The Zebra ET401 is a rugged 10-inch Android tablet built for field service, delivery and warehouse workers who need a durable, connected device rather than a consumer tablet. This variant adds 5G cellular connectivity for constant connection outside Wi-Fi coverage, plus an SR500 integrated scan engine — a dedicated long-range 2D barcode imager built into the tablet, letting a worker scan without a separate handheld scanner. It runs Android with Google Mobile Services (GMS) certification on 8GB RAM/128GB storage, and 'ROW SKU' indicates this is the Rest-of-World regional variant (radio bands/certifications tuned for markets outside the US). Standard Zebra ruggedisation (drop/dust/moisture resistance) is typical of this class though not itemised in the listing itself.
