Ezingxenyeni zekhompiyutha, ukukhishwa kwamandla ukulahlekelwa kwamandla esignali wokuxhumana okulinganiselwe kuma- decibel (dB) . Enye yezindlela ezisetshenziselwa ukwandisa amandla esignali ukuvimbela ukugodla kukhishwa .
Ukunqatshwa Kuhloswe
Ukwehliswa kwenzeka kumanethiwekhi ekhompyutha ngezizathu eziningana:
- ububanzi - kokubili ukuxhumana okungenazintambo nokungenawo ucingo kancane kancane kwehla amandla ngamandla ngaphezulu
- ukuphazanyiswa - kumanethiwekhi angenawaya, ukuphazamiseka komsakazo noma ukuvinjelwa ngokomzimba njengezindonga futhi kunciphisa izimpawu zokuxhumana
- usayizi wocingo - kumanethiwekhi wensimbi, izintambo ezincane zihlushwa yizintambo eziphakeme (ngaphezulu) kunezintambo ezinamandla
Kumanethiwekhi e- DSL , izinyathelo zokunciphisa umugqa zibonisa ukulahlekelwa phakathi kwekhaya kanye ne-DSL iphuzu lokufinyelela (umshintsho ophakathi). Ukwehliswa kubaluleke kakhulu kumanethiwekhi e-DSL njengoba izinga lamanani umndeni onikeziwe lingathola kungavinjelwa uma amanani okunciphisa umugqa kakhulu kakhulu. Izindinganiso ezijwayelekile zokwehliswa komugqa oxhumano lwe-DSL ziphakathi kuka-5 dB no-50 dB (amanani aphansi angcono). Amanye ama-router e-broadband abonisa amanani okunciphisa imigqa emakhasini awo e-console, nakuba afisa ukuba nesithakazelo kuphela kubaphathi benethiwekhi abaphambili lapho bexazulula izinkinga zokuxhuma
I-Wi-Fi isekela isici esibizwa nge- dynamic rate scaling eguqulela ngokuzenzakalelayo izinga eliphezulu le-data lokuxhuma phezulu noma phansi ngezinyathelo ezihleliwe kuye ngokuthi ikhwalithi yokudluliswa komugqa. Ezingxenyeni eziphakeme zokunakekelwa, uxhumano lwe-54 Mbps lungalinganisa phansi njenge-6 Mbps, isibonelo.
Igama elithi "ukunqunywa" ngezinye izikhathi lisebenza kwezinye izindawo ngaphandle kwamanethiwekhi wekhompyutha. Isibonelo, ama-audiophiles nabachwepheshe bezwi abahle bangasebenzisa amasu okuvimbela ukuphatha amazinga womsindo uma behlanganisa ukuqoshwa komsindo okuhlukene ndawonye.
Ukuphambaniswa kufakazelwa
Ukukhuliswa kwesignali kusebenza ngokuphikisana nokunqunywa kwesibonakaliso, ukwandisa ugesi amandla esignali yelayini nganoma yiziphi izindlela ezimbalwa zobuchwepheshe. Izinhlobo ezihlukahlukene zokukhulisa zethula umsindo ophansi noma ongena ngaphansi kwesignali. Emanethiwekhi ekhompiyutha, ukukhulisa ngokuvamile kuhlanganisa logiyothi ukunciphisa umsindo ukuqinisekisa ukuthi idatha yomlayezo oyisisekelo ayitholakali kwinqubo.
Amadivaysi wokuphindaphinda kwenethiwekhi ngokuvamile ahlanganisa i-amplifier yesignali kuma-circuitry awo. Umphindaphindi usebenza njengemaphakathi phakathi kokuphela kokugcina komlayezo. Ithola idatha kusuka kumthumeli wangempela (noma enye ibuyele phezulu), iyisebenzise ngokusebenzisa i-amplifier, bese idlulisela isignali enamandla phambili ekugcineni kwayo.
Okuthiwa yizibonakaliso zesikhangiso kusiza ukukhulisa izibonakaliso ezingenantambo ezitholwa. Ngaphandle kwama-repeaters, ama-antenna aqondiswayo nokunye ukuthuthukiswa kwe-antenna kusebenza kahle njengama-boosters.
Umqondo ohlukile ovela kuphawu lokukhulisa, ukuvuselelwa kwe-DNS wuhlobo lokusabalalisa kwe- Distributed Denial of Service (DDoS) lapho umhlaseli ononya noma i- botnet esebenzisa i- Domain Name System (DNS) ukukhukhumeza iseva elibhekene nedatha yomlayezo oyimfihlo. Ukuphambanisa, kulokhu, kubhekisela ekuziphatheni kwe-DNS ekuphenduleni imiyalezo emincane yokucela ngokuthumela idatha eningi kakhulu yempendulo.
Igama elithi p rivacy amplification (ehlukaniswe kokubili isignali ne-DNS amplification) libhekisela kumqondo ophambili ekuvikelekeni kwenethiwekhi yekhompyutha kanye nencazelo yolwazi lapho amaqembu amabili angasebenza ndawonye ukuze ahlukanise inani lekhiye eyimfihlo.
