Welcome to /c/tumblr, a place for all your tumblr screenshots and news.

Our Rules:

  1. Keep it civil. We're all people here. Be respectful to one another.

  2. No sexism, racism, homophobia, transphobia or any other flavor of bigotry. I should not need to explain this one.

  3. Must be tumblr related. This one is kind of a given.

  4. Try not to repost anything posted within the past month. Beyond that, go for it. Not everyone is on every site all the time.

  5. No unnecessary negativity. Just because you don't like a thing doesn't mean that you need to spend the entire comment section complaining about said thing. Just downvote and move on.

Using Wi-Fi for this seems like a really weird choice. I'd think the better per option would be something like low energy Bluetooth.

Maybe it's a bandwidth thing?

Range of BT is much shorter than WiFi also

How far behind are you pulling this thing?

[–] dream_weasel@sh.itjust.works 4 points 11 months ago

What do you mean? I sent mine on ahead yesterday.

The trailer module can still be hooked to the car physically while providing it's own power.

That completely defeats the point of using wifi. You may as well connect a cable at that point.

[–] chiliedogg@lemmy.world 1 points 11 months ago

That's kinda my point.

Not sure if satire or not...

I haven't read the patent, but I'd bet my shiniest quarter that the phrase "in one or more embodiments" (or the equivalent) shows up.

When you write a patent application, you usually try to cover as many use cases as possible. But you also can't be too vague or abstract. So you provide an "embodiment" to show how it works, typically using existing technology. Then you clarify the broad cases--so in this embodiment they use wifi, but could use other secure, high-bandwidth wireless protocols.

It's not actually. Bluetooth, especially LE, isn't made to be secure, robust, or work with any distance. You don't want to lose control of your cargo because it's raining or you went around the corner.
Nothing wrong with wifi here in particular
