Hi all, I'm wondering if anyone here has got any interesting (900MHz) 802.15.4 testbed setups? What I would like to do here is to connect up a bunch of nodes via an RF matrix switch/mixer/attenuator, so I can run deterministic tests on the meshing functionality. The ability to control the strength of the signal received at each node on a per-source basis is the key feature I'm after. For now something on the order of 4-6 nodes would be quite sufficient. I haven't had any success finding any commercial equipment (or even DIY) available to enable this type of setup. Has anyone here done anything similar and can provide some recommendations?
My fall-back position will be to do this in a software layer above the radio driver, but I would very much prefer to be able to do it in hardware if possible. Simply distributing nodes around the place will not be sufficient for the testing I want to do, and it would also be a pain to firmware upgrades since we haven't got over-the-air upgrades going (yet).
