Yeah, right.Femtocells may look unlikely, but there's a possibility they may win out.
While I'm no longer naive enough to believe it will be one or the other, the idea that a femtocell, which is the tool of the operator, so you'll need one for each proprietary service operator (or change it when you change providers), which you probably therefore aren't willing to pay for, that will use your connectivity (and be prone to its weaknesses) is going to win a major portion of the market where the alternative gives you much greater freedom seems unlikely.
A Wi-Fi access point gives you infinitely greater choice of client devices, services, service providers, that could well outweigh the small performance advantage of limited handsets, limited services, single provider proprietary solutions. And remember, either solution uses the same backhaul.
I don't know the details, but there'd be a lovely irony if your femtocell used VoIP to backhaul the traffic to where you can be charged for it... If the argument that the cellular technology works more reliably from the handset to the femtocell, then why use it instead of DECT or any of the other cordless technologies that we know? There's already a Skype handset that does this.
Makes for a simpler phone? Perhaps, but sales figures for dual-mode handsets (Wi-Fi/Cellular) don't indicate there's any barrier to their uptake.
What vodafone, and the rest of the comfortable incumbents will learn it's not what they desire, but what the customer wants, that occurs in non-monopoly environments. When you read the list of advantages of femtocells, note how many are advantages to the operator, rather than the customer."Vodafone has no desire to subsidise a Wi-Fi handset"
The dead giveaway:
Not to disparage those operators who are going with UMA (AKA GAN) services like T-Mobile and Orange.But there's an even more powerful business reason why mobile operators want to sell femtocells: they hate Wi-Fi, because users own it and can use it at will.
Even in duopolies and oligopolies, there tends to be one less powerful who will seize the chance to change the rules.
Most emperors have a few tailors turn up to sell them new clothes, few as transparently a bad idea as this one.
