My setup has the projector located back approx. 17 feet from the front of the screen. So the signal would have to go that far and then bounce back at least another 13 feet to reach the back seats.
[EDIT]: I think I found the answer to my above question. From the Panasonic web page:
"The PT-AE7000/AT5000 comes equipped with a built-in transmitter with maximum transmission distance of six meters (about 20 feet).* For more range up to ten meters (about 33 feet), an optional infrared transmitter, ET-TRM110 is available for greater installation flexibility.
* The indicated distance between the projector and screen is valid when the conditions described below are satisfied. Also, note that the transmission distance can differ largely due to strong light, such as sunlight and fluorescent lamps, at the installation location or due to the screen type or material.
CONDITION 1: The distance between the screen and the 3D Eyewear (viewing position) is 5 meters to the front of the screen.
CONDITION 2: The screen is 100 inches, measured diagonally, and has a screen gain of 1.
CONDITION 3: The projector is set up in front of the screen, and the lens shift function is not used.
CONDITION 4: The [3D IR TRANSMITTER] setting in the main unit is set to [STRONG]."
If I'm reading this correctly, the built in emitter will reach approx. 6 meters to the screen, and bounce back to within 5 meters assuming the conditions above are met.
