need transeivers for system development

[T. Rooks]

Hello,

Please be gentle. This is my first time;) .

I am a retired computer/medical electronics/electromechanical device field engineer.

A friend got me interested in developing an idea he had. It involves having various separate units performing precise high speed operations in a time and security critical network.

I have developed several modules and have them working as intended in a 'hard wired' ring topology configuration. What I now need is to get them converted to wireless using as small packages as possible to get no less than 100 meters range in the outdoors. They must also have an operating temperature range of -50 to +85 C. They will spend most of the time waiting for very short transmissions and will respond with very short transmissions.

I am prepared to develop my own protocols for them to sync up and accept commands/data to and from each other as I already have a rudimentary system doing that task. However I would not mind modules that have embedded 16/32 bit processors if I can get documentation and be able to use Basic or C programming and if it can add an extra level of security with minimal time overhead.

Any and all recommendations, suggestions or ideas will be greatly appreciated and acknowledged.

Thanking all in advance for your help,

Tim

Brian,

Thank you for your quick response.

The part number you mentioned was indeed one of the reasons I came to this site to post an inquiry. Actually it was the older version of that part that had come up a time or two in my research.

It is indeed a fabulous part and if I had much deeper pockets my search could very well have ended here. In many cases there are whistles and bells all lumped together in the product that do not necessarily fit or even enhance what my design is about.

The process I am about at this time is not so much filling my shopping bag with the best available as it is with finding very good products that I can use in combination and can afford at this time. There is also the problem of new standards and methods that were heretofore unknown to me.

I am a bit curious though as to why the link you provided takes me away to another site entirely. Could you enlighten me a bit about that?

For now I am leaving my query open in hopes of gaining other inputs.

Thanks again for your response,

Tim
