I used D-Link DWL-G810. a single port wireless transmitter. it is about 3 inches (75mm) square with a small antenna. a power supply plug and a LAN port
uses a short cable to connect to the CS 2. I have done this when I was controlling the layout with software through the CS from my computer in another room (which had the router).
so obviously the CS was connecting to the router.

Thanks, Can you post a link as to where you got it though? I'm looking, but i can t seem to find it.

Thanks!

It sounds like a pretty sound theory. Fortunately, I managed to find a wireless repeater thingy that works, so I don't think I'll be trying it out anytime soon. However, if I ever find other devices that I might need, I'll think about it.

In another story from the early 90's I was involved in the certification process of modems for Laptops. As long as these were discrete PCMCIA devices, they could be certified in their own right. But when the modem functionality became an integrated part of the "system board" the certifying agency required the scope of certification to be the whole machine (i.e. under various adverse electrical, environmental and usage scenarios).

While admirable for there diligence, all this did, aside from increasing the cost of product delivery, was annoy marketing because they couldn't bring the product quickly to market - it was common knowledge that some competitors either didn't know or conveniently forgot about the Telco certification requirements (I appreciate that in this country there is a legal standing compared to other jurisdiction ). Also customers started buying direct from other countries (yes you could buy from the internet in the 90's... and being laptops, power adapters were less of an issue)

Maerklin have enough compliance issues with the electrical noise generated by model locomotive motors.
Anecdotally even the 6070 attracted the ire of the FCC and EC and that was only IR!
Our US colleagues may complain that they have to pay extra for a piece of suppression equipment that isn't needed in other countries, but that this what Maerklin have to do if they want to do business there (to be fair all the US manufactures have to (should) adhere to the same level of compliance).

If you extend this to the far more varied telecommunication requirements of each and every country you will be out of business yesterday unless that is your prime function. There may be a time when this feature is "required" by more than 5% of modelers, but it would have to get to well over 50% before it should get on the wish list to be seriously considered for integration within a product.
Technically, there may also come a time when the isolation of signals (track signal v wireless) within a control unit will meet the stringent levels needed , but until then I believe that having the transceiver a modest distance outside the box is a preferable option.

So I say Maerklin should stick to there knitting and continue forward unhindered by aspects that do not directly relate to Model railroading. There are so many vendors that are far better placed to cater with the wireless compliance aspect without it slowing down the process of updating a train controller.
That said, any entrepreneurial dealer who saw a desire by his clients for this could easily arrange a partnership with a local rep (cisco, netgear .... ) and package a solution.

Use a dedicated router such as the Netgear N300 on the CS 2. I assume that the iPhone app for the CS2 is analagous to the TouchCab app I use on an iPod Touch with the ESU ECoS 2.

You can get the N300 at Walmart or Radio Shack
