Cisco CEO Robbins: "There's no hype about 5G, it's an incredible leap."

https://www.expansion.com/economia-digital/protagonistas/2019/03/05/5c7eaf9de5fdeaed308b4574.html It promises dramatically improved performance for mobile workers and businesses. Improved speed, latency and power consumption.

What is 5G

The term 5G refers to the fifth generation mobile network. It features a new technology improved from the current 4G/LTE, mainly in terms of speed, latency and power consumption. It is a new way of using mobile devices. It offers advantages such as faster connection speed and greater autonomy in the device, despite causing a higher performance. While the maximum speed of 4G technology is only 1 Gbps, the International Telecommunications Union has set the speed of 5G at a standard of up to 10Gbps, which is faster than fiber optics. In short, 5G is the next generation of mobile data. As we have already mentioned, the 5G speed promises to be far superior to the 4G mobile network and 100 times faster than current wireless systems, this means a total revolution in the IoT. Internet of Things: keeping everything connected to your phone (home, health services, automobiles, machines, appliances...) Another of the many advantages of 5G is the reduction of latency. The time for the transfer of a data packet will be reduced, being this latency between 1 and 4 milliseconds. Communication will be immediate, as will the downloading of files. 5G technology will be fast, mobile and secure.

Feature	4G	4G+	5G
Speed (Mbps)	200	1200	10000
Latency (milliseconds)	100	20	1-4

Speed and latency also support better connectivity from more locations, as well as connecting multiple devices simultaneously. Multiple-Input Multiple-Output ( MIMO) technology allows us to transfer more data between devices in the same space. This means that if we add more antennas, we can carry more data packets in the same time. That is, a higher transfer speed in the same time. This is what 5G proposes; up to 100 more connected devices per unit area compared to 4G and LTE networks. Lower latency improves the performance of business applications and other digital experiences such as online gaming, video conferencing and autopilot cars... While previous generations such as 4G LTE aimed at ensuring connectivity, 5G technology takes connectivity to the next level by offering connected cloud experiences to customers. 5G networks are virtualized and run through software, and leverage cloud technologies. 5G architectures will be software-defined platforms, where network functionality is managed through software rather than hardware. Advances in virtualization, cloud-based technologies, and IT and business process automation enable the 5G architecture to be agile and flexible and provide anytime, anywhere user access.

5G and Wifi6 to be deployed together in the enterprise

For enterprise IT departments, it will be a challenge to manage these access technologies separately, and it will be a priority to have them as integrated systems, with unified policies, security and analysis. Users and devices will need to move between 5G and Wi-Fi 6 systems, and the IT manager will want the experience to be seamless and easy to manage at scale. The 5G network will also simplify mobility, with seamless open roaming capabilities between cellular and Wi-Fi access. Mobile users can stay connected while roaming on outdoor wireless connections and indoor wireless networks without user intervention or the need to re-authenticate.
