Hello I would like to study deeply about wireless technology, my goal is to understand theory and practice about making my own electronic transmitter and receiver from electrons up
Can you recommend books on subject ?
Thanks.

What kind of wireless?
- Infra Red
- Bluetooth
- RFID
- WiFi
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
The best way to start would be with RF, so rather RF.Originally Posted by MartinR
"from electrons up" is a pretty tall order. If you want to create wireless transmitters and receivers yourself at a component level, it's unlikely you'll find a single book that will cover this.
You would be required to understand and master many different aspects of electronics theory. First there are the basics (Ohm's Law and circuit analysis), DC and AC characteristics (which build on advanced mathematics), modulation, impedance matching, antenna theory, and so much more. And when you start getting into and beyond the MHz range, you need to learn the additional characteristics of RF. And the equipment required to develop and test such circuits is extremely costly and also requires training.
Based on this post, and your previous desire to know the lowest-level details of programmable logic, you should seriously consider enrolling in an electrical engineering curriculum, if possible. (Actually, an electrical engineering technology ("EET") program might be even better - this is less about the science of electronics and more about practical applications and hands-on training.)
An undergraduate education is the most practical and realistic way to learn about low level electronics and associated theories. However, this will not teach you everything - you'd most likely learn the required maths, basic electronics theory, and only touch on more advanced engineering topics. It's typical to select a single avenue to focus on for post-graduate studies, though with dedication, you can really get into various aspects.
All of this would probably lead to a job in the field, giving you access to expensive equipment that you don't need to invest in yourself. (My senior project was way advanced, and only possible because I had access to a $10,000 piece of equipment at work.)
If all this seems too much for you, consider moderating your ambitions. Maybe start at a higher level. For instance, purchase a wireless transmitter kit. This gives you all the components you need, and you assemble the circuit yourself (I once had an FM transmitter kit that was a lot of fun to play with.) You can also find books on the overall wireless approach (I do not have any to recommend). But desiging such circuits yourself from scratch is a whole other level of complexity.

What can this strange device be?
When I touch it, it gives forth a sound
It's got wires that vibrate and give music
What can this thing be that I found?
@Matticus, thanks for your answer I absolutely agree. I understand higher order math (calulus, diff. equation, lineral algebra etc), circuit theory, plus various of different aspects. As you correctly pointed out I asked before about low level programming and comp architecture, thats because I want to know stuff from scratch. Actually I am a student of mechatronics, and the problem is that we learn certain things only superficially. That is in case of comp arch. and that's in case of wireless technology. As example - in case of wireless tech. we learn and use ready to use modules and program them. I myself want to go a little bit deeper and study this things from electrons up, as I said in first post . Hope you understand
What kind of equipment you had in mind ?Oscilloscopes ?And the equipment required to develop and test such circuits is extremely costly
PS: @Elkvis - thanks, although I've already seen it.
Thanks.

For commercial applications, most definitely, but for simple home-brew projects, an oscilloscope, signal generator, and spectrum analyzer are all you need, and can be gotten pretty cheap on craigslist and eBay. Operating these devices is pretty straightforward as well. There are plenty of video tutorials on youtube.
MartinR, another book you might consider is the ARRL Handbook. It's primarily aimed at amateur radio operators, but it is packed with tons of information.

Don't forget a DVM, power supplies, cables, soldering irons, prototype boards (which are difficult to homebrew, since material and dimension of traces greatly affect line impedance) and components. (Though individual components may be cheap, for development, you'd want a range of resistors and capacitors at the very least, and kits can add up.) Also scope probes - high frequency scope probes are a lot more costly than the cheap versions that are better for slower pulses and waveforms. There's also dozens of "little things" that also add to the cost (solder, flux, wick, etc).
All told, I'd say someone would be extremely lucky to get an entire lab setup (including the ability to handle RF) for under $2000.
I've gotten some good equipment online in the past, but have never seen a scope go for less than $500, though admittedly I haven't looked in years.
I knew I recognized it. I have that very book here at home.
I took a shot of it for prosperity (along with my nerdy programming pint glass).
Hehe nice pic but honesty, the pint glass stole the show
Backing to the subject, from everything you said I guess you played with RF circuits and failed, am I right ? Did you find that book usefull ? What was the hardest part to do in your case ?
PS: Elkvis, thanks for ARRL Handbook, it seems to be very usefull book
$2000 is a very doable number. Even if it takes a few months to a year to get all set up, it's not too bad.
I've gotten them for free. You just need to know where to look.

No actually, I spent a few years as an RF tech - digital and programming was just a hobby then. When the one and only digital engineering position opened at my job, it was offered to me and I took it. I have more of a knack for digital than analog.
But yes, I did find that book very useful at the time.
Any suggestions on where to look?
I got an old analog scope from a colleague years back, but I've been spoiled and would prefer a digital scope.

You can get USB scopes that interface with a computer for pretty cheap these days.

I have relative who has gotten tons of that equipment for free, both from ham fests, and from things his work was going to throw away. Some of it went to a local vocational school, a good bit of it needs some repair.Any suggestions on where to look?

My favorite was a MicroLogix 1000 that I got to play with as a kid. It turned out to be such a great pranking machine that my mom ended up taking it away, but really who doesn't want the bathroom door to trigger Metallica?

I think getting a firm understanding of the whole stack from electrons all the way up to application protocols is a bit of a tall order. Even walking around the halls of Qualcomm I never encountered anyone who understood it top to bottom like that.
If you like antennas, focus on antennas. That's pretty much all you're going to have time for...
