You can have an array of hash refs instead.

@clients = (
    { MAC => $mac, RSSI => $rssi, SNR => $snr }, /* 0 */
    { MAC => $secondmac, RSSI => $secondrssi, SNR => $secondsnr }, /* 
+1 */
    /* etc */
);

Then you can grab the bits like

%client_0 = %{$clients[0]};

etc.

To build it on the fly, you'd have code like:

my @clients;

# The whole hash at once
$clients[0] = { MAC => $mac, /* ... */ };

# Or setting individual bits
$clients[0]->{MAC} = $mac;

This is pretty well covered in the documentation, such as in perlreftut and perldsc.
