It is usually called nomad, because it is not really
mobility.

With 802.11, you can connect to an AP and, if the AP
fails, you may be connected to another AP, but the
transition takes considerable amount of time not
tolerable for voice communication, which is why it
is not called mobility.

If you want mobility, have different SSIDs for APs in
the same frequency band (or, let terminals have multiple
sets of radio interfaces) and let terminals connect
to multiple APs simultaneously.

Then, run mobile IP to *RAPIDLY* control the primary
AP depending on signal quality of beacons from APs.

Though you only have to modify software on terminals,
AFAIK, there is no such commercial products.

With your environment, you only need indoor equipments with
external antennas located outdoors.
