Barcode scanners are typically used in retail, logistics, and warehouse environments to transmit small amounts of data (e.g., scanned UPC codes) to backend systems. Therefore, their throughput requirements are minimal.
From CWDP-305:
“Barcode scanners and similar IoT devices typically transmit small packets at low intervals and have very low throughput requirements. WLAN design for such devices should focus on coverage and roaming, not capacity.”
