Wi-Fi Functions

Slide 1:

1. Wi-Fi just like radio wave, blue tooth, or the signal for walkie talkie  

2. It transmit data through one terminal to another, i.e. internet.

3. It is a replacement of Cable internet, free the people and the electronic devices.

4. Easier to hack through since you can stand anyway within the signal range, can ask how in question time.

Slide2:

1. Wi-Fi name of a trademark, owned by a non-profit organisation.     Wi-Fi Alliance

2. All Wi-Fi product communicate under 802.11 standard protocol.

3. Vic Hayes key figure, from IEEE, Father of Wi-Fi.

4.  John O'Sullivan, an Australian, CSIRO researcher, under project

“A failed experiment to detect exploding mini black holes the size of an atomic particle” and led to his invention which function in faster and stable Wi-Fi data transmission.  Later won CSIRO 250 million dollars from 14 Technology Company, for infringement.

Slide 3:

1. Currently we use Wi-Fi mainly as a tool to surf the internet through our electronic devices.

2. That leads to a very practical use，of work place communications. Example: instead of logging on to a desktop and check your work emails, you can use a tablet that connect to a Wi-Fi and going through them and reply them, mobilised work communications, thus it alters work efficiency.

3. Not just that, many printers have Wi-Fi application as in user can printer from any electronic devices which transmit data through Wi-Fi and print. Similarly, many digital camera can upload picture it took instantly, to PC, again through Wi-Fi.
