Zvichienderana nemakore ekutsvagisa uye ruzivo rwekusimudzira mumidziyo yeInternet, takakurukura matekinoroji nemhinduro dzeimba Broadband indoor network quality assurance.Chekutanga, inoongorora mamiriro azvino emumba Broadband indoor network mhando, uye inopfupisa zvinhu zvakasiyana senge fiber optics, magedhi, marouters, Wi-Fi, uye mashandiro emushandisi ayo anokonzera kumba Broadband indoor indoor network matambudziko.Kechipiri, iyo nyowani yemukati yekuvhara tekinoroji matekinoroji akaiswa neWi-Fi 6 uye FTTR (Fiber Kukamuri Kamuri) ichaunzwa.
1. Ongororo yemba Broadband indoor network matambudziko emhando
Mukuita kweFTTH (fiber-kumba-kumba), nekuda kwesimba rekutapurirana chinhambwe, kupatsanurwa kwemaziso uye kurasikirwa kwechishandiso, uye kubhenda kwefiber, simba rekuona rinogashirwa negedhi rinogona kunge rakaderera uye mwero wekukanganisa unogona. kuve yakakwira, zvichikonzera kuwedzera kweyero yekurasikirwa kwepaketi yekumusoro-layer sevhisi yekufambisa., chiyero chinodonha.
Nekudaro, kuita kwehardware yemagedhi ekare kunowanzo kuderera, uye matambudziko akadai seyakakwira CPU uye ndangariro kushandiswa uye kupisa kwemidziyo zvinowanzoitika, zvichikonzera kudzoreredza kusingaite uye kubondera kwemagedhi.Magedhi ekare kazhinji haatsigire gigabit network kumhanya, uye mamwe magedhi ekare anewo matambudziko akadai sechinyakare machipisi, izvo zvinotungamira kune gaka rakakura pakati peiyo chaiyo yekumhanyisa kukosha kweiyo network yekubatanidza uye kukosha kweiyo theoretical, iyo inowedzera miganhu mukana wekuvandudza ruzivo rwemushandisi online.Parizvino, iwo ekare akangwara epamba magedhi akashandiswa kwemakore matatu kana anopfuura pane mhenyu network achiri kutora imwe chikamu uye anoda kutsiviwa.
Iyo 2.4GHz frequency bhendi ndiyo ISM (Industrial-Scientific-Medical) frequency bhendi.Inoshandiswa seyakajairwa frequency bhendi yeredhiyo senge isina waya yenzvimbo network, isina waya yekupinda system, Bluetooth system, point-to-point kana point-to-multipoint spread spectrum communication system, ine mashoma frequency zviwanikwa uye shoma bandwidth.Parizvino, kuchine chimwe chikamu chemagedhi anotsigira 2.4GHz Wi-Fi frequency bhendi munetiweki iripo, uye dambudziko re-co-frequency / pedo nefrequency interference rinonyanya kuoneka.
Nekuda kwemasoftware bugs uye kusakwana kwekuita kwehardware kwemamwe magedhi, PPPoE yekubatanidza inogara ichidonhedzwa uye magedhi anogara achitangwa patsva, zvichikonzera kukanganisa kazhinji kwekuwana Internet kwevashandisi.Mushure mekunge PPPoE yekubatanidza yavhiringwa zvishoma (semuenzaniso, iyo uplink transmission link yavhiringwa), yega yega yekugadzira gedhi ine isingaenderane yekumisikidza zviyero zvekuonekwa kwechiteshi cheWAN uye kuitazve kufona kwePPPoE.Mamwe magedhi evagadziri anoona kamwe chete masekonzi makumi maviri, uye anodhindazve chete mushure mekunge makumi matatu atadza kuonekwa.Nekuda kweizvozvo, zvinotora maminetsi gumi kuti gedhi ritange otomatiki PPPoE replay mushure mekungoenda kunze kwenyika, zvichikanganisa zvakanyanya ruzivo rwemushandisi.
Magedhi emusha evashandisi akawanda anogadziriswa nema routers (achazonzi "marouta").Pakati pemarouter aya, akati wandei anotsigira 100M WAN ports, kana (uye) anotsigira Wi-Fi 4 chete (802.11b/g/n).
Mamwe ma routers evagadziri achine imwe chete yeWAN ports kana Wi-Fi protocol inotsigira Gigabit network kumhanya, uye inova "pseudo-Gigabit" routers.Pamusoro pezvo, iyo router yakabatana negedhi kuburikidza netambo yetiweki, uye tambo yetiweki inoshandiswa nevashandisi ndeye chikamu 5 kana super chikamu 5 tambo, ine hupenyu hupfupi uye isina simba yekudzivirira-kupindira, uye mazhinji acho chete. tsigira 100M kumhanya.Hapana kana imwe yemarouter ataurwa pamusoro uye tambo dzetiweki dzinogona kusangana nezvinodiwa zvekushanduka kweanotevera gigabit uye super-gigabit network.Mamwe ma router anotangazve kazhinji nekuda kwematambudziko emhando yechigadzirwa, zvichikanganisa zvakanyanya ruzivo rwemushandisi.
Wi-Fi ndiyo nzira huru yekuvhara isina waya yemukati, asi magedhi mazhinji epamba anoiswa mumabhokisi emazuva ano asina simba pamusuwo wemushandisi.Yakaganhurirwa nenzvimbo yebhokisi razvino risina simba, zvinhu zvevhavha, uye yakaoma imba mhando, iyo Wi-Fi chiratidzo haina kukwana kuvhara zvese zvemukati.Iyo iri kure iyo terminal mudziyo unobva kune yeWi-Fi yekupinda nzvimbo, iyo yakawanda zvipingamupinyi iripo, uye yakakura kurasikirwa kwesimba rechiratidzo, izvo zvinogona kutungamira kune kusagadzikana kubatana uye kurasikirwa kwepaketi yedata.
Panyaya yemukati metiweki yemidziyo yakawanda yeWi-Fi, matambudziko akafanana-frequency uye ari padyo-channel yekukanganisa anowanzoitika nekuda kwezvisinganzwisisike magadzirirwo echiteshi, zvichiwedzera kuderedza chiyero cheWi-Fi.
Apo vamwe vashandisi vanobatanidza router kune gedhi, nekuda kwekushaya ruzivo rwemhizha, vanogona kubatanidza router kune isiri-gigabit network port yegedhi, kana kuti vangave vasingabatanidzi tambo yetiweki zvakasimba, zvichiita kuti vasununguke network ports.Muzviitiko izvi, kunyange kana mushandisi akanyorera ku gigabit sevhisi kana kushandisa gigabit router, haakwanise kuwana yakagadzikana masevhisi egigabit, ayo anounzawo matambudziko kune vanoshanda kuti vatarise zvikanganiso.
Vamwe vashandisi vane michina yakawandisa yakabatana neWi-Fi mudzimba dzavo (kupfuura makumi maviri) kana akawanda maapplication ekudhawunirodha mafaera nekumhanya kwakanyanya panguva imwe chete, izvo zvinokonzeresa kwakakomba chiteshi cheWi-Fi uye kusagadzikana kweWi-Fi kubatana.
Vamwe vashandisi vanoshandisa materminals ekare anongotsigira chete-frequency Wi-Fi 2.4GHz frequency band kana ekare Wi-Fi protocol, saka havagone kuwana yakagadzikana uye inokurumidza ruzivo rweInternet.
2. New matekinoroji ekuvandudza indoor network Hunhu
Yakakwira-bandwidth, yakaderera-latency masevhisi akadai se4K/8K yakakwira-tsanangudzo vhidhiyo, AR/VR, dzidzo yepamhepo, uye hofisi yemba zvishoma nezvishoma zvinova izvo zvakaomarara zvinodiwa nevashandisi vemba.Izvi zvinoisa kumberi kwepamusoro zvinodiwa pamhando yeimba yebroadband network, kunyanya mhando yeimba yebroadband indoor network.Iyo iripo imba Broadband indoor network yakavakirwa paFTTH (Fiber KuImba, faibha kuenda kumba) tekinoroji yave yakaoma kuzadzisa zvinodiwa pamusoro apa.Nekudaro, Wi-Fi 6 uye FTTR matekinoroji anogona kuzadzisa zviri pamusoro pesevhisi zvinodiwa uye inofanira kuiswa pamwero mukuru nekukurumidza sezvinobvira.
