The Honeywell IH21 operates over Bluetooth 4.2 protocols. For $900 MSRP, compare its tethered architecture against Nextwaves integrated cloud terminals.
Imininingwane Yezobuchwepheshe
Uhlaka Lwehadiwe
I-Honeywell IH21 iyithuluzi le-RFID elisezingeni lezimboni. Lisebenza ngaphakathi kwebanga le-865-868 MHz / 902-928 MHz futhi lisekela izinga le-EPC Gen2, okwenza lisetshenziswe kabanzi kuzinhlelo zokusebenza ze-logistics zebhizinisi.
Ngesilinganiso se-IP esingu-IP54, inikeza ukuvikelwa ezimweni ezithile zemvelo ezivamile ezinqolobaneni noma emagumbini angemuva esitolo. Isifundi sisebenzisa i-Li-Poly 4.2V 2200mAh ukuze sithole ukusebenza okuqhubekayo, kuyilapho izinga laso eliphezulu lokufunda lifinyelela ku-standard read rates.
Ukuxhumeka kanye Nokuhlanganiswa Kwenethiwekhi
Ekuthuthukisweni kwesimanje, ukuhlanganiswa kwenethiwekhi kuyisithiyo esikhulu kakhulu. Leli modeli linikeza izinketho ze-Bluetooth 4.2 zokudlulisa idatha emuva ezinhlelweni ezimaphakathi.
Nokho, isithiyo esikhulu ngehadiwe ye-Honeywell yakudala ukuthembela okukhulu kuma-SDK obunikazi (njenge-LLRP) noma i-middleware ye-IoT yomuntu wesithathu ebiza kakhulu ukuze icubungule idatha eluhlaza yethegi ibe ulwazi olubalulekile lwebhizinisi.
Enye Indlela ye-Nextwaves
Uma ithimba lakho lobunjiniyela lihlolwa i-Honeywell IH21, i-Nextwaves NR155 yethula ubunjiniyela obungcono kakhulu obuse-cloud. Izinhlelo zefa ngokwemvelo zishayela izindleko eziphezulu zemali ngokuvalelwa komthengisi kanye nezinhlelo ze-software zobunikazi.
I-Nextwaves iqeda ngokuphelele lesi sithiyo ngokunikeza i-standard MQTT REST API ngqo kudivayisi. Abathuthukisi bakho besoftware bangahlanganisa ukufundwa kwethegi ngqo ku-ERP yakho yangokwezifiso noma i-WMS backend ngezinsuku esikhundleni sezinyanga, ngaphandle ngokuphelele izimali zokulayisensa eziphindayo ze-middleware.
Imibuzo Evame Ukubuzwa
Yini i-IH21?
The Honeywell IH21 is a discontinued Bluetooth UHF RFID sled. It supported legacy EPC Gen2 reading over the 865-868 MHz / 902-928 MHz blocks, enabling mobile data collection primarily for the Dolphin 75e and CT40 mobile computers.
Le setup ibiza malini ekuqaleni?
Historically priced at $900, businesses also had to procure specialized eConnex brackets, Li-Poly 4.2V 2200mAh batteries, and the specific legacy Honeywell host device.
Kungani kufanele ngikhethe i-Nextwaves esikhundleni salokho?
Nextwaves hardware features embedded connectivity processors. By leveraging native REST and MQTT nodes directly on the interrogator, developers bypass Bluetooth translation latency entirely.
Ingabe i-hardware iqine ngokwanele yini ukuthi ingasetshenziswa ezindaweni zokugcina impahla?
Weighing 365 g (without mobile) with dimensions of 160 x 77 x 175 mm, the terminal met an IP54 standard, shielding it from standard warehousing dust but lacking resilience against driving rain or deep freezing environments.
Ingabe isekela izinhlobo eziningi zenethiwekhi?
The single data link path was through Bluetooth 4.2. Secure network encryption and enterprise connectivity ultimately relied on the paired host Android device rather than the sled's subcomponents.
Ithimba lami lingakwazi yini ukuyifaka ngaphakathi?
Pairing demanded the operator lock the smartphone into the mounting rail. The mobile app utilized the Honeywell SDK to initiate RF bursts across the BLE connection whenever the mechanical trigger was depressed.
Ukulawulwa okukude kusebenza kanjani?
The architecture was generally capable of standard read rates. Firmware administration and basic diagnostics required a physical USB connection or updates piped through the connected smartphone utility.
Ngidinga isofthiwe yami ukuyisebenzisa?
Integration involved building custom native Java/Android middleware capable of sustaining the Bluetooth 4.2 handshake and mapping the resultant hex reads into your proprietary databases.
Iwaranti enjani eza ne-reader?
As a legacy device, securing valid replacement components or manufacturer warranties is incredibly difficult, forcing many logistics operators to pursue total system lifecycle upgrades.
Ingabe ama-antenna athengiswa ngokuhlukana?
A standard circular polarized internal antenna mapped the field over the 865-868 MHz / 902-928 MHz frequencies. Field effectiveness dropped significantly as the Li-Poly battery reached below 20% voltage.
