    Is it possible to have a two way voice conversation over bluetooth
    featured mobile phones without the use of gsm network? What is a
    typical mobile phone bluetooth range and can it be easily extended
    with insertion of an amplifier IC?
    thanks

    Bluetooth is usually advertised as having a 10 meter range but to be honest
    I've never got it to work *reliably* over about 5 meters. I dont see much of
    a market for walkie-talkies with a 15 foot range :-)

    i guess class 2 (100m) devices would change that. although my t610 can reach
    a BT signal from a floor above so even a 15ft range walkie talkie would work
    well as an internal intercom thing...

    i just dont think the mobile operators would allow the feature to be
    included in a phone. i can imagine it taking a chunk of their revenue.

    Motorola make a cellular phone which can also be used as a "walkie
    talkie" to a same-brand phone, i.e. back-to-back operation without
    involving the network. It doesn't use bluetooth for this though.

    You can get PMR radios for next to nothing, you would really be better with
    on of them!.

    I don't see the point when 446MHz licence-free walkie talkies can be had
    for 30 quid or so now.

    The SE Z1010 is supposed to have a range of 100m for bluetooth, that
    said my SE P800 is right next to my laptop and the laptop never seems
    to pick it up!!

    Good concept, as with most things though seriously unreliable, even
    when paired with another device!

    Typically, no. 2-way audio over bluetooth is perfectly possible
    (that's how bluetooth headsets work), but it's generally not supported
    by phone handsets. I don't know if that's a limitation of their
    bluetooth chipsets, but it may just be a question of firmware.

    Most bluetooth phones have a range of ~10m (class 2). You might get
    some class 1 phones with a range of ~100m, but I doubt they are very
    common. As ever with quoted ranges for rf kit that's best-case with
    nothing between you and the receiver, real world range is usually
    worse.

    I think it's more likely that phone manufacturers don't think people
    want that capability (and with a ~10m range I can see why - you could
    just shout!), rather than it being technically very difficult to do.

    Bluetooth is a non-starter for this application, but what about PTT (push to
    talk) over GPRS?

    i have tried "Visual communicator" for symbian OS mobiles. it doesnt work in duplex mode, as it
    sends audio files with max. 10sec length, there is also a chat function. In order to establish the
    conversation both phones need to have the software running.
    At the moment its doesnt make sense to use it, unless you are in a foreign country which charges
    heavily for roaming. Hopefully costs for data will be cut by providers in the near future!

    Martin
