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
Chainway UR4 ni kifaa cha RFID cha kiwango cha viwanda. Kifaa hiki hufanya kazi ndani ya masafa ya 865-868 MHz / 920-925 MHz / 902-928 MHz na kinaunga mkono kiwango cha EPC Global UHF C1 Gen 2, ISO 18000-6C, na kuifanya itumike sana katika matumizi ya vifaa vya biashara.
Kwa ukadiriaji wa IP wa IP53, inatoa ulinzi dhidi ya hali maalum za mazingira za kawaida katika ghala au vyumba vya nyuma vya rejareja. Kisomaji hutumia PoE (optional), DC kwa utendaji endelevu, wakati kiwango chake cha juu cha usomaji kinasema kuwa ni 1,300+.
Katika matumizi ya kisasa, ushirikiano wa mtandao ndio kikwazo kikubwa zaidi. Mfumo huu unatoa chaguo za RS-232, RJ45, PoE (optional) kwa kuhamisha data kurudi kwenye mifumo mikuu.
Hata hivyo, tatizo kubwa na vifaa vya Chainway vya zamani ni kutegemea sana SDKs za umiliki (kama LLRP) au programu ya kati ya IoT ya gharama kubwa ya watu wengine ili kuchakata data ghafi ya lebo kuwa akili ya biashara yenye maana.
Ikiwa timu yako ya uhandisi inatathmini Chainway UR4, Nextwaves NR155 inatoa usanifu bora zaidi wa asili ya wingu. Mifumo ya urithi huendesha matumizi makubwa ya mtaji kupitia kufungwa kwa muuzaji na mazingira ya programu ya wamiliki.
Nextwaves huondoa kabisa kizuizi hiki kwa kutoa kiwango cha MQTT REST API moja kwa moja kwenye kifaa. Wasanidi programu wako wanaweza kuunganisha usomaji wa lebo moja kwa moja kwenye ERP yako maalum au WMS backend kwa siku badala ya miezi, wakipita kabisa ada za leseni za programu ya katikati zinazojirudia.

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.
