Increase the range of my zigbee network - help

Hi,

My objectif is : create a solid zigbee mesh networking with multiple xbee PRO module.

I have made an application in c # to monitor the traffic on my network Zigbee (Coordinator API mode). I wrote myself a library to analyze the data frames.

I can send and receive commands, send messages, broadcast messages / commands, etc…

So it works!

But I can not extend the range of my XBEE PRO zigbee network.
All my routers are connected directly to my coordinator.
My routers have no parent (0xFFFE). My “end devices” have parents (routers or coordinator with 0x0000).

Unfortunately, if I increase the distance between my coordinator and my group of routers I can no longer communicate with some other routers of my network… Sometimes I have a link with one router but i cannot communicate with a other one router close to the first one with whom I communicate.

I feel that my network is not a “MESH” network but a “STAR” network configuration.

I certainly have misconfigured my XBEE modems but I can not solve this problem. Maybe you can help me?

Here’s my configuration for my coordinator and one of my routers :

Thank you. :slight_smile:

make sure you’re using PRO radios. you’ll get better range that way.
