1. Separating two read zones
Situation: A wall or a partition physically separates two spaces, but RFID reads can extend beyond that separation. What must be controlled: Create a continuous RF separation to limit reads from one zone into the other. Relevant solutions: Walls, ISO 3 and ISO Paint 26. ISO 3 for surfaces suitable for a wallcovering; ISO Paint 26 for surfaces, relief and geometries suitable for paint application. Continuity of the separation remains the determining principle.
2. Treating an opening or a passageway
Situation: An opening interrupts the separation between two zones, but must remain usable for people, equipment or goods to pass through. What must be controlled: Maintain continuity of the RF separation while keeping the passage usable. Relevant solutions: Openings and passageways, ISO 710.
3. Preserving a transparent area
Situation: A separation must retain a viewing area or allow light through. What must be controlled: Preserve a viewing area while controlling RFID reading through a transparent surface. Relevant solutions: Transparent surfaces, ISO 325 and ISO 711. ISO 325 treats existing glazing. ISO 711 creates a rigid viewing area in a door, a partition or an enclosure.
4. Containing a read volume
Situation: Reading must remain limited to a carton, an enclosure or a defined volume, without picking up the tags around it. What must be controlled: Define an RF boundary around the volume to keep reads within the intended zone. Relevant solutions: Enclosures and read zones, ISO 13 and Custom design. The reverse principle is also covered: preventing contents from being read from the outside.
Situation: In a metallic environment, RF reflections can interfere with reading in the read zone and make its behaviour difficult to control. What must be controlled: Reduce the RF reflections that interfere with reading. Relevant solutions: Technical materials, ISO 52. Used in particular inside a metal volume or near or in contact with a conductive surface.
