"Super fast 5G cellular networks are hot as major wireless carriers from Verizon to AT&T deploy the service, but it’s unclear if the infrastructure is in place for in-home 5G to replace current cable-based broadband.
The 5G-enabled future seems kind of distant. Real estate developers would need to put fiber-optic cables in homes and office buildings, since 5G doesn’t pass through walls, windows, or people. And most developers are not constructing projects or retrofitting existing properties that would allow 5G to be delivered to homes because it’s simply too expensive to implement.
Fiber-optic cables, which run through the walls and the floors of buildings, are required to receive 5G signals indoors, according to Dan Littman, principal of technology, media and telecommunications at Deloitte Consulting LLP. And only some developers like The Related Companies are willing to pay for the infrastructure. Related’s massive Hudson Yards 28-acre mixed-use development in New York City is wired for 5G."
