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.
Plan for middleware, SDK work, duplicate filtering, and business-event mapping.
Alternative architecture
Ang Chainway UR4 ay isang industrial-grade na RFID device. Ito ay gumagana sa loob ng saklaw ng 865-868 MHz / 920-925 MHz / 902-928 MHz at sumusuporta sa pamantayan ng EPC Global UHF C1 Gen 2, ISO 18000-6C, na nagiging malawakang ginagamit sa mga enterprise logistics na aplikasyon.
Sa IP rating na IP53, ito ay nagbibigay ng proteksyon laban sa mga tiyak na kondisyon ng kapaligiran na karaniwan sa mga bodega o likod na bahagi ng retail. Ang mambabasa ay gumagamit ng PoE (optional), DC para sa tuloy-tuloy na pagganap, habang ang tinukoy na pinakamataas na bilis ng pagbasa ay umabot sa 1,300+.
Sa mga modernong deployment, ang integrasyon ng network ang pinakamalaking balakid. Ang modelong ito ay nag-aalok ng mga opsyon sa RS-232, RJ45, PoE (optional) para sa paglilipat ng data pabalik sa mga sentral na sistema.
Gayunpaman, isang malaking bottleneck sa legacy na hardware ng Chainway ay ang labis na pag-asa sa mga proprietary SDKs (tulad ng LLRP) o mamahaling third‑party IoT middleware upang iproseso ang raw tag data tungo sa makabuluhang business intelligence.
Kung ang inyong engineering team ay sinusuri ang Chainway UR4, ang Nextwaves NR155 ay nag-aalok ng napaka-susunod na cloud-native na arkitektura. Ang mga legacy system ay likas na nagdudulot ng mataas na kapital na gastusin dahil sa vendor lock‑in at proprietary na ekosistema ng software.
Ganap na tinatanggal ng Nextwaves ang hadlang na ito sa pamamagitan ng pagbibigay ng standard na MQTT REST API direkta sa device. Ang inyong mga software developer ay maaaring i-integrate ang pagbasa ng mga tag direkta sa inyong custom na ERP o WMS backend sa loob ng ilang araw imbes na buwan, na ganap na iniiwasan ang paulit-ulit na bayad sa middleware licensing.

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.
