In 802.11p (DSRC), what is the maximum number of connected devices per square kilometer?

Question

I was reading about C-V2X and it has the capacity of 1 million connected devices per square kilometer. I wonder what is the corresponding number for DSRC (dedicated short range communication).

I googled it for a while but was not able to find any explicit information about that. Kindly let me know if there is any recommended platform to ask this question if stackoverflow is not the right place.

Thanks!

Answer 1

You are using two separate routing contexts. This means that nested router that Login is rendering is handling its nested Switch and Route components in isolation from the outer router.

Remove all nested routers, you need only one router per app to provide a routing context, and as you have found out, you want all your routing components to use the same routing context.

Within the Switch component, route path order and specificity matters, order the routes in descending order of path specificity, i.e. from the more specific paths to less specific paths. When the paths are ordered correctly there is nearly no need for the exact prop. Now all paths can match as path prefixes for any nested routes that may be rendered.

You will want to not exactly match on the "/" path that Login is rendered on so the nested Switch and routes and be properly matched. It seems there is a circular dependency between Login rendering the route for DataConfirmation and DataConfirmation rendering the route for Login, so I'll just assume at this point one of these is a typo and that your routing is generally structured as you like and is working.

Login

<div>
  <Switch>
    <Route path="/DataConfirmation">
      <DataConfirmation/>
    </Route>
  </Switch>
  <Link to="/DataConfirmation">
    <Button type="submit">
      Login
    </Button>
  </Link>
</div>

DataConfirmation

<div>
  <Switch>
    <Route path="/HomeSearch">
      <HomeSearch/>
    </Route>
    <Route path="/">
      <Login/>
    </Route>
  </Switch>
  <Link to="/">
    <Button type="submit">
      Change phone number
    </Button>
  </Link>
  <Link to="/HomeSearch">
    <Button type="submit">
      verify
    </Button>
  </Link>
</div>
