x-ctu scan time

Hi,
in xbee S8 (or) xbee 868/865 module how much fast we can able to scan the network. for example 50 nodes is in the network all in the broadcast mode. how much time it will take to scan the total network. is there any setting need to change for getting less time to scan the network.

please suggestion solution any one for this as early as possible.

What do you mean by Scan network? Do you mean how long it will take to collect or poll data from each node?

i mean how much time it will take to collect the data from each node.

which XBee 868 product are you referring to? The high powered XBee PRO 868 or the 868 LP?
