Gentlemen, any idea what device can make UART over 2.4Ghz, half duplex? So i could put several units on the same channel.

@adamaero Cool, thank you. That was one of my candidates. Have you worked with it? If I have 10-20 devices, is it the same as having them on a half-duplex RS485?

I don't know

Thank you anyway

@adamaero Haven't read it for years, but EE Times used to be the trade mag that focussed more on business and less on technical points.

In my area there are sites like Light Reading that also give lots of business gossip.

@ThePhoton Contents of a typical free industry journal (aka industry rag) :

@NickAlexeev, sure. But in most of them the "industry news" was just reprinting a press release about how Jim Jones was promoted to executive sales manager for the Northwester Region. Where in EE Time there was at least a bit of actual analysis about M&A and business strategy in different markets, etc.

You would read Design News for decent articles (later to be remade into app notes at the authors' companies) on circuit designs, but read EE Times to know who got bought or who is closing a product line that lost out to its competition.
