MANET (Inethiwekhi ye-Ad Hoc yeselula)
I-MANET luhlobo olutsha lwenethiwekhi ye-broadband ye-wireless mesh esekelwe kwindlela yothungelwano lwe-ad hoc. Njengothungelwano lwe-ad hoc yeselula, i-MANNET izimele kwiziseko zophuhliso zenethiwekhi ezikhoyo kwaye ixhasa nayiphi na i-topology yenethiwekhi.
Ngokungafaniyo nothungelwano olungenacingo lwemveli olunezitishi ezikumbindi (izitishi ezisisiseko), i-MANET yinethiwekhi yonxibelelwano olunabileyo. Iyilwe ngengqikelelo entsha yothungelwano olunatyisiweyo olunatyisiweyo, yinkqubo yonxibelelwano esasazwe ngaphandle kwamacingo equka ukuhanjiswa kweehop ezininzi, umzila oguquguqukayo, ukomelela olomeleleyo, kunye nokukaleka okugqwesileyo. Uthungelwano luxhasa nayiphi na i-topology kwaye, ngeprothokholi yomzila ozinikeleyo, yenza ukuba unxibelelwano lwedatha kunye nonxibelelwano lweenkonzo ezahlukeneyo phakathi kweendawo zenethiwekhi ngokugqithiswa kwee-wireless multi-hop ngokusebenzisa iindawo ezikufutshane.
I-MANET inikezela ngeenzuzo ezifana neendleko eziphantsi zokuthunyelwa kunye nokugcinwa, ukugubungela ngokubanzi, isantya esiphezulu, inethiwekhi eqinile, ukulungelelaniswa okunamandla, kunye nokudibanisa ukuzazi kunye nokuziphilisa. Ingasebenza njengenethiwekhi ezimeleyo ye-ad hoc ezimeleyo kunye nokuhambelana okusebenzayo kunye nolwandiso kwiinkqubo ezikhoyo zothungelwano ezingafaniyo.
I-MANET inokusetyenziswa ngokubanzi kuthungelwano lonxibelelwano olungxamisekileyo, uthungelwano lolwazi lweshishini, uthungelwano lwe-broadband yengingqi, iinethiwekhi zokubeka iliso ezingenazingcingo, uthungelwano lolawulo olusebenzisanayo kunye nothungelwano olukrelekrele.
MIMO(Iimveliso ezininzi zokuPhuma kaninzi)
I-MIMO (i-Multiple Input Multiple Output) iteknoloji isebenzisa ii-eriyali ezininzi zokuhambisa kunye nokufumana i-eriyali kwi-transmitter kunye ne-receiver, ngokulandelanayo, ivumela imiqondiso ukuba idluliselwe kwaye ifumaneke ngee-eriyali, idala iziteshi ezininzi phakathi komthumeli kunye nommkeli wokuhanjiswa kwedatha.
Undoqo wetekhnoloji ye-MIMO kukusetyenziswa kwee-eriyali ezininzi ukubonelela ngenzuzo yokwahluka (ukwahluka kwendawo) kunye nenzuzo yokuphindaphinda (i-spatial multiplexing). Eyangaphambili iqinisekisa ukuthembeka kothumelo lwenkqubo, ngelixa le yokugqibela inyusa izinga losulelo lwenkqubo.
Ukwahluka kwendawo ngokusisiseko kubonelela ngeekopi ezininzi, ezizimeleyo ezizimeleyo zeesimboli zolwazi kumamkeli, ukunciphisa amathuba okufiphala kweempawu ezinzulu, ngaloo ndlela kuphuculwe ukusebenza kwenkqubo kunye nokuphucula ukuthembeka kunye nokomelela kothumelo. Kwinkqubo ye-MIMO, ukufiphala kuzimele kwiperi nganye yokuhambisa nokufumana ii-eriyali. Ke ngoko, itshaneli ye-MIMO inokujongwa njengeendlela ezininzi ezihambelanayo zendawo. Ukuphindaphinda kwendawo kubandakanya ukusasazwa kwedatha eyahlukileyo kwezi ndlela zininzi zizimeleyo, ezihambelanayo, ukwandisa kakhulu umthamo wetshaneli. Kwithiyori, umthamo wetshaneli wenkqubo ye-MIMO unokunyuka ngokuhambelana nenani lokuhambisa kunye nokufumana ii-eriyali.
Itekhnoloji ye-MIMO ibonelela ngeyantlukwano yendawo kunye nokuphindaphinda indawo, kodwa kukho urhwebo phakathi kwezi zimbini. Ngokusebenzisa ngokufanelekileyo zombini iindlela zokwahluka kunye neendlela zokuphindaphinda kwinkqubo ye-MIMO, ukuzuzwa kwenkqubo kunokwandiswa, kuzuzwe ukuthembeka kunye neenzuzo ezisebenzayo ngelixa kusetyenziswa ngokupheleleyo izixhobo ezikhoyo ze-spectrum. Oku kuza ngexabiso lokunyuka kobunzima bokuqhuba kuzo zombini ii-transmitter kunye nomamkeli.
Itekhnoloji ye-MIMO kunye neteknoloji ye-MANET zimbini zetekhnoloji ezingundoqo kwiinkqubo zangoku zonxibelelwano ezingenazingcingo kwaye zamkelwa ziinkqubo ezininzi zonxibelelwano ezingenazingcingo.
Malunga IWAVE
Ngaphezu kweminyaka elishumi, i-IWAVE inikezelwe kuphando oluzimeleyo kunye nophuhliso lwetekhnoloji yonxibelelwano olungenazingcingo. Ngokuqhubeka nokutyhala imida yeenkcukacha zobugcisa ezikhoyo kunye nokuphindaphinda isakhelo setekhnoloji ye-MANET, inkampani ngoku inepotfoliyo ebanzi ye-WANET waveforms enamalungelo apheleleyo azimeleyo epropathi yomgangatho ophezulu wokuqonda, esebenza kwiinkalo ezahlukeneyo.
Ngokubonelela abathengi ngetekhnoloji kunye neemveliso zonxibelelwano olusebenzayo, olukhuselekileyo, kunye nokuzimela, sixhobisa abasebenzisi ngelizwi elikhawulezayo, elisebenzayo, neligudileyo elipheleleyo, idatha, ividiyo, kunye nomyalelo obonakalayo kunye nokukwazi ukuthumela, ukusebenzisa amandla okwenziwa ngobukrelekrele baseTshayina. Oku kuvumela abasebenzisi ukuba bafezekise ngokwenene "uqhagamshelo nanini na, naphi na, kwaye xa beluncedo" kwiimeko ezahlukeneyo.
