The Honeywell IH21 operates over Bluetooth 4.2 protocols. For $900 MSRP, compare its tethered architecture against Nextwaves integrated cloud terminals.
Vipimo vya Ufundi
Muhtasari wa Vifaa
Honeywell IH21 ni kifaa cha RFID cha kiwango cha viwanda. Kifaa hiki hufanya kazi ndani ya masafa ya 865-868 MHz / 902-928 MHz na kinaunga mkono kiwango cha EPC Gen2, na kuifanya itumike sana katika matumizi ya vifaa vya biashara.
Kwa ukadiriaji wa IP wa IP54, inatoa ulinzi dhidi ya hali maalum za mazingira za kawaida katika ghala au vyumba vya nyuma vya rejareja. Kisomaji hutumia Li-Poly 4.2V 2200mAh kwa utendaji endelevu, wakati kiwango chake cha juu cha usomaji kinasema kuwa ni standard read rates.
Ushirikiano wa Muunganisho na Mtandao
Katika matumizi ya kisasa, ushirikiano wa mtandao ndio kikwazo kikubwa zaidi. Mfumo huu unatoa chaguo za Bluetooth 4.2 kwa kuhamisha data kurudi kwenye mifumo mikuu.
Hata hivyo, tatizo kubwa na vifaa vya Honeywell 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.
Mbadala wa Nextwaves
Ikiwa timu yako ya uhandisi inatathmini Honeywell IH21, 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.
Maswali Yanayoulizwa Mara kwa Mara
IH21 ni nini?
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.
Usanidi huu unagharimu kiasi gani mwanzoni?
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.
Kwa nini nichague Nextwaves badala yake?
Nextwaves hardware features embedded connectivity processors. By leveraging native REST and MQTT nodes directly on the interrogator, developers bypass Bluetooth translation latency entirely.
Je, vifaa vina uimara wa kutosha kwa maghala?
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.
Je, inasaidia aina nyingi za mtandao?
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.
Je, timu yangu inaweza kusakinisha hii ndani?
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.
Usimamizi wa mbali unafanyaje kazi?
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.
Je, ninahitaji programu ya umiliki ili kuiendesha?
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.
Udhamini gani unakuja na kisoma?
As a legacy device, securing valid replacement components or manufacturer warranties is incredibly difficult, forcing many logistics operators to pursue total system lifecycle upgrades.
Je, antena zinauzwa kando?
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.
