Help with 'Wireless Networks' in Personal use

Hey Guys -

I visit this forum frequently as I am pretty new to the whole wireless networks area.

Anyways, I am an art and art history student but I was forced to take a management information systems class and I have to give a presentation in 3 days about Wireless networks in Personal use.

The questions are


1. How are wireless networks used in the industry?
2. What improvements have occurred in the industry due to wireless networks?
3. What problems have occurred during implementation or use?
4. Have any companies lost a share of the market due to lack of wireless networks?
5. How will wireless networks continue to change the industry in the future?


All I know At this point is that WiFi and Blutooth are personal wireless networks, but ive also heard that bluetooth IS Wifi.

I am screwed either way, but if anyone here could offer any information or help, man, I cant even tell you how much I would appreciate it!

Thanks!
