<Purpose>
    Script to help me position my `Alcatel Linkhub HH40v` LTE modem for the
    best signal strength.

    If a change in signal strength is detected, it uses the OS X command line
    tool `say` to say the new signal strength.

<Usage>
    1. Connect your computer to your Alcatel Linkhub's WiFi
    2. Open a browser and go to the admin page at `192.168.1.1`
    3. Open your browser's developer tools, go to the `network` tab and look
       for requests to `http://192.168.1.1/jrd/webapi`
    4. Take any request, copy the value of the header
      `_TclRequestVerificationKey` and assign it to below variable
      `REQUEST_KEY`
    5. Turn up the volume of your computer and run the script
    6. Walk your Alcatel Linkhub around your apartment (long extension cord is
       helpful) and place it at where your computer tells you a high signal.

@spolette can you made python script for MW40V ?
