Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. noobian Post subject: RF transmitter and receiver selection Posted: Wed Oct 14, 2009 12:13 am Lieutenant Joined: Tue Oct 13, 2009 11:45 pm Posts: 1 Hi there, First of all I applogize if I've posted this in the wrong index. I'm brand new to the world of RF and I'm attempting a design project I've had in my head for a while now. I'm getting overwhelmed while trying to source/specify the correct receiver/transmitter combo for the job. This is a household application (not just a garage door opener, need range in the entire house/multi levels). Ridiculously low data rate needed. What frequency range should I be looking at? What type of modulation scheme is recommended? Are there household frequency ranges? I'm looking for an "off the shelf", ie. digikey, product that's cheap, SMALL, and user friendly. Something that would work with a small antenna or PCB antenna would be good too. Any suggestions? Or any features I should be considering and have not listed here? A friend suggested ZigBee but that can be costly. Basically I have no idea where to begin designing this RF link and would love any bits of info you have to share. Posted 11/12/2012 | ||||||
