Pet trackers feem ntau siv GPS thiab BeiDou satellite positioning, ntxiv los ntawm Wi-Fi positioning, LBS base station positioning, and AGPS-pab positioning to achieve multi-level positioning indoor and outdoor. Tsis tas li ntawd, qee cov neeg taug qab tshiab siv tus kheej- teeb tsa kev siv thev naus laus zis, tsis muaj kev ywj pheej ntawm pej xeem cov xov tooj ntawm tes thiab lawv cov nqi kev pabcuam cuam tshuam. Ib qho chaw nres tsheb me me tuaj yeem npog thaj tsam li 2.5 mais thiab txhawb nqa kev taug qab ntawm ntau tus tsiaj. Lawv qhov chaw qhov tseeb tuaj yeem ncav cuag 2.5 meters, lossis hauv thaj tsam ntawm 5-10 meters.
Kev xa cov ntaub ntawv thaum ntxov tau tso siab rau 2G tes hauj lwm, tab sis tam sim no 4G LTE, Cat M1, thiab NB-IoT qis- zog dav- cheeb tsam network thev naus laus zis feem ntau siv rau kev xa cov ntaub ntawv, txhawb nqa tiag tiag- sijhawm taug qab. Raws li kev maj mam dhau los ntawm 2G tes hauj lwm, thev naus laus zis tau hloov mus rau NB-IoT ua ke nrog Wi-Fi thiab chaw nres tsheb hauv paus.
Cov khoom siv tseem ceeb, xws li qee yam NB-IoT chips, nta qis zog noj (0.9μA hauv PSM hom), me me (13 × 14mm), thiab kev sib koom ua ke siab, ua rau lawv haum rau cov neeg taug qab. Cov cuab yeej ua tiav kev tswj hwm kev siv hluav taws xob los ntawm kev ua haujlwm qis - lub zog chips thiab kev sib txuas lus daws teeb meem (xws li NB-IoT thiab Cat M1), nrog rau qee cov khoom siv ua tiav lub sijhawm tos ntawm ob peb lub hlis lossis ib xyoos. Kev lag luam tab tom ntsib kev siv thev naus laus zis sai sai, thiab qee cov khoom lag luam hauv kev txhim kho tab tom ua haujlwm txuas ntxiv rau tus neeg nrhiav lub roj teeb lub neej mus rau ib hlis.
