    JIMX: Na LTE jak pises. Na 5G to není potřeba. Pokud nemáš ani jedno, data spadnou.

    A není VoLTE taky dobrý k tomu, aby mi nespadl internet, když telefonuju? ... nebo si to s něčím pletu?

    ARIAEL: Zároveň nemít VoLTE a zaroven nemít 5G je pro mě nepoužitelné. Běžně mi lidé volají a abych jim pomohl, musím mít data. YMMV.

    LAUNCHER: No Volte moc velkej zazrak neni, protoze tam kde neni dost signal pro volani a prepinalo by se na volte uz davno neni ani LTE. A mimo mesta je lte jenom sen...
    VoWIFI uz je hodne pouzitelny, ale zase malokdo to ma. Protoze naopak kdyz jsi uvnitr budou kde je obvykle nahovno signal tak zase obvykle mas wifi...
    A 5G? Nejak si nejsem jisty kolik ze gigabitu za vterinu potrebuju pri prochazce v lese nebo na Karlovo moste...
    Ale vzhledem k tomu ze za mesic celkove spotrebuju nejakych 60-70 GB, tak si myslim ze to nejak preziju i bez tezkyho traumatu :)

    3. USB Power Delivery Versions
    USB PD technology has come a long way since its inception. Let’s look at some of its different versions.

    1. USB PD 1.0
    USB Power Delivery 1.0 came out in 2012 and allowed power delivery up to 100W over one USB cable. USB PD 1.0 included specifications for compliant cables and connectors. It came in traditional USB connector shapes with minor differences to the internal wiring.

    PD-compliant cables were compatible with most USB ports while standard USB cables needed to be connected to appropriate ports.

    2. USB PD 2.0
    Released in 2014, USB PD 2.0 introduced related power rules from USB PD 2.0 rev 1.2 and required the use of USB Type C connectors. The power rules need multiple normative voltages and current, enabling smoother power delivery and usage among devices.

    3. USB PD 3.0
    USB PD 3.0 was released in 2015. It allows the advanced use of Type C power capabilities and functionalities. One of the most noteworthy features of USB PD 3.0 is role swapping.

    Consider this example to understand role swapping. A laptop that charges an external battery via USB is likely to get completely drained. Earlier, the only way to get the power back from the external battery was to remove and reconnect the cable. This worked only if the internal battery was connected through Type A (supplying power) and Type B (receiving power) ports.

    Charge Desktop Charger

    USB Type C charger eliminates this problem through role swapping. As long as the power conditions are met, the computer and the external battery can quickly swap roles. The laptop can become the power consumer instead of the provider. The battery would charge the other way. This would happen without the need for reversing the cable or using multiple ports.

    Role swapping works not only with charging, but also with data communication. Further, data communication can take place without interruption as the power role changes. Simply put, data can continue to flow in a single direction even as the power direction changes.

    DARUMA: Kupovat si telefon od tvurce platformy taky neni koser :)

    Lidi si najdou duvody vzdy, principy ve smes nemaji. Tady pravdepodobne nechteji mizerny telefon za cenu halo produktu a tohle je dobry duvod jako kazdy jiny.

    Dragon jenom dava rozum, tam kde neni :)

    DARUMA: Volte neresim, na pixel5 se dal nakonec rozbehat taky, ale u toho 5G je princip ten, ze operatori s 5G senzaci proste lzou a lidi na to nabihaj jak vosy na med (hlavne starsi lide, kteri se bali, ze kdyz jim na vesnicich ted povypinali 3G, tak si uz nezavolaj) a a to mi fakt nelibi. Princip je IMHO ten, ze vyrobci a servis provideri lzou, ne to, ze ma nejakej mobil coutry restrictions nektere softwarove vybavy.

    DRAGON: díky, prostuduji. jen je otázka, zda vinit notebook, který je z roku 2020, kdy se PD imho teprve ladilo.

    DRAGON: Jde o princip ne? Když si kupuješ telefon co by měl umět 5g a Volte ale tobě to nefunguje tak to prostě není košér.

    MCKIDNEY: nemluvim o Volte, mluvim o 5G. Tahle technologie poradne nefunguje ani v Korei nebo USA, natoz v Cechach. Opakuju, je to jen fake mrt*a, ktera z drtive vetsiny lita po frekvencich 4G/LTE.
    Takze ne, nepohybujes se u 5G hotspotu, protoze tu realne zadny nejsou.
