Ubuchwepheshe benethiwekhi yesikhangiso ye-IWAVE ye-single-frequency ad hoc ubuchwepheshe obuphambili kakhulu, obungacutshungulwa, nobusebenza kahle kakhulu be-Mobile Ad Hoc Networking (MANET) emhlabeni.
I-IWAVE's MANET Radio isebenzisa ifrikhwensi eyodwa nesiteshi esisodwa ukwenza ukudluliselwa kwemvamisa efanayo kanye nokudlulisela phakathi kweziteshi eziyisisekelo (usebenzisa imodi ye-TDMA), futhi idlulisela izikhathi eziningi ukuze ibone ukuthi ifrikhwensi eyodwa ingamukela futhi idlulise amasignali (i-single frequency duplex).
Izici zobuchwepheshe:
●Isiteshi esisodwa sidinga kuphela isixhumanisi esingenantambo sephoyinti elilodwa lefrikhwensi.
●Ikhuluma ngokuzenzakalelayo nenethiwekhi engenantambo (Adhoc), isivinini sokuxhumana esisheshayo.
●Inethiwekhi esheshayo ingasatshalaliswa ngokushesha esizeni ukuze kuqedelwe inethiwekhi engenazintambo ye-"four-hop" yeziteshi eziningi.
●Isekela i-SMS, ukuma kwe-radio mutual positioning (GPS/Beidou), futhi ingaxhunywa ku-PGIS.
Okulandelayo imibuzo yobuchwepheshe nezimpendulo abasebenzisi abakhathazeke ngazo:
●Uma uhlelo lomsakazo lwe-MANET lusebenza, imisakazo ephathwa ngesandla ithumela izimpawu zezwi nedatha, futhi lezi zimpawu zitholwa futhi zihlungwe ngabaphindaphinda abaningi, futhi ekugcineni amasignali anekhwalithi engcono kakhulu akhethiwe ukuze adluliselwe phambili.Isistimu ikwenza kanjani ukuhlolwa kwesignali?
Impendulo: Ukuhlolwa kwesignali kusekelwe emandleni esignali namaphutha amancane.Uma isignali inamandla futhi iyancipha amaphutha amancane, ikhwalithi engcono kakhulu.
●Ungabhekana kanjani nokugxambukela kwesiteshi?
Impendulo: Vumelanisa futhi uhlole amasignali
●Uma wenza ukuhlolwa kwesignali, ingabe umthombo wesithenjwa ozinzile uyanikezwa?Uma kunjalo, ungaqinisekisa kanjani ukuthi umthombo wereferensi ozinzile awunankinga?
Impendulo: Awukho umthombo oyisithenjwa ozinzile.Ukukhethwa kwesignali kusekelwe kumandla esignali nezimo zephutha elincane, bese kuhlungwa ngama-algorithms.
●Ezindaweni ezihambisanayo, ungaqinisekisa kanjani ikhwalithi yezingcingo zezwi?Ungaqinisekisa kanjani ukuzinza kokuxhumana?
Impendulo: Le nkinga ifana nokukhetha kwesignali.Endaweni egqagqene, isistimu ye-comms ebalulekile izokhetha amasignali ekhwalithi enhle yokuxhumana ngokusekelwe kumandla esignali nezimo zephutha elincane.
●Uma kunamaqembu amabili u-A no-B esiteshini esisodwa sefrikhwensi, futhi amaqembu A no-B aqala izingcingo eziya emalungwini eqembu ngesikhathi esisodwa, ingabe kuzoba nezibizo zesignali?Uma kunjalo, yimuphi umgomo osetshenziselwa ukwehlukana?Ingabe izingcingo kuwo womabili amaqembu zingaqhubeka ngokujwayelekile?
Impendulo: Ngeke kubangele isignali i-aliasing.Amaqembu ahlukene asebenzisa izinombolo zezingcingo zeqembu ezihlukene ukuze azihlukanise, futhi izinombolo zeqembu ezihlukene ngeke zixhumane.
●Yiliphi inani eliphezulu lomsakazo wehendisethi elingaphathwa yishaneli eyodwa yefrikhwensi?
Impendulo: Cishe awukho umkhawulo wobuningi.Izinkulungwane zamarediyo e-handset ayatholakala.Ekuxhumaneni kwenethiwekhi yangasese, umsakazo ophathwa ngesandla awudli izinsiza zesiteshi uma lungekho ucingo, ngakho-ke kungakhathaliseki ukuthi mingaki imisakazo ephathwa ngesandla, ingaphatha.
●Ungabala kanjani indawo ye-GPS esiteshini esiphathwayo?Ingabe ukuma kwephoyinti elilodwa noma ukuma okuhlukile?Ithembele kuphi?Ingabe ukunemba kuqinisekisiwe?
Impendulo: Imisakazo ye-IWAVE MANET yamaqhinga yakhelwe ngaphakathi kwe-gps/Beidou chip.Ithola ngokuqondile ulwazi lwayo lokuma kwe-longitude ne-latitude ngesathelayithi bese ibuyisela emuva ngesignali yegagasi ye-ultrashort.Iphutha lokunemba lingaphansi kwamamitha ayi-10-20.
●Inkundla yokuthumela isebenza njengenkampani yangaphandle yokuqapha izingcingo eqenjini lokuxhumana.Uma amashaneli aphathwa ifrikhwensi eyodwa esegcwele wonke, ingabe isiteshi sizovinjwa uma umuntu wesithathu efaka ucingo eqenjini lokuxhumana?
Impendulo: Uma iplatifomu yokuthumela ihlola izingcingo nje, ezingeke zisebenzise izinsiza zesiteshi ngaphandle kokuthi kuqaliswe ucingo.
●Ingabe kukhona okubalulekile kumakholi weqembu le-simulcast yemvamisa efanayo?
Impendulo: Umsebenzi obalulekile wekholi yeqembu ungathuthukiswa ngesoftware eyenziwe ngokwezifiso.
●Lapho iqembu lezokuxhumana eliphakeme liphazamisa ngenkani, ingabe iqembu lokuxhumana elinesiginali enamandla lizobekwa kuqala?
Impendulo: Ukuphazamiseka kusho ukuthi umsakazo ophethe ibhendi encane enegunya eliphezulu ungaphazamisa ukushaya bese uvula ucingo ukuze uvumele amanye ama-handset radio aphendule inkulumo yomsakazo wegunya eliphezulu.Lokhu akuhlangene namandla esignali yeqembu lokuxhumana.
● Zinqunywa kanjani izinto eziza kuqala?
Impendulo: Ngokufaka izinombolo, izinga eliphezulu lisebenzisa inombolo eyodwa, kanti izinga eliphansi lisebenzisa enye inombolo.
●Ingabe ukuxhumana phakathi kweziteshi eziyisisekelo kubalwa njengokuthatha isiteshi?
Impendulo: Cha. Isiteshi sizosetshenziswa kuphela uma kunocingo.
● Isiteshi esisodwa sesisekelo singadlulisela amasignali kusukela emaqenjini okuxhumana afika kwayisithupha ngesikhathi esisodwa.Uma kusetshenziswa iziteshi eziyisi-6 ngesikhathi esisodwa, ingabe kuzoba nokuminyana kweziteshi lapho iqembu lezokuxhumana elisezingeni eliphezulu liphazamisa ngenkani?
Impendulo: Ifrikhwensi eyodwa isekela izingcingo zeqembu lezokuxhumana eziyisi-6 ngesikhathi esisodwa, okuyindlela eqondile esesiza ngaphandle kokudlulisa ngesiteshi esiyisisekelo.Ukuminyana kwesiteshi kwenzeka lapho kusetshenziswa iziteshi eziyisithupha ngesikhathi esisodwa.Noma iyiphi isistimu egcwele izoba nokuvinjwa.
●Kunethiwekhi ye-simulcast yemvamisa efanayo, isiteshi esiyisisekelo sincike kumthombo wewashi ukuze usebenze ngokuhambisanayo.Uma umthombo wokuvumelanisa ulahlekile futhi isikhathi sibekwe kabusha isikhathi, ingabe kukhona ukuchezuka kwesikhathi?Kuyini ukuchezuka?
Impendulo: Iziteshi eziyisisekelo zenethiwekhi ye-co-channel simulcast ngokuvamile zivumelaniswa ngokusekelwe kumasathelayithi.Ekutakuleni izimo eziphuthumayo nasekusetshenzisweni kwansuku zonke, ngokuyisisekelo asikho isimo lapho umthombo wokuvumelanisa wesathelayithi ulahleka, ngaphandle uma kulahleka isathelayithi.
●Sithini isikhathi sokusungulwa ku-ms socingo lweqembu kunethiwekhi yokusakaza ye-simulcast efanayo?Ingakanani ukubambezeleka okukhulu ku-ms?
Impendulo: Zombili zingama-300ms
