Why 5G in 2019 Is Like A Box of Chocolates -- You never know what you're going to get.

 In this latest blog post, I discuss what you as a consumer need to know about selecting a "5G" or "Wi-Fi 6" device. The short version is that you should get Wi-Fi 6 is you're upgrading but not upgrade just to get Wi-Fi 6. Like every other 802.11 protocol upgrade, the rest of the industry will incorporate this upgrade into their equipment on rolling basis going forward. By contrast, unless you are an early adopter who likes having an attack filled with things like HD DVDs and WiMax enabled equipment, you may want to wait a few years for things to shake out in 5G land.
