Nezoqhagamshelwano Radio-relay

Iinkqubo Radio-relay unxibelelwano (PPC) namhlanje yindlela ebalulekileyo lothungelwano iinkcukacha zothutho: kubo ngendlela enye okanye enye ixhomekeke umsebenzi ebalulekileyo uninzi elililo sabemi behlabathi. Le iteknoloji kubandakanya ukudluliselwa kolwazi ngokusebenzisa uthungelwano kwizikhululo irileyi. umgca radio ezisentlabathini ihanjiswa kwi isentimitha kunye decimeter uluhlu, xa ezitsho engamakhulu aliqela MHz ukuya eziliqela amashumi GHz.

nezoqhagamshelwano Radio-relay banamalungelo zilandelayo:

- amathuba ngokuthumela umqondiso njengoko narrowband kunye broadband;

- multi-kwitshaneli ngokupheleleyo-kabini (-kabini ezimbini, ukubonelela nokufumana kunye yokusasaza) unxulumano phakathi izikhokhelo;

- okukwazi phantse ngokupheleleyo wokuphazamiseka yaye okwakhiwa "ngasemva" zoshishino;

- ngaphantsi kakhulu xa kuthelekiswa unxibelelwano Esetyenzisiweyo, ngelixa uthungelwano lombutho;

- izixhobo eriyali emxinwa-engile, enqamla ukwanda kummandla lilonke kwimvelaphi electromagnetic.

Nangona kunjalo, ukusetyenziswa PPC yi olungenayo ethile kunye, ngenxa yemfuneko ukunika:

- eriyali isikhundla esiphezulu kunye nejiyometri "ukubonakala" ngqo phakathi transceiver ezikufutshane;

- ukwandisa inani lezikhululo eziphakathi kulingana ukwandisa umgama transmission umqondiso.

Ukongeza, ezi iinkqubo nezixhobo zonxibelelwano kakhulu enkulu, kunye nokwakhiwa kothungelwano kwiindawo ezikude kunzima kunikezo nofakelo yayo.

Konke oku kungentla ludlala indima ebalulekileyo ukuba imigca unxibelelwano relay radio naphi na apho kunokwenzeka, kufakwe yi fibre-optic (ezinesigqubuthelo seplastiki). Igalelo ukufuduka kwabo ukukhula rhoqo traffic nomthwalo uthungelwano zothutho. Ifayibha-optic iindawo wemetropolitan iyakuba ngokuqinisekileyo ngokuthe babe indawo ephezulu, kodwa isikali Russian kunye neempawu nophuhliso imigca zothutho kusengaphambili ukuzithemba eziya kusetyenziswa ngokubanzi ezayo eminyaka inkqubo yonxibelelwano microwave. inani elikhulu kwiindawo apho ulwakhiwo kunye nokusasazwa fibre optic bamane ukuhlawula kwizikhewu ezikule yelizwe lethu.

Yaye ukusetyenziswa ifayibha enombala njengoko uthungelwano ezinkulu akayi izakulahleka imfuneko yogcino, kuba imigca intambo zixhomekeke breakage kwaye, ngenxa yoko, abaliqela kwemitshini elide. Kwaye kukho unxibelelwano relay radio elilalela okhuphisana inkqubo abanazo.

Ngaphezu koko, uyakwazi ukuthetha nje kuphela ukulondolozwa yabo, kodwa ke uphuhliso olungaphezulu: mathemba oku kwenza ukuba ubomi bethu engenayo TV yedijithali. Entlanganweni osasazo kamabonakude yedijithali na isisombululo PPC efanelekileyo, idini kakhulu eyamkelekileyo umgangatho namhlanje umnxeba, iindleko kunye nesantya deployment. Oku libizwa kakhulu ikwimo yasasazwa njalo elinye. Kwaye ngokunxulumene lula sokungenisa / izixhobo zobhaliso kufunyanwe imvume, wayixela benomdla e-PPC kumashishini kunye nemibutho ukuba udale uthungelwano corporate.
