Inethiwekhi kawonke-wonke iWalkie{0}}uHlalutyo lokuSebenza kweTalkie: Ukuphumelela ngokuphindiweyo kuQhagamshelwano oluSebenzayo kunye nokuthembeka

Tyhila-ukuya-uThetha ngeSelula (i-PoC), indlela ephuculweyo ye-walkie yesintu{2}}intetho, iphakamisa uthungelwano lonxibelelwano oluphathwayo ukwenza unxibelelwano olukhawulezileyo, olunqamlezayo{3}}lommandla, lubonise iingenelo ezizodwa kulungiselelo, ukhuseleko, impendulo kaxakeka, kunye neminye imimandla. Ukusebenza kwayo akugcini nje ukugqiba amava omsebenzisi kodwa kuchaphazela ngokuthe ngqo ukuthembeka konxibelelwano kwiimeko ezibalulekileyo. Okulandelayo kuhlalutya ezona mpawu ziphambili zokwenziwa komsebenzi womnatha woluntu{6}}iintetho ezisuka kwiimbono ezininzi.

I. UNxibelelwano loNxibelelwano: "Uqhagamshelwano olungenamda" olophula iMida yoMgama

Iintetho zesiqhelo ze-walkie-zixhomekeke kumaza kanomathotholo, kunye noluhlu lonxibelelwano olusebenzayo luthintelwa kwiikhilomitha ezimbalwa ukuya kumashumi eekhilomitha (kuxhomekeke kumbane kunye neemeko zokusingqongileyo). Inethiwekhi yoluntu{2}}iintetho, nangona kunjalo, qhagamshela kwiinethiwekhi zabathwali nge-4G/5G okanye i-Wi{5}}Fi, ngokwethiyori ivumela unxibelelwano olungenamthungo kwilizwe lonke nakwihlabathi jikelele. Umzekelo, kwiindawo zasezidolophini ezinezikhululo ezixineneyo, amandla omqondiso anele ukuxhasa iminxeba ezinzileyo kwiindawo zokupaka eziphantsi komhlaba nangaphakathi{7}}kwizakhiwo eziphakamileyo. Kwiindawo ezikude, okoko kukho inethiwekhi (efana nomqondiso we-4G), ii-talkies zenethiwekhi yoluntu{10}}zinokugcina uqhagamshelwano. Eminye{12}}imifuziselo ephezulu isekwaxhasa ezimbini-iSIM yokulinda kabini okanye ukutshintshela kwinethiwekhi okuzenzekelayo. Xa isignali yenethiwekhi esisiseko iyancipha, inkqubo itshintshela ngokukhawuleza kwinethiwekhi yokugcina, inciphisa ngakumbi umngcipheko wokuphazamiseka konxibelelwano.

II. Isantya sokuphendula: "Zero Latency" UPhumo ukusuka kwi-Keystroke ukuya kwiLizwi

Elona xabiso le-walkie{0}}talkies lilele "kumyalezo wangoko nangoko." Ukubambezeleka kwenethiwekhi yoluntu{2}}iintetho ezichaphazela ngqo amava omsebenzisi. Izixhobo zakwangoko ezisekwe kwi-2G/3G uthungelwano zihlala zifumana i-1{11}}3 ulibaziseko lwesibini ngenxa yokungonelanga komthamo womnatha womnatha. Nangona kunjalo, iichipsets zangoku ze-4G LTE Cat.1/Cat.4, zidityaniswe nemigaqo yeVoIP ephuculweyo, ziye zacutha isiphelo{12}}ukuya{14}}ukugqiba latency ukuya ku-0.5{16}}1.2 imizuzwana, ukusondela "cofa uhambe" amava emveli ye-analog walkie{18}}intetho ephantsi ye-talkies{15} ye-network ehamba phambili{15} i-latency (i-theory latency phantsi kwe-100 milliseconds) ukuhlangabezana neemfuno zeemeko ezichanekileyo ezifana nolawulo olude lwemizi mveliso. Kufanelekile ukuqaphela ukuba i-latency yokwenyani ikwachatshazelwa kukuxinana kwenethiwekhi. Kwiindawo ezixineneyo (ezifana neekonsathi), ukuba izitishi ezisisiseko zigcwele kakhulu, ukubambezeleka kunganyuka okwethutyana. Nangona kunjalo, ezininzi izixhobo ziqinisekisa ukuhanjiswa kwedatha yezwi ngokufanelekileyo nge-QoS (uMgangatho weNkonzo) yokucwangcisa phambili.

III. Umgangatho welizwi kunye nokucaciswa: Ukulingana kokuLahlwa koMphazamiso kunye neTekhnoloji yokuKhowuda

Umgangatho weaudio yenethiwekhi kawonke-wonke i-walkie{0}}iintetho zithintelwe kuzo zombini imo yenethiwekhi kunye ne-algorithm yekhowudi. I-analog walkie yesintu-intetho, ngexa ingenakho ukuphazamiseka koxinzelelo, iba sesichengeni sokuphazamiseka kombane, okukhokelela kwingxolo. Inethiwekhi kawonkewonke i-walkie{4}}iintetho zisebenzisa ikhowudi yedijithali (efana ne-AMR-ilizwi le-WB ebanzi kunye ne-Opus adaptive coding) ukulungelelanisa ukucaca kunye nokuchaswa kokuphazamiseka ngaphakathi kwe-bandwidth elinganiselwe. Izixhobo ezingundoqo zixhasa i-8kHz kunye ne-16kHz imilinganiselo yesampulu{9}}i-kHz ikhowudi yebhendi ebanzi inokuphinda ivelise iinkcukacha ezityebileyo{10}}eziphindaphindayo (ezifana nesandi esivakalayo kunye nezandi ezingasemva), ziyenze ilungele iimeko ezifuna ugqithiso lolwazi oluchanekileyo (njengokuqinisekiswa komyalelo wokhuseleko). Ngaphaya koko, ukuqukwa kwengxolo{12}}yokurhoxisa imakrofoni kunye ne-echo yokurhoxiswa kwe-algorithm ihluza ngokufanelekileyo uphazamiseko olufana nengxolo yomoya kunye nezixhobo ingxolo yombane, ukuqinisekisa ukuba omabini amaqela angayiva ngokucacileyo imiyalezo ephambili nakwiziza zokwakha ezinengxolo okanye kubume bezithuthi.

IV. Ubomi bebhetri kunye nokuthembeka: Iimpawu ezibalulekileyo zexesha elide{1} lokuSebenza kweXesha

Ubomi bebhetri yenethiwekhi kawonke-wonke i-walkie{0}}intetho ichaphazela ukukwazi kwabo ukusebenza ngokuqhubekayo. Abathengi abaqhelekileyo -izixhobo zebakala zikholisa ukuba nomthamo webhetri wama-2000-3000mAh, ukubonelela nge-8-iiyure ezili-12 zokusebenza okuqhubekayo kwintlawulo epheleleyo (ukusetyenziswa okuphakathi ukuya kokuphantsi{12}}kobunzulu). Iimodeli zobuchwephesha zisebenzisa iibhetri ezinkulu (4000 -} 6000mAh) okanye zibonisa uyilo olunokutshintshwa. Ulawulo lwamandla ngobukrelekrele (njengendlela yokulala kunye{15}}nebhetri ecofa kancinci) kwandisa ixesha lokusebenza, ezinye iimodeli zixhasa ngaphezulu kweeyure ezili-15 zokusetyenziswa kakhulu. Ngokuphathelele ukuthembeka, i-industrial{18}}yemigangatho yezindlu ze-intercom yenethiwekhi kawonkewonke zihlala zenziwe ngeplastiki yobunjineli bobunjineli obuphezulu okanye isinyithi, ukufikelela kwi-IP67 (uthuli kunye nokungangeni kwamanzi, okufanelekile ukuntywiliselwa kwexesha elifutshane) okanye i-IP68 (ukumelana nokuntywila nzulu) amanqaku. Ziphinde zivavanywe ukuhla (ngaphezu kweemitha ze-1.5) kwaye zivavanyelwe ukushisa okuphezulu kunye nokuphantsi (-20℃ukuya kwi-60 degree), ukuqinisekisa ukusebenza okuzinzile kwiindawo ezinzima (ezifana nemisebenzi yokuhlangula imvula kunye nokwakhiwa kwangaphandle).

V. Umsebenzi owandisiweyo: Ukusuka kuMnxeba oSisiseko ukuya kwiNtsebenziswano enoBukrelekrele

Ii-intercom zenethiwekhi zikawonke-wonke zanamhlanje zidlule ngaphaya konxibelelwano lwelizwi olulula, ukudibanisa iintlobo ngeentlobo zeempawu ezisebenzayo ukunyusa ukusebenza kakuhle. Ngokomzekelo, iimodyuli zokubeka i-GPS / i-Beidou zinokulayisha iindawo zesixhobo kwiiplatifti zokulawula ngexesha langempela, okwenza amaziko okuthumela ukuba ahlole ukuthunyelwa kweqela. Usasazo lwemultimedia luxhasa ukuthumela imifanekiso kunye neevidiyo ezimfutshane, zizenza zilungele{2}}ukuqokelelwa kobungqina besiza okanye ukunika ingxelo yobume besixhobo. Ezinye izixhobo zikwahambelana noqhagamshelo lweBluetooth (yee-headsets kunye ne-microphone eziphathwayo), uqinisekiso lwe-NFC (ulawulo lwemvume), kunye nelizwi le-AI{4}}ukuya{5}}kumbhalo, ukuguqula ngokuzenzekelayo imiyalelo yelizwi kwiirekhodi ezibhaliweyo ukuze kube lula ukulandeleka. Ezi mpawu zandisiweyo zibenza bakwazi ukuhlangabezana neemfuno ezisisiseko ze-intercom kuphela kodwa badibanise kwiinkqubo zolawulo lwedijithali, babe sisixhobo esibalulekileyo sobukrelekrele boshishino.

Isishwankathelo: Izibonelelo zokusebenza zenethiwekhi kawonke-wonke i-walkie{0}}iintetho zigxininiswe kwimilinganiselo emine engundoqo: i-coverage ebanzi, i-latency ephantsi, umgangatho oqinileyo we-audio, kunye nokuthembeka okuphezulu. Idityaniswe nezibonelelo zesiseko senethiwekhi ephathwayo, zijongana neendawo ezibuhlungu zeentetho zendabuko-, ezifana noluhlu olulinganiselweyo kunye nokusebenza okulinganiselweyo. Ngokwamkelwa ngokubanzi kothungelwano lwe-5G kunye nokuvela kobuchwepheshe be-chip, i-walkie yenethiwekhi yoluntu{5}}iintetho ziya kuqhubeka ziguqukela kwi-latency ephantsi, ukucaca okuphezulu, kunye nentsebenziswano ekrelekrele ngakumbi, ibonelela ngenkxaso yobugcisa eyomeleleyo kwiimfuno zonxibelelwano olukhawulezileyo lwamashishini ahlukeneyo.
