WiMax
 WiMax Video



 Basically wi-fi on a larger scale (metrpolitan area) and much much faster
  speeds than 3G or HSDPA. Not limited to wi-fi hot-spots



 WiFi is only limited to around 10-300 feet.



 WiMax is limited to between 3-10 miles!



 More efficient than Wi-Fi.
Where for art thou WiMax
 Wider use of Wireless equipment (such as Apple iPod Touch, Smart Phones
  etc).

 Faster internet use on the move, anywhere.

 Able to transfer files, emails etc (via the internet) significantly faster than
  Bluetooth etc.

 FULL internet access on the move (streaming etc).

 Free or subscription based service.

 Can reach out to rural places.

 Security issues (a public network – your information is public).

 Expensive to setup. VERY new technology so not wide-spread yet.

 Few technologies (phones etc) support it yet.
GPRS
 Global Packet Radio Service


 ‘Always On’ mobile internet (pre-dates 3G and HSDPA)


 Common in all mobile phones today in the UK.


 Without it, today you would not be able to:
    Send and Receive MMS (Multimedia messaging service)
    Instant Messaging on your mobile
    Access the internet on the go via WAP (Wireless Application Protocol)


 Now overtaken by 3G, HSDPA and EDGE.
Today’s Task
 Imagine WiMax has been launched in Yarm. Everyone can now access
  free WiMax wherever they are.

 As a technology specialist you need to create an advertisement.


 The advert must promote WiMax clearly and simply. Explain what
  WiMax is and the benefits to them.


                          KISS
                 Keep It Short & Simple
