Hi, in my project I need long distance wireless.
I use two xbee pro 802.15.4. One is sending node, and the other one is receiving node(Xbee +Spider main board).
The sending node is embedded in a 2mm thickness PVC tube with 3dbi antenna.
The receiving node use a 5dbi antenna.
I test the distance outside in open space, but the max distance is near 160m.
Far from my desire distance(1000m),and the datasheet of Xbee pro.
So, how to improve it?
Use higher Gain antenna both in two nodes?
Appreciate for any suggestion.
