Kev sib txuas lus nta raws tu qauv

NB-IoT & LTE Cat.1 Version

Cov qauv no txhawb nqa ob qho tib si NB-IoT thiab LTE Cat.1 kev xaiv kev sib txuas lus ntawm tes (xaiv tau thaum teeb tsa raws li kev muaj nyob hauv network). Nws yog qhov zoo tagnrho rau kev xa tawm hauv nroog,

muab kev pabcuam dav dav, muaj zog nkag mus, thiab kev sib raug zoo nrog cov neeg nqa khoom loj.

Feature Kev piav qhia

Zaus Bands B1 / B3 / B5 / B8 / B20 / B28

Fais fab kis 23dBm ib± 2 dB ib

Hom Network NB-IoT thiab LTE Cat.1 (xav rov qab xaiv tau)

Remote Firmware Upgrade DFOTA (Firmware Over The Air) txhawb nqa

Huab kev koom ua ke UDP muaj

Cov Ntaub Ntawv Txhua Hnub Khov Khaws 24 lub hlis ntawm kev nyeem txhua hnub

Lub Hlis Cov Ntaub Ntawv Khov Khaws 20 xyoo ntawm cov ntsiab lus txhua hli

Tamper Detection Ua rau tom qab 10+ pulses thaum tshem tawm

Magnetic Attack Alarm 2-thib ob lub voj voog nrhiav kom pom, keeb kwm thiab nyob tus chij

Infrared Maintenance Rau kev teeb tsa, kev nyeem ntawv, thiab kev kuaj mob

Siv Case:

Zoo tagnrho rau high-frequency cov ntaub ntawv uploads, kev soj ntsuam kev lag luam, thiab cov cheeb tsam uas muaj neeg coob uas xav tau kev cia siab ntawm cellular.

LoRaWAN Version

Qhov no version yog optimized rau ntev-ntau thiab tsawg-power deployments. Tau tshaj cov pej xeem lossis ntiag tug LoRaWAN tes hauj lwm, nws txhawb nqa topologies hloov tau thiab kev pab cuam tob hauv

nyob deb nroog los yog ib nrab nroog.

LoRa Chav Chav Kawm A (default), Chav KawmB,Chav Kawm C xaiv tau

Koom nrog Hom OTAA / AB

Kev sib kis Mus txog 10 km (nyob deb nroog) /5 km (hauv nroog)

Cloud Protocol LoRaWAN txheem uplinks

Txhim kho firmware Xaiv los ntawm multicast

Tamper & Sib nqus tswb Ib yam li NB version

Infrared Maintenance Txhawb nqa

Siv Case:

Qhov zoo tshaj plaws rau cov zej zog nyob deb nroog, cov chaw ua si dej / roj av, lossis AMI cov haujlwm siv LoRaWAN gateways.
