Astaanteeda ugu weyn waa in la kala saaro unugga farsamaynta soo noqnoqda raadiyaha iyo qaybta farsamaynta saldhigga saldhigga saldhigga weyn oo lagu xidho iyada oo loo marayo fiber indhaha. Fikradda udub-dhexaadka ah ee qaab dhismeedka saldhiga la qaybiyey waa in la kala saaro unugga farsamaynta saldhiga saldhiga macro (BBU) iyo unugga farsamaynta soo noqnoqda raadiyaha (RRU). Labaduba waxay ku xidhan yihiin fiber optic. Inta lagu jiro hawlgalinta shabakada, qaybta farsamaynta baseband, shabakada xudunta ah, iyo qalabka xakamaynta shabakada wireless waxay ku urursan yihiin qolka kombuyuutarka waxayna ku xiran yihiin qaybta fogaanta raadiyaha ee la geeyay goobta la qorsheeyay iyada oo loo marayo fiber-ka indhaha si loo dhamaystiro daboolida shabakada, sidaas darteed hoos u dhigista kharashka dhismaha iyo dayactirka. iyo hagaajinta waxtarka.

Saldhigga saldhiga ee la qaybiyay ayaa u kala qaybiya agabka saldhiga caadiga ah ee saldhiga laba qaybood oo shaqaynaaya iyadoo loo eegayo hawlahooda. Saldhigga saldhigga, kantaroolka ugu weyn, gudbinta, saacadda, iyo hawlaha kale ee saldhigga saldhigga ayaa lagu dhex daray cutubka loo yaqaan cutubka saldhigga BBU (Base Band Unit). Cutubku cabbirkiisu waa yar yahay, meesha lagu rakibayna waa mid aad u dabacsan; inta jeer ee raadiyaha dhexe sida transceiver iyo amplifier awood waxa lagu dhex darayaa mid kale oo loo yaqaan moduleka soo noqnoqda raadiyaha fog, iyo unugga soo noqnoqda raadiyaha ee RRU (Remote Radio Unit) ayaa lagu rakibay dhamaadka anteenada. Unugga soo noqnoqoshada raadiyaha iyo unugga saldhigga waxay ku xiran yihiin fiilooyinka indhaha si ay u sameeyaan xal saldhigeed cusub oo qaybsan.

SDRBaseStareen

SDR (Software Definition Radio) waa "software qeexan raadiyaha", kaas oo ah tignoolajiyada isgaarsiinta baahinta wireless-ka, si sax ah, waa habka naqshadeynta ama fikradda naqshadeynta. Gaar ahaan, SDR waxa ay tilmaamaysaa hab-maamuuska isgaadhsiinta bilaa-waayirka ah ee ku salaysan qeexida softiweerka halkii ay ka ahaan lahayd hirgelinta qalabka loo qoondeeyay. Hadda waxa jira saddex qaab-dhismeedka qalabka SDR ee caadiga ah: Qaab-dhismeedka SDR-ku-salaysan ee GPP, Qaab-dhismeedka Barnaamij-ku-salaysan ee Gate Array (FPGA) -dhismeedka SDR (Non-GPP), iyo qaab-dhismeedka SDR-ku-salaysan ee GPP + FPGA/SDP. Qaab dhismeedka SDR ee ku salaysan GPP waa sida soo socota.

Saldhigga Saldhigga SDR waa nidaam saldhigeed oo loo qaabeeyey lana sameeyay iyadoo lagu salaynayo fikradda SDR. Muuqaalkeeda ugu weyn ayaa ah in unuggeeda soo noqnoqda raadiyaha la barnaamijayn karo oo dib loo qeexi karo, oo ay xaqiijin karaan qoondaynta caqliga leh ee spectrum iyo taageerada hababka shabakado badan, taas oo ah, waxaa loo isticmaali karaa isla qalabka madal. Tiknoolajiyada si loo hirgeliyo moodooyinka shabakadaha kala duwan, sida ku cad shaxanka hoose, shabakada GSM+LTE waxaa lagu hirgeliyay qalab isku mid ah.

RP celiyaha

RP celiyaha: Ku celiyaha RP wuxuu ka kooban yahay qaybo ama qaybo sida anteenooyinka,RF duplexers, cod-weyneyaal dhawaq yar, mixers, ESCatenuators, filtarrada, amplifiers koronto, iwm., oo ay ku jiraan xiriirinta kor-u-qaadista iyo kuwa hoose.

Mabda'a aasaasiga ah ee shaqadeeda waa: in la isticmaalo anteenada hore (anteenada deeqaha) si loo helo calaamadda hoose ee saldhigga saldhigga ee ku celisiyaha, ku kordhiso calaamadda waxtarka leh iyada oo loo marayo cod-weyneeye-yaryar, xakamaynta signalka dhawaaqa ee calaamadda, iyo hagaajinta saamiga signal-ilaa-sanqa (S/N). ; ka dib waxaa hoos loo rogaa oo loo rogaa signalka soo noqnoqda dhexdhexaadka ah, waxaa lagu shaandheeyaa shaandheyn, lagu kordhiyo inta jeer ee dhexdhexaadka ah, ka dibna kor loo beddelayo inta jeer ee raadiyaha, lagu kordhiyo cod-weyneeye, waxaana lagu sii gudbiyaa saldhigga mobaylka anteenada gadaal (dib u gudbinta). anteeno); Isla mar ahaantaana, anteenada gadaal ayaa la isticmaalayaa signalka kor u kaca ee ka imanaya isteeshinka mobaylka waxaa la helaa oo lagu farsameeyaa isku xirka kor u qaadida ee wadada ka soo horjeeda: taas oo ah, waxay dhex martaa cod-weyneeye-hooseeya, hoos-beddele, filter, dhexdhexaad ah. cod-weyneeye, kor u beddele, iyo cod-weyneeye ka hor inta aan loo gudbin saldhigga saldhigga. Tani waxay gaadhaysaa xidhiidhka laba-geesoodka ah ee u dhexeeya saldhiga saldhiga iyo saldhiga mobaylada.

Dib-u-celinta RP waa sheyga gudbinta signal-la'aanta. Tilmaamaha ugu muhiimsan ee lagu cabbiro tayada soo noqnoqda waxaa ka mid ah heerka sirdoonka (sida la socodka fog, iwm.), IP3 hoose (in ka yar -36dBm oggolaansho la'aan), factor hoose ee qaylada (NF), isku hallaynta guud ee mashiinka, adeegyada farsamada wanaagsan. iwm.

RP repeater waa qalab isku xidha khadadka shabakada waxaana inta badan loo isticmaalaa isu gudbinta laba jiho ee calaamadaha jireed ee u dhexeeya labada nood ee shabakada.

Ku celi

Ku celisku waa aaladda isku xidhka shabakada ugu fudud. Waxay inta badan dhamaystirtaa hawlaha lakabka jirka. Waxay mas'uul ka tahay gudbinta macluumaadka xoogaa xoogaa ah ee lakabka jireed ee labada nood iyo buuxinta nuqulka signalka, hagaajinta, iyo xoojinta shaqada si loo kordhiyo dhererka shabakadda.

Luminta awgeed, awoodda signalka lagu kala qaado khadka ayaa si tartiib tartiib ah u yaraan doonta. Marka hoosudhacu gaadho heer gaar ah, waxay keeni doontaa khalkhal calaamadeed, sidaas darteed waxay keenaysaa khaladaad soo dhawayneed. Ku celceliyaasha waxaa loo qaabeeyey si ay u xaliyaan dhibaatadan. Waxay dhamaystiraysaa isku xidhka xadhkaha jireed, waxay kordhisaa calaamada la dhimay, waxayna u dhigtaa la mid ah xogta asalka ah.

Marka la barbardhigo saldhigyada saldhigga, waxay leedahay faa'iidooyinka qaab-dhismeedka fudud, maalgelin yar, iyo rakibid habboon. Waxaa si weyn loogu isticmaali karaa meelaha indhoolayaasha ah iyo meelaha daciifka ah ee ay adag tahay in la daboolo, sida xarumaha ganacsiga, hoteelada, garoomada diyaaradaha, dekedaha, saldhigyada, garoomada ciyaaraha, hoolalka madadaalada, tareenada dhulka hoostiisa mara, tunnel-yada, iwm. Waxaa loo isticmaali karaa meelo kala duwan sida. jidadka waaweyn iyo jasiiradaha si loo hagaajiyo tayada isgaarsiinta oo loo xalliyo dhibaatooyinka sida wicitaanada la tuuray.

Halabuurka ku celceliyaasha isgaadhsiinta mobaylada way kala duwan yihiin iyadoo ku xidhan nooca.
