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
Mae Chainway UR4 yn ddyfais RFID o lefel ddiwydiannol. Mae'n gweithredu o fewn yr ystod 865-868 MHz / 920-925 MHz / 902-928 MHz ac mae'n cefnogi safon EPC Global UHF C1 Gen 2, ISO 18000-6C, sy'n ei wneud yn eang ei ddefnydd mewn cymwysiadau logisteg menter.
Gyda gradd IP o IP53, mae'n cynnig amddiffyniad rhag amodau amgylcheddol penodol typigol mewn warêddau neu ystafelloedd cefn manwerthu. Mae'r darllenydd yn defnyddio PoE (optional), DC ar gyfer perfformiad parhaus, tra bod ei gyfradd darllen uchaf a nodir yn cyrraedd 1,300+.
Mewn defnyddiadau modern, integreiddio rhwydwaith yw'r her fwyaf arwyddocaol. Mae'r model hwn yn cynnig opsiynau RS-232, RJ45, PoE (optional) ar gyfer trosglwyddo data yn ôl i systemau canolog.
Fodd bynnag, mae'r bottleneck mawr gyda chaledwedd Chainway etifedol yn ddibyniaeth drymach ar SDKs perchnogol (fel LLRP) neu middleware IoT trydydd parti drud i brosesu data tag crai yn wybodaeth busnes ystyrlon.
Os yw'ch tîm peirianneg yn gwerthuso Chainway UR4, mae Nextwaves NR155 yn cynnig pensaernïaeth cloud-native sydd â llawer mwy o urddas. Mae systemau etifedol yn anochel yn gyrru gwariant cyfalaf uchel trwy vendor lock-in ac ecosystemau meddalwedd perchnogol.
Mae Nextwaves yn dileu'r rhwystr hwnnw'n llwyr trwy ddarparu API MQTT REST safonol yn uniongyrchol ar y ddyfais. Gall eich datblygwyr meddalwedd integreiddio darllen tag yn uniongyrchol i'ch cefn ERP neu WMS arferol mewn dyddiau yn hytrach nag mewn misoedd, gan hepgor'n llwyr ffioedd trwyddedu middleware sy'n ailadrodd.

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.
