The Ups And Downs And Ins And Out Of Spread Spectrum

I've started writing a series of posts about the technologies used in alarm systems, and how the spec sheets match up to reality.

I thought I'd start with frequency hopping spread spectrum which is used in some modern wireless alarm

I'm going to cover rolling codes and encryption in later posts.

I have a blog, some of which is about alarm security and reverse engineering:

And an article mentions drawbacks for FHSS, then mentions a sh1tty make and Texecom.

 

Ooops.

Sorry - I'll stop posting links. I think it needs to be more explicit in the rules - most other forums enforce it in the forum code to avoid issues.

Ooops.

Sorry - I don't understand. They both use the chip, as do several others. I could have mentioned Pyronix with the Si4432 or Cooper stuff with 3 different front ends in it, or any other. I'm not commenting on them using FHSS, just how you can push the chips harder if you aren't building a product.

The link seems pretty relevant and I can't see flocks of members leaving TSI to go and read a one way blog instead if that is the worry?

 

Enjoyed reading it - thanks CG.  I am looking forward to the one on encryption.
