Isgaarsiinta casriga ah - xiriir degdeg ah

suuqa isgaarsiinta waa mid ka mid ah goobaha ugu wanaagsan oo ugu dhaqsiyaha badan sii kordhaya ee shirkadaha isgaarsiinta ee. Currently, nidaamka isgaarsiinta waa waddada horumarka degdeg ah, guud ahaan, waxaa diiradda lagu galo nidaamka isgaarsiinta Ruush ah dunida ugu soo galay sida lamaane siman si ay u bixiyaan adeegyada caalamiga ah, long-distance, magaalada, xogta, internet, mobile, iwm ..

Waa maxay Isgaarsiinta ee

"Isgaarsiinta" Ereyga waxaa laga erayadan: Latin communico, taas oo macnaheedu yahay "foomka of isgaarsiinta," iyo gudodomiyaha Giriigga, oo macnihiisu yahay "simaha meel fog ka weyn."

Sidaas daraaddeed, waxaan oran karnaa in:

• Isgaarsiinta - a collection of qalabka iyo barnaamijyo ay u gudbiyaan macluumaad via channels cable iyo raadiyaha. qalab Tani macluumaadka diinta, ay kelmadaha, isbedbeddelka, Tani technology processing computer sare.
• Telecommunications qalab - set oo ah farsamo, software iyo hab ururka for gudbinta xogta fog. Sammeecado saarka adag-state waxaa loo isticmaalaa in la abuuro war laliska ee idacadda satellite.
• Isgaarsiinta - idman Service Center awood u gudbinta iyo la helo fariimaha. Khubaro isgaarsiinta - farsamo iyo injineerada. Waxay inta badan la codes, signalada, qaylada shaqeeyaan.
• Isgaarsiinta - waa is-dhaafsiga wixii macluumaad iyadoo la kaashanayo of computer ah. Macluumaadka waxaa lagu kala qaado iyada oo loo marayo khadaka warisgaarsiinta ee ama war isdhaafsi.
• Isgaarsiinta - waa hab of loo helo iyo ka shaqeynta macluumaadka la isticmaalayo elektaroonik ah, network, electromagnetic, macluumaadka iyo teknoolajiyada computer.

meelaha ididiilo tiknolojiyada isgaarsiinta waa in la tixgeliyaa:

1. Abuuritaanka qaab-dhismeedka cusub signal-code by isticmaalka farsamooyinka la xoojiyey ee calaamadaha khalkhalgelinta iyo farsamooyinka signal habaynteeda cusub si loo kordhiyo nidaamka bandwidth iyo gudbinta si ay u horumariyaan awooda.
2. Abuuritaanka qalabka antenna smart oo xoog ku fiicnaaday.
3. Abuurista hababka isgaarsiinta ee millimeter ah band ruxruxo la soo noqnoqoshada ah oo shaqo ku dhowaad 100 GHz.
4. Horumarinta ee hababka iyo teknoolajiyada ee qalabka isgaarsiinta, kaas oo hubinaya in ay qaab ciyaareed fiican oo ah shuruudaha guud, kharashka ugu yar, oo xuduudaheedu ugu badnaan, isku halaynta ugu badnaan, miisaanka yar iyo sifooyinka size.
5. Kordhinta heerka tababarka ardayda jihada of "Telecommunications", ballaarinta cilmi iyo horumarinta jihada.

A signal habaynteeda Technology habka

Waayo, tamarta fiicnayn nidaamka isticmaalaan hababka cusub ee habaynteeda iyo isbedbeddelka signal. signal in sireed farsamooyinka la dagaalanka khaladaadka ku jira xaalado fara, falalka bixiyaan faa'iido tamarta nidaamka 6.8 dB, inkastoo signal spectrum faafinta. Waxa uu isticmaalaa codes block: codes Hamming, Reed-Sulaymaan, BCH iyo geed codes convolutional. Isticmaalka An xiiso of codes loo baahan yahay in la tixgeliyo oo u oggolaan in ay ogaadaan wajiga Ilodanimada saddex xagal keying wareeg iyo sidaas helo faa'iido dheeraad ah sireed in la kordhiyo xawaaraha gudbinta signalka. Xaaladdan oo kale channel isticmaalka bandwidth multi-meel wajiga qaraabo keying wareeg iyo Ilodanimada inayan quadrature keying wareejin wajiga.

isgaarsiinta satellite

hababka isgaarsiinta Satellite waxaa loo isticmaalaa in satalayt geostationary for gudbinta barnaamijyada telefishanka, oo ay ku jiraan kuwa qaata qofka iyo gaadiidka xogta koox software. Waxa xusid gaar ah waa nidaamka caalamiga ah ee navigation badda satellite Inmarsat, taasoo, wuxuu haddana, ayaa helay isticmaalka ganacsi ballaaran isgaarsiinta degdeg ah iyo navigation la isticmaalayo nidaamka navigation satellite GPS a meelaha durugsan, ee xaaladaha degdegga ah, iyo sidoo kale la socodka gaadiidka xamuulka. Compact telefoonka satellite ogolaanaya kala iibsiga xogta ka meel kasta oo dunida ah. Isku dhafan oo buuq dacayadeed broadband ah ay muujin teknoolajiyada cusub ayaa laga fuliyay: antenna microstrip soo noqnoqoshada, kordhiyo adag gobolka xoog, filter a channel dual in la ruxruxo loomana baahno dusha ku salaysan germanate bismuth, filtarrada microwave narrowband in resonators dielectric, iwm ..

hab Isgaarsiinta

Maanta, gaar ahaan horumarka degdeg ah hababka isgaadhsiinta mobile heshay, tirada macaamiisha oo dalalka ugu badato tirada macaamiisha network go'an. Fadilmo Inta suuqa mobile heysta GSM-900 caadiga ah / 180, taas oo nidaamka gaadhay xadka oo kaamil ah iyadoo la adeegsanayo GPRS iyo EDGE technology ugu dambeeyay. Aad rajo waa in la tixgeliyaa sida nidaam mobile xidhiidhka la qeybinta code of channels CDMA kuwa gaarka ah la ekaan iyo waxqabadka tamarta. Maanta, si loo abuuro nidaam ah 3G mobile isgaadhsiinta iyada oo la raacayo caadiga ah iyo MT-2000, ay soo saareen Midowga Caalamiga ah ee Isgaarsiinta, adeegsanayaa saddex caadiga ah ku salaysan farsamada CDMA: CDMA ONE, CDMA 2000 iyo WCDMA. Iyadoo qayb ka ah ee caadiga ah IMT-2000 ka, shuqullada on abuurka ah ee satellite hababka isgaadhsiinta mobile shakhsi Orbocomm, Thuraya, Clobal Star, Iridium. Iyadoo howlgalka ganacsi ee nidaamka aan la gaari ay sabab u tahay dhibaatooyinka maalgelinta mashaariicda iyo dhibaatooyin farsamo. Wixii macluumaad shirkadaha xiriirinta si fiican u xaqiijiyay nidaamka radio DECT.

nidaamka gudbinta signal Fast

Thanks to horumarka technology microelectronics, macmalay oo loo isticmaalo maanta mobile iyo computer-xirka iyo isgaarsiinta, sida Bluetooth, ZigBee, WiMax, WiFi iyo kuwa kale. In dhaqanka, isticmaalka nidaamka gudbinta qalaad, kuwaas oo loo abuuray oo isticmaalaya mabaadiida guud iyo qorsheyaasha dhismaha iyo adapters channel kala duwan in ay ku xidhmaan u channels gudbinta dhiganta. nidaamka isgaarsiinta Hydroacoustic xiriiraan biyo la isticmaalayo vibrations ultrasonic in 8-20 Khz ka fogaan ah 4 km. hababka isgaarsiinta Laser isticmaali laser la Milanello a of 1-10 microns, oo loo isticmaalo in links bannaan. qalab samaynta geedka (Russia) soo saaray qalab Ryazan transceiver laser bixinta heerka gudbinta signal ah oo ku saabsan 200 Mbit / sec badan fogaan ah 2-10 km xaaladaha jidhadhka dhulka iyo sida loo isticmaalo tusaale ahaan gudbinta macluumaadka u dhaxeeya saldhigyada saldhig in nidaamka isgaarsiinta mobile. Nidaamka Isgaarsiinta ee sugnan iyo Asia ee isticmaalka dhulka hoostiisa (anteeno) cable, tus, shirkadaha EUPEN kala duwan inta jeer 30-1800 MHz ah. saynisyahano Maraykanka aasaasay suurtagalnimada ee gudbinta hirarka radio gektametrovogo kala duwan ee uurkii Dhulka. Waxaa la rumeysan yahay in inta lagu guda jiro meelaynta transponders gobolka ilaa 200 m la abuuri karaa link isgaadhsiinta gudbinta signal la spectrum ee ku saabsan 500 Hz ah.
