Self-installation is all the rage now. Broadband internet, TV, cordless phones, computers...... all "plug and play". Instead of sending a technician round to your home to install, setup and configure the equipment, its simply delivered to your door or collected from the shop. This has enabled dramatically reduced prices and rapid growth in these markets.
The cable industry is still somewhat different, sending a technician out to install your set-top box even when you've just taken moved in and are reconnecting to the same cable service.
Femtocells are very much in the former category, being designed for self installation to keep costs down and we can expect this approach to work in at least 90% of cases.
