    I believe @skillissuer is pointing out that in order to broadcast the 1500km that Dick Tracy’s watch was said to have would require a ton of power. That power would make it dangerous to have on your wrist. That’s just what I pieced together through context though.

        yeah sorry if it was unclear. this problem is avoided by talking to some other station, usually GSM tower or satellite. when you don’t have this luxury, you need high power, large antenna array or you get lower range
