Learn how to use radio frequency-enabled mobile scanning devices in your day-to-day warehouse operations to improve efficiency and throughput, increase data accuracy, and boost storage capacity and warehouse organization.
Key Concept

The SAP Logistics Execution System provides support for data entry using radio frequency (RF)-enabled mobile scanning devices. Typical RF devices are handheld terminals, barcode scanners, and truck-mounted terminals. RF uses barcodes for receiving goods, putaway, posting, bin-to-bin movements, and inventory counting. RF uses an extended wired local area network and has three primary components – a mobile RF scanner, a base station, and a network controller connected to a server holding some kind of a database application. The location and number of access points can vary depending on various factors, such as the warehouse size and layout. Data is usually entered either by scanning barcode labels or using a keyboard or touch screen.

The modern warehouse is cable-free with paperless receiving, putaway (i.e., transferring material from the goods receipt interim storage area to the appropriate storage types), picking (i.e., taking goods from a storage location in the right quantity for shipping), and inventory counting. SAP integrates various warehousing functions in the SAP system through radio frequency (RF). 

The following is a scenario of our successful implementation of RF at a major telecom company. Though this implementation was done for a telecom industry, the same solution can be used for inbound receiving of material in any RF-enabled warehouse.
