There is a reason why every single player in the V2X space is having so many difficulties and those difficulties can be summed up with the image for this article. While what this shows looks like a good idea: vehicles up the road able to communicate with other vehicles farther down the road to give information on things like road conditions, traffic and so on; it also points to a real issue.
In a mesh networking scenario, the minute a node comes online it is available to all other nodes. Vehicles in this scenario are sending out information about itself to all other vehicles on the network.
Now imagine for a second the road is an extremely busy freeway in Los Angeles. It is easily conceivable that every single vehicle on the road for multiple hundreds of square miles would be connected up to a single massive mesh network. That means every vehicle on that network is now communicating with every other vehicle even those potentially multiple hundreds of miles away on roads that have nothing to do with each other.
Now to be fair, players in the space are working on ways to limit how far out a message is sent, but sending out a generalized broadcast is “rather difficult” (to put it mildly) to control how far you send it. It’s either limited or it isn’t. If it is limited, how do you limit how far information is sent (in terms of radius) on a “general broadcast.”
This is why we keep saying that basically everyone in this space is coming at the problem in almost entirely the wrong way. Spider V2X is being built on a completely different protocol stack that allows for easily controlling how far out a signal about a given vehicle is sent or received. From there it’s a simple matter of the communication protocol to allow for the transmission of vehicle data to other vehicles, and then receiving the same information from other vehicles and passing it off to the vehicle’s AI.
This is why we are so far ahead of every other player in this space.
