Grounding an Appliance

Whilst talking about mobile phones, I have noticed that most people's don't seem to work unless they pace back and forth...
Is there an explanation for this phenomenon?
Ah but this only really works well when the user is in an area where lots of people are walking/cycling/perambulating.

:)

Mind you, that wouldn't work inside my house. I suppose largely thanks to the thickness of my walls, and despite the nearest mast being relatively close, there are only a very small number of very specific places in the house where I get any signal at all - and I only have to move the phone a few inches from one of those places for it to 'stop working'. This does have the advantage of preventing me often getting disturbed by incoming calls :)
Mine works best when I'm sitting down.
Same here, provided I am sitting in one of those very special places in my house but, again, if I move a few inches ....!!

I can't explain the "walking back and forth" but, at least in the case of my daughters, I have an explanation for 'walking', per se. Both my daughters normally have 'better things to do with their time' than to call their parents, so it's usually only when they are walking somewhere, anyway (and hence not able to do much else!), that we often get calls from them :)

Sitting down you usually have access to a charger, but out and about lacking a charger - the pacing is reputed to help keep them charged.

And do the MI's still advise against using a phone [holding it against the ear] when on charge?

I'm not sure what 'mobile signal extenders' are available, but I'm sure there must be some around.
They do exist - I came across them a few years ago. However, they are not legal to use (by any rational reading of the rules) without the involvement of the mobile company since they involve transmitting on frequencies licensed to the networks.
Basically, outdoor antenna (or set of antennae), indoor antenna, bi-directional RF amplifier. I guess the hard part is not creating an oscillator :whistle: Where I came across them, it was one of the offices of the council's emergency planning office (my employer did IT services to them). This particular office was in the bowels of an old castle and had no mobile signal - so they'd arranged with a couple of the networks to install these devices.
Are you saying something's rubbish because it has integral ethernet ports!? I'm thinking the reverse, absence of ports makes them cheaper and not very adaptable or useful. I find WiFi access points troublesome whereas a good cable connection "ethernet cables" 100% reliable, secure and fast if the ports are gigabit ports. WiFi is great and it is but i find that it can be troublesome sometimes. I'll always plug a cable in where i can to get reliability.
Ditto. Cable for where a good connection is of any importance whatsoever, radio where cable isn't practical.
NO - do not connect the case earth to the mains earth as it will then cause the mains earth to be part of the radiating system. It needs a separate earth - including it's own earth spike, connected by a multi-stranded cable.
I was thinking that the earth screw will be to earth the case and improve the RF noise environment.

One more observation for the OP ...
Does this router also require external WiFi antennae ? It looks like it does since it has two RF connectors for them, and being in a metal case probably doesn't have internal ones.
BTW - I've dealt with Solwise in the past, always found them good people to deal with, and with good technical support.

That would be true of an RF transciever but, as for the legalities, I would have thought that the manufacturers of such things could get their products 'type-licensed' to use such frequencies- just as (I presume) the manufacturers of mobile phones do, couldn't they?

Sure, if one wanted to use it for mobile phones, it would have to be a 'wireless repeater'/transceiver such as you describe. However, for the OP's situation, I was thinking of hardwiring it to his GSM modem/whatever, which would not involve any re-transmission.

If I understand what the OP wants, I'm not seeing any difference in operation between it and MIFI - Mobile (w)ifi. A mobile sim in a gadget which provides a wifi access point, it needn't just be wifi, it could be used for a wired LAN and they are licence free. I don't think it would be possible/ legal for him to set up a mobile access point of his own, but he could use VOIP to make and receive calls, via his wifi.

I have a MIFI here, which I sometimes use to provide wifi in my caravan whilst away.

Sure - as I said, that is also my understanding, and that what Simon was talking about (in relation to licensing/legalities) would not be relevant to the OP's requirements.

I have no idea, I rarely read MI - I rely mostly upon my own common sense.
It was meant to be humerous following on from Winstons comment, I should have added a smiley face.:) But yes MI's do state [or at least did when we got instructions with the kit] they should not be used when on charge.

Likewise I agree there is no difference between a MiFi and wired LAN version, or for that matter a USB stick version. I have several of all languishing in boxes somewhere but mostly from 2G & 3G days for when working on sites with no other conectivity.

Unless the licensing rules have changed, these are not licence free devices, the licence for such a product is held by the service provider and extended to the user under the service agreement. In the same way as a taxi service [for example] hold one licence and each operator is granted use of it.

So effectively your comment is correct.

Not a problem there are many channels available and all devices hop between them all the time.

Effectively the 'repeater' acts just like a phone but instead of having a microphone and loudspeaker [and all the other bits/facilities] it has another base station attached to it which then talks to the users phone to negotiate a working frequency.

Realistically some of the mobile network works in a fairly similar way.

One of the companies I worked for owned a fully licenced portable mobile phone 'repeater' as much of our work was in basements where phone coverage was non existant. All we had to do was get a NOV for each deployment.
Our phones had to be registered to it to prevent it being used and therefore monopolised by other users, it confused the hell out of them as they saw full signal but had no service, whereas we did.
 
Unless the licensing rules have changed, these are not licence free devices, the licence for such a product is held by the service provider and extended to the user under the service agreement.
Maybe. I must say that I had assumed that the manufacturers of all the many varieties of 'devices' around (nearly all being mobile phones) acquired some sort of 'type-licence', rather than the licensing of the devices having anything to do with the service provider - but I don't know.

Seems to have been a little activity here whilst i've been away over the weekend, away, meaning away from the PC not away from home!

I have friends who have tried Satellite Broadband with two different companies and on switching the system on it's great but after a while (A few hours or Days) they were having to switch it all off and back on again. So twice a week at least they were plagued with bad connectivity until someone in the family thinks to switch it all off for 10 mins or so. With Satellite, you have to part with a lot of money every month to get a good speed and allowance.

One set of friends switched to Radio Broadband (From Satellite) and have never looked back. But you must have "Line Of Sight" for this to work.

I will have a hill top in the way of Satellite at least in part and the satellite is a very very long way away giving very poor latency.

Theoretically i'm hoping that Mobile Broadband may give me a more reliable service given that the masts i have to choose from are very close (compared to a Satellite) and they are in full line of sight without obstructions at all whatsoever. Given a perfect setup, compatibility of equipment and service i should, i hope get somewhere near 300Mbps with 4G and close to 876Mbps on 5G when available. However, i accept that in reality anything similar to Fast Fibre say 80Mbps+ will be fine.

The two families that i know who tried satellite couldn't watch a film on Netflix or the BBC iPlayer without buffering and often had to reboot the system to finish a film.

My experience of Mobile connectivity is that whilst speed may vary for all sorts of reasons i never have to switch my phone off and back on again to regain a connection. It will reconnect, switch masts adjust the speed etc all on its own and fairly quickly too.

I have now had a reply from the manufacturer about the Ground Screw.... It needs wiring up to a ground spike to protect the equipment and me from a lightning strike.
 
Re Licencing...

My understanding is that all such devices require a licence to use, however i believe that the end user, me, you and everybody else are automatically licenced when agreeing to T&C'c with a product service provider.

A, A lifetime licence is granted on the purchase of the hardware perhaps? Home WiFi, Drones, GPS Devices, Freesat for example, i'm sure there are others, CB Radio..... does it still exist?
B, A licence is granted when signing up for a service with a service provider? Mobile Phones, Radio & Satellite Broadband, i'm sure there are others.

So the user doesn't need to purchase a licence, it's granted to them on the purchase of hardware and or by a service provider. The end user doesn't need to apply for a licence.

There are situations where an end user does need to register to be licenced..... Ham Radio!? I think this is now free if you register online, but you must still be registered even though it's now free.

The only exception in my opinion that affects the majority of us is the TV Licence!!!!!! We have to buy an annual licence to receive BBC content in it's various ways but i don't think of this as a licence to receive a broadcast any more but rather a stealth tax or as bill to pay for the creation of BBC programs for us to watch. The licence fee pays for what we watch rather than the licence to receive a signal via an aerial. Splitting hairs perhaps!!

There is quite a bit more involved than just that :)
