Use cases
Tracking tools
Find toolsKeep sets together
Restrict to areas

Location often implies process stageTrack assets or paperwork
Tracking across multiple locationsDistributed manufacturing
Process visibility
Tool configurationConfigure tool settings based on location
Confirm operations carried out

Technology challenges and approaches
Indoor location - RFID
Suitable for some use casesEntrance and exit of assets
Indoor location - RFID
Suitable for some use casesEntrance and exit of assets
Applies to some process flows, but some limitationsLess applicable to tool tracking
Indoor Location - RTLS
Continuous location trackingSparse infrastructure
Very flexibleCommon infrastructure for multiple applicationsUltra Wideband (UWB) most common approach
UWB considerations
TDOA versus AOACommunications channel
Tag density, range, update rateTag form factors, battery life
Intrinsic safetyPresence
GPS integrationSoftware platform and applications
Indoor location - presence
Low infrastructure, low location accuracyFixed or mobile receivers
FOD within wings etcStorage containers
Outdoor locationPrevious options applicable
GPS a useful additionNeed last known location
More costly, power hungryIntrinsic safety
Multi-mode solutionsCommon tag with UWB, presence, GPS
Common infrastructure / software platformControl channel important for switching modes
