I am using XBEE PRO S2B module series.I am not able to get range 1.2 Km as mentioned in datasheet. I am getting only 160m with no data loss at line of sight. My instrument is Battery powered(3V,5000mAH). I have also tested it in boost mode at power level 4, still it failed to work. Can there be any environmental interference? Kindly suggest best possible way to improve range.
Thank You
