4G and 5G are both wireless communication technologies used for mobile devices, but there are several key differences between the two:
1. Speed: 5G technology is much faster than 4G, with data transfer speeds up to 10 Gbps, while 4G typically offers data transfer speeds of up to 100 Mbps. This means that 5G can support much more data traffic, making it ideal for high-bandwidth applications like video streaming, gaming, and virtual reality.
2. Latency: 5G has much lower latency than 4G, meaning that there is less delay between when data is sent and received. This makes 5G ideal for real-time applications like online gaming, remote surgery, and autonomous vehicles.
3. Coverage: While 4G is widely available in many countries, 5G coverage is still limited. 5G requires a denser network of small cell towers and antennas than 4G, which means that coverage is currently limited to certain urban areas.
4. Spectrum: 5G uses higher-frequency radio waves than 4G, which allows for faster data transfer speeds but requires more cell towers and antennas to provide coverage. The higher frequency also means that 5G signals have shorter range and are more easily blocked by obstacles like buildings and trees.
5. Security: 5G has more advanced security features than 4G, including stronger encryption and authentication protocols. This makes 5G more secure and less vulnerable to hacking and cyberattacks.
Many differences that can not be written in an answer for a question (as Lassaad Hedhili mention), also used frequency, technologies, 5G users requirements, quality of services, quality of experience, etc.
I recommend this book for you "6G Mobile Wireless Networks." Cham: Springer International Publishing, 2021, or the 5G version of it.
Greetings, the difference between the stated technology has to be viewed at two aspect, first at the aspect of networks and second at the aspect of antenna system. In terms of antenna system the difference between 4G and 5G will be MIMO antenna for 4G and Massive MIMO for 5G. The stated difference itself speaks for itself i.e. in terms of capacity improvement, data rate, reduced latency and so on. In addition the addage to 5G at the aspect to evade from the existing spectral crunch will be usage of mm wave spectrum.
The probable frequency bands that are proposed to be utilized in 5G are way higher than the previous cellular generations. For instance, 4G usually use sub-6 GHz frequency range, whereas frequencies such as 24.25 GHz, 54.60 GHz, and even 71 GHz frequency bands are considered to be incorporated in 5G.
The overall network architecture of 5G is much more sophisticated than 4G. Apart from offering higher data rate, throughput,and better QoS; 5G have introduced a technique called beamforming that is highly responsible for a better user experience.
Overall, 5G and B5G technologies have potentials to revolutionize the cellular networks although in most of the countries it is not fully established yet.
