Are Oathgates an implementation of the Surge of Transportation? If so, how do they work?
And what does this have to do with Rhythm of War?

Oathgates exist in the physical and cognitive. We do not know whether you could use an Oathgate to transfer between gates in the cognitive or from a gate in the physical to another gate in the cognitive realm. We have seen them used to

  • teleport between gates in the physical realm
  • transfer between the same realm in the physical and cognitive realm

Rhythm of War has shown a qualitative difference between these applications. You can transfer dead shard plate between gates, but not into Shadesmar. Why is that? It looks like dead subspren do not transfer to the CR.

However, that makes a difference to the mechanics. It calls into question whether the transfer between gates functions through the CR. Rather, it looks like the surge of Transportation is teleportation and the source and destination happen to sometimes be in different realms.

Yes, they utilize the Surge of Transformation, per this WOB:

Questioner 1

Can you tell us about Transportation? Is it like gates from Wheel of Time

Brandon Sanderson

Oh, Elsecalling? No. But-- but yes. 

Questioner 1

*laughter* I meant, like, the whole-- Just the Surge?

Questioner 2

Does it go to the Cognitive Realm, is that all it does? 

Brandon Sanderson

It is the power by which they created the Oathgates... So, there is a little more to it than that. But yes, it's basically-- yeah.

The direct question was RAFO'd, but since RoW we can confirm that Surge Fabrials tend to be unBonded Radiant Spren.  The theory since we saw them in Shadesmar is that each one uses an Inkspren and Lightspren as the two that Grant the Surge.  We dont know how they were made but Im guessing it was Honor himself and probably around the same time as the Sibling themself since they are the heart of the gate system. 

Per this WOB, the Oathgates are specifically Spiritual Realm teleportation, distinct from any Cognitive Realm travel:

Questioner

Did humans come to Roshar through Shadesmar?

Brandon Sanderson

It is technology or magic closer to how the Oathgates work. But it was like that. It's not canon but right now that's what I have. It's not canon because there are certain things I have to work out before that can work...

By the way I'll just say to the tape recording that I haven't canonized, like for instance if they traveled to Shadesmar to get to Shinovar from Ashyn. Right now I have that not being via Shadesmar, but the mechanics of that might not work out, and I might have to default to Shadesmar. So there's certain things, you'll see, where I say, "This isn't the canon answer, it's where I have things right now."

So Urithiru might end up being a spaceship after all.

Brandon Sanderson

It's not that. Right now I have them using something closer to Oathgating, but it opens up a huge can of worms, when I'm not requiring direct-- When I'm sending through Spiritual Realm it opens up cans of worms, and I have to just make sure the mechanics on that are tight before I do it.

Shardplate has a few differences with Shardblades, (No screaming, contented in their new form, etc). But I believe the issue is that Blades revert to their native spren form in Shadesmar, but with Platespren being "Content" in their new form, I dont think they retain the ability to transform back to their original Shadesmar/animal form.

Yes. They are Fabrials, they have spren like Soulcasters attached to them and Brandon confirmed it's an implementation of the Surge of Transportation.

What was the fabrial used by Nale to completely revive Szeth at the end of Words of Radiance? That seems like an immensely powerful fabrial, and I don’t think it has been mentioned since.

Brandon Sanderson

During the last days of the heights of the Knights Radiant, they were figuring out how to replicate most Radiant abilities with fabrials. This is where... the Oathgates as a guide for that sort of thing. So you're just seeing a fabrial that can replicate what an Edgedancer does, or a Truthwatcher. There were fabrials created that could do this for all ten Surges. Okay, nine of the ten Surges. Bondsmithing is its own weird thing, as usual. So yes, it's a very valuable fabrial to have, and that is why you haven't seen much more of it because it is in the hands of the Skybreakers, and we aren't spending a lot of time with the Skybreakers. But yeah, it is a thing they have. And there are fabrials that can replicate the other eight as well. You've seen several of them in the books already.

I think they use the light you provide to form a temporary perpendicularity and activate both Oathgaths at the same time. You have two perpendicularities open now and the gate just pulls you through them through the SR. The people of Ashyn arrived on Roshar with the use of the Elsecalling, not Rosharan one but the same power, Oathgates do just that. 

However they are manifestations of two sprens, not one as other Fabrials we know. We don't even know which spren are they - they don't look like Radiant spren.

They don't know the way to do that, but iirc it was suggested in RoW that the Oathgates can be used to travel between 10 cities without the need to go to the Tower first. I think it's unlikely that you can use the Urithiru gates and travel to CS in Kholinar for example.

Can any Oathgate go to any of the 11 locations?

Brandon Sanderson (paraphrased)

As far as [the people who discovered Urithiru] are aware, the gates can only go to Urithiru.

For the same reason a dead Shardblade also doesn't make that trip - it's already there in CR. The plate and a Shardblade is just a physical manifestation of spren. A Shardblade can be dismissed and a deadeye will appear in CR, but a dead plate can't. I assume you won't be able to take any fabrial with you for the same reasons - they already are in Shadesmar.

Obviously the transfer between gates doesn't go through the CR, it goes through the SR because it's spaceless and the distance there simply doesn't matter.

The white Oathgate spren doesn't look like an Lightspren and both Oathgate spren calls the Sibling their parent. I don't think they are the Radiant spren. Coppermind:

Quote

lightspren appear human and can have features similar to different Rosharan populations, though they have metallic bronze skin, making them look like living statues.[9] They have bronze metal eyes with holes where the pupils would be.[10] Their hair is similarly metallic bronze
