    1. 1. Wireless Networking and Bluetooth Landon Osborne and Hayden Marlowe
    2. 2. Wireless Networking• What is it? – Wireless networking is the exchange of data between devices wirelessly. This works for things like computers, laptops,
    3. 3. Wireless Networking• How does it work? – Wireless routers send out signals through microwaves, radio waves, and satellite connection. Most wireless connections work off of radio waves. The devices will receive the waves and interpret them and show that interpretation on the screen. The wireless device will then send back its own waves to the router.
    4. 4. Wireless Networking• Range of frequencies – 2.4 GHz to 5 GHz – 10 to the 8th nano meters• Area of EM spectrum being used • Wireless Networking used microwaves and radio waves
    5. 5. Wireless Networking• Timeline – In 1942 Hedy Lamarr patent a frequency hopping radio encryption technique ( Spread Spectrum technology) It was donated to the Navy and was classified to civilians. – In 1985 The us Navy declassifies Spread spectrum technology. – Federal Commission authorizes spread spectrum to be used in 3 radio bands. – Star Bucks launches wireless hot spots in
    6. 6. Bluetooth• What is it? How does it work?• Blue tooth runs on the same frequencies wireless networking, which means it also uses microwaves. It runs with 2.4 GHz. Microwaves are transferred from the master device (Cell phone) to the blue tooth device. Its has a wavelength of 10 to the 8th nano meters. The blue tooth device interprets the microwaves and creates
    7. 7. Blue tooth time Line• 1994- Blue tooth was invented by L. M. Ericsson• 2001-Ericsson merged with sony and became Sony Ericsson 7
