Yep, just set your Wi-Fi routers to use 6GHD and trample all over the other people in the band until they figure out that they can't control it.

Next they are gonna take away amateur radio frequencies so it would be illegal to communicate outside of the internet.

Then its very easy to do censorship, just turn off power to ISPs and its information blackout.

[–] MangoCats@feddit.it 2 points 13 minutes ago

For what it's worth, I think Cruz's proposal (all of it) was defeated 99-1.

This would need like a Canadian or Mexican to help provide the internet from across the border, because if they pull the Iran style blackout there will be zero internet for the entire country.

Meshenger app and mesh networks would still work, back to the BBS times we go

Well whoever ends up buying that band is in for a load of shit because I and a lot of other people are NOT going to stop using 6GHz WiFi

Same thing with Meshtastic. Go ahead and see just how much you'll waste your money.

[–] deranger@sh.itjust.works 2 points 3 hours ago (1 children)

What do you mean by same thing with Meshtastic, are they trying to sell spectrum around 900mHz too?

[–] LodeMike@lemmy.today 1 points 3 hours ago

IDK I heard something about it. I think it may have been the 866 MHz one?

[–] cogman@lemmy.world 56 points 1 day ago

Yup, the band is already littered with 6g devices. It'd be a stupid purchase.

But also, 6GHz is somewhat of a useless band for carriers. It's high enough frequency that it'll get absorbed by most things yet low enough frequency that it'll struggle to really carry a whole lot of data.

[–] cmnybo@discuss.tchncs.de 28 points 1 day ago (2 children)

The cell carriers don't need more bandwith. 5G is already quite fast with the existing allocations. The only times I've used 5G and thought it's too slow has been in rural areas where the issue is a lack of nearby cell towers, not a lack of bandwidth. The cell carriers already have loads of millimeter wave bandwidth available for use in densely packed, urban areas where the lower frequency bands are insufficient.

It's WiFi that should be getting more bandwidth. Home internet connections keep getting faster. Multi gigabit speeds are now common in areas with fiber.

[–] pupbiru@aussie.zone 1 points 18 minutes ago

and on top of that, 5G afaik is specifically made so that if you need more density, you can turn down the cell power and install more cell sites rather than take more spectrum

it was designed for venues like sports stadiums so you could keep installing more and more cell towers inside stadiums etc to accommodate huge crowds

[–] JasonDJ@lemmy.zip 11 points 1 day ago* (last edited 1 day ago)

This exactly. Wifi is damn near unusable in dense residential settings. It'll cut it for streaming and web browsing, but much more than that and you'll feel the pain of interference from all the other wifi APs in the area.

Especially with most of them defaulting to 80MHz on 5GHz and many of those defaulting away from UNII-2. which leaves 4 non-overlapping channels (with one of them giving trouble with a lot of devices). We're right back to where we were in 2.4. Even worse, I think, since wifi is more ubiquitous.

[–] chiliedogg@lemmy.world 46 points 1 day ago (2 children)

It's a bad band for cellular. It's short-range and shit at penetration.

It's really not even that good for wifi unless you're close or have a mesh network with APs all over the building.

Because of its shortcomings as a communication bandwidth, it's really, really good at cell-based positioning.

[–] undefined@lemmy.hogru.ch 11 points 1 day ago (2 children)

mesh network

Or traditional network with Ethernet backhaul and lots of access points. I really wish mesh networks would die off honestly.

[–] curbstickle@lemmy.dbzer0.com 11 points 1 day ago

Like anything else, they have their place. But they've been shoved into use cases they dont fit as well.

[–] chiliedogg@lemmy.world 6 points 1 day ago (1 children)

Sometimes re-wiring a house or building isn't as practical as setting up a mesh network that's good-enough.

[–] cmnybo@discuss.tchncs.de 3 points 1 day ago

Mesh should be an option of last resort. It reduces the speed and increases the latency quite a bit. The only thing worse is power line networking, which has the side effect of turning your whole house into an RF jammer.

[–] MeekerThanBeaker@lemmy.world 14 points 1 day ago (1 children)

So if I'm reading this right... wired Internet providers are against this due to home Wi-Fi Internet speeds and phone providers are for this for mobile speeds/bandwidth?

I don't know how I feel about this as I currently have T-Mobile home Internet and it's not the best experience... but it mostly works and it's cheaper than my previous cable provider. However, home Wi-Fi really needs 6 GHz for future IoT devices.

But I am definitely against it because Ted Cruz is for it. He obviously is getting paid/bribed by the telecoms... and he sucks.

[–] HiTekRedNek@lemmy.world 17 points 1 day ago (2 children)

Eh, IoT devices typically use 2.4ghz, or even 933mhz...

[–] fuckwit_mcbumcrumble@lemmy.dbzer0.com 19 points 1 day ago (1 children)

Yeah IoT devices don't need bandwith, they need range (at low powers) and those lower frequencies get them that. 6ghz wifi has pretty small range and is awful for IoT stuff.

[–] Septimaeus@infosec.pub 1 points 6 hours ago

Right, I figured they meant in order to make room. There’s too much cluttering 2.4 — zigbee, zwave, bluetooth, IO peripherals, microwave ovens, cordless handsets, walkies, and more. WRT general WiFi traffic, in dense residential settings 2.4 is often only used for initial client device handshake.

I thought wifi was on 2.4ghz, and the new ones were on 5ghz?

[–] AlternateRoute@lemmy.ca 34 points 1 day ago (1 children)

Current generation wifi 6E and 7 add 6Ghz which offers substantially more bandwidth / speed.

Wifi 7 also allows devices to use 2.4/5/6Ghz at the same time instead of just hard switching between them.

Would be a major setback since 6Ghz allows devices to easily hit Gigabit speeds wirelessly.

[–] xthexder@l.sw0.com 1 points 7 hours ago* (last edited 7 hours ago)

Yeah, I've got Wifi 7 set up and it's awesome. I've got a single access point, and I get full gigabit in my office with line of sight, and it auto switches to 5GHz or 2.4GHz when I move too far away. It's also great for apartments since it's more easily blocked by walls, there's way less interference from neighbors.

[–] JasonDJ@lemmy.zip 1 points 14 hours ago

Nah wifi was actually originally on 5GHz spectrum, with 802.11a. It came out shortly before 802.11b, which used 2.4GHz, and was objectively better...but component shortages for 802.11a devices made the inferior 802.11b more successful on the market.

Then in 2009, after 802.11b and 802.11g came 802.11n, which used the 5GHz spectrum, and introduced dual-band routers to consumers.

Most recently, 6GHz got allocated with the advent of Wifi 6E and Wifi 7.

[–] TheFogan@programming.dev 11 points 1 day ago* (last edited 1 day ago) (2 children)

802.11a is over 20 years old, fortunately this law isn't talking about shutting down existing routers. the 6 GHZ is the next frontier to expand to, the military already owns the 7 GHZ spectrum... So the 6 GHZ is the one that can be expanded into. Of which origionally was planned to be made for the next generation of wifi... but now is going to be sold off to phone providers to use in the next generation of mobile networks.

So in short, our existing routers will continue to work as designed, but future routers will not be making any leaps forward.

Basically the choice between better faster wireless LANs, is getting killed in favor of better networks for cellphone services... of which the carriers will set the price on.

802.11a was 5ghz, 802.11b was 2.4ghz. Both developed at the same time.

802.11g was 2.4ghz and extended b since 2.4 took off faster than 5ghz in the market.

Since g, n onwards has been used across both bands.

Since 802.11ax we now have 6ghz.
