In the asteroid scene, why were some of thje ships running with their sheilds down? I see no logical reason.

Were they switched off or lowered by asteroids? After a few hits the shields of the Falcon was also down.

To what are you referring?

They had their shields down because Vader ordered the SDs to, in order to make hyperwave transmissions for face-to-face hologram communications between ships.

Hyperwave transmissions when they were quite close to each other?

No Shields are down to Communcate, Any Long Range Communcation sans Blink code does work with shields up, Suppodly it wonk's up trasimissions to bad

I did not know this. So, your saying that to use a holographic comm system, they have to drop their sheilds? That makes sense.

Yes.

It's because hyperwaves transmisions, which are required for holographic communication, are blocked by shields.

I higly doubt this. Holographic communication is simply data exchange.
Why to lower your shield facing with an ion canon or asteroids when you have normal communication methods? And I also highly doubt that an AT-AT has equipment for hyperwave transmissions. And we saw holographic communication between an AT-AT and the Executor. EDIT: Besides the AT-AT was under a theatre shield at that time.

Forgive me for my (unusual) ignorance of the topic, but where does it say that they had their shields down?

Robert Trader: I do not know. I asked nearly the same (Were they switched off?).

There is no reason for the ISDs to run with shields down. However the typical excuses are they were down for holonet communications and so their sensors would be more effective. Which in my opinion are not only lame excuses to claim the shields were down, but also stupid and unnecessary reasons to shut down the shields.

Hint to the brillant, If you'r shields let communcation singals through, They let Energy weapons on that frequence in as well


Galaxy in his normal ignorance shall ignore all EU sitautions inculding Dark Force Rising, Heir to the Empire, Dark Apprentice and others where rasing shields cuts communcation(Unless the Communcations equipment extends beyond the shield, only viable in small craft)

IIRC didn't one of the captains (the one that lost Han when he moved to 'attack the SD') specifically say 'shields up'! Can't remember if this was inside the asteroid field its self, but it does clearly show that the shields were down (intentionally) for some reason.

Did that make any sense?

They raise shields when they

1. 1 Attack Hoth
   2 Are in the asteroid field.
   3 The Falcon swings around and makes its desperate run at the Avenger to hide behind the bridge.

They lower shields TEMPORARILY when they have the holo-conference with Vader and lower them again when they leave the asteroid field. No need to keep the shields up once you're out of danger. Yes, they were out of the asteroids when Han runs at the Avenger. The scene before it, 3PO says, "Oh good, were finally comming out of the asteroids" or something to that effect.

The TESB asteroid scene is most excellently covered on Lord Poe's "shield" page:

You'll note that FTL comms are noted to be blocked in HttE (subspace) and both AotC:ICs and Dark Empire (hyperwave). Additionally, standard comms would have interfered with standard sensors and probe/recon communications, so standard comm traffic was handled mostly through shuttles (as noted in GG3) - and the holocomm transmission occured DURING the search for the Falcon (meaning that sensor scans would be of tremendous importance.)

But its largely irrelevant. The SWE (as noted on Wayne's site) clearly indicates that the transmission that occured in the asteroid field WAS a holonet transmission - which falls under the hyperwave definition.)

Thus, shields were down. Simple as that.

Short-range communications are not blocked by shields.

However Vader was administering a major taskforce across many AUs and possibly light-years. Not to mention they had to punch through any interference from the asteroids. So he called a holoconference.

I guess that means that they let visible frequency weapons through as well, since we can see them.

Eh? He chose the method that would require the highest bandwidth to punch through interference? Morse code is still used today because it requires lower bandwidth to convey information than other methods, and so has the greatest resistence to interference. Transmitting 3-D (holographic) information is far more bandwidth intensive.

AOTC:ICS states that hyperwave transmissions cannot be sent thru shields. AOTC:ICS allso states that holonet is based on hyperwave transmissions, conclusion, since the ISDs were using holonet at that one scene in TESB and holonet transmissions are impossible when shields are up --> Shields were down.

If I remember well, he ordered all available ship to search the asteroid field far before that conference. And it is unsure whether it was a real conference (all captains can see all the others) all just status reporting (Vader can see all the others, but the captains can only see Vader).

However my main point was that a holographic communication does not need hyperwave transmission. We saw a short range holographic communication through a theatre shield on Hoth.

So, if that holo conference was not a long range one it would not require the lowering the shields. The definitely long range holocommunication (between Vader and the emperor) required the Executor to leave the asteroid field.

When the asteroid rammed the bridge tower of the SD. How else could it have gotten through?

Also remember that the shield on Hoth was not a full planetary model.

It was designed to prevent direct bombardment of the rebel base, not to protect the entire planet.

The Imp's could have (and most likely did) set up a holo re-transmiter at the base camp were they dropped the walkers. This would have allowed them to send a holo signal around the shields.

That's true cuz how else would the AT-ATs got on the planet.

Why do you all think shields need to glow?
