Making connections

Smile Taking a picture of the class and transferring it… What methods could I use?

In this lesson students are learning about: methods of connecting a mobile phone to another device transferring data between mobile phones factors affecting speed and volume of data transfer mobile phone peripherals

At the end of this lesson students will be able to: explain methods of transferring data between mobile phones select and use an appropriate method of data transfer explain the principles of Bluetooth technology and security/privacy issues associated with its use

Transferring data between phones In groups (each group needs two mobile phones) you are to take a picture with one phone and experiment with different ways of transferring the picture to the other phone, including swapping memory cards, Bluetooth, MMS, and the Web. Each group is to capture their experience with each transfer method by filling in Data Transfer Table.doc and to rank each method according to (1) ease of use, (2) range, (3) speed and (4) 1-to-1 or 1-to-many.

Present your findings Present your rankings in a class feedback session. Are they the same? If not, why not?

What is Bluetooth? Bluetooth is a wireless technology standard for exchanging data over short distances from fixed and mobile devices, creating personal area networks (PANs) with high levels of security.

How it works “Packets” of data can be transferred very quickly over a short distance. Bluetooth uses a tiny amount of radio power (1 thousandth of a watt) to transmit the packets, so it is ideal for battery operated devices. It can transmit to up to 7 devices simultaneously.

What is it used for? Hands-free operation of mobile devices in cars Sending messages (sometimes negative see “Bluejacking”) Sending images and files between devices Bluetooth enabled printers, mice, keyboards, other “peripherals”

What security/privacy issues might be associated with its use?

And finally Investigate other applications of Bluetooth technology. Pick the most interesting/wacky application and prepare a brief summary of it.
