Hi.. - RF Cafe Forums

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.

Hi rusty
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 LANs.
I have not encountered the term mechatronics before, but it sounds like the man/machine interface would be more your line.
