Tokom ovog prvog perioda testiranja, ruter je uspešno radio i ostao dovoljno stabilan za praktičnu upotrebu. Vreme neprekidnog rada (uptime) dostiglo je nekoliko dana bez kritičnih grešaka, što je pozitivan prvi signal za test primerak uređaja u ovoj klasi.\u003C\u002Fp>\n\u003Cp>Prvi utisak nije savršen, ali je uređaj očigledno koristan. Ruter nije uglađen mejnstrim proizvod, ali takođe nije ni igračka. To je dovoljno ozbiljna 5G OpenWrt platforma za nastavak testiranja.\u003C\u002Fp>\n\u003Ch2>Pakovanje: Prva slaba tačka\u003C\u002Fh2>\n\u003Cp>Najveće negativno iznenađenje bilo je pakovanje. Nažalost, kartonska kutija je bila slaba i previše mekana za uređaj ove težine i oblika. Sam ruter čak nema ni oštre ivice, ali je ipak uspeo da probije unutrašnji kartonski kalup i lako ga ošteti.\u003C\u002Fp>\n\u003Cp>Na sreću, uređaj je isporučen u dvostrukom pakovanju, tako da je sam ruter stigao bezbedno. Ipak, ovo je važna tačka: tehnički dobar uređaj zaslužuje bolje pakovanje, posebno ako je ikada namenjen za profesionalnu prodaju u Evropi.\u003C\u002Fp>\n\u003Ch2>Da li se proizvod sa OpenWrt 21 i danas može kupiti?\u003C\u002Fh2>\n\u003Cp>Ovo je jedno od centralnih pitanja. OpenWrt 21.02 je star, a testirani firmver nije čisto zvanično (upstream) OpenWrt izdanje, već verzija specifična za proizvođača. To ne čini ruter automatski lošim. Zapravo, trenutni fabrički firmver je funkcionalan i dovoljno stabilan za testiranje. Ali to otvara pitanja o bezbednosnim ažuriranjima, dugoročnom održavanju, upravljanju modemom i budućim putevima nadogradnje.\u003C\u002Fp>\n\u003Cp>Za privatni test uređaj, OpenWrt 21 može biti prihvatljiv ako sistem radi, modem je stabilan i uređaj nije neoprezno izložen. Za profesionalni proizvod ili veću primenu, to je prihvatljivo samo ako je putanja firmvera jasna: slika za oporavak (recovery image), metod nadogradnje, podrška za modem, upravljanje dual-SIM GPIO pinovima i stabilno vraćanje na prethodnu verziju (rollback) moraju biti verifikovani.\u003C\u002Fp>\n\u003Cp>Sledeći testovi će se stoga fokusirati na druge opcije firmvera, dijagnostiku modema, preusmeravanje u slučaju otkaza SIM kartice (SIM failover), zaključavanje frekvencijskih opsega i na to da li moderniji sistem zasnovan na OpenWrt-u može poboljšati uređaj bez narušavanja njegove 5G i dual-SIM funkcionalnosti.\u003C\u002Fp>\n\u003Ch2>Šta ovaj ruter čini zanimljivim\u003C\u002Fh2>\n\u003Cp>ZBT Z8102AX je zanimljiv jer se nalazi između potrošačkih rutera i industrijskih uređaja. Nije tako doteran kao vrhunski potrošački ruter, ali je otvoreniji, fleksibilniji i tehnički zanimljiviji od mnogih zatvorenih 5G rutera na tržištu.\u003C\u002Fp>\n\u003Cul>\u003Cli>5G modem sa RM500U-EA\u003C\u002Fli>\u003Cli>Dual-SIM hardver\u003C\u002Fli>\u003Cli>Sistem zasnovan na OpenWrt-u\u003C\u002Fli>\u003Cli>Više Ethernet portova\u003C\u002Fli>\u003Cli>Koristan za mobilni internet, rezervnu vezu (failover) i homelab scenarije\u003C\u002Fli>\u003Cli>Bolje prilagođen naprednim korisnicima nego početnicima\u003C\u002Fli>\u003C\u002Ful>\n\u003Ch2>Tržišna cena i pozicioniranje\u003C\u002Fh2>\n\u003Cp>Ruter poput ovog ne bi trebalo da bude pozicioniran kao jeftina plastična 5G kutija. Uz OpenWrt, pravi 5G modem, dual-SIM hardver i višestruke Ethernet portove, realna tržišna vrednost može se kretati u rasponu od 300 do 400 EUR, u zavisnosti od kvaliteta firmvera, dokumentacije, pakovanja, garancije i podrške.\u003C\u002Fp>\n\u003Cp>U isto vreme, ovo tržište će verovatno postati agresivnije. Samo je pitanje vremena kada će se slični uređaji pojaviti u većem broju i kada će prodavci početi da snižavaju cene. Ali to ne znači automatski i bolju vrednost. Kod ove vrste hardvera, jeftinije lako može postati skuplje ako su kvalitet, pakovanje, firmver, oporavak i stabilnost modema slabi.\u003C\u002Fp>\n\u003Ch2>Izabrana konfiguracija i sledeći hardverski korak\u003C\u002Fh2>\n\u003Cp>Ova testna jedinica je izabrana u specifičnoj konfiguraciji sa RM500U-EA modemom i dual-SIM hardverom. Sledeći korak neće ponovo biti ruter iste klase, već jači Wi-Fi 7 uređaj sa moćnijom četvorojezgarnom platformom. Cilj je da se ovaj prvi uzorak uporedi sa uređajem novije generacije i da se sledeći put, nadamo se, napravi bolja konfiguracija.\u003C\u002Fp>\n\u003Cp>Stabilnija politika cena, čistiji put razvoja firmvera i bolje pakovanje bili bi od suštinskog značaja ako bi ovakav uređaj ikada trebalo da postane deo ozbiljne proizvodne strategije. Prvi uzorak je koristan kao uređaj za učenje. Drugi uzorak bi trebalo da bude bliži budućem pravcu: Wi-Fi 7, jači procesor, bolji I\u002FO i zrelije OpenWrt okruženje.\u003C\u002Fp>\n\u003Ch2>Zaključak\u003C\u002Fh2>\n\u003Cp>ZBT Z8102AX nije savršen, ali je dobar i zanimljiv komad hardvera. Uspešno je i relativno stabilno radio u prvom testnom periodu. Uređaj dokazuje da ova klasa 5G OpenWrt rutera ima stvarni potencijal, posebno za napredne korisnike, konfiguracije mobilnih mreža i scenarije rezervne veze (failover).\u003C\u002Fp>\n\u003Cp>Loše pakovanje, stari fabrički firmver i nejasan dugoročni put nadogradnje sprečavaju ga da bude gotov premijum proizvod. Ali kao prvi uzorak, veoma je vredan.
