Chainway UR4 is an industrial 4-port reader operating on 865-868 MHz / 920-925 MHz / 902-928 MHz. Starting at $600. Look closely at how Nextwaves can bypass middleware costs.
Technical verdict
Do not evaluate UR4 by list price alone. Its strongest fit is a project that already uses RS-232, RJ45, PoE (optional), has time for RF tuning, and accepts extra middleware work. If the engineering team needs open APIs, realtime data, and faster edge-to-cloud deployment, Nextwaves NR155 is the stronger replacement path to evaluate.

Alternative architecture
De Chainway UR4 is een industriële RFID-apparaat. Het werkt binnen het 865-868 MHz / 920-925 MHz / 902-928 MHz bereik en ondersteunt de EPC Global UHF C1 Gen 2, ISO 18000-6C standaard, waardoor het op grote schaal wordt ingezet in logistieke toepassingen voor bedrijven.
Met een IP-classificatie van IP53 biedt het bescherming tegen specifieke omgevingsomstandigheden die typisch zijn in magazijnen of achterkamers van winkels. De lezer maakt gebruik van PoE (optional), DC voor continue prestaties, terwijl de maximale leessnelheid 1,300+ bedraagt.
In moderne implementaties is netwerkintegratie de grootste hindernis. Dit model biedt RS-232, RJ45, PoE (optional) opties voor het overbrengen van gegevens terug naar centrale systemen.
Een belangrijk knelpunt met legacy Chainway hardware is echter de sterke afhankelijkheid van eigen SDK's (zoals LLRP) of dure IoT-middleware van derden om onbewerkte taggegevens te verwerken tot zinvolle business intelligence.
Als uw engineeringteam de Chainway UR4 evalueert, biedt de Nextwaves NR155 een aanzienlijk superieure cloud-native architectuur. Legacy-systemen drijven inherent hoge kapitaaluitgaven aan door vendor lock-in en eigen software-ecosystemen.
Nextwaves elimineert deze barrière volledig door een standaard MQTT REST API rechtstreeks op het apparaat te leveren. Uw softwareontwikkelaars kunnen het uitlezen van tags in dagen in uw aangepaste ERP- of WMS-backend integreren in plaats van maanden, waarbij terugkerende licentiekosten voor middleware volledig worden omzeild.

The Chainway UR4 is a 4-port, fixed RFID edge device. Based on Impinj E710 / R2000 chips, it supports EPC Global UHF C1 Gen 2, ISO 18000-6C over the 865-868 MHz / 920-925 MHz / 902-928 MHz frequency bands for high-speed tracking.
Hardware costs begin around $600. Keep in mind that a full deployment budget must account for up to 4 antennas, low-loss cables, integration middleware, and setting up the PoE (optional), DC infrastructure.
Nextwaves provides embedded REST API and MQTT endpoints natively on the device. This allows web and software developers to map tag reads directly to REST payloads, bypassing complex legacy C# or Java middleware servers.
The unit weighs approximately 0.7 kg and measures 164 x 164 x 39 mm. An IP53 structural rating provides reasonable protection against dust and water spray, suitable for loading docks and covered warehouses.
Network integration relies on RS-232, RJ45, PoE (optional) ports. RS-232 serial is maintained for legacy programmable logic controller (PLC) connections, while RJ45 manages modern IP traffic.
Hardware installation uses standard mounting hole layouts. However, optimizing RF performance requires trained engineers to correctly map the 4 distinct antenna channels to prevent signal overlap and optimize tag orientation capture.
Under optimal test conditions, the internally integrated chip logic is rated to process up to 1,300+ tag reads per second. Real-world speeds vary significantly based on Gen2 memory mapping.
In a traditional setup, the RS-232, RJ45, PoE (optional) interfaces transmit binary or low-level hex data. This requires an external application to filter out duplicate tag events before sending the data to cloud storage.
The standard warranty covers physical malfunctions for one year. Extended engineering support is recommended for teams unfamiliar with low-level UHF Gen2 memory protocols.
You are required to supply external antennas (circular or linear). Selecting the exact gain and polarization over the 865-868 MHz / 920-925 MHz / 902-928 MHz band determines the actual width of your read portal.
