RFID - Micro-controller - Switching Wireless Project

This project involves a number of steps, the general jist of it is that we're looking for some software for the tracking of items between zones using RFID. We have the RFID technology, however we don't have the hardware system in place, and we don't have the software to drive the system, once we get the hardware in place.... Part 1 We currently have some RFID technology which gives us reading distances in the range of 6 Feet, what we need first of all is the ability to setup an 'array', where by we have a set of transmitters / recievers which correspond to one zone, and another set of transmitters / recievers corresponding to another zone, and so on and so forth. Please see attached diagrams for a better idea of what is needed.... In Summary for part 1 we need to source the following items, some sort of splitter to split the signal 1-x ways to create the array, quality compatible cables & connectors. The antennae will be provided, the array needs to be able to be taken apart. Part 2 Once we have the arrays working, we next need to source some sort of micro-controller / switch / relay solid state or otherwise to allow 'polling' of arrays, which would consist of switching the Tx / Rx 'cables' to an array, then asking the RFID Mini-Computer to poll for tags within the arrays range. Again all cabling etc... needs to be sourced, and the system needs to be built, as well as being able to be taken apart. Part 3 Once we have the hardware components built, we need some test software (to simulate polling , receiving of data). Next a full blown application. Please express interest, and qualifications, costing especially the first 2 parts of this project, once complete we can then do up a costing for the remaining database / application part..... Idealling would suit a development team that has some electronics / electrical engineering background, or has done a project involving micro-controllers.... Any other questions, feel free to ask....

Hi All,

Apologies for the delay, I was on holidays for the last 10 days or so....

To clarify a few general points....

The technology which we would intend to use is, and it's specifications can all be found on this website:

[url removed, login to view]

If any one has any better suggestions for technology that can read up to 6m, without the need for active (powered) tags then please let me know.....

Over the coming 2 days I'd aim to get back to everyone individually....

Regards,

Derek....

Hi All,

Apologies for the lack of contact on this project it was put on the back burner for the last couple of months. We have been looking at other technology, and we've now decided that probably the bext way forward is to use some sort of Ultra - High - Frequency Reader / Writer / Tags combination which is fairly standardised, which will give us a write distance of upto 3 metres, and a read distane upto 4 metres.

Next question is I would like each of the bidders to put forward a technology proposal outlining manufacturers of UHF Technology along with prices, reading distances and any other pros and cons assoicated with their selected technology, and how we might go about implementing an item tracking system in a retail environment. Whomever puts forward the best proposal for technology usage will be selected as the developer of the entire system....

The deadline fo r the proposals will be left at the 20th Of January giving everybody 10 days to come back to us...

That's about it for the moment....

Take Care....

Derek....
