To my knowledge , there is such management Software that can maintain efficient cellular & Wi-Fi seamless transition.... but it must be implemented in UEs

Seamless transition from WiFi to cellular (and vice versa) is inevitable -- not only for operators who must architect cost-effective network infrastructure, but also for consumers addicted to always-on life styles. But as Rick points out, I suspect how to manage the different wireless connectivities must be truly a work in progress.

The hardware consists of separate WiFi and cellular chips, nothing special. The secret sauce is in management software that lets users migrate to and from WiFi and cellular connections without needing to enter passwords (more than once) and lets carriers manage the traffic intelligently. This is very much a work in progress that is still in a crude stage today in need of better standards and implementations.

Mobile device will need to consume more power to switch between wifi and cellular network.

Is it just a bundle of chips put together in a small box or there is indeed some special technology that enable such multi-system pico cell to be economic to build?

"Cellular does handoff, WiFi cannot." WiFi can do handoff as well. But not sure whether it is as reliable as 3G.

There is a lot in terms of marketing ploy here. It is possible to put them in a single package, but as pointed out earlier, the physical and MAC layers are very different. Cellular does handoff, WiFi cannot. Cellular has robust security features, WiFi does not. The bandwidths are different, so are the frequency bands. The marketing ploy indicates that radios will remain separate, but handsets can sense and switch to WiFi if it sees one. But that does not mean seamless nor handoff from one to another. That part is a myth.

If Wi-Fi and Cellular services are merged into one the Quality of Service of Carriers will be affected a lot, it is not becoming clear that it will be cellular over wifi or it will be both the system working simultaniously if later is the case it will tend to licencing issues as well.

Roaming between different physical/ link layers is no doubt a hot feature. Consumer do not only demand high speed access but also look forward to streaming continuity. I certainly don't want to have my streaming action movie pause for a few seconds while I am on a road trip to Yellow Stone. Leveraging the already deployed femto cell will definitely improve the coverage, which effectively enhance user experience. Mobile network carriers will have great incentive to do so. I wonder what kind of business model they are envisioning since the broadband is paid by the subscriber if the femto cell is installed at home or office.
