Wireless Considerations
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.
Make the following considerations when an AMR is communicating with a wireless network. Refer to
2-4-18 Wireless Specifications on page 2-24 for more information.
4-26-1
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.
AMRs should have a dedicated network separate from public traffic.
• Do not obstruct the wireless antenna areas with metal or other objects that can degrade the signal.
Refer to 1-2 Features and Components on page 1-6 for more information about the location of wire-
less antennas.
4-26-2
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 a Fleet Manager and actively manage them with MobilePlanner. Bandwidth
consumption might increase or decrease depending on the types of commands and debugging tools
that you enable in MobilePlanner. Downloading Debug Info Files and viewing log files 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.
