Introduction of the new generation TR-398 test system WTE NE

I-TR-398 iyindinganiso yokuhlolwa kokusebenza kwe-Wi-Fi yangaphakathi ekhishwe yi-Broadband Forum ku-Mobile World Congress 2019 (MWC), iyindinganiso yokuqala yokuhlola ukusebenza komthengi wasekhaya we-AP Wi-Fi. Ezingeni elisanda kukhishwa ngo-2021, i-TR-398 inikeza isethi yamacala okuhlola ukusebenza anezimfuneko ze-PASS/FAIL zokusetshenziswa okungu-802.11n/ac/ax, ezinohlu olubanzi lwezinto zokuhlola kanye nezilungiselelo ezichazwe ngokucacile zolwazi lokusetha ukuhlolwa, amadivayisi asetshenzisiwe. , kanye nezindawo zokuhlola. Ingasiza ngempumelelo abakhiqizi ukuthi bahlole ukusebenza kwe-Wi-Fi kwamasango asekhaya asendlini, futhi izoba indinganiso yokuhlola ehlanganisiwe yokusebenza kokuxhumeka kwenethiwekhi ye-Wi-Fi esikhathini esizayo.

I-Broadband Forum iyinhlangano yemboni yamazwe ngamazwe engenzi nzuzo, eyaziwa nangokuthi i-BBF. Okwandulelayo kwakuyi-DSL Forum eyasungulwa ngo-1999, futhi kamuva yathuthukiswa yaba yi-BBF yanamuhla ngokuhlanganisa izinkundla ezimbalwa ezifana ne-FRF ne-ATM. I-BBF ihlanganisa abaqhubi, abakhiqizi bemishini, izinhlangano zokuhlola, amalabhorethri, njll., emhlabeni wonke. Ukucaciswa kwayo okushicilelwe kufaka phakathi amazinga enethiwekhi yekhebula njenge-PON, VDSL, DSL, Gfast, futhi anethonya elikhulu embonini.

TR-398 Ifomu lokuhlola lakamuva

I-WTE-NE Isingeniso Somkhiqizo:
Njengamanje, isixazululo sokuhlola sendabuko emakethe sokuxazulula indinganiso ye-TR-398 sidinga ukusebenzisana kwabakhiqizi abahlukahlukene, futhi uhlelo lokuhlola oluhlanganisiwe luvame ukuba lukhulu futhi luthatha izinsiza eziphezulu. Ngaphezu kwalokho, kukhona futhi uchungechunge lwezinkinga ezifana nokusebenzisana okungaphelele kwedatha yokuhlola ehlukahlukene, ikhono elilinganiselwe lokuthola izinkinga, nezindleko eziphezulu zalo lonke uhlelo. Uchungechunge lwemikhiqizo ye-WTE NE eyethulwe i-BTF Testing Lab ingakwazi ukubona ukushintshwa okuphelele kwamathuluzi avela kubakhiqizi abahlukahlukene, futhi ivule wonke amaphrojekthi okuhlola kuso sonke isixhumanisi ukusuka kusendlalelo se-RF kuya kusendlalelo sohlelo lokusebenza ethuluzini elilodwa. Ixazulula kahle inkinga yokuthi ithuluzi lendabuko alinakho ukusebenzisana kudatha yokuhlola, futhi lingaqhubeka nokuhlaziya imbangela yenkinga ngenkathi lisiza umsebenzisi ukuthi athole inkinga. Ngaphezu kwalokho, umkhiqizo unganikeza abasebenzisi izinsiza zokuthuthukisa ezenziwe ngokwezifiso ezijulile ngokususelwe kusitaki sephrothokholi evamile, futhi usebenzise ngempela izidingo zangempela zabasebenzisi emisebenzini ethile yokuhlola yethuluzi.

I-emulator yenethiwekhi ye-WIFI

I-NE okwamanje isekela zonke izimo zokuhlola ze-TR-398 futhi ingasekela ukukhiqizwa kokuhlola okuzenzakalelayo okukodwa kwemibiko yokuhlola.

Isethulo sephrojekthi yokuhlola ye-NE TR-398

·I-WTE NE inganikela ngezinkulungwane ze-802.11 kanyekanye kanye nokulingisa kwethrafikhi nabasebenzisi be-Ethernet, ngaphezu kwalokho, ukuhlaziywa kwesivinini esiqondile kungenziwa ezicini zesistimu yokuhlola.
·I-chassis ye-WTE NE ingahlelwa ngamamojula okuhlola afika kwangu-16, ngalinye elizimele ekukhiqizeni ithrafikhi nokuhlaziywa kokusebenza.
·Imojula ngayinye yokuhlola ingalingisa abasebenzisi abangu-500 be-WLAN noma be-Ethernet, abangaba ku-subnet eyodwa noma ama-subnet amaningi.
·Inganikeza ukulingisa kwethrafikhi nokuhlaziya phakathi kwabasebenzisi be-WLAN, abasebenzisi/amaseva e-Ethernet, noma abasebenzisi be-WLAN abazulazulayo.
·Ingahlinzeka ngesivinini esigcwele se-Gigabit Ethernet traffic sekulingisa.
·Umsebenzisi ngamunye angasingatha ukugeleza okuningi, ngakunye okunikeza okuphumayo ku-PHY, MAC, kanye nezendlalelo ze-IP.
·Ingahlinzeka ngezibalo zesikhathi sangempela zechweba ngalinye, izibalo zokugeleza ngakunye, nolwazi lokuthwebula iphakethe, ukuze kuhlaziywe ngokunembile ngabasebenzisi.

6.2.4 Ukuhlolwa Kwe-Dual-band throughput

6.2.2 Ukuhlolwa Okuphezulu Kwempumelelo

6.3.1 Ukuhlolwa kweRange Versus Rate

I-WTE NE ingabona ukusebenza okubukwayo nokuhlaziywa kwemiphumela yokuhlolwa ngesofthiwe yekhompuyutha ephezulu, futhi iphinde isekele imibhalo yamacala okusetshenziswa ezenzakalelayo, engaqedela wonke amacala okuhlola we-TR-398 ngokuchofoza okukodwa futhi ikhiphe imibiko yokuhlola ezenzakalelayo. Konke ukulungiselelwa kwepharamitha yethuluzi kungalawulwa yimiyalelo ye-SCPI ejwayelekile, futhi uvule isixhumi esibonakalayo sokulawula esihambisanayo ukuze kube lula abasebenzisi ukuthi bahlanganise imibhalo yecala lokuhlola elizenzakalelayo. Uma kuqhathaniswa nezinye izinhlelo zokuhlola ze-TR398, i-WTE-NE ihlanganisa izinzuzo zeminye imikhiqizo emakethe namuhla, hhayi nje ukuqinisekisa ukuthi ukusebenza kwesofthiwe kulula, kodwa futhi kuthuthukisa uhlelo lokuhlola jikelele. Ngokusekelwe kubuchwepheshe obuyinhloko bemitha ngokwayo ukuze kukale ngokunembile amasiginali angenantambo abuthaka kuze kufike ku- -80 DBM, lonke uhlelo lokuhlola lwe-TR-398 luncishiswa lube imitha elilodwa le-WTE-NE kanye negumbi elimnyama le-OTA. Uchungechunge lwezingxenyekazi zekhompuyutha zangaphandle ezifana ne-test rack, i-attenuator ehlelekayo kanye nejeneretha yokuphazamisa ziyasuswa, okwenza yonke indawo yokuhlola ibe mfushane kakhulu futhi ithembeke.
