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.

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

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.
