Ubuchwepheshe bokuxhumana kwanamuhla ngaphandle kobunzima bungahlela indawo yokusebenza egcwele endaweni egcwele ezweni lezwe.
Indawo yeselula yeselula yeselula "Beeline"
I-Intanethi ekotishini seliyatholakala kubo bonke
Ngosizo lobuchwepheshe beselula, ungadlulisela umsindo kuphela, kodwa futhi nezithombe ezithombeni
Izindaba zase-East.
Ikhulu le-XXI alikubizi ngephutha iminyaka yobudala bolwazi. Impilo yanamuhla kunzima ukucabanga ngaphandle kocingo, lo mngane othembekile womuntu webhizinisi. Akumangazi ukuthi impikiswano yocingo lokuqina kangaka lukhathaze kakhulu abanikazi bezindlu zezwe.
Ucingo lwezakhamizi ezikanye nathi eziningi akulona ukunethezeka futhi kungezona ngisho nezindlela zokuxhumana, kodwa into ebalulekile yomsebenzi webhizinisi. Uma kunokuxhumana ngocingo, bakwazile ukufana nendawo yokusebenza egcwele ekhaya noma ezweni. Lesi sici sikhanga kakhulu abanikazi be-rustic cottage. Ngemuva kwakho konke, impilo ethule ngokwemvelo, kude nesiphithiphithi sedolobha, ama-traffic jams kanye nomoya onobuthi onobuthi, ubukeka epharadesi ngempela.
Namuhla, uhlele "impilo eyiPharadesi enjalo ilula, ubuchwepheshe besimanje buvumela. Izakhamuzi zedolobha zizodinga isigamu sehora ukuze idilizwe lenkontileka ne-opharetha ephathekayo. Kepha ukuhlala unomphela esifundazweni "sezithulu" kubeka izidingo eziningi ezengeziwe zokuxhumana ngocingo. Isibonelo, kuyadingeka ukuthi inqubo iqinisekise ukuqiniseka, ngaphandle kokuphazamiseka, ukuthola isibonakaliso. Ngaphezu kwalokho, lapho uxhuma kwi-Intanethi, isiteshi sokuxhumana kumele sibe ne-bandwidth ethile eqinisekisa ukushintshana kwedatha okugcwele. Okokugcina, kuyinto efiselekayo ukuthi izindleko zokukhokha kwezinsizakalo zokuxhumana zazincane. Vele, imfuneko yokugcina ifanele bonke ababhalisile, kepha ikakhulukazi kulabo abasebenzisa kakhulu izingcingo ngokwabo kanye nezinsizakalo ezingeziwe ezinikezwe ngaphakathi kohlaka lwayo.
Kuzoba yini iziphakamiso?
Manje, kuzo zonke izindlela zokuxhumana ngocingo, ezimbili zasatshalaliswa kabanzi. Lesi nge-telephony enentambo, noma, njengoba ibizwa nangokuthi, ukuxhumana ngocingo okuhleliwe, nokudluliswa kwedatha ngesiteshi somsakazo. Sizokutshela okuningi ngezinzuzo zabo nobubi babo.Ucingo olunentambo - Indlela elula elula futhi ethembekile. Umsebenzisi oxhunywe kwi-PBX, njengomthetho, uthola isibonakaliso ngeleveli yekhwalithi eyamukelekayo, ezimele ezimweni zeMeteo. Iziteshi zokuxhumana ezinentambo zibonakala nge-bandwidth ephezulu, ikakhulukazi lapho usebenzisa izintambo zesimanje ze-fiber optic. Lokhu kukuvumela ukuthi usebenzise umugqa hhayi ukuxhumana ngezwi kuphela, kepha futhi udlulise olunye ulwazi, lufinyelele esithombeni sevidiyo. Imigqa ye-fiber optic ithembisa kakhulu kusuka endaweni yokubuka ijubane lokudlulisa idatha kanye nokungavikeleki komsindo. Ngakho-ke, akukhona ngengozi ukuthi yimigqa enjalo esetshenziswa ezindaweni ezinkulu zasendlini eduzane naseMoscow. Ubuchwepheshe obukhona (ngokwesibonelo, i-XDSL) ikuvumela ukuthi uhlele ukufinyelela kwe-Intanethi okusheshayo kanye nenombolo yocingo ejwayelekile. Kulokhu, umugqa uhlala ukhululekile.
Ukuxhumana okunentambo kwe-CEDDOws kufaka phakathi izindleko eziphakeme kakhulu zokufakwa kanye nokubekwa kwentambo. Isibonelo, esifundeni saseMoscow ukufeza umugqa we-fiber-optic ubiza izinkulungwane ezimbalwa zamaRandi nge-1km. Inani elikhulu lababhalisile esigodini sezwe lingafakwa kuthelevishini ngale ndlela cishe ama- $ 500-1000. Ezindaweni eziningi ezikude ezikude, izinsizakalo zokuxhumana ngocingo okunentambo futhi namuhla zihlale zingafinyeleleki. Ngesifunda esifanayo saseMoscow ngaphezulu kwezinkulungwane ezimbili. I-ethandwa emaphandleni isuswe ngokuphelele. Yebo, nokuthi kukuphi, ikhwalithi yakhe kwesinye isikhathi ayihambisani nanoma yikuphi ukugxekwa ngenxa yemishini eyedlule efakwe ku-Analog PBX, kanye nemigqa yokuxhumana ngokudluliselwa kwesiginali ngaphezulu kocingo lwezindlu ezimbili.
Ukuhanjiswa kwedatha ngesiteshi somsakazo kungenziwa ngezindlela eziningi. Dlulisela phambili, konke kuyinto yokuxhumana eyaziwa ngeselula. Lapha, isibonakaliso sokuhumusha sedivayisi sitholakala ukuze kuqinisekiswe ukwamukela kwalo endaweni ethile ("endaweni esetshenzisiwe"), ngaphandle kokudala ukuphazamiseka komsakazo (inethiwekhi yomhumushi ohlelweni ifana namaseli e-Hexagonal, ukusuka lapho elinye igama lalolu hlobo lokuxhumana livela). Ukuxhumana kweselula kuyakhanga amakhasimende amaningi ngokuyinhloko kusuka endaweni yezomnotho yokubuka, ngenxa yezindleko eziphansi zemishini (umakhalekhukhwini) kanye nezimali ezinhle zokubhalisa. Namuhla, umakhalekhukhwini ungathengwa ngo- $ 50-100, futhi izindleko zokukhokha amasu we-Economical Tariff aqhathaniswa namanani entengo yezinsizakalo zocingo ezivukile. Ngasikhathi sinye, izinsizakalo zabasebenza ngamaselula ziyaqhubeka nokushibhile - ngenxa enkulu ngenxa yokuncintisana kwemakethe eqinile (indawo yokuhlala kusuka ezinkonzweni zokuxhumana okunentambo).
Kodwa-ke, ukuxhumana kweselula kanye nokubi. Okokuqala, inani elithile lolwazi ngalunye lwemininingwane edluliselwe kusetshenziswa ifoni ephathekayo namanje kusale kaningana kunezindleko zokudluliswa kwedatha ngokuxhunyaniswa kwedatha. Ngaphezu kwalokho, kuvela ubunzima ngokudluliselwa kwenani elikhulu lolwazi olungadingeka ukuze lusebenze kahle kwi-Intanethi. Ngakho-ke, ngohlaka lwe-Digital Mobile Communication Standard eRussia, izinga lokushintshana kwedatha phakathi kombhalisile kanye ne-node yezokuxhumana kuphela i-9.6-14.4kbit / S, ngakho-ke, i-GSM ayisetshenziselwa ukufinyelela kwi-Intanethi.
Ukuze wenze lokhu, kunezobuchwepheshe bokudlulisa idatha kwanamuhla. Isibonelo, indinganiso ye-GPRS esetshenziselwa ukuthumela i-imeyili nokubuka izingosi ze-Intanethi; I-Edge (Advanced GPRS), avumeli nje ulwazi lombhalo kuphela, kodwa namavidiyo nezithombe zevidiyo.
Ikusasa elikude kakhulu, opharetha basemakhaya bahlela ukuguqulwa kwi-UMTS yesithathu ngezizukulwane ezijwayelekile (uhlelo lwe-Universal Mobile Telecommunication System), oluhlinzeka ngezinga lokudlulisa idatha kusuka ku-384kbit / s kuya ku-2 MBPS. Ukukhiqizwa kabusha kwevidiyo yokusakaza, okwenza umhlangano wevidiyo osebenzayo nezinsizakalo ezifanayo. Kucatshangwa ukuthi leli Zinga elithile lizokwethulwa eRussia.
Ngaphezu kwalokho, inkinga iba yikhwalithi ephansi yokuxhumana nebanga elikhulu elivela esiteshini somhumushi (indawo yamaselula). Okwamaselula, ibanga elibucayi lingu-8-10km. Izinga lokuxhumana lincike kakhulu ebukhoneni (ubuntu) bengqalasizinda yokudlulisa kwimithombo yezingcingo, imithombo engaba khona yokuphazamiseka, ukuxhumana kubi kakhulu.
Ukuxhumana Radio usebenzisa i-antenna edlulisela Kusetshenziswa lapho ukubeka ikhebula kubiza kakhulu noma kungenakwenzeka ubuchwepheshe. Izinzuzo zalobu buchwepheshe bokufinyelela kwe-wireless Broadband yizindleko ezincane zokufakwa (kusuka kumakhulu amaningana amadola), ijubane lokufakwa kwemishini (ngokwesilinganiso amaviki amabili ukuhlela isiteshi sokuxhumana), ukugcwala okuphezulu kwesiteshi sokuxhumana kanye nekhono ukuhlinzeka ukwamukelwa kwekhwalithi ephezulu yesiginali ebanga elikhulu (kuze kube ngamakhilomitha ambalwa). Ama-kednostats afaka iqiniso lokuthi imishini yokubhalisela iklayenti kufanele ibe nokubonakala okuqondile okuhlobene nesiteshi (ukudlulisa) esiteshini. Ngaphezu kwalokho, ikhwalithi yokuxhumana ingawohloka ngezimo ezingezinhle zemete (esivunguvungwini).
Enye indlela yokuxhumana ngocingo lwedivayisi I-Satellite Communications (MSS). Ukubhoboza okuphindile kwe-Signal lapha kusetshenziswa ama-satellite okufakelwa emhlabeni atholakala kuma-orbits we-geoStationary. Bajikeleza kanye neplanethi yethu, ngakho-ke bahlala bevela njalo ukuba ngaphezulu kwephuzu elifanayo lomphezulu walo. I-Satellite Communications ihlinzeka ngekhwalithi ephezulu yesiginali noma kuphi emgqeni: Ku-taiga, olwandle, ugwadule ... kuphela izindawo ezifanayo ezihlala zingasebenzi. Isibhedlela, lolu hlobo lokuxhumana lubiza kakhulu: umzuzu wengxoxo "kubiza i-satellite" $ 3, futhi amanani entengo yamafoni we-satellite eshintshashintsha ama-dollar ayizinkulungwane eziningana. Ngakho-ke, ukuxhumana okunjalo kusetshenziswa kuphela ezimweni lapho ezinye izindlela zingenakwenzeka.
