RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Hi.. - RF Cafe Forums
RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media
platforms dominating public commenting venues. RF Cafe Forums began sometime around
August of 2003 and was quite well-attended for many years. By 2010, Facebook and
Twitter were overwhelmingly dominating online personal interaction, and RF Cafe
Forums activity dropped off precipitously. If the folks at
phpBB would release a version with integrated
sign-in from the major social media platforms, I would resurrect the RF Cafe Forums,
but until then it is probably not worth the effort. Regardless, there are still
lots of great posts in the archive that ware worth looking at.
Below are the old forum threads, including responses to the original posts.

That seems a good plan. Depending on your specialization background,
you could either look in detail at the rf side of the problem, or look
more closely at the man/machine interface area.
The first one has
many solutions already commercially available, so there is no point
in re-inventing the wheel. There are many low-cost products that employ
frequency hopping 2.45GHz technology, and this is well established.
Emerging techniques using the 60GHz band are entering commercial availability
but they are currently rather expensive and more suitable for high speed
I have not encountered the term mechatronics before, but it
sounds like the man/machine interface would be more your line.
