    They thought bluetooth is only for cellphone.
    This misconception because they don’t understand the classification of wireless network.

    There’s at least two popular wireless network nowadays:
    WPAN (Wireless Personal Area Network) & WLAN (Wireless LAN). Bluetooth is considered WPAN because of it’s limitation on range (10-100 meter max). Although they use the same frequency (2.4 Ghz), they are using completely different technology. Bluetooth using FHSS (Frequency Hopping Spread Spectrum) and recent WLAN using DSSS (Direct Sequence Spread Spectrum) & OFDM (Orthogonal Frequency Division Multiplexing).

    There’s a good things in FHSS used by bluetooth. It’s more interference resistant than DSSS/OFDM. You can use bluetooth BEST for custom application like: In store new promotion, finding the car parking free space, In mall new events, Personal Webserver -> when someone approaching you, your PDA/smartphone broadcasting about you and who you are looking for or what’s your offer to people close to you.

    But you can’t depend bluetooth for long-range and high speed/high bandwidth application like internet links or inter-building wireless links for example.

    So, after they know the “know-how” and what is the purpose of the technology was first to be designed. They can decided which technology is best for which purpose. Hope this little info help you if you are on developing bluetooth applications. And if the application already finish, spread it to the world via many webhost who host freeware/shareware software, okay?
