Maxaan samayn karnaa marka dib-u-kicinta is-xakamaynta?

Waa maxay dib-u-kicinta calaamada moobaylka?

Is-xakamaynta macneheedu waxa weeye in calaamada uu ku cel-celiyuhu xoojiyay uu galo dhammaadka helidda ee cod-weyneysiinta labaad, taas oo keenaysa in cod-weyneyuhu uu shaqeeyo xaalad buuxda.Dib-u-kicinta dib-u-kicinta waxay ka muuqataa kaliya ku celiyaha wireless-ka.Sababtoo ah soo noqnoqda fiber optical-ka ayaa si toos ah ugu lammaansan calaamadda saldhigga saldhigga, sidaas darteed soo-celiyaha fiber-ka ma dhalin doono is-xanaajin, ka soo qaad dib-u-celiyaha fiber optic-ga wuxuu leeyahay calaamad.Laakin haddii aadan wici karin taleefoon ama tayada wacitaanka oo liidata ee ku celcelinta fiber optical.Xaaladdaas, waxaa lagu talinayaa in la hubiyo kor u kaca iyo hoos-u-dhigga attenuation iyo hardware repeater.

Waa maxay is kicin

Tusaale ahaan, isbeddellada heerkulku waxay keenaan isbeddelka faa'iidada cod-weyneeye, go'doomin, iyo cabbirrada saldhigga saldhigga;ka dib, waxay keeni doontaa korodhka gelinta soo noqnoqda.Marka aad saxdo soo-celiyaha, fadlan si xad dhaaf ah ha u raacin cod-weyneysiinta oo si weyn u hagaaji faa'iidada.Waa inaad meel uga tagtaa.Kuwa soo noqnoqda ee leh diiwaanada khaladka ah, way adagtahay in la ogaado is-casiyeynta kanaalka rogaal celiyaha ah.Sababtoo ah kanaalka hore ee soo-celiyaha ayaa had iyo jeer leh gelinta signalka saldhigga saldhigga, haddii ku celiyaha uu iskiis u faraxsan yahay, cod-weyneeye hore ayaa laga yaabaa in la kordhiyo.Qaar ka mid ah soo-celiyeyaasha waxay ogaadaan in cod-weyneyuhu uu culeys badan yahay saddex jeer.Isla markiiba way damin doonaan soo-celinta oo waxay siin doonaan rikoodh cad oo guul-darrida.Way fududahay in la helo.Si kastaba ha ahaatee, calaamada gelinta ee cod-weyneeye kanaalka gadaasha aad ayuu u kala duwan yahay.Gudbiyaha talefanka gacanta mar walba kuma jiro xaalada gudbinta, masaafada mar walba isku mid maaha.

Xaaladaha qaarkood, waxay keeni doontaa in cod-weyneeye kanaalka rogaal-celiska uu is-qiimo.Cod-weyneyuhu wuxuu ku soo noqdaa sidii caadiga ahayd sababtoo ah luminta degdega ah ee wax gelintaIs-xakamaynta cod-weyneeye kanaalka gadaasha ma aha oo kaliya dhowr ilbiriqsi oo gaaban oo aan joogto ahayn.Mararka qaarkood iskuma xamaasadsato hal mar dhowr saacadood, taas oo aad u adag in la saxo qaladka.

Haddii soo-celiyaha la rakibo, talefanka gacanta ayaa caadi ahaan ka jawaabi kara talefanka maxaliga ah haddii talefanka gacanta uu kula xidhiidho talefanka deegaanka.Weli, taleefoonka maxalliga ah waa go'an yahay marka laga jawaabayo taleefanka gacanta, tayada dhawaaquna waa mid hooseeya.Waxaa laga yaabaa inay sababto is-xakamaynta cod-weyneeye kanaalka gadaasha ee soo-celiyaha.

Marka celiyaha si khaldan loo rakibo, go'doominta anteenada transceiver kuma filna.Faa'iidada soo-celinta oo dhan aad bay muhiim u tahay.Digniinta wax soo saarka ayaa dib loogu celin doonaa gelinta ka dib daahitaan, taasoo keeneysa qallooc daran oo ah calaamadda soo-celinta soo noqnoqda iyo is-qaad-qaad.Xaddiga soo noqnoqda ee is-xakamaynta calaamaduhu way dhici doontaa.Ka dib is-xakamaynta, tayada mowjadda calaamaduhu way ka sii daraan, taas oo si dhab ah u saameynaysa tayada wicitaanka waxayna keentaa hoos u dhaca wicitaanka.

Waxaa jira laba siyaabood oo looga gudbi karo ifafaalaha is-xakamaynta.Mid waa in la kordhiyo go'doominta anteenada ku-deeqaha iyo anteenada dib-u-gudbinta, midda kalena waa in la yareeyo faa'iidada soo-celinta.Marka caymiska soo noqnoqda loo baahan yahay inuu yaraado, faa'iidada waa la yarayn karaa.Marka soo-celiyaha loo baahan yahay inuu daboolo aag ballaaran, go'doominta waa in la kordhiyaa.

- Kordhi masaafada jiifka iyo toosan ee anteenooyinka

-Ku dar caqabadaha, sida rakibidda shabaqyada gaashaanka, iwm

- Kordhi toosinta anteenada ku-deeqaha, sida isticmaalka anteenada parabolic

- Dooro anteenada dib u gudbinta oo leh jiho ka xoog badan, sida anteenooyinka xagasha jihada

- Hagaaji xagasha iyo jihada deeq bixiyaha iyo anteenada dib u gudbinta si ay u kala fogaadaan intii suurtagal ah.
