``Figure 3 shows with a colour code the distribution of received signal strength from a WLAN access point across the cabin at ear height when using a point antenna (part a) and leaky line (part b) in a simplified aircraft layout; on the left side of figure, the detailed layout can be observed, where the red and green squares represent inactive and active passengers, respectively; the area marked with a red rectangle corresponds to the area plotted in the simplified layout. Observing the simplified layouts, it is obvious that the signal strength is more efficiently distributed using leaky lines provided the sever propagation conditions in a large aircraft. Furthermore, other advantages of applying the leaky line solution are the avoidance of inter-cell interference and the lower cost, since only one antenna is required.``

What is your assessment here...I`m not familiar with leaky line.

To obtain a better spread of 2.4 within the cabin(as I note common laptop usage)...is it to mean one antenna stretched the length of the aircraft with leak points?

At what we have been told..

it`s not what WENCOR will be coordinating....their going to push 802.11A in the 5GHz band....and that when the aircraft is empty.
