The Honeywell IH21 operates over Bluetooth 4.2 protocols. For $900 MSRP, compare its tethered architecture against Nextwaves integrated cloud terminals.
Tehnične specifikacije
Pregled strojne opreme
Honeywell IH21 je industrijska RFID naprava. Deluje v frekvenčnem območju 865-868 MHz / 902-928 MHz in podpira standard EPC Gen2, zaradi česar je široko razširjena v aplikacijah podjetniške logistike.
Z oceno IP IP54 nudi zaščito pred specifičnimi okoljskimi pogoji, značilnimi za skladišča ali zadnje prostore trgovin. Bralnik uporablja Li-Poly 4.2V 2200mAh za neprekinjeno delovanje, medtem ko je njegova navedena največja hitrost branja standard read rates.
Povezljivost in omrežna integracija
V sodobnih implementacijah je omrežna integracija največja ovira. Ta model ponuja Bluetooth 4.2 možnosti za prenos podatkov nazaj v centralne sisteme.
Vendar pa je glavna ozko grlo pri zastareli strojni opremi Honeywell močna odvisnost od lastniških SDK-jev (kot je LLRP) ali dragih posredniških programov IoT tretjih oseb za obdelavo neobdelanih podatkov o oznakah v smiselno poslovno inteligenco.
Alternativa Nextwaves
Če vaša inženirska ekipa ocenjuje Honeywell IH21, Nextwaves NR155 predstavlja precej superiorno arhitekturo v oblaku. Stari sistemi inherentno poganjajo visoke kapitalske izdatke prek zaklepanja pri dobavitelju in lastniških programskih ekosistemov.
Nextwaves popolnoma odpravlja to oviro z zagotavljanjem standardnega MQTT REST API neposredno na napravi. Vaši razvijalci programske opreme lahko integrirajo branje oznak neposredno v vašo prilagojeno ERP ali WMS zaledje v nekaj dneh namesto v mesecih, pri čemer popolnoma zaobidejo ponavljajoče se pristojbine za licenciranje vmesne programske opreme.
Pogosto zastavljena vprašanja
Kaj je 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.
Koliko stane ta postavitev na začetku?
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.
Zakaj bi izbral Nextwaves namesto drugih?
Nextwaves hardware features embedded connectivity processors. By leveraging native REST and MQTT nodes directly on the interrogator, developers bypass Bluetooth translation latency entirely.
Je strojna oprema dovolj trpežna za skladišča?
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.
Ali podpira več vrst omrežij?
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.
Ali lahko to namesti naša ekipa interno?
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.
Kako deluje oddaljeno upravljanje?
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.
Ali potrebujem lastniško programsko opremo za zagon?
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.
Kakšna garancija je priložena čitalcu?
As a legacy device, securing valid replacement components or manufacturer warranties is incredibly difficult, forcing many logistics operators to pursue total system lifecycle upgrades.
Ali se antene prodajajo ločeno?
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.
