  • 5G iPhone launch unlikely to be 'massive event,' AT&T executive says

    rbnetengrrbnetengr
    I think that it doesn’t make sense to offer mm wave  5G in an iPhone. Mm waves require line of sight for communication, so you need to not only have your device out in the open, but also a clear shot to a mm wave antenna. At mm wavelengths, the radio waves act light light waves. So, if your device is in a ‘shadow’ caused by something blocking your device’s line of sight, it will either not work at all, or work poorly.  Verizon is apparently banking on it to claim the highest 5G speeds, but what good is it if it’s only available in 2% of their coverage footprint?  

    They also chose to deploy it in stadiums, where high density population gathers for events. So, what good is it to have 5G serving the football stadium that you visit...never?

    I thought that the purpose for mm wave 5G was to replace wired internet (DSL/Cable) with a fixed, line of sight system. Thus, gigabit Ethernet speeds without needing to wait for AT&T, Google, etc to rip up the neighborhood and streets to trench fiber.

    Apple Watch Ultra on a man's wrist, showing the model number

    Why does this dude have is watch upside down on his left wrist.  Makes it hard for the right hand to use the controls.

    I use my watch the same way.  With the crown and button facing my wrist, I accidentally engage the buttons when I am wearing gloves and working out in the gym.  Having the controls on the other side prevents this from happening.

    I am right handed and have no trouble using the controls in this way.  It took a few times to get used to it, and then it became completely normal for me.
