4-23 Wireless Considerations
Make the following considerations when an AMR is communicating with a wireless network.
It is recommended to use wireless network industry best practices to conduct a comprehensive work-
space survey and test your wireless service before AMR configuration and operation begins.
4-23-1
Signal Availability
The wireless network should provide constant service throughout the workspace. Consider the follow-
ing signal availability requirements.
• If you have an AMR fleet, constant access is an operational requirement. For a single or segregated
AMR's, partial signal coverage might be acceptable in workspace areas where you do not need to
send commands or receive status from the AMR.
• A signal strength of > -40 dBm is the ideal wireless signal strength. A signal strength of -60 dBm is
the recommended minimum.
4-23-2
Bandwidth
All devices that access a Wireless network consume its bandwidth. The greater the number of AMR's
in your fleet, the more wireless resources they consume.
Additional Information
• Refer to
Fleet Operations Workspace Core User's Manual (Cat. No. I635)
for more informa-
tion about wireless resources.
• The bandwidth usage varies by application. Payload accessories might affect your bandwidth
requirements if they stream data through the AMR’s wireless interface.
Use a dedicated network to restrict wireless network access to AMRs and use security to prevent oth-
er devices from accessing the network.
Typical bandwidth consumption for a fleet is an average 50 Kbps per AMR. This increases when you
connect multiple AMR's to an EM2100 and actively manage them with MobilePlanner. Bandwidth con-
sumption might increase or decrease depending on the types of commands and debugging tools that
you enable in MobilePlanner. Downloading Debug Info Files, uploading ARAM / SetNetGo, and view-
ing the ARAM log on SetNetGo are other examples of functions that may increase bandwidth usage.
The bandwidth consumption is unlikely to exceed 500 Kbps per AMR. A value of 500 Kbps per AMR is
within the capabilities of most wireless access points (>=54 Mbps). If you have multiple access points
with overlapping coverage, this number is less of a concern.

Port Forwarding
Port forwarding can be configured between the USER LAN network and the wireless network. This al-
lows the onboard NX102 controller to send and receive messages via the wireless network. Contact
your local OMRON representative for more information.
