wireless design book

[[email protected]]

Hi,

I need to build a wireless system at the amateur frequency band for a
school project. The base station needs to send a beacon signal to
remote devices and the remote devices reply with their data.

Does anyone have any recommendation on books that explain important
aspects of wireless design, such as data encoding or how to retrieve
the beacon signal, etc.

Many thanks,
feilip

Have you got an amateur radio license? You could get into serious
trouble if you transmit without one.

first, take note of what Leon said, and try to use the license free
bands

You don't say what range of how much data you need to send, which is
important.
check out ARRL publications,

Not all transmitter use requires a license, ham or otherwise. You should
quote the post to which you are referring so everyone will know the context
of your post.

Thanks for your replies!!

It is just for a school project and it is running at 433.92MHz. It
needs to transfer 100 bytes of data. So I guess it is a trade off
between data rate and distance...

Unless you really need to build the wireless system, it'll be much
easier to use a pre-built transmitter/receiver pair, plus some Holtek
encoder/decoder chips. You can get these from digikey, futurlec, mouser,
etc. You can get 4k bits per second from these things, at a station cost
of about $20.
