Min. Distance Between NetBotz USB Coordinators

[aashraf]

Dears,

In one of our projects, We have 30 NetBotz-250 with 25 wireless Temp/RH sensors configured per each NetBotz.
The customer installed each 10 NetBotz in one rack.

We have a repeated issue of sensors inactivity on DCE, Specially for the sensors which are far from the NetBotz (But still within 50 ft).

Based on the below attached screenshot the min. recommended distance between wireless devices is 2 ft (60 cm).
So, I'm asking about the min. recommended distance between the coordinators which are directly connected to the NetBotz USB port.

ideally in a mesh network, the netbot 250/usb coordinator should be in the center of its specific wireless sensors.  I would highly recommend the customer redistribute all of the netbotz 250 so they are distributed evenly throughout the data center.  This will improve communication and prevent excessive battery wear on the sensors closest to the units.

Also make sure the coordinator and wireless sensors are running the latest firmware.  They can be updated using this utility

I realize i didn't answer your specific question, but in my opinion the initial configuration of having all 10 netbotz in the same rack goes against wireless mesh best practices and should be avoided in the first place.  If they correct this, they should see improved wireless sensor communication.
