Helped test a RF4CE (ie Zigbee consumer subset, a 802.15.4 radio) remote control. Went over 400 feet in a parking lot without any failures. That's nearly a tenth of a mile! We stopped testing. But it was fine at 400 feet. Tested inside, saw crazy results. More power more problems esp. with transmitter orientation as a factor. A 400 foot RF remote is probably a dual use item. Jus sayin.
