Given the fragility of signals at these frequencies, how useful is this? By that I mean that they're easily blocked, diffracted, whatever.

- chriscappuccio 2y ago6ghz isn't very fragile, 60ghz is
- bangaladore 2y ago60ghz is isn't very fragile, 600 ghz is
- semi-extrinsic 2y agoYou kids get off my submillimetre lawn.
- K0balt 2y ago600ghz isn’t very fragile at 50db, 6THz is! (6THz if a common wavelength for fiber)
- Filligree 2y agoFragility is a benefit; it reduces interference. This could be used for wireless VR goggles, for example.
- FollowingTheDao 2y agoHas there been any studies on the health effects that might arise from using these frequencies so close to the brain?
- Filligree 2y agoPlenty. It’s the same frequency range as cellphones, just at far lower power.
- FollowingTheDao 2y ago> It’s the same frequency range as cellphones, just at far lower power. Cite?
- ac29 2y agoIts not the same frequency range. Most cellphone networks use frequencies roughly between 500-3000MHz.
- BenjiWiebe 2y agoNot much different than 5Ghz which is heavily used currently.
- wongarsu 2y agoAs long as the signal can make it all the way from a phone in my pocket to earphones or glasses on my head it's useful.
- exabrial 2y agoThe alleged/misunderstood "fragility" can be exploited though. A lot of residential walls are gypsum board, which contains a lot of water, and attenuates microwave signals. Rather than fight this by trying to shout as loud as you can from a single AP across the house, you can put smaller, weaker APs in multiple rooms. Because of the excellent open air penetration and high frequency, you can get a multi-gig links with no interference or competition.
- dogboat 2y agoCan you get that down to low latency? Say less than 1ms for the hops?
- rnewme 2y agoNo, at least not with current stack. Each hop adds big overhead
- Filligree 2y agoWell, you can get close if you pull ethernet to the APs.
- rnewme 2y agoThen you don't have the hops, and the question was about that..
- dogboat 2y agoYes if I have an ethernet cable in each room, I just extend that to the device. Palaces may be exceptions to that.
- GreenWatermelon 2y agoBut you can't extend that cable to a mobile phone or a VR headset, in which case high-speed low-interference access points could prove useful.
