4G
4G is the marketing name for fourth-generation wireless, the current 2020-era state of the art in deployed broadband mobile communications. According to the International Telecommunication Union (ITU), a 4G network requires a mobile device to be able to exchange data at 100 Mbit/sec although not all technologies branded as 4G offer this level of performance.
5G
5th generation mobile wireless broadband networks, with performance loads between 100 and 1000 times that of 4G networks. 5G communications are widely deployed in parallel with 4G systems as of 2026. 5G includes support for several different frequency bands with substantially different performance characteristics; some are extremely high speed but extremely short range (10s of gigabits/second bandwidth over ~100 meters), while others offer significant range improvements over existing 4G networks. 5G offers significantly more sophisticated management of the telecommunications network, enabling mobile network operators to more effectively allocate resources.
