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

I-TR-398 ngumgangatho wokuvavanya ukusebenza kwe-Wi-Fi yangaphakathi ekhutshwe yi-Broadband Forum kwi-Mobile World Congress 2019 (MWC), ngumgangatho wokuqala wokuvavanya umthengi we-AP Wi-Fi kushishino. Kumgangatho osanda kukhutshwa ngo-2021, i-TR-398 ibonelela ngeseti yeemeko zovavanyo lokusebenza kunye neemfuno ze-PASS/FAIL ze-802.11n/ac/ax ukuphunyezwa, kunye noluhlu olubanzi lwezinto zovavanyo kunye neSetingi ezichazwe ngokucacileyo zolwazi lokuseta uvavanyo, izixhobo ezisetyenzisiweyo. , kunye neemeko zovavanyo. Inokunceda ngokusebenzayo abavelisi ukuba bavavanye ukusebenza kwe-Wi-Fi yamasango asekhaya angaphakathi, kwaye iya kuba ngumgangatho odibeneyo wovavanyo womsebenzi wonxibelelwano lwe-Wi-Fi yasekhaya kwixesha elizayo.

IForam yeBroadband ngumbutho wamazwe ngamazwe ongenzi nzuzo, okwaziwa njenge-BBF. Eyandulelayo yayiliQonga le-DSL elasekwa ngo-1999, kwaye kamva laphuhliswa libe yi-BBF yanamhlanje ngokudibanisa iiforam ezininzi ezifana ne-FRF kunye ne-ATM. I-BBF imanyanisa abaqhubi, abavelisi bezixhobo, imibutho yovavanyo, iilabhoratri, njl., kwihlabathi liphela. Inkcazo epapashiweyo ibandakanya imigangatho yenethiwekhi yentambo efana ne-PON, i-VDSL, i-DSL, i-Gfast, kwaye inempembelelo enkulu kwishishini.
