Long-Range UHF RFID Readers in India: Read Ranges, Prices and Where Each Fits

Which UHF readers list a read range of 10 m or more?

Each range below is the read-range row from the product page, as the page states it.

Why the tag usually sets the range

A reader's listed range is a best case: a suitable tag, a good antenna, clear air and correct mounting. The tag you fix on the vehicle, pallet or asset has its own listed range, and the shorter of the two is what you get. Some examples from the catalogue:

• The ID-1993-H9 car windshield label (₹6 + GST) reads up to 6 m, depending on the reader antenna, the glass and the environment.
• The IDTS-UTWTH3 tamper-proof windshield label (₹25 + GST) reads over 8–10 m when fixed inside the windshield.
• The IDTS-UPT pallet tag (₹45 + GST) reads up to 12 m at 2 W ERP, India's limit.
• The Encore on-metal tag (₹45 + GST) reads up to 20 m, depending on the reader.

A gate that must identify cars at 10 m therefore needs a tag listed for that distance as well as a reader. Check both before you order, and trial one lane or one dock door first. Our read-range calculator gives a first estimate for your set-up, and the read-range link budget guide explains the arithmetic.

India's power limit and higher-gain antennas

In India, UHF RFID readers work in the licence-exempt 865–868 MHz band under G.S.R. 853(E) of 2021, which allows a reader up to 2 W e.r.p. on four 200 kHz channels. Antenna gain counts towards that limit. Once a set-up is at 2 W e.r.p., moving from a 9 dBi to a 12 dBi antenna means turning the reader down by the same 3 dB, so the practical gain in range is smaller than the antennas' listed figures suggest; what changes most is the beam, which is narrower at 12 dBi and suits a lane or a long aisle.

Our 9 dBi circular antenna (₹8,000 + GST) lists up to 25 m and the 12 dBi circular antenna (₹11,000 + GST) up to 30 m, each with an Identium UHF 4-port reader. These are the antennas' listed figures; at India's 2 W e.r.p. limit the gap between them narrows, so choose on beam width and test on site. The 9 dBi vs 12 dBi comparison sets them side by side. Each reader model also needs WPC Equipment Type Approval, and each product page shows its BIS and WPC approval where it has one.

Long-range readers for vehicle gates and boom barriers

At a gate the reader must also tell the barrier to open, so look at the trigger and relay as well as the range. The IF9C has a trigger work mode and a relay, the IF9A has an optional relay, and the IHZ4 has three inputs and three relay outputs, so one IHZ4 with external antennas can serve an in lane and an out lane. The IF9A vs IF9C comparison sets the two integrated readers side by side. For a residential gate, the housing society guide lists what one lane needs, and the vehicle RFID tag guide covers windshield tags and FASTag.

Long-range readers for warehouses, dock doors and yards

For dock doors and portals, a fixed reader drives external antennas. The IHZ4 has 4 antenna ports, the IDTS-IHZ8 and IDTS-IHZ16 have 8 and 16 for multiple lanes, long conveyors or full-height pallet portals, and the IDTS-IHZ4N, IDTS-IHZ8N and IDTS-IHZ16N are 4-, 8- and 16-port readers listed up to 20 m. The IHZ4 vs IHZ8 vs IHZ16 comparison shows what changes with the port count, and the IHZ4 vs IHZ4N comparison sets the two four-port readers side by side.

For yards and walk-around counts, the CX1500N handheld and the CX806T tablet list up to 25 m, and the ID-SL15 sled turns a phone into a reader listed up to 16 m; the UHF handheld reader price guide compares them. Integrators building their own enclosure can use the ICL4P and ICL8 reader boards, listed up to 20 m, or the one-port ICL1P, listed up to 15 m. Every reader is under RFID readers, and the reader buying guide covers ports, interfaces and IP ratings.
