4 The challenges of going mobile... Mobile phones need to move and so communication must be wireless. Mobile phones are mobile and that means we need to be able to find out where each one is currently located. Mobile phones are portable and that means they need to be battery powered. Mobile phones must not interfere with one another and that requires different frequencies. Mobile phones need to communicate with non-mobile phones and that requires them to be compatible with other services.

8 Location based services... Tracking - Emergency services - Crime detection/prevention - Parents Local information - Directions - Nearest pizza place - Cinemas Marketing - Special offers for where you are Friends - Where are they?

9 The telephone is for talking.. BUT.... On 1 st January 2007, 214 million text messages were sent by mobiles within the UK alone! That’s 9 million per hour or 3 for every person living in the UK. In 2008 we are sending 1.4 billion text messages every week – that will be almost 73 billion for the year! The mobile has changed the way we communicate – a new form of language has been created. So, how good are you at texting? How r u?How are you?

Modern electronic circuits are all designed using software and their operation is controlled by software. The design and development of the user interface – menus, graphics, keyboard functions. Making calls, sending text messages are all controlled by communication protocols. Physics Computing and ICT Mathematics Mathematics underpins all science and engineering. Mathematical models are used by all telecommunications companies to design their wireless networks. Mathematics also makes security and encryption possible.
