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.

Deployment review
Fixed UHF RFID projects that already use RS-232, RJ45, PoE (optional) and have time for RF tuning.
Do not compare device price only; total cost depends on accessories, software, and integration.
IP53, PoE (optional), DC, 164 x 164 x 39 mm, and 0.7 kg must match the site layout.

Alternative architecture
Chainway UR4 je RFID uređaj industrijskog kvaliteta. Radi u 865-868 MHz / 920-925 MHz / 902-928 MHz opsegu i podržava EPC Global UHF C1 Gen 2, ISO 18000-6C standard, što ga čini široko primenjenim u logističkim aplikacijama preduzeća.
Sa IP rejtingom od IP53, nudi zaštitu od specifičnih uslova okoline tipičnih za skladišta ili zadnje prostorije maloprodaje. Čitač koristi PoE (optional), DC za kontinuirane performanse, dok je njegova navedena maksimalna brzina čitanja na 1,300+.
U modernim implementacijama, mrežna integracija je najveća prepreka. Ovaj model nudi RS-232, RJ45, PoE (optional) opcije za prenos podataka nazad u centralne sisteme.
Međutim, glavno usko grlo sa zastarelim hardverom Chainway je velika zavisnost od vlasničkih SDK-ova (kao što je LLRP) ili skupog IoT softvera treće strane za obradu sirovih podataka o oznakama u smislene poslovne informacije.
Ako vaš inženjerski tim procenjuje Chainway UR4, Nextwaves NR155 predstavlja znatno superiorniju arhitekturu zasnovanu na oblaku. Nasleđeni sistemi inherentno pokreću visoke kapitalne izdatke kroz zaključavanje dobavljača i vlasničke softverske ekosisteme.
Nextwaves u potpunosti eliminiše ovu barijeru obezbeđivanjem standardnog MQTT REST API direktno na uređaju. Vaši softverski programeri mogu da integrišu čitanje tagova direktno u vaš prilagođeni ERP ili WMS backend za nekoliko dana umesto meseci, u potpunosti zaobilazeći ponavljajuće naknade za licenciranje softvera.

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.
