Paari päeva pärast minnakse kooli, eks siis ole näha, palju, vana hea, TPI-kooli õppurid tundides tarkust tuubivad või palju tuupimise asemel Tele2-e HSPA+ võrgus, hommikust hommikuni, kraami alla tirivad.

Igatahes Olümpiamängude ajal Tele2 interneti kiirus ei teinud teist nägugi, et kõik sporti vaatasid.

tahanteada, sul on nüüd oma teema ja paluks TELE2 mõõtmistulemustest postitada vaid sinna ja see teema puhtana hoida

Täna hommikul oli taas signaal punane ja ühendus sisuliselt puudu.
Ülekuumenemise võib vist välistada. Ruuter tiksus ilma igasuguste probleemideta 44-45 C peal päev otsa. Testi mõttes andsin Steami allalaadimistega natuke koormust ka. Temp ei tõusnud, kõik töötas. Täna hommikul oli ruuteri põhjatemperatuur kukkunud 39-40 peale ja probleeme rohkem kui küll.

Speedtest eile õhtust:

Speedtest täna hommikust: Oli veel hullemaidki tulemusi, aga ei jõundud ära oodata, et test lõpetaks.

Panen siia otsa ka hommikuse pingi www.neti.ee suunal.

Teemaalgataja võiks teema pealkirja ära muuta, kuna mina räägin DC-HSPA+ Levioaasidest, mitte leviooasidest, mille alla võib liigitada näiteks 28,8 megase kiiruse toega HSPA+ levialad.

Tegu siis levialadega, kus MIMO-toega ( Multi In - Multi Out) HSPA+ modem saavutab nii 20-21 megabitise kiiruse võrrelduna siis tavalise, ilma MIMO-toeta HSPA+ modemiga, mille kiirus on nii 15-16 megabitti.
----------------------
Aga seda on muidu märgata küll, et on oluliselt suurenenud MIMO-toega HSPA+ modemite tootmine.

Edit: Nüüd siis väike näide kah, kus HSPA+ 21,6 mega kiirusega modemisse on MIMO-tugi sisse ehitatud ja seetõttu suudab see modem töötada ka 28,8 megase modemina. Aga seda siis juhul, kui ISP-l on olemas MIMO-toega HSPA+ võrk.

tegelikult peab olema ju just ainult suvalised leviooasid, sest sa oinapealuu ei saa endiselt aru, et ka 1200 bps 1985 aasta modem saab olla OAAS, kui ta korrektselt töötab ja liin võimaldab madala latentsusega ühendust.

hoian antud teemal ja oaasil silma peal

ega siis netitestimine ei võta kusagilt infot ära, vastupidi, pidev testimine koormab asjata meediume. neti osas võiks teha eraldi saate, vahelevõtja, kes siis käiks tahanteada moodi mööda eestit ja kraaksuks, et siin polegi +++!

Kuna peagi on käes aasta 2013, siis vaidleks natuke, et kas aastal 2013 toimub see, mida USA ISP-d üksteise võidu lubavad. Et alustavad tööd maailma esimesed True-4G (LTE-Advanced) võrgud ning LTE-Advanced võrgud võimaldavad rajada ka kuni 1GB kiiruseid püsiühendusi.

Ja siit teine vaidluspunkt, et kui Verizon, AT&T, T-Mobile oma kava ellu viivad, kas siis Eesti ISP-d suudavad ka sammu pidada, pannes ka Eestis aastal 2013 tööle samamoodi True-4G (LTE-Advanced).
------------------------------
Nii, et edukat vaidlust ja ärge üksteisel nina veriseks lööge.

Mina ennustan, et USA-s viiakse LTE-Advanced arenguplaan ellu ja Eesti ISP-d peidavad pea liiva alla, et nemad pole jällegi millestki midagi kuulnud ja ei viitsi arenguga kaasas käia.

Väike videopilt kah, kus Ericssoni mehed demonstreerivad, et LTE-Advancedi korral on võimalik 1GB ühendus ka aeglase liikumise korral.

---------------------------
LTE-Advanced tehnoloogia on tänaseks päevaks olemas kõigil kolmel Telekommunikatsiooni-hiiglasel, Ericssonil, Huaweil ja NSN-il.
LTE-Advanced kiiruserekord praegu on NSN-i käes ja see on 1,4GB.
Videopilt kah siis selle NSN-i rekondipüstitusest:

Liitsin teemad kokku. No ei ole vaja eraldi teemasid.

[RCC]

tubli, jään ootama nüüd võimalust endalegi soetada leviooaasi, avatud pordid, mahupiiranguta.

[Dijital]

tahanteada, kas kuskil on su levioaaside kaarti ka võimalik vaadata? Siis teaks, kuhu vaja uus kodu soetada.

vana_urr: Tegin Sinu tarbeks ühe uhke testi 7,2 megase HSPA modemiga E220.
Võta ja vaata ja näita, kuskohas Sa näed mingeid imepärast, müütilist kiirusekukkumist 10-100x.

Kiirusekõikumine on olemas, see on näha Huawei tarkvara Download graafikust ja kõigub enamjaolt 4-6,5 megabiti vahel, mõni üksik kukkumine on ka 3 mega peale.
Aga nüüd siis mõõtetulemus. Testi tegi Huwei E220 modem ja mõõtis Dumeter.

PS: Sellega olen kindlasti päri, et mobiilinterneti korral kiirused kõiguvad. Kuid nad saavad ikkagi kõikuda a 3-4x, mitte aga pole kiiruse kukkumine kümneid või sadu kordi.
Selliste imepäraste kukkumiste korral on igatahes ISP võrggus midagi kõvasti segi ja siis võtavadki Lp. tehnikud jalad laua alt välja ja lähevad tõõmsalt viga otsima, kuna nad saavad palka töötegemise, mitte töölkäimise eest.
