Traditionally, "spying" meant to record video or audio. I think voice recordings aren't the most precious thing on my laptop. It's my passwords, cookies, e-mails, and pictures.

We need to integrate fine-grained permission APIs into our Desktop OS, those we know from iOS or Android.

Hardware switches create the notion that even with malware on-board, no harm to the real-world can be done.

That's your work style then. In many cases, I got the documentation on one screen, and my IDE on the other. Other times, it's more a distraction (i.e., whenever I just have mail or WhatsApp on the other) -- I'll turn off the second monitor then.

actual development and standardization uses shorter cycles than the 5G hype cycle.

release 8 is slow. your phone would show 4G

release 14 is super fast. your phone would show 4G

release 15 will show 5G but it's just one iteration away from fast 4G.

it brings some cool techniques that boost efficiency (more people in the same cell can download things, increasing the average speed) -- and other stuff. peak download rate is one of the less interesting features, but most prominent.

> It's a bit silly to wait for a completely different radio transport before thinking of carrier and backhaul improvements, which are almost completely orthogonal.

Development on radio access and core network does indeed happen in parallel, and as far as I know, the core network overhaul was not delayed to wait for the radio-layer.

But marketing-wise, the radio-layer is what makes the phone show a 5G icon.

Much of the 5G progress happens in the core network and network interconnects.

As far as I remember, there will be some sort of "layered" encryption. The innermost layer is the user's payload, end-to-end encrypted between operators. Each service provider (responsible for transporting the data) adds patches with modifications and a signature by the service provider.

Not sure if that actually made it into the standard yet. I think the motivation is that roaming requires cost-effective routing, fraud detection,.. so there's a whole business ecosystem around that.

Long story short: I think people are working on this

Thanks!

Do those extensions require client support, and if so, is it supported by consumer devices?

[edit: re-read your post; you're well aware what handoff is, so sorry for the overly vivid explanation]

That's 'cell planning'. Roaming is different:

Let's say you're moving from your bedroom to the kitchen. The bedroom AP's signal suddenly drops. Your smartphone needs to find the kitchen AP, re-connect, and re-transmit all the packets that might have been lost.

Mobile networks assist the smartphone: it tells the smartphone that the kitchen AP will soon be in range. It already allocates and configures resources at the target AP. Then the handover is more seamless.

In theory, WiFi can do this too. But last time I checked, it seemed a vendor-specific mess.

Nice article!

However, roaming support is entirely missing. Handover between access points is really important in my experience. It would have been nice to have an overview on the current situation in WiFi.
