tablets, laptops, smart watches, smart glasses, smart homes, etc.
Different networking methods: LTE's networking method is FDD-LTE, while 5G's networking method is SA/NSA. In addition, 5G networks have the characteristics of higher spectrum bands, faster transmission speeds, and smaller network delays.
In general, LTE and 5G have significant differences in speed, technology, frequency bands, scope of use, and networking methods. Although LTE is still a powerful network in modern mobile communication technology, 5G is the core form of the next generation of mobile communications, with higher speeds, lower latency, greater capacity, and wider coverage. As 5G matures and becomes more popular, it will become an important driving force for future mobile communications.
