There’s been a lot, A LOT of talk lately about the future of wireless technologies and whether or not Wi-Fi will be replaced. Some of it is true, while some is not. With that said, I wanted to dig deeper into 5G and Wi-Fi as a follow-up to my blog post, Is Wi-Fi 6 the Dominant Choice for the Future of Wireless Technology? and prior to my upcoming webinar Wi-Fi 6, 5th Gen, CBRS Wireless Technologies Competitors, Collaboration, or Just Coexistence.
So, What is 5G?
5G stands for 5th Generation, the fifth generation of cellular mobile communications. From an evolutionary standpoint
Now begins the 5G era.
5G is based on the International Telecommunications Union (ITU) IMT-2020 proposal (2012), ITU’s vision of what global telecommunications should look like by 2020. At a technical level, it was designed to
However, the key business value was to deliver highly reliable communications to support multiple, simultaneous mission-critical applications. I recommend the IEEE’s website to learn more information about 5G.
What’s So Special About 5G?
The goal for 5G was to provide wireless communication services that could support any type of device or application, with each getting the level of service required. It also would not be limited to a single radio technology.
Although it did incorporate advancements in wireless access technology, most of the real benefits will reside in the core network. Terms thrown about are network virtualization and network slicing, with the concept that carriers can define virtual networks that would reside above the physical layer infrastructure. These virtual networks can then be used to segment the network for specific use cases or market requirements. In this way, the network can quickly be reconfigured and scaled for new levels of services are needed.
Ok, 5G is Interesting, But Will It Replace Wi-Fi?
Easy answer, No!
