Simultaneous Communication

[davidshap]

Hi-

I am new to Synapse products. I like what I've seen so far but I am a little concerned about the Nodes being able to handle simultaneous signals.

I am wondering exactly how quickly the nodes communicate with each other? Is it a fraction of a second or can it sometimes be longer? Would there be a collision if two nodes awoke from sleep mode and each tried to send a signal to the master node within the span of a few seconds?

Hope this makes sense. Thanks.

The speed of communications depends on how much data you are trying to communicate. However, in most cases, SNAP can communicate a command and have the associated action completed in only a few milliseconds.

Collisions will occur if two nodes attempt to communicate on the same channel at the very same moment in time (messages sent several seconds or milliseconds apart will avoid one another). SNAP has built in functionality to overcome these situations. This includes things like carrier sense, collision detection and collision avoidance methods. Also, messages sent to a known address will be re-transmitted until that device responds with an acknowledgment (or after after a specified number of attempts). Other configuration parameters can help avoid or detect collisions.

Great, thanks for your help.
