A tiny little detail…
On August 24 we will be testing a 12 car setup. If that goes well, the approach will be scaled up to 36 cars and this will not require any hardware changes to the throttle controllers or the in-car decoders. The part that will need to change is the Wireless Hub. This is designed to accommodate 1,2 or 3 communications modules. Each module can handle up to 12 cars. They are designed to be synchronised together so all three modules will either transmit or receive at any moment in time. This synchronisation piece is straight forward but not yet tested.
The design concept throughout this development exercise is to eliminate any potential communications bottlenecks as car numbers increase. Every car has a clear set of hop channels (known as frequency division multiplexing) and pre-allocated timeslots (known as time division multiplexing).
Next let’s see whether practice matches theory ;)
