… been doing some thinking regarding Bluetooth’s capabilities on mobile phones. Well, by now, some of us would’ve heard about Bluejacking (the act of sending a message as a namecard entry on the mobile phone to another phone using Bluetooth technology).

The idea I’ve come up is a further extension of what Bluetooth can be beneficial in the mobile phone. I’m not sure if anyone came up with something similar, but for sure, it’s not in our mobile phones yet. So here goes…

The ability for the mobile phone to use Bluetooth signalling to call other Bluetooth-capable mobile phones within the range (normally 10 metres without obstruction). The system would be like a call made over the cellular network - phone will ring, will show (this time, the Bluetooth mobile phone’s device name instead of the phone number) and allows the receiver to accept or reject the call. How the caller can identify who s/he can call on the Bluetooth phone would be to Discover for nearby Bluetooth-capable phones and then choosing which one s/he wants to talk to… and that my friend, is what I would call BlueTalk. smiley

Of course, some of you would be concerned with privacy and also the idea of strangers calling you up within 10 metres radius of you, no problem, just turn off the Discoverable mode and no other Bluetooth phone can discover you. Alternatively, for a select group of people, you can have the pairing made between the 2 phones, and even without being in Discoverable mode, both can talk as long as within range (and a call being initiated first of course).

As for talking while there’s an incoming cellular call - simple, just use the same feature of Call Hold/Waiting or even multi-party conferencing since the phone can process both Bluetooth and cellular network’s signalling simultaneously. Isn’t it cool? smiley

Imagine the marketing possibilties and hype that come with this idea. It’ll definitely attract the attention of teenagers and young adults. It’ll definitely attract the attention of typical Nokia users (yeah, those who fancy a FM radio feature more than a Bluetooth capability, those who wants more interchangable covers available for them, and those who were willing to try out cameraphone even though it’s a bricksize smiley )…

I think I’ll go pitch my idea to the Sony Ericsson peeps smiley

I’ll be damned if Nokia does this first…!
