The world’s first 5G networks switch on this year, promising faster data speeds and lower latency to consumers. In addition, 5G opens up avenues to new industrial applications and is a critical element to build widely connected “smart cities.” 5G is the next step to provide better networking in our increasingly technological world. Around the world, companies and governments are ironing out the finer points of how to bring 5G mobile communication to the masses. If you’ve been wondering what is 5G, this is the current state of the industry and what to expect. 5G, just like 4G technology, is an evolving standard, which is planned for and created by the 3rd Generation Partnership Project (3GPP) and International Telecommunications Union (ITU). The ITU’s IMT-2020 preparations and 3GPP Release 15 specification lay the foundations for early 5G technology and rollouts. The specification outlines 5G technology required to build these futuristic networks. High-frequency mmWave base stations, sub-6GHz WiFi-esque small and medium cells, beamforming, and massive multiple-input and multiple-output (MIMO) are just some of the more common technologies talked about. But there are also major cha...
