hi steve,

exactly. almost everything is already there. there are some things that
may need to be improved in my opinion:

- deactivating/activating the RACH request
- altering maximum distance (gps) moving off the position of last power
scan, before restarting scanning process.
- multiple radio support for faster scanning and deeper scanning while
moving.
- selecting between the generic text format and PCAP.
- option to wait some more time to receive more system informations than
the mandatory 1..4

regards,

andreas
