Run Tag Logic at the Read Point, on 4 or 8 Channels
A 2.0GHz quad-core host, 4 or 8 antenna ports, and a 1300+ tags/sec read rate.
The U300 is a fixed UHF RFID reader for read points that stay in one place: a doorway, a lane, a shelf, a line station. Receive sensitivity is listed at < -84dBm and output power at 1W (30dBm), adjustable across +5~+30dBm. Two configurations share the same 247 x 151 x 35mm aluminum alloy body, one with four antenna ports and one with eight. The engine is based on Impinj E Series chips and supports Impinj Gen2X, while Android 11 runs on a Quad-Core 2.0GHz CPU with 2GB + 32GB memory, so filtering and business rules run on the reader itself.

Overview
A fixed reader earns its place by never moving: it is bolted above a door, beside a conveyor, or under a shelf, and it has to keep counting for years without anyone touching it. The U300 is built for that job. One aluminum alloy host, 247 x 151 x 35mm, carries a Quad-Core 2.0GHz CPU, 2GB + 32GB of memory and either four or eight 50Ω antenna ports.
What sets this host apart is how much of the work stays on it. The read rate reaches 1300+ tags/sec, receive sensitivity is listed at < -84dBm, and output power runs 1W (30dBm) with +5~+30dBm adjustment, or 2W (33dBm) as an option. Because Android 11 runs on the host, tag filtering and port switching can execute at the read point, and the network sees results instead of raw reads.
The RFID engine is based on Impinj E Series chips and supports Impinj Gen2X. Integration uses the CedaGlo Software Development Kit in Java, built with Eclipse or Android Studio, and the host exposes 1 x RS-232, 1 x RJ45, 1 x USB Host, 1 x USB Device, HDMI Type A and four isolated input plus four isolated output optocouplers. Power arrives as DC (24V), POE (802.3af 13W) or POE+ (802.3at 25.5W). Explore the full range of fixed RFID readers.

A Closer Look at the Hardware
Two edges, two jobsThe antenna ports occupy the top edge on their own. Everything else lines up on the bottom edge: the GPIO terminal block, 1 x RS-232, HDMI Type A, 1 x USB Host, 1 x USB Device, 1 x RJ45 and the DC input. RF cable and data cable leave the host in opposite directions, so a cable tray runs along one side only.
One indicator per channelThe front panel carries a numbered indicator for every antenna port, 1 through 8 on this configuration and 1 through 4 on the other. A technician standing under the portal can see which port is active without opening a laptop or reading a log.
Flat back, slotted flangesThe back of the Aluminum Alloy host is flat, and a slotted flange sits on each side. The slots take the bolts, so the reader sits against a wall, a column or a gantry plate with nothing protruding behind it. Air Cooling means no vent stack to keep clear.

Why Buy the U300 From CedaGlo
Components You Can Verify
The engine is based on Impinj E Series chips and supports Impinj Gen2X. Both facts sit in the specifications above, in the same words the component vendor uses, so your engineers can check them before a purchase order exists.
Configured Before It Ships
Channel count, the optional 2W output and the antenna choice are decided at order time, not on your dock. We build and label each host to that order, so the box arriving at the site matches the read point it was bought for.
Trial Units Before Volume
Install a single host on the doors that actually matter, with your own tags and your own middleware. If the counts do not hold up under real traffic, the pilot stops there and nothing further is committed on either side.
Serviceable for the Long Run
Spare hosts, antennas and cables come from the same supply that shipped the first unit. Warranty length, spare part years and the return process are confirmed in writing with each order, rather than promised on a web page.
Frequently Asked Questions
How fast can the U300 read tags?
The configuration sheet lists a fastest read rate of 1300+ tags/sec and a receive sensitivity of less than -84dBm. Those figures describe the RFID engine, which is based on Impinj E Series chips and supports Impinj Gen2X. What a given site counts also depends on tag model, antenna gain, cable loss and how the tags move through the field, so run a trial at the read point before sizing the installation.
Should I order the 4 Channel or the 8 Channel host?
Count the antennas the read point needs. The 4 Channel host drives four 50 ohm RP-TNC Female ports and weighs 1366g / 48.22oz for the host only, and the 8 Channel host drives eight and weighs 1528g / 53.90oz. Nothing else changes between them: the same Android 11 platform, the same engine, the same interfaces and the same output power range, so one software image covers both.
What is inside the reader?
The RFID engine is based on Impinj E Series chips and supports Impinj Gen2X. The host runs Android 11 on a Quad-Core 2.0GHz CPU with 2GB + 32GB of memory. Integration uses the CedaGlo Software Development Kit in Java, built with Eclipse or Android Studio, and the host exposes 1 x RS-232, 1 x RJ45, 1 x USB Host, 1 x USB Device and HDMI Type A with 720p HD video output.
How long can I keep buying and servicing this model?
Production life, spare part supply and the return process are confirmed in writing with your order. What this page can state is technical: the U300 runs on standard interfaces, 10/100 Base-T Ethernet on RJ45, RS-232 at 115200bps, USB Host and USB Device, so an integration written against it does not depend on a proprietary link that only one supplier can service.
How much environment can it take?
The configuration sheet lists an operating temperature of -25 degrees Celsius to 65 degrees Celsius, a storage temperature of -40 degrees Celsius to 85 degrees Celsius, and humidity of 10% to 95%. The body is Aluminum Alloy and the cooling mode is air cooling. No ingress protection rating is listed on the sheet, so for washdown areas or outdoor mounting, plan an enclosure.
How is the reader maintained after installation?
Each antenna port has a numbered indicator on the front panel, and the reader reports RSSI, an antenna detector result and an ambient temperature reading, so a loose connector or a failing cable shows up as data instead of as a missing count. Application and firmware updates reach the host over the RJ45 port or over IEEE802.11 b/g/n.

Both versions run one Impinj E Series engine and one Android 11 build on a Quad-Core 2.0GHz CPU; only the channel count and the weight change.
