NHS Contact Tracing App

And of course some people may give their phone to the wife to carry, and then make the wife walk six feet behind them.

Sometimes you're just weird

Im not bothering to read the whole thread.
Simply put, the UK government couldn't organise a shower in a rainstorm, they have no hopes of managing an app across millions of users and keeping the data private.

Not coming to a phone near me any time sooner or later.

Exactly - it's not coming to a phone near you because it'll never happen.. The virus will be over by the time our Gov sort anything worth while out!

You started it.

Still won't be able to tell if a phone is near by in a pocket or far away in someones hand

But Dom Cummings family and friends will be rich off the back of it. If only we knew their names.

If only we had the ability not to cut our noses off in spite of our faces and had a look for ourselves!!

Surely you mean 'cut off our Notchs to spite our face', it's a price worth paying.

Come on, tell me the names.

 

[sodthisforfun]

Nah, this is much more fun

I see, you don't understand.

Bluetooth signal strength is reduced by any obstruction. If you've got your phone in a case or a pocket then the signal will be much weaker than if you're a bit further away but have it out. It's a common downside to using Bluetooth as a proxy for proximity.

Long arms could be a problem

Let's face it this world beating app was trialed on the Isle of Wight

Yep. The Isle of Wight

Yes exactly the gene pool there must be getting a bit thin

If u get my drift

Bit like Iceland

I hear the new government approved app doesn't need any fancy gadgets.
We all carry a ball of string around with us so that the government knows where we've been.
I understand the PM is calling it the 'unravel cottonwool' policy.

They include the phone make and model which allows you to calibrate their signal strength more readily. Still won't be able to tell if a phone is near by in a pocket or far away in someones hand.

Estimating distance between two mobile phones by received signal strength is never going to work.

A common sensitivity parameter for the sensitivity of a radio paging receiver is the 8 Position Average. The person carrying the receiver stands facing the transmitter for the first position, then turns 45 degrees to the second position, and so on for the other 6 positions.

Typical results for a receiver in a shirt pocket and on a UHF channel are :- Best position: 5μV/m, 8 Position average: 9μV/m

If the two persons have their mobile phones in shirt pockets and are facing each other then the measured ""distance"" ( based on field strength measured by the mobile phone ) will be far less than the measured ""distance"" if they are at the same real distance apart but facing away from each other.

I see no reason why this variation does not apply to mobile phones being carried on a person.

by claiming ignorance Fillyboy is somehow also claiming it isnt true.

he thought it would be easy to disprove your tongue in cheek dialogue as he assumed it wasnt based on fact.


Its a grim fact that many of the Covid decisions by this government are driven by giving contracts to their mates.

Interesting, if you have an android phone, go into settings, then into Google setting and see what you have there.

There was a brief TV news item showing the German army looking at that sort of aspect. One in the middle and a number pacing around him in a circle - all in drill timing of course. I'd assume that is the sort of thing they were testing.

Looking around at info on mobile phone radiation patterns they appear to have managed to make them omnidirectional just like the old types were that had an aerial sticking out of them.
