#2"WIPE is suspected to be intended mainly for secret, non-broadcast message transmission for private trading clients while broadcasting financial and economic news for the public."

#3Confusingly, despite relating to encrypted messages, "DRM" in this context is "digital radio mondiale" which appears to be this: https://www.drm.org/technical-info/
Use of COFDM for digital radio in the current AM bands, part of the final AM phaseout?

#4There might be a neat way to work around these laws...
Make all the data, including the financial data public. But make sure the people you want to see the data can access it first.
Arrange the data in the air so every error recovery block is mixed with financial and non-financial data.
Send the non-financial data out of band, and ahead of time, to your paying customers.
Now when a data block starts being transmitted, the paying customers can combine the non-financial data with the transmitted block (for example with xor) and decide to extract the data they want after just some proportion of the block has been transmitted.
The public have to wait till the end of the block to decode the data, by which time the data isnt valuable anymore.

Sounds like a judge will have to decide if that's in the spirit of the law. But it's very neat, I have to agree.

#6This should be understood as high frequency stock traders fighting for turf. One shop tries to access broadcasting bands to enable higher powers, thus, more reliable transmission, by multiplexing the payload with general purpose economic news - allegedly. Another HFT shop is trying to preempt this.
The race for speed in financial markets has reached a point where no existing fiber optic or satelite based system can compete; the state of the art are short wave radio that bounce back on the ionosphere and enable intercontinental communication at the speed of light over the shortest path and with no intermediary hops. Fiber optics, for contrast, can only do about 2/3 of the speed of light and impose non-direct routes and multiple hops.

A HN comment in another thread (which I can’t find atm) states that this is no longer relevant because exchanges now allow colocation in the same buildings as the servers running the exchange, and it’s relatively inexpensive. Is that comment inaccurate?

These links are often used for executing strategies or sending information between different exchanges (a classic example being the cross-exchange arbitrage).

To put it more concrete, there are a number of very large companies that have their stock traded in many locations. Japan, London, and New York all have big stock exchanges (that is just what I know of without looking - if you told me those were the only 3 cities with global stock markets I'd call you a lier). If you see a big company in London trading for slightly less than the same company in New York then you should buy stock in London and see it in New York, but you need to be first - there are several others trying to do the same thing that have enough money to make the price even alone. (my guess is that we are talking about needing $10,000 in cash ready to pull this off for the biggest companies)
