Will 5G replace WIFI?

[DelJo63]

Short answer is: NO

sdxcentral.com has some 5G Q&A resources that are instructive that you really ought to read:

• how vRAN Changes the 5G Game
• What Is the Radio Access Network?
• How Is the RAN Network Evolving?
• The Role of C-RAN in 5G Networks
• What Is 5G Network Slicing?
• What is Dynamic Network Slicing?
• What Is 5G NR?
• How Is 5G Different From 4G LTE?
• The Top 5G Use Cases
• What Are the Top 5G Security Challenges?
• Key Elements for 5G Networks
• How Do We Transition From LTE to 5G?
• What Are the Top 5G Business Cases?
• What Are the Essential 5G Products?
• How 5G NFV Will Enable the 5G Future
• Defining 5G Architecture

Even though 5G use cases aim at iOT devices, no one is going to rush out and replace ALL their networked devices eg: video doorbell, remote controlled household appliances (thermostats, AC, refrigerators, smart TVs, surveillance, cameras, etc...). Due to such high frequencies (24ghz and above), 5G will not only have a shorter range, but the walls in the building will greatly impede access from room to room.

Summary: 5G devices will (or have) appear for our smartphones long before other devices for which the technology is intended.

One other thing that is never mentioned in millimeter wave is rain fade. I have been using 24 and 60 GHz PTP and PTMP radios for quite awhile and every time it rains they modulate down to nothing and performance falls flat. obviously they will still have 4G backup but I am willing to bet that the links will not hold up in rain.

· The 5G operates through a particular operator licensed by the government. The other difference is regarding payment.

... you need a subscription to access service and you have to pay for that.

Just like all other Cellular systems, you pay for service

Also, you cannot network computers with 5G in a soho environment like you can a broadband router to share files, printers etc. The typical router can network up to 24 clients. A big advantage of 5G, however is the ability to go anywhere.

As far as I know, you could never use any cellular connections as "LAN".

You could however, simply use any cheap firewall in NAT mode, with a 5G device as "WAN" and other stuff on the "LAN" side.

That theory is sound, but the connectivity is a big hurdle. How does one connect the 5G device to the firewall -- usually the input is cat5/6 ethernet cable.
