Impinj is working to bring RAIN RFID into more handhelds, rugged tablets and other enterprise devices, with chipset-level support from Qualcomm Technologies and MediaTek.

The US technology company has persuaded Qualcomm to integrate RAIN RFID into its Dragonwing Q-6690 enterprise mobile processor. MediaTek is also backing the push, alongside a device ecosystem that includes AMobile, Bluebird, Chainway, Unitech, UROVO and Zebra, all of which are working on devices that combine RAIN RFID with barcode scanners, cameras, cellular connectivity and business applications.

RAIN RFID uses passive ultra-high-frequency signals to identify, locate and authenticate tagged goods. The technology rests on the ISO/IEC 18000-63 protocol, also known as GS1 UHF Gen2, and is promoted by industry body the RAIN Alliance.

At the centre of the announcement is Gen2X, an Impinj-developed extension to the RAIN RFID standard that the company says improves read speed, range, accuracy and security. Impinj claims that building support directly into chipsets reduces component counts and allows device makers to build smaller hardware.

Performance claims and third-party checks

Impinj separates its own marketing claims from independent verification to a degree. The company said repeat reads can be up to 100% faster with Gen2X. It also cited tests by RFID tag maker Xindeco IoT as supporting its range claims: Xindeco's VersaMini tags, placed 3 millimetres from a large metal surface, were read from more than 1.5 metres away. Impinj claimed this is over 50% farther than tags without Gen2X.

A separate trial covered roughly 800 health and beauty products. From two metres away, Impinj said Gen2X increased the number of items counted in ten seconds by more than 70% compared with the earlier Gen2 standard.

From fixed readers to worker handhelds

The technology is already deployed in shops, warehouses, factories and healthcare facilities to scan stock and track goods. Impinj sees handheld devices broadening those use cases by letting workers collect inventory data while restocking shelves, helping customers or preparing online orders.

Changes in a tag's signal can guide staff to a particular item. For order picking, the devices could direct staff to the correct item, confirm the quantity collected and filter out nearby tags. Chip verification could also help staff check whether goods are genuine.

A representative for Impinj told Mobile World Live that Gen2X is widely deployed across multiple manufacturers on more than 50 RAIN RFID readers, mobile devices and printers — a sign that the extension has already moved beyond pilot-stage adoption.

For Qualcomm, native RFID support in the Dragonwing Q-6690 fits its push into dedicated enterprise silicon rather than repurposed consumer chips. For Impinj, chipset integration removes a barrier that has kept RAIN RFID largely confined to dedicated readers and fixed infrastructure.

The next test will be whether Zebra, UROVO and the other device makers ship combined scanner products at volume, turning Impinj's performance claims into measurable gains in retail and warehouse operations.
