Re: Choice of frequency and protocol on RF links?


900MHz will not work, that's why I wrote 433MHz.... (ISM also).
Well I do not *want* to design the stuff, but do not mind the NRE if
resulting BOM is very low... ;)

In what geographic location do you expect to operate this equipment?
Do you expect to write or to buy the baseband encoder/decoder firmware?

Unless designing this stuff is your bread and butter, I'd suggest
buying it all off the shelf. There are 900MHz and 2.4GHz solutions that
might work for you... an easy off-the-shelfer is MaxStream (but not
exactly cheap).
