Don't forget that interference flows both ways; as I understand it, 802.15.4 is much lower power than 802.11 and may get overwhelmed by the much "louder" 802.11 signals. As we all know, 2.4 GHz is already a wasteland of noise, so that will make it even worse.
IIRC, however, there are a couple of channels in 802.15.4 that fall between 802.11 channels 1,6, & 11. We have a single instance of 802.15.4 for specialty door looks in one location (related to accessibility for special needs students) and we worked with the vendor to choose one of these channels. Doesn't seem to cause interference, but we don't have a wide spread deployment like this would be. What is it with vendors wanting to use 2.4 for everything? The 900MHz band is part of the 802.15.4 standard and should theoretically have longer range to boot.

Our facilities department is looking to upgrade some of our lighting infrastructure to use lower power LED light fixtures. One of the proposals is to replace all the lighting and the existing Lutron lighting control system with a relatively new Eaton WaveLinx wireless lighting system. Unfortunately, the vendors who came in couldn't even explain what spectrum(s) the infrastructure would run on. A quick review indicates that the controllers operate on WiFi or wired LAN for control access and 802.15.4 for communication (@ 2.4MHz) between all the various devices (dimmers, switches, occupancy sensors, lights, etc). Each controller currently operates as a standalone since they still don't have a centralized management environment and they're single user access only. We're particularly concerned about any potential interference issues that might arise within our existing and future wireless environments. I was wondering whether anyone has any familiarity with this or similar environments and whether you'd be willing to share your thoughts and experiences on them.
