``The network uses a single standardised connection point for all wireless devices and just one antenna (the `Leaky Line`) inside the cabin for data distribution.``

That pretty much describes any 802.11g/b wireless single antenna access point router.

Is it a proprietary 2.4Ghz ?

I doubt it....``standardised``(standardized) tells me its 802.11

Get ready for the smoke....if not smoke.. the details should have more explination.
