GiffGaff goes titsup again in 'leccy cable gaffe

Re: At least they are being very open about the issue

Emergency calls will work as the signalling sent to the network defines emergency call so connects on any of the mobile networks available, if you are on EE in the highlands outside their coverage and dialled 999 you may connect to the emergency services using Voda or O2's network but the call would be allowed as it's deemed life at risk.

Thieves jam key-fob lock signals in mystery car thefts

Lock your car before you walk away.

I once parked up in the multi storey car park in my home town, hopped out of the car as a couple were climbing intto their car next to me, walked away to do some shopping and locked my car. Upon return I saw the couple still parked up, only when I unlocked my car did the drivers door of the adjacent car open and the gentleman told me I had locked them in, deadlocked their car and activated the immobiliser so they couldn't start their car.....good job I wasn't going shopping for more than a couple of items or they could have been stuck there for who knows how long.

I have to agree with the other posters - unless I hear the clunk and see the hazard flash to acknowledge it's locked and deadlocked you don't walk away.

Why would anyone run their own base station?

Megaphone

A few truthes......

Lets dispell some myths and nip some rumours in the bud -

The femtocell connects to Vodafone using an IPSec tunnel so nobody will be able to intercept and listen in to your conversations over the femtocell. Also you configure it to accept connections from up to 32 numbers, any 4 of which can use the device at the same time. If someone isn't listed in your router they can't use it so nobody unauthorised will be chewing up any bandwidth.

You can't use it outside the UK as it registers the location, devices in the USA use GPS - quite how they are doing it in the UK I don't know but there will be some technical wizardry stopping it's use all over the world.

Lastly it's not meant to replace wi-fi, the frequency 3G runs at isn't the best at penetrating buildings......hence why it's been dreamed up. It's available as part of a contract so you don't have to shell out 160 notes for it, you can get one with your upgrade. Calls will be charged as you are still using the Vodafone core network and all the equipment like the authentication servers, SGSN's, Media Gateways, to name a few.

I guess I will come back and correct some more myths and misconceptions another time, it's too warm to do it now.

A battery back up won't be much use, if your power is out then your broadband router won't have any power either so no connection to the internet equals no femtocell.

Re: Asorted replies

Sorry Mr Weeble, when the device connects to the Virtual RNC (Radio Network Controller) it does a lookup on the source IP Address and verifies it's in the UK. If it's outside of the UK the device would be barred.

minusen - The call will still route through the Vodafone network, the only difference is that the cell information held in the HLR will send the call to the virtual RNC which routes it to the Femtocell. Call charges will be the same as ever as the routers never directly connect to each other.

Eponymous Cowherd - What makes you think you would need a fast broadband connection? a call only uses a minute amount of bandwidth, the average broadband connection is around 8mb/s - more than enough to support a good downlink speed via the femtocell.
