5km Point to Point Outdoor CPE O4 5GHz Long Range Outdoor CPE is designed to WISP CPE solutions and long distance wireless network solutions for video surveillance and data transmission. It features with 14dBi directional antenna to provide an efficient way to pick up and maintain a stable signal for a wireless network. Adopt of auto-bridging technology,two CPE can connect to each other automatically to make it easy to setup. O4 adopts of independent power amplifier and 14dBi directional antenna to provide an efficient way to pick up and maintain a stable signal for a wireless network up to 5km. Super channel-Extended Frequency O4 adopt of Qualcomm AR9344 chipset and special software mechanism optimization for radio driven architecture to offer extended frequency support. This feature is designed to help users get out of the congested, unlicensed 5GHz band and into clean spectrum. TD-MAX-TendaTDMA proprietary protocol TD-MAX is Tenda TDMA (Time Division Multiple Access) proprietary protocol to improve performance and capacity for wireless WISP outdoor application scenarios. In outdoor enviroment, the CPE use highly directional antennas to connect to the Basestation from distances that can span several kilometers. the CPE can't sense each other, they become "hidden nodes" and cannot coordinate access to the wireless channel. Thus the Basestation experiences frequent collisions from stations transmitting simultaneously. As the network scales, these collisions build up exponentially, increasing latency and lowering throughput. With TD-MAX, it coordinate all the data transmission and allocates time to active clients to provide greater noise immunity performance when compared to the conventional 802.11 CSMA/CA (Carrier Sense Multiple Access / Collision Avoidance) protocol. 10/20/30/40MHz Channel Bandwidth for better throughput O4 apply special optimization in software for register parameter to deliver 10/20/30/40MHz channel bandwidth option. It provides extra 10MHz and 30MHz channel bandwidth option to consumize according to applycation scenarios. When you choose 30MHz channel bandwidth option, it can increase throughput for noisy environments. When you choose 10MHz channel bandwidth option, it can increase the number of available, non-overlapping channels, so networks can scale better. Channel shift to avoid interferrence O4 provide Channel Shift feature to offset the central frequency 5MHz upper. It can avoid interference from nearby AP and deliver higher throughput.

Kao na slikama Lepo očuvano 1-10 Mnogi i danas smatraju da je „Poletarac“ bio nešto najbolje što se ikada izdavalo za decu na prostorima bivše Jugoslavije. Časopis „Poletarac“ izlazio je u Beogradu, od juna 1973. do juna 1975. godine. Izdavač ovog časopisa bio je Atelje za izdavačku delatnost novinsko-izdavačkog preduzeća „Borba“. Glavni i odgovorni urednik časopisa bio je književnik Dušan Radović. Članovi redakcije časopisa bili su Dragan Lukić, Milovan Danojlić, Dobrica Erić, Ljubivoje Ršumović, Radoslav Zečević i Dušan Petričić. Ukupno je izašlo 19 brojeva – oko 1.600 stranica u velikom formatu. Komplimenti iz Evrope Bilo nam je žao dece, naljutili smo se i napravili „Poletarac“. On je toliko drugačiji od svega što se kod nas radilo za decu!“ objasnio je Dušan Radović nastanak ovog dečjeg časopisa. Tačnije, njegov povratak. „Poletarac“ je, zapravo, bio prvi posleratni dečji časopis, ali nije imao sreće, jer se ugasio 1969. godine. „U međuvremenu, u Srbiji su se pojavili neki listovi, koji ni izbliza ne mogu da zadovolje ni potrebe dece, niti da na dobar način reprezentuju književnost koja postoji. Na društvenu inicijativu, „Poletarac“ je obnovljen, s ambicijama da bude bolji i da okupi oko sebe najvrednije saradnike iz cele zemlje. I mi smo napravili list na mnogo strana, s najeminentnijim saradnicima. Dobili smo mnogo komplimenata, ne samo u zemlji, nego i u inostranstvu, jer, po rečima nekih obaveštenih stranaca, takav časopis u Evropi ne postoji. Međutim, trebaće još mnogo vremena i novaca, da se kod nas razbiju neke predrasude i otpori. Kod nas još uvek najveći tiraž imaju loše stvari,“ kazao je Radović. Poletarac Dusko RadovicTim snova Poletarac je u svojoj redakciji okupio pisce i pesnike za decu kojima ni danas nema premca, ali su na njegovim stranama gostovali i mnogi drugi velikani (dečje) književnosti – Jovan Jovanović Zmaj, Petar Kočić, Ivo Andrić, Desanka Maksimović. Bio je primer vrhunskog dizajna dečjeg časopisa, do danas neprevaziđenog u Srbiji . Pored ilustratora i karikaturiste Dušana Petričića, koji je listu dao vizuelni identitet, mnogi poznati slikari i ilustratori učestvovali su u Radovićevom kreiranju dečjeg časopisa – Miodrag Mića Popović, Ljubica Cuca Sokić, Rastko Ćirić, Predrag Koraksić. Nerazumevanje od prvog broja Međutim, od prvog dana bilo je mnogo onih koji nisu verovali u njega. U „Borbi“, koja ga je izdavala, od prvog broja su hteli da ga ukinu. Kao glavni urednik, Radović je dobio sobicu u koju je mogao da stane neveliki pisaći sto, a svoje vrhunske saradnike morao je da prima, praktično – u hodniku. „Istovremeno, na prvom i drugom spratu baškarili su se razni direktori, urednici, pomoćnici, savetnici i njihove sekretarice, u velikim kabinetima sa kožnim vratima, kožnim foteljama, kožnim trosedima i kožnim agendama. Na pitanje zašto Radoviću ne ustupi svoj kabinet, jedan od njih je iskreno odgovorio: Iz ove kože se ne može!“ pisao je Milovan Vitezović. Poletarac Dusko RadovicList za gospodsku decu Iz Jugoslavije su na račun „Poletarca“ stizale pokude – da je „list za gospodsku decu“, da objavljuje „rđave pesme“… Poletarac nije naišao na prijem i odjek koji su očekivali njegovi stvaraoci, pisci i likovni umetnici. Veliki format, modernost, koncept – sve to je, čini se, bilo suviše slobodno i nerazumljivo za to vreme. Radović je govorio o otporu na koji je „Poletarac“ nailazio u školama, o korumpiranom tržištu dečje štampe, o izdavačima koji spretno podmićuju nastavnike, svoje buduće akvizitere, kako bi učenicima „propisali“ čitanje njihovih listova. „Neki urednici su u stanju da neprestano jadikuju u kancelarijama uticajnih ljudi, da se rastrče po ustanovama kad zateba. Ja nisam bio za to spreman. Nisam imao ni vremena. Lako je ovima o kojima govorim – oni prave listove tako što slažu pričicu na pesmicu, pesmicu na pričicu, bez reda i smisla, dodaju neku vinjeticu i to je njihovo uređivanje. Ceo njihov godišnji posao se može obaviti za nedelju dana. Pristajem da sve listove koji se tako uređuju, tako uređujem sam i besplatno. Letnje pesmice u leto, prolećne u proleće, zimske u zimu, i eto formule. Zašto se naprezati, zašto izmišljati, zašto okupljati maštovite crtače, pisce, naručivati rešenja, izume, zašto tragati za novim i neobičnim, kad uspeva staro i obično?“ Poletarac Dusko RadovicIspuštena prilika Radović je zaključio da je pravljenje tog lista bio jedan pretenciozan poduhvat. Nije bilo društvenih uslova da se tako nešto oceni, a onda prihvati i podrži. „Poletarac je morao biti ugašen, jer nije bio registrovana vrednost, ovde gde ima mnogo lažnog obrazovanja i lažnog ukusa i gde se ljudi razumeju samo u ono što je javno priznato i potvrđeno,“ rekao je Radović jednom. „Mi smo pokušali da budemo strogi i odgovorni. Birali smo, odbijali i vraćali rukopise i ilustracije, borili se, koliko smo mogli, da zaista stvorimo list za „gospodsku decu“. Međutim, pobedila je duhovna sirotinja među piscima i prosvetnim radnicima. Opet su bili u pravu oni kojih ima više. Oni koje bi ugrozilo zavođenje odgovornosti i morala. Da smo imali prave podrške, to bi već bila debela biblioteka reprezentativnih književnih i likovnih priloga. Iz toga je, dalje, moglo da se „hrani“ mnogo budućih udžbenika i priručnika.To je bila velika, ali ispuštena prilika,“ govorio je Duško Radović o svom „Poletarcu“. Poletarac Dusko RadovicOdlazak u podrume bibioteka Poletarac je pred svoj odlazak u podrume bibliotka počeo da stiče evropsku i svetsku slavu. Francuzi su nameravali da ga prave u Francuskoj, i Dušan Petričić, njegov ilustrator, bio je zamoljen da izradi naslovnu stranu francuske verzije. Predosećajući skori kraj časopisa, Dušan Radovć je u broju za maj-jun 1975., na strani 2, predložio da „Poletarac“ više ne bude mesečni časopis, već knjiga koja bi izlazila svakog godišnjeg doba, u ritmu prirode – na proleće, leto, jesen, zimu. Taj broj bio je i poslednji. Istoimena serija Ipak, nekoliko godina nakon gašenja časopisa, 1979. – „Televizija Beograd“ počela je sa snimanjem istoimene serije, napravljene po časopisu, a scenarista i režiser televizijskog „Poletarca“ bio je Timoti DŽon Bajford. „Imao sam priliku da čujem njegovo mišljenje o mojoj adaptaciji. Kad je pročitao scenario, bio je očajan – rekao da nema veze sa njegovom časopisom i da ne želi da bude asociran sa televizijskom serijom. Međutim, više od godina dana kasnije, kad sam ga slučajno sreo posle početka emitovanja serije, pružio mi je ruku i iskreno čestitao, sa rečima: Očigledno ne umem da procenim scenarija!“ ispričao je jednom prilikom Bajford. Poletarac Dusko RadovicKako do “Poletarca” Dvanaest godina nakon prinudnog prizemljenja „Poletarca“, izdavačko preduzeće „Rad“ objavilo je izbor najboljih književnih i likovnih, odnosno zabavnih i poučnih priloga, u četiri knjige naslovljene onako kako je zamišljao Duško Radović. Ni njih više nema na policama knjižara. Roditelji koji nisu imali zadovoljstvo da u detinjstvu imaju ove vredne knjige, i da ih do danas sačuvaju za svoju decu, mogu ih, uz malo sreće, ponekad pronaći u antikvarnicama i na aukcijskim sajtovima. Ostali, ipak, mogu zaviriti među korice četiri knjige „Poletarca“ i prelistavati ih u elektronskoj verziji, na sajtu Srpske dečje digitalne biblioteke. Priredila: Jovana Papan
