Maximum devices in a Zigbee mesh network

Hi all....

 

   What is the maximum no of devices in a Zigbee network. Can one have multiple Coordinators linked to one central coordinator in a Zigbee mesh network. We are in a requirement to communicate around 23000 devices. As per my study and based on online articles I found that theorotically it is limited to the addressing method used. So if I am using 16 bit addressing then its 65535 devices. But practically not more than 200 devices because of the latency involved in relaying a packet to the destination. Why does so. is it the limitation at the Zigbee pro stack lebel or the Lack of SOC resources like RAM.....

 

Please guide me on this....

 

Regards,

Harshit

    Have you tried searching for existing answers to your question? I searched for "maximum devices" and "maximum hops" and got lots of hits - then the threads lead to others, and so on. Basically the answer to your question is yes - all of those things and more limit the maximum number of devices achievable / practical / functional / etc. The long answer to the question could take one or two Ph.D.'s. So as with any huge engineering problem, you divide and conquer - and following some threads you will learn that you can break down your target of 23K devices in many PAN's over many channels and so forth.
