Scan Channel on Xbee S2C

0 votes
Hello everybody,
I have a research about N-Channel Zegbee to improve its throughput, some study have discussed it
like :
Xing Xu used Micaz and Tole for improvement the throughput with make small center frequency channel.

Xbee have channel mask, which define the channel 11-26 with channel bandwidth 5MHz.
for Example:
channel/mask : 0x7FFF --> 0111 1111 1111 1111 (just 26nd channel isnt active active ).

Decimal Hex Frequency SC mask WiFi Conflict Comments
11 0x0B 2.405GHz 0x0001 Overlaps Ch 1 Newer XBee only
12 0x0C 2.410GHz 0x0002 Overlaps Ch 1
13 0x0D 2.415GHz 0x0004 Overlaps Ch 1
14 0x0E 2.420GHz 0x0008 Overlaps Ch 1
15 0x0F 2.425GHz 0x0010 Overlaps Ch 6
16 0x10 2.430GHz 0x0020 Overlaps Ch 6
17 0x11 2.435GHz 0x0040 Overlaps Ch 6
18 0x12 2.440GHz 0x0080 Overlaps Ch 6
19 0x13 2.445GHz 0x0100 Overlaps Ch 6
20 0x14 2.450GHz 0x0200 Overlaps Ch 11
21 0x15 2.455GHz 0x0400 Overlaps Ch 11
22 0x16 2.460GHz 0x0800 Overlaps Ch 11
23 0x17 2.465GHz 0x1000 Overlaps Ch 11
24 0x18 2.470GHz 0x2000 Overlaps Ch 11 Newer XBee only
25 0x19 2.475GHz 0x4000 No Conflict Newer XBee only
26 0x1A 2.480GHz 0x8000 No Conflict Newer non-PRO XBee only

This tabel describe the channel deatil of zigbee or xbee.

The question:
Can the configuration a on xbee be changed , even though I want to explore the channel on xbee?
i just knew about the configuratin channel xbee, using the bitfield of xbee. May be there is any button that i stiil dont know which need configuration.?

Thank you

Sure you can. Just change the CM command on all of your nodes and then issue a Global network reset.

The Operating channel is just that.  The channel in which the module is operating on. Where by the Scan Channel is a Channel Mask that the radio can scan and try to find the coordinator operating on and form a network on.

When changing channels or channel masks on the Coordinator, you must make the same changes or corresponding changes on the end device or router.

You need to be careful not the set your coordinator on a channel in which the end device or a lower power module does not support or they will not be able to communicate.
i'm back again..
can they (refers to 3 device Xbee) communicate each other on different channel?

First Xbee as coordinator create operating channel D
Second Xbee as Router join the network of coordinator, so it means Router use channel D

the third Xbee as end device used other channel which differ with coordinator, can it happen?

i just want to explore multiple channel that can use on Zigbee or Xbee?

Please help me
No, they all need to be on the same channel.
the same channel means operating channel, right?
let me clarify it
operating channel is like channel they can communicate each others, whereas scan channel for connect to coordinator

am i right?
Yes, they would all need to be on the Same Operating channel. The Scan channel just tells the nodes which channels to find the coordinator on. The SC for the coordinator tells the coordinator which channels it can select from to start the network on.
