India has 15% fixed broadband penetration. So let's say you've got a town of 100K households. You can;

A) give the richest 15K of them absolutely no faster WiFi whatsoever because 5GHZ will not be congested at all for them (so there is no problem to solve really)

OR

B) you can have the mobile carrier install a 6Ghz base station on every other telecoms/power pole in town and offer up terabits of mobile data capacity available to everyone throughout the town.

What's the most efficient use?

The most efficient way to extract money from people is to sell off the spectrum to the highest bidding rent seeker, I agree.

As for most efficient use of the resource, well, consulting my spectrum analyzer, ISM bands are winning by a mile and we should want more of them.

[matt-p]

Sure obviously giving it to WiFi and then installing town wide free WiFi would be the absolute most efficient option but I'm trying to stay realistic.

[lxgr]

Wi-Fi is not a very efficient way to cover a whole town, due to its inherently low range (at least when involving consumer devices on one end). You'd be spending a lot of resources on base stations that never see any usage.

[ajross]

WiFi literally covers basically all of the urban US already, I'm not understanding this point.

It's true that there's no single service one can sign up for and you have to bounce around cafe and Xfinity and whatever "Free WiFi!" networks are being offered. Which is definitely annoying and it's nice to have a single company sell you service in a neatly packaged "phone" product.

But again, trying to phrase that as a technical point is ridiculous. Free bands are just plain better, technically. You get more data to more people for less money using open spread spectrum protocols than you do with dedicated bands. Period.

[jdewerd]

I never said anything about free or government-run WiFi, just about auctioning off the spectrum. Companies that build out the infrastructure should be able to charge for access, but they shouldn't be able to prevent others from competing by paying the government for exclusivity. That's a scam.

[matt-p]

It's a technical/commercial necessity to have exclusive use over the spectrum in a given area. If you don't believe me why doesn't every city in the world have a paid wifi network? With 5Ghz it should be faster than typical 4G/5G speeds, and it only needs lampost level APs, pretty similar to the microcells that carriers deploy but an order of magnitude cheaper. Instead mobile carriers would rather buy 3 or 6ghz spectrum that only ever gets used in cities anyway, why not wifi in the cities?

ISM is tragedy of the commons; make it free, let anyone do anything and it becomes junk. Carriers need something they have exclusive use of.

[jdewerd]

ISM is thriving, the only tragedy is that carriers haven't figured out how to charge rents on it and that's a tragedy for them, it's a spectacular success for everyone using it for free.

Carriers don't need 6GHz for backhaul. They have fiber and cable and (other) microwave. Not to mention the ability to shape their own links with antennas and beam forming and do a good job of it rather than a "default job." What they don't have -- and shouldn't be given under any circumstances -- is the excuse to build a moat in the bustling public park.

[ndriscoll]

At the very least, I don't see a need to grant exclusivity across an entire country. e.g. from my home, I can see 5 wifi networks including mine. Of those, only 1 other than mine has a 5GHz signal that reaches me, and everything other than mine is in the -80 to -95 dBm range. There's simply no need to reserve short-range signals in the suburbs in the way that there is for block of giant apartment buildings each with 100s of networks on top of each other.

On top of that, mobile data is quite expensive in the US, so the only time I have data when out and about is... when I'm on free public wifi networks (which is most of the time). So I don't see much reason to give more of a monopoly to mobile providers. I honestly don't even see a use-case for cell service outside of super rural areas; the only reason I even have it is because it's necessary for MFA. Cell providers are legacy tech as far as cities are concerned IMO.

To me it'd make way more sense to me to let wifi have more bands with stricter limits on power levels, and any exclusivity should be to municipalities who can contract with companies to build and manage their infrastructure.

> On top of that, mobile data is quite expensive in the US

It's not 2015 - that narrative is long dead. There are countless options for unlimited mobile data (5G, with hotspot) for $15-$20/mo.

[matt-p]

I certainly agree about regional licensing. I think the best scenario would actually be to allow some for WiFi and some for carriers, especially since selling licenses is a two way door in a way that ISM isn't.

[esseph]

The best plan would be fiber + fixed wireless + satellite. This is considering cost to deploy, end subscriber cost, and overall performance.

Fiber won't go everywhere, fixed wireless extends the reach much, much cheaper than LTE, satellite fills in the gaps.
