Talk:Balise

Bits or Bytes?
1000 bits or 1000 bytes? Tabletop (talk) 05:22, 20 November 2008 (UTC)


 * I'm guessing bits, as 1000 bytes is a lot of data to transfer in the split second that the balise would be active, given that the telegrams need to be received three times to verify their contents, IIRC GorfGnome (talk) 13:01, 29 March 2010 (UTC)


 * Minor point, but some readers are bound to notice that (3+12+10+85) + 830 does not equal 1023 and that (3+12+10+85) + 210 does not equal 340.198.91.9.101 (Paul Niquette (talk) 17:07, 16 September 2011 (UTC)]) 17:04, 16 September 2011 (UTC)


 * Hopefully clarified with pointing to the symbol encoding step before showing the telegram structure Guidod (talk) 19:08, 16 September 2011 (UTC)

Pairs of balises
It is not correct, that a pair of balises always consist of one fixed and one switchable balise. First, it's not necessary to have a pair. Single balise groups (consisting of just one balise) are possible, too, when using ETCS (Eurobalises). Second, a balise group can be a pair and it may consist of two fixed balises also (ETCS). 29 July 2009 —Preceding unsigned comment added by 81.14.226.39 (talk) 08:09, 29 July 2009 (UTC)

Types of Balise
This article only goes into detail on the balises used by Ericsson/EBICAB ATC and derivatives (i.e. the French KVB). Does anyone have any information on the Belgian TBL system, which uses a different sort of balise? I can't find any sources about the other variants, or even articles which detail how the various systems work; I presume its some sort of radio-frequency electromagnetic induction, but I'm not sure.

Security and authentication
How does the reader on the train know that the balise is a legitimate authorized device, and not one placed by a spoofer? Or for that matter, not one that got mixed up with one intended for another location? --Wtshymanski (talk) 15:37, 23 March 2012 (UTC)
 * There is no cryptography involved.... and it's up to the train driver to check malfunctions. In a way he does that on a daily basis. Guidod (talk) 19:51, 24 March 2012 (UTC)

Cut out Eurobalise
I'd like to cut out the specifics of the Eurobalise into an extra article, just as it is common in other Wikipedias. It is actually possible to use balises without that digital encoding. Guidod (talk) 16:47, 23 February 2016 (UTC)
