XBEE PRO serie 2.5 Indoor/Urban: 30 meters

Hi

20 days ago I acquired four XBee pro, on a XBee installed the firmware of coordinator, the other three as device / router, I tested and works perfectly, but the distance Indoor / Urban reaches about 30 meters and Outdoor line-of- sight reaches about 100 meters. What should I set up or should I make the XBee to reach the distances that say in the technical specifications of 100 meters in

Indoor / Urban Outdoor and 1600 meters in line-of-sight??

Thanks a lot

I have only experience with XBee Pro series 1, not 2.x. I’ve achieved 1/3 to 1/2 mile with a gain omni on one end (U.FL antenna connector on XBee).

With chip (on PCB) antennas, the range is far less of course. The little “wire” antenna works much better than the chip antenna.

I can’t recall, but the series 2.5 has about the same transmitter power as does series 1, right? This is about 60mW.
