Xa uvula usetyenziso lwemephu oluthandayo kwaye ubuze, "ithini indawo yam yangoku?", ichaphaza elibhlowu livela kwisikrini phantse ngoko nangoko. Unokucinga ukuba lo ngumsebenzi wesathelayithi zeGPS ezijikeleza uMhlaba. Ngelixa i-GPS idlala indima, iqhawe lokwenyani lokuhamba edolophini ngokwenene kukulandela umkhondo we-Wi-Fi.
Imida yeGPS
IGlobal Positioning System (GPS) ichane ngendlela emangalisayo, kodwa inesiphene esinye esikhulu: ifuna umgca othe ngqo wokujonga esibhakabhakeni. Ukuba ungaphakathi kudederhu lweevenkile, kwisikhululo sikaloliwe esingaphantsi komhlaba, okanye ujikelezwe zizakhiwo eziphakamileyo, iimpawu zesathelayithi ezibuthathaka azinakufikelela kwifowuni yakho. Ukuba ifowuni yakho ixhomekeke kuphela kwi-GPS ukufumana indawo yakho indawo endikuyo ngoku, ubuya kuhlala ulahlekelwa ngumqondiso wakho ngaphakathi.
Isebenza njani iWi-Fi Positioning System (WPS).
Ukusombulula ingxaki yangaphakathi, iinkampani zobugcisa zenze iWi-Fi Positioning System. Nokuba awuqhagamshelwanga kwinethiwekhi ye-Wi-Fi, ifowuni yakho ihlala ijonga amagama (ii-SSID) kunye needilesi ze-MAC zeerutha ezikufutshane.
Iinkampani ezifana noGoogle kunye neApple zichithe iminyaka zenza imephu yendawo phantse yonke i-Wi-Fi router emhlabeni (kaninzi ngokuqhuba iimoto zekhamera ezantsi esitratweni). Xa ubuza ifowuni yakho "iyiphi indawo yam yangoku", ijonge i-3 okanye i-4 i-Wi-Fi routers enokuyibona ngeenxa zonke kuwe, ihlola iindawo zabo ezaziwayo kwi-database, kwaye i-triangulate indawo yakho ngqo.
Ukusebenza Kunye
Ii-smartphones zanamhlanje zisebenzisa "Imowudi yokuChaneka okuphezulu" edibanisa zombini itekhnoloji ngaphandle komthungo. Isebenzisa i-Wi-Fi ukufumana isilungiso esikhawulezayo sokuqala kwaye igcine umkhondo wakho ngaphakathi, kwaye isebenzisa i-GPS ukukulandelela ngokuchanekileyo xa uqhuba uhola wendlela ocacileyo.
