  • phone antennas

    Do cell phones contain a separate antenna each for
    phone network, Wi-fi and Bluetooth?

    Also, does Bluetooth include any security? Like,
    if a user is listening to his music through a Bluetooth link,
    can I pick it up, with my earphones? Or, more
    problematically, when he makes a purchase with Apple Pay?

    Each transceiver has its own separate antenna.
    Bluetooth5 allows for multiple connections from a single master. You can't eavesdrop -- the Bluetooth5 equipped smart phone must make the Bluetooth connection to both devices.
