Charlei,
My information is that the DCS Explorer will work in passive mode. However, at this stage in its life, nothing can be taken as gospel and everything is subject to change.
Most of this thread is based on rumor, supposition and what people have heard (yours truly included). There's little or no real information regarding this product. AFAIK, a prototype has yet to be built.
However, now that I think about it, what makes the explorer different from a TIU or a DCS Remote Commander is that the explorer needs to have its WiFi radio constantly powered. If it wasn't, it would be a real problem to have to reconnect to the app or the home network every time track power was turned off.
