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.

Chainway UR4 industrial mailako RFID gailu bat da. 865-868 MHz / 920-925 MHz / 902-928 MHz tartetan funtzionatzen du eta EPC Global UHF C1 Gen 2, ISO 18000-6C estandarra onartzen du, enpresa logistika aplikazioetan zabalki hedatua.
IP53 babes-mailarekin, biltegi edo txikizkako saltokien atzeko eremuetako ingurumen-baldintzen aurkako babesa eskaintzen du. Irakurgailuak PoE (optional), DC erabiltzen du etengabeko errendimendurako, eta adierazitako irakurketaren abiadura maximoa 1,300+-n dago.
Gaur egungo ezarpenean, sare integratzea oztopo esanguratsuena da. Modelo honek RS-232, RJ45, PoE (optional) aukerak eskaintzen ditu datuak sistema zentraletara transferitzeko.
Hala ere, Chainway hardware zaharretako botil lehergarri nagusia SDK jabetzakoetan (LLRP bezala) edo middleware IoT garestietan oinarritzea da, tag datu gordinak negozio adimen esanguratsuan prozesatzeko.
zure ingeniaritza-taldea Chainway UR4 ebaluatzen ari bada, Nextwaves NR155-ek hodeian oinarritutako arkitektura nabarmen hobea aurkezten du. Sistema zaharren berez ezinbesteko gastu handia bultzatzen dute saltzaileen blokeoaren eta software jabetzako ekosistemaren bidez.
Nextwaves-ek oztopo hau erabat ezabatzen du API MQTT REST estandarra zuzenean gailuan emanez. Zure software-garatzaileek tag irakurketa zuzenean integratu ahal izango dute zure ERP edo WMS atzealde pertsonalizatuan egun batzuen buruan hilabeteen ordez, middleware lizentzia errepikariak erabat saihestuz.

These answers help purchasing and engineering teams review cost, integration, and deployment risk.
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.
