What existing buses or network standards exist for attaching diverse sensors for monitoring or control? Something functionally similar to BitBus or the proposed standards for residential networks (i.e SmartHouse) might do the trick. The essential ingredient is to allow flexibility in appending new nodes and varying degrees of bandwidth for different sensors. i.e. switches to cameras. a fixed, time-slotted, time division muxed doesn't seem to be flexible enough and ties up the network especially as more nodes are added. An additional question relates to chip(set)s that allow easy frequency division muxing. The cable TV that comes into a house has many channels any one of which can be selected and each of which is running a full-bandwidth all of the time. Are there simple selectable tuning methods for getting the signal out? thanks Aka : Kevin Dowling Bell: (412) 268-8830 Arpa: nivek@rover.ri.cmu.edu Mail: Robotics Institute Carnegie Mellon University Pgh, PA 15213-3890 --
