Abaphindayo - ntoni na? Abaphindayo: uqwalaselo, ukufakela, imo

uphawu ngasinye ngokuthe udlulele emajukujukwini. Kodwa impucuko yethu kakhulu ebotshelelwe yokuba yonke idatha ezibhaliweyo kuyo ngendlela engqinelana. Nendlela yokwenza oko? Ngoko ke kufuneka into ukuqinisa okanye ukuphinda. Nantso selisiza ukuya uncedo umzila-okuphindwa kweklasi. Yintoni na? Ingaba isebenza njani? Ziziphi iindlela ukucwangcisa njani? Nalu uluhlu elifutshane izinto ingqalelo.

Abaphindayo - yintoni na apho isicelo?

Ekuqaleni, siya ukuqonda imigaqo. GSM zabaphindayo kunye zabaphindayo msindo Imiqondiso cellular ukuba iyafuneka ukwandisa ekuhlaleni kwindawo yayo network. Oku izixhobo radio entsonkothileyo esebenzayo electronic ukuba kusebenza kunye iintambo sokuquqa kwerediyo kunye eriyali. Ezi zixhobo kufuneka ngokuzimeleyo isicelo nawuphi na umsebenzisi womnatha. Eyona nto ibalulekileyo kukuba akukho mfuneko yokuba afumane imvume okanye umdla operator mobile xa kukho umnqweno ukusebenzisa GSM okuphindwa kweklasi. Oko kukuthi, ukuba sele esaziva ngabo ezi ndaba, makhe sithethe kancinci xa iyavakala yokuzisebenzisa.

isicelo

Sebenzisa zabaphindayo kucetyiswa kwiimeko ezinjalo:

1. Xa kufuneka ukuba ufumane uqhagamshelwano isitali kwindawo apho yolwamkelo ubuthathaka (emaphandleni okanye kude kakhulu kuwo umzi). Apha ingxaki iyatyhilwa yi-eriyali zomzimba, nto leyo liphezulu kwaye directivity elibukhali kwicala elinye.
2. Ukugcina umgangatho wonxibelelwano kwindawo ukuba isixhobo eso sikhuseleke xa enendawo okanye isakhiwo structure (s) of. Yintoni ebalulekileyo indawo ye-antenna xa Phawleka fowni line ngqo.

Abaphindayo asetyenziswa emgodini namanqanaba komhlaba izakhiwo ezahlukeneyo (amaziko zokuthenga). Njengomgaqo, baxhasa kuphela olunye uluhlu yonxibelelwano: GSM-1800, nge okanye ubukho GSM-900.Takzhe yezixhobo ezinjalo nempembelelo entle ngexesha lomsebenzi ngaphandle uyazihlaziya phones ngenxa yokuba akukho mfuneko yokuba ukukhangela umqondiso nzima. Ngokunciphisa kuphazamiseka kwezinye iisekethe radio-elektroniki kule ndawo, bezisetyenziselwa-moya umkhweli. Kwenzeka ukuba, kwimowudi yabafundi abaphindayo, ungakwazi ukuguqula ezinye kwesinye isixhobo.

isimiso ukusebenza

njani a zabaphindayo? Oko kukuthi ukusuka kwindawo eyakhayo mbono? Esi sixhobo sibenokubizwa njengendawo msindo kabini owenza lebhokisi abanikelayo kunye nenkonzo eriyali, ngelixa esenza ulungiso amaza. Kwaye ke wokuqala ufumana idata esuka kwisiseko sesikhululo kunye icacisa zabaphindayo kwaye edlulisela ukuba owesibini, kwaye sele apha ulwazi luthunyelwe nefowuni. Ingxelo leyo isebenza efanayo. Ukwenzela ukuphepha ifuthe self-excitation kunye Ukubolekisa data phakathi kwe-eriyali kwakufuneka bodwa olungileyo umoya phakathi kwabo. Kodwa oku ke Acme yogqibelelo - kukho abameli ngcono ngokuba iklasi. Reception kunye nokudlulisela ulwazi kuwo ziveliswa kwintlanganiso zitsho eyahlukileyo. Ngoko ke ngaphandle ingozi isiphumo self-excitation. Baphinda ngokwabo, nangona elula zayo, ube ukhuseleko ethembekileyo nxamnye iimpembelelo ezingalunganga le nkqubo. Yiloo yonke umgaqo kule fowuni. Ndiyathemba ukuba imiba ephambili kule moya ziphelisiwe, kwaye uvale isihloko malunga okuphindwa kweklasi. Yintoni na - sele siyazi thina, Hamba uye kuzimela kulaa fakelo kunye nokusebenza.

ukufakwa

Njani na ekutshoneni okuphindwa kweklasi? Kufuneka beka ifowni kwindawo othe tyaba. Kuyimfuneko ukuqinisekisa indlela ngaphandle umoya ehlabathini abaphindayo radiator. Esondele ngu akumele amalahle izixhobo. Qhoboshela i-eriyali kunye bayibeke phezu iintambo RF okuphindwa kweklasi. Plug-in ngokunxulumene kufuneka zigqunyiwe ngobunono lithetha okhethekileyo: germolenty kunye abicah sealant. Uya kuqalisa nini zabaphindayo, kufuneka uqiniseke ukuba ukuhlola enoba kukho uphawu ukusuka kwisiseko sesikhululo. I-eriyali kufuneka licwangciswe ukuze afumane umqondiso ilungileyo kumsebenzisi oyifunayo. Ukuba ufuna ukusebenzisa iinkonzo eziliqela kubo, sikhokelwa nabo imiyalezo olubuthathaka kakhulu.

Dibanisa i-eriyali kunye okuphindwa kweklasi. Kulo mzekelo, ukuqinisekisa ukuba iindawo ezi HF ecocekileyo. Ukuba ngaphakathi kukho uthuli okanye ubumanzi, sebenzisa i swab yomqhaphu okanye ngelaphu ogalelwe ioli ngokukhuhla utywala ngaphambili, uze emva koko loma. Ukuqhagamshela kwinethiwekhi iadaptha. Ukusuka kwakhe sele enxulumene okuphindwa kweklasi. Ngenxa yoko, ifowuni ngoku kumiselwa kwaye eziqhutshwa. Kodwa phambi kwalonto kufuneka ukhethe ukuba uza kusebenza njani. Qala ukuba wenze le nkqubo ngokungqinelana iindlela ngezantsi kunokwenzeka.

Access Point imo Access Point (AP)

Wasebenzisa isixhobo ukwenza njengoko a wireless Wi-Fi ephathekayo. Apha, yonke into ebotshelelwe SSID. Ngoko ke, ukuba ufuna ukuya emsebenzini ngenxa yokuba ifowuni, kufuneka ufake yonke uqhagamshelo kwinethiwekhi yedatha.

Wireless Bridge mode Wireless Bridge

Kuyimfuneko ukuba ukuqhagamshela networks ezimbini ezizimeleyo kwentambo. Kwakhona, le imo inokufana ulwandiso kweengcingo Ethernet eziya ukuqhagamshela iinxalenye ezimbini lonke. Akwanelanga ukuba uyivule nje, wabeka imida efunekayo - kwaye unako ukusebenza.

imo AP / Bridge (AP + Bridge)

It idibanisa iingenelo iimpawu zangaphambili. Kukho nazo zibonelelwe esebenza, apho kungenzeka leeyunithi ezintathu okanye ngaphezulu engasebenzi ngeengcingo.

imo zabaphindayo Wireless abaphindayo (Bridge / zabaphindayo)

Kuyimfuneko ukuba ukudibanisa iingongoma ezimbini kwindawo apho uxhulumaniso ngqo phakathi kwabo akwenzeki. Enyanisweni, lo imo lisetyenziswa bahlabe iisignali zerediyo phakathi kwabo. Ngaphezu koko ehlobene asenokuba ziingongoma ngaphezu ezimbini / bridge, yaye kangangoko kunokwenzeka ukudala i "ikhonkco", ngokusekelwe kwi - i abaphindayo. Ntoni na, ndiyacinga, akukho mfuneko ukuchaza. Ukuze wenze oku, kufuneka ufake i parameters ekuchongeni ukuqala isixhobo.

Ibhena Mode (Ibhena)

Oku self-kulungelelana, yaye ukongeza Access Point. Ukuba kukho iindawo zokungena ezininzi nabathengi athile ukuhamba phakathi iinkalo impembelelo yabo, inkqubo ukhetha ukusebenza ngalowo mnye esibonelela umqondiso omkhulu. ukuzula umsebenzi kukuba ukuqokelela ukudlulisela ulwazi kwizikhululo ngeengcingo. Ngenxa kule umsebenzisi akayi kuvakalelwa kukuba ngendlela ngamaxesha kwenzeka, kuba nangoko aye kwenye indawo.

isiphelo

Ngoko ke "ukuqonda" yabafundi abaphindayo, oko kukuthi, kunye nezinye izinto ezininzi. Uncedo Kubalulekile ukuba esi sixhobo nje kuphela ukusebenza, kodwa kwakhona lula ukubeka up. Ngokuqhelekileyo, ukuba uqwalasele isixhobo, kufuneka ufake kuphela isiqu, apho nendlela ukudibanisa - kwaye oku kakhulu ngokwaneleyo, kuba yonke enye into uzenza zabaphindayo wifi. Yintoni na, kwakunye zenzeke kwaxoxwa lonke eli nqaku, ngoko ke ngoku sisele kunye kwanyanzeleka ukuba kuthi ndlela-ntle.
