Long-range RFID readers for driveways, gates and checkpoints

An integrated long-range RFID reader combines a UHF reader and antenna in a single enclosure. It is mounted above or beside a driveway and reads tags without stopping vehicles or running RF cables to external antennas. The rated maximum read range is 8–15 m, depending on model and conditions. This is the main equipment type used at checkpoints, car parks and gates where a tag on a windscreen or vehicle body must be detected automatically. We select and supply readers for each project based on the driveway geometry, tag type and integration method.

Types of integrated readers

* Rated tag read range under favourable conditions; the actual range depends on the tag, mounting height and environment and is verified by testing.

BizData codes are our designations for standard selection configurations and are confirmed during project estimation.

Common characteristics for this class include the EPC Gen2 / ISO 18000-6C protocol, an integrated circularly polarised antenna with 6–12 dBi gain, adjustable transmitter power, 12 V or PoE power, and an ABS plastic or die-cast aluminium enclosure. Sizes range from compact enclosures (Р1) of approximately 110×56 mm to long-range panels (Р15) measuring 445×445 mm. Passive UHF RFID operates in the 860–960 MHz band, but equipment is produced in regional versions: for Kazakhstan, we select the European ETSI 865–868 MHz version; the FCC 902–928 MHz version is intended for the Americas. For an explanation of the standard and procurement checks, read our article on EPC Gen2 and ISO/IEC 18000-63.

How it differs from a fixed reader with external antennas

A fixed multi-port reader is a controller connected to several external antennas by RF cables. This architecture is used to build read zones on conveyors, large portals and sites with multiple checkpoints. An integrated reader creates one zone but is installed as a single device, with no cable selection or RF losses along the run. It is usually simpler and more economical for a single driveway or gate. If you need several zones or complex geometry, see the overview of RFID readers and RFID portals.

How to choose: 4 criteria

1. Driveway geometry and range. The rated maximum read range is 8–15 m depending on model and conditions. Design calculations account for mounting height, lane width and vehicle speed. Transmitter power is adjustable, allowing the read zone to be narrowed so the reader does not capture tags from an adjacent lane.
2. Tag compatibility. A windscreen tag, a label on the vehicle body and an on-metal tag on the frame read differently. We test each reader-and-tag combination on samples in our laboratory before procurement.
3. Integration interface. Wiegand 26 connects to an access control system as a conventional card reader; RS-232/RS-485 connects to industrial automation; TCP-IP and PoE connect to a network for server-side tracking; digital inputs and outputs (GPIO) control a barrier gate or traffic light.
4. Enclosure design. Outdoor units use IP65 die-cast aluminium or ABS enclosures; compact access readers (Р1) for indoor use are available with IP56 protection.

Typical applications

• Industrial checkpoints and company vehicles. A windscreen tag, an Р15 reader above the driveway, an automatic entry and exit log, and integration with access control and video surveillance. Learn more about RFID for vehicles.
• Car park with a barrier gate. Automatic access for authorised vehicles without remote controls (an Р6 configuration is usually sufficient for a single lane), guest passes, access rights and reports. The solution is described on the RFID for parking page.
• Warehouse and yard gates. Detecting machinery, trailers and returnable containers passing through an opening as part of a warehouse tracking system. For continuous inventory tracking at a gate, an RFID portal is more commonly used.
• Pilot before rollout. We verify read range and stability in your driveway with your tags as part of an RFID pilot project.
