Four-Port UHF Reading With Android 13 On Board
1300+ tags/sec across four 50Ω TNC ports, with receive sensitivity below -84dBm.
Four TNC ports drive up to four antennas from one enclosure, and the reader accepts a variety of antennas such as 6dBic and 9dBic. The standard configuration transmits 1W at 30dBm and takes power from a single POE drop; the optional 2W configuration reaches 33dBm on POE+ or DC. The RFID engine uses Impinj E Series chips, and Impinj Gen2X is supported. Android 13 runs on an octa-core 2.0 GHz processor with 3GB of RAM and 32GB of storage, inside a 214 x 148 x 30 mm aluminium alloy body that brings RS-232, RJ45, USB and HDMI Type A out to its edges.

Overview
The URA4 is a fixed reader that carries its own computer. A single 214 x 148 x 30 mm enclosure feeds four antennas from its 50Ω TNC ports, while an octa-core 2.0 GHz processor with 3GB of RAM and 32GB of storage runs Android 13 on the unit itself. Filtering and buffering happen where the antennas are, not on a server elsewhere in the building.
The two configurations differ in output power and in nothing else. The standard unit transmits 1W at 30dBm, adjustable from +5 to +30dBm, and draws everything it needs from one POE drop. The optional 2W unit reaches 33dBm, adjustable from +10 to +33dBm, and needs POE+ or DC instead. Every other line of the specification is shared, so both units take the same software image and the same integration work.
Behind the ports, the engine is built on Impinj E Series chips with Impinj Gen2X added, and it reads EPC global UHF Class 1 Gen 2 and ISO 18000-6C tags at 1300+ tags/sec. Wired and wireless links are both present: 10/100 Base-T Ethernet over RJ45, 802.11 a/b/g/n/ac on 2.4G and 5G with 802.11r fast roaming, Bluetooth 5.1, plus RS-232, USB and HDMI Type A for equipment at the reader.

A Closer Look at the Hardware
Finned Aluminium Alloy BackThe whole rear face is one finned aluminium alloy panel, and the cooling mode is air cooling. Four slotted lugs are placed outside the fin area, so the mounting bolts never cross the cooling surface.
Side Ports Under CoversHDMI Type A sits behind the cover on one side and USB behind the cover on the other. Each cover clips flush with the body, so a unit that needs only the network cable leaves both of them closed.
Antennas Up, Cabling DownThe top edge carries the antenna connectors, with the WLAN and 4G positions marked at either end of the row. LAN, RJ45, GPIO, POWER and reset are grouped along the bottom edge instead, so coaxial runs and cable runs leave the body in opposite directions.

Why Buy the URA4 From CedaGlo
Components You Can Verify
Every part name on this page comes from our configuration sheet. Impinj, Android and the 802.11 letters are printed the way their suppliers print them, so you can check each one before you talk to us.
Configured Before It Ships
Tell us which output power the site needs and which band your regulator allows. We set both at our factory, so the unit arrives configured to your specification.
Borrow One Before Committing
Ask for a unit on loan and run it against your own tag population. Read rates depend on the tags and the surroundings, so two weeks on your own racks tells you more than any figure we could print here.
Supported For the Long Run
Firmware and the SDK stay available for hardware you already have in service. Warranty length, spare part supply and the RMA route are confirmed in writing with the order.
From US$629 per unit for 1–9 units in the standard configuration; higher configurations are quoted by our sales engineers. MOQ: 1 unit. The URA4 Fixed RFID Readers is built and tested in-house and quoted per configuration, with distributor pricing for resellers.
Frequently Asked Questions
How many tags per second can the URA4 actually read?
Our configuration sheet lists a fastest read rate of 1300+ tags/sec, with receive sensitivity below -84dBm and RSSI reported on every read. The engine reads 1300+ tags/sec; throughput at your site depends on the tags, the antenna gain and nearby RF sources, and we confirm it with you during evaluation. Borrow a unit and measure it on your own stock before you write any number into a specification.
Which of the two configurations should I order?
Output power is the only thing that separates them. The standard URA4 transmits 1W at 30dBm, adjustable from +5 to +30dBm, and runs from DC 12V or from a single POE drop rated 802.3af 13W. The optional 2W URA4 transmits 33dBm, adjustable from +10 to +33dBm, and needs DC or POE+ rated 802.3at 25.5W instead. Everything else is identical, including the four TNC antenna ports, the engine and the whole platform, so both configurations take one software image.
What is the RFID engine built on?
The engine is based on Impinj E Series chips and supports Impinj Gen2X. It reads EPC global UHF Class 1 Gen 2 and ISO 18000-6C tags across 865-868 MHz, 920-925 MHz and 902-928 MHz. On the computing side the unit runs Android 13 on an octa-core 2.0 GHz processor with 3GB of RAM and 32GB of storage. Each of those names belongs to its own supplier, so you can pull up every datasheet directly.
How long will the URA4 be supported?
Firmware, the CedaGlo Software Development Kit and the Java sample code stay available for units already in the field, and the toolchain is Eclipse or Android Studio, both of which are ordinary Android tooling rather than anything proprietary to this reader. Production life, spare part supply years and warranty length are confirmed in writing with the order.
What operating environment is the URA4 rated for?
Our configuration sheet gives an operating temperature range of minus 25 degrees Celsius to 55 degrees Celsius, a storage range of minus 40 degrees Celsius to 85 degrees Celsius, and humidity from 5% to 95%. The body is aluminium alloy and the cooling mode is air cooling, so the reader runs fanless. Those are our own design figures.
How is the reader managed once it is installed?
Android 13 runs on the reader itself, so your application executes locally and keeps working through a network outage, and the RJ45 port, the WLAN radio and the 4G radio give three separate routes back to the unit. A reset control sits on the bottom edge beside the POWER connector for local recovery. Repair routing, RMA turnaround and spare part terms are confirmed in writing with the order.
Is there a minimum order for the URA4 Fixed RFID Readers?
The URA4 Fixed RFID Readers can be ordered from 1 unit, priced by the configuration you choose, with distributor and volume pricing on request.
Is OEM or private label available for the URA4 Fixed RFID Readers?
Yes. OEM and private-label URA4 Fixed RFID Readers builds cover port count, interface (RJ45, RS-232, Wi-Fi), operating system build, enclosure and labelling, all set at assembly in our Shenzhen factory.
How do you check the URA4 Fixed RFID Readers before delivery?
Before shipment we run interface and network tests, GPIO trigger tests and continuous-read soak tests. Assembly and testing happen in our Shenzhen factory, certified to ISO 9001, ISO 14001 and ISO/IEC 27001.
