1.GPS Positioning
I-Global Positioning System (GPS) yinkqubo yokuma yerediyo echanekileyo ephezulu esekwe kwiisathelayithi zomhlaba ezenziweyo. Inokubonelela ngendawo yendawo echanekileyo, isantya semoto kunye nolwazi oluchanekileyo lwexesha. I-GPS itsale abasebenzisi abaninzi ngokuchaneka kwayo okuphezulu, yonke imozulu, ukugubungela ihlabathi, ukulunga kunye nokuguquguquka.
I-GPS sisizukulwana esitsha sokuhamba ngesathelayithi kunye nenkqubo yokubeka indawo eye yaphuhliswa yi-United States ukusukela ngeminyaka yoo-1970 yaza yagqitywa ngokupheleleyo ngo-1994.
Umgaqo wokuSebenza we-GPS: Umgaqo osisiseko wenkqubo yokukhangela ye-GPS kukulinganisa umgama phakathi kwendawo eyaziwayo yesathelayithi kunye ne-receiver yomsebenzisi, kwaye emva koko udibanise idatha yeesathelayithi ezininzi ukwazi indawo ethile yomamkeli.
2.LBS Isikhundla
Inkonzo esekwe kwindawo (LBS) isetyenziswa ngokubanzi kubasebenzisi befowuni ephathwayo. Yinkonzo esekwe kwindawo efumana abasebenzisi beterminal ephathwayo ngonxibelelwano, uthungelwano lonxibelelwano lukanomathotholo lwabaqhubi beselula (njengenethiwekhi ye-GSM, inethiwekhi yeCDMA) okanye iindlela zokubeka ngaphandle (ezifana neGPS). Ngenkxaso ye-GIS (iNkqubo yoLwazi lweJografi) iqonga, libonelela abasebenzisi ngenkonzo eyongezelelweyo yexabiso leenkonzo ezihambelanayo.
Umgaqo-siseko wokuSebenza we-LBS: Ifowuni ephathwayo ibhalisa i-SIM khadi, kwaye ngendawo eyaziwayo yendawo yesikhululo kunye nokwahlukana komqondiso phakathi kwemodyuli yeBluetooth kunye nezikhululo ezahlukeneyo zesiseko, indawo yefowuni ephathekayo inokufumaneka nge-algorithm ethile.
3.Wi-Fi Real-Time Positioning
I-Wi-Fi yokwenyani yexesha letekhnoloji isebenzisa inethiwekhi ekhoyo engenazingcingo, kunye nemodyuli ye-Wi-Fi kunye nezixhobo ezihambelanayo ze-terminal ezifana ne-Wi-Fi ifowuni ephathwayo, iPDA, ilaptop, njl., idityaniswe ne-algorithm yokumisa ehambelanayo, ukumisela indawo yabantu abafanelekileyo kunye nezinto.
I-Wi-Fi ye-Real-Time Positioning Principle Working Principe: I-teknoloji ye-Wi-Fi isetyenziselwa ubukhulu becala kwindawo yangaphakathi. Ngokufanayo ne-LBS, imodyuli nganye engenazingcingo kunye ne-AP inedilesi ye-MAC ekhethekileyo yehlabathi. Xa i-Wi-Fi ivuliwe, isixhobo sinokuskena kwaye siqokelele imiqondiso ye-AP ejikelezileyo, nokuba i-encrypted okanye ayikho, ingaba ixhunyiwe okanye ayikho, xa amandla omqondiso anganelanga ukuba aboniswe kuluhlu olungenazintambo, inokufumana idilesi ye-MAC esasazwa yi-AP. Emva koko isixhobo sithumela idatha ye-AP kwiseva yendawo, kwaye iseva ibuyisela indawo yendawo ye-AP nganye, idibanisa amandla esignali, ibala indawo yendawo yesixhobo, kwaye iyibuyisele kwisixhobo somsebenzisi.
4.iBeacon Positioning
I-iBeacon ngumsebenzi omtsha oxhotyiswe nge-OS (iOS7) yezixhobo eziphathwayo ezikhutshwe yi-Apple ngoSeptemba ka-2013.
I-iBeacon Positioning Umgaqo wokuSebenza: Ngokusebenzisa iteknoloji yeBluetooth ephantsi kwamandla, isikhululo sesiseko se-iBeacon singenza indawo yesignali, kwaye xa ifowuni ingena kwindawo, isicelo esihambelanayo siya kubangela ukuba umsebenzisi adibanise kwinethiwekhi yesignali. Ngeenzwa ezincinci ezingenazintambo ezinokufakwa kuyo nayiphi na into kunye neBluetooth Low Energy technology, abasebenzisi banokusebenzisa i-iPhone ukuhambisa idatha.
Ngokomzekelo, ukuba uhamba kwivenkile kwindawo enkulu yokuthenga nge-iPhone 5s (eqhuba i-iOS 7 kunye nokuxhasa i-iBeacon), oko kuthetha ukuba ungene kwindawo yesignali ye-iBeacon yevenkile. Isikhululo sesiseko se-iBeacon sinokudlulisela ulwazi olwahlukeneyo kwi-iPhone yakho, ezinje ngeekhuphoni okanye ulwazi lokukhangela kwivenkile, kwaye unike neengcebiso zemveliso eyenzelwe wena xa usiya kwizinto zokubala ezithile. Ngamanye amazwi, ngaphakathi kwendawo yolwazi yesikhululo sesiseko se-iBeacon, abasebenzisi banokufumana ulwazi lwendawo encinci kunye nezaziso ngee-smartphones zabo.
