Nomad RFID Reader Design Guide Introduction This guide provides useful information for developers of applications for the Nomad when equipped with the UHF RFID reader. Coexistence with other RF-based functions When the UHF RFID reader is actively scanning, there is no impact to the following services: • • • Bluetooth (BT) WiFi GPS WWAN is operational while an RFID scan is active, but the maximum data transfer rate has been found to be reduced by 25%.
The average power consumption can be reduced significantly if the RFID reader is activated periodically rather than continuously. For example, if the reader is configured to search for tags for only 5 seconds every 3 minutes, the average additional power consumption due to RFID services drops from 2.7 W to 0.1 W.
