Encoded voice may be transmitted in the ISM bands, e.g.
915, 2450, 5800 MHz. WCS bands may be used depending upon the
aplication.


** Like "spread spectrum" or "DECT " cordless phones do.


Aside from that, to achieve several hundred feet (or more) range in a
shopping mall using a low-power (<1mW) transmitter and a small or
built-in antenna is feasible,


** Huh ??

A cordless phone could not reliably do that and they use much more than 1
mW.


but you will need a better link and
modulation method than what you describe. I don't know of any
off-the-shelf solutions that will give coverage you require with
reasonable quality. A custom solution may work.


** See my post for that line of thought.


More details on the application are required.


** But don't expect credible ones from the OP.
