Modern kutaurirana maturusi uye migero kushumira isu kwete chete sezvo murevereri nokuda nokupfuuridzirwa mashoko. Vanokwanisa kupa uye vatsigire basa zvigadziriswe namano, vatariri vebasa vashandi kuti ari kure kushandisa zvakaoma rwokugadzira.

About maererano mhando kwave akati zvizhinji. Tinongofanira zvinyore. Saka, nokuti mashoko kuchinjwa , unogona kushandisa neteregirafu, runhare, redhiyo, gudzanzwi nhepfenyuro, terevhizheni, Satellite uye pafoni kukurukurirana, zvinogona itsva (3G, 4G, etc.), kombiyuta that no wired uye Wireless network. Muchiitiko chino, nemhaka kukura ruzivo mumunda kukurukurirana uye nokuchinja, unhu uye ikakuruma mwero iri kuwedzera. Rinokosha pakuita ichi kutamba Links. Pavari ichakurukurwa.

Types uye kupatsanura yokukurukurirana migero

Tisati tataura pamusoro mhando, zvine musoro kuziva musimboti "kutaurirana pakuparadzira" pfungwa. Rinoreva hurongwa zvinosanganisira svikiro umo Mashoko chiratidzo, uye pamusoro michina namano uye zvishandiso zvinopa uye kutsigira Mashoko somureza womumwe kakawanda pane imwe nokukurumidza.

Maererano kupatsanura kana typology, ratova kukurukurirana migero inogona kupatsanurwa sezvinotevera:

• By mhando conductive svikiro (waya kana redhiyo maitikiro).
• By Frequency chikuva (Zvakanaka hf, VHF, UHF, microwave bhendi, millimeter bhendi, michini).
• Maererano chiratidzo mhando (analoginen kana digitaalinen).

Vakawanda kunge vakanzwa mashoko akadai digitaalinen kukurukura migero kana Manyiminya makwara. Ndezvipi zvavo chinosiyanisa zvinhu kana makomborero?

Digital channel nekufambisa mashoko ari muchimiro binary code, inova rinoumbwa chete 0 uye 1. noruzivo ichi, zvaigoneka kuita shoma kurasikirwa kana uori data, mukusiyana kusvika analoginen nzira. Somuenzaniso, apo achitaura pafoni iri anowanzoshandiswa analoginen chiratidzo uchishandisa nhungamiro iri kuramba vari kuchinjwa magetsi oscillations. Nekuti analoginen hurongwa mashoko Exchange ndiko vaifurirwa kukanganiswa uye anogona yekudyidzana kuvhiringidza mashoko kana kuti kurasikirwa mashoko.

Optical Links zvakasiyana nemamwe acho, iro waya yakaitwa. Optical fibers akashandiswa gadzira dzavo, anobvumira kupa mukuru bandwidth, kana shoma kusarurama chiratidzo rutapudzo kunyange madaro marefu, kutapata kuti kukanganiswa. Mukuwedzera, faibha pakuburitswa mutengo iduku zvikuru uye kupenya zvayo uchitikurudzira miganhu. Maererano nemamwe mabhuku, uremu kwakajairika netambo kunogona 10 nguva kurema Manyiminya conductors yakafanana saizi. Optical hazvipo zvose digitaalinen sezvo nekufambisa mashoko chimiro ichi.

Hatigoni kutaura pamusoro Wireless gwara. Vamwe vavo tinoshandisa pasina kunyange kufunga nezvazvo. Muenzaniso uyu anogona kuva michini (Laser) mugero. Kunoita kuti dzitarisire TV kana zvimwe mudziyo pamwe kure, iro rinopa rinotungamirirwa danda wechiedza. For Wireless Links dzinosanganisira:

• Michini kana Laser.
• Microwave Feeds (kushandiswa kuongorora kana ld).
• Free redhiyo Network (mukana chiratidzo hutachiwana mune mapoka akawanda).
