As someone who has a regular 3 hour train ride with work, 3G isn't good enough through a lot of the country. You will be hit by many comms black spots


But if you have to use 3G, rather than fork out for a new contract can you use your phone (Android, iphone 4) as a wifi hotspot (ie it pretends to be a wifi hotspot, allowing your wifi ipad to use it's 3g connection)

Hmmmm.....


This is getting bonkers, through a lack of common terms ;-)


3 is a telecoms provider - like Orange or O2.


3G is a telecoms standard that allows data transfer - if you already have a 3G data service from a telecoms provider then you can download data (like the internet) to your compatible device.


iPad 3G is an iPad that has 3G standards compatibility, but doesn't come with connectivity unless you buy a data package from a telecoms provider.


wifi is a connectivity that comes from a local router (small box with an ariel). To access this you'll need a password. It's possible that some train services have these small boxes on their trains and will charge you a price for the password.


bluetooth is a way for your laptop to connect to your mobile telephone. If your telephone already has a data service (can you look at the internet on your mobile phone?) then you can use bluetooth to connect your laptop to your phone and then use your phone to access the internet.


It sounds complicated, but it's not. It's just a question of getting used to it - you wouldn't confuse a bicycle with a car would you?

    • If you like very good quality South Asian food then Babur in Brockley is offering a well priced, for what it is, Christmas day menu with sensitively priced reductions for a more limited children's menu. They also have a compelling wine list and their specialist cocktails are phenomenal. Not traditional Christmas fare, but then that might be an additional recommendation.

    • Dear families,   My name is Eleanor. I’ve worked in NHS Child and Adolescent Mental Health Services for the past eight years, and I’m about to begin an Infant Observation course in preparation for psychotherapy training. I’m looking for a baby to observe as part of this training.   The observation involves me visiting a baby and their parent for one hour a week over two years, with the aim of deepening my understanding of early emotional and developmental processes. Taking part is a generous contribution to the training of future child psychotherapists — ultimately supporting the mental health of children and families.   Both of my own children were observed as babies, which I found to be a really positive experience. Having an observer gently witness my babies’ development helped me notice their weekly changes in a new way, and I came to appreciate the calm, consistent presence of a trained observer. I was sad when the observations ended!   If you — or someone you know — is expecting a baby due before the end of February*, I would love to hear from you. You can contact me at +44 7977 910018 or [email protected].   Best wishes, Eleanor
    • I rarely iron, so my massive ironing board is just taking up unnecessary space. Does anyone have one of those little ones that you can use on an ordinary table?
