While I have been around this space for a couple of decades, I have seen and heard about every imaginable business model. Some make a lot of sense, some well it least my opinion do not. So at the end of the day the CIO in any organization needs to step back do their discovery and make the companies be totally transparent. As said before in the wireless world it pretty much comes down to the laws of physics and costs. In many previous blogs I have discussed the rationale for the separation of the WLAN from the DAS, especially with 802.11n (MIMO). While technically anything is possible, if these discussions come up, one has to ask themselves what are the CAPEX and OPEX costs and is this a business model to support cost in technology changes effectively in the future? Will my WLAN provider ensure complete warranty support? At the least get multiple quotes, separate DAS, separate WLAN, converged and compare. Get everything in writing about support of changes on the design if converged on a no cost basis for at least five years. Dedicated spectrum for wireless medical devices…interesting. One has to ask themselves if WMTS was such a great success, then why have Draeger,and Welch Allyn moved from WMTS (and others to follow) from dedicated and very proprietary radios to 802.11x on a converged enterprise network? Because is saves a lot of costs and is proven. While I am staying neutral hear, just remember that Mr. Chambers, CEO of Cisco Systems, Inc. made a very profound statement in 2005 at HIMSS. The days of proprietary networks in healthcare are over! The DAS Financing Model recent in 2010 and 2011…a lot of smoke and mirrors here…it seems. Will a venture funded third party entity fund the cost of a DAS and implementation at a lower cost than owner operated? Not really. Will the carrier finance the cost of the neutral host DAS and then let their biggest competitor join on a no cost basis? Not really. Going forward the market is shifting fast and the new DAS business model is for the owner to own the technology, they select the integrator to install the technology (notice I said technology, not architecture), then have the carriers finance part or all of the this and have the integrator provide the support.
