I recently heard Prof. Simon Saunders (who has a much impressive background that i thought of) at Cambridge Wireless International conference speaking on Thinking Networks. One of the things mentioned that struck me is how convenient it would be with femtocells to offload the data on the internet directly without going through the operators core. This would mean less data on the backhaul for the operators and since data would have to travel through less nodes, the speed and reliability could be higher.
There is a slight problem though. In the recently concluded Femtocells World Summit (which I have blogged a lot about), AT&T has been harping about its data caps while using Femto. AT&T wants that the Femto's should mainly be used for voice and for data the users should generally switch to using WiFi. Their reasoning is based on the fact that they are not allowed to perform data offload as mentioned above due to FCC regulations. In fact the same problem may be present in other countries and would hamper the Femto growth in time.
Femtocells are better for data usage as I have mentioned in past because they provide seamless coverage and better data security. It should also be pointed out that the battery drains faster when using WiFi as compared to the mobile Internet.
When a user uses Femtocell, he is already using his broadband data allowance and if there is additional restriction placed in terms of data caps on the Femtocell, the users may just revolt and avoid using Femtocells at all.
Voice coverage advantage is good but users may prefer to switch operators if its just voice that they are using Femtos for. While the use of fixed line phones have decreased in the past (thanks to voice bundles on mobile), some users are switching back to using landlines because of the voice clarity and no reception problems.
The Femto manufacturers and the operators will have to act fast if they want their future predictions to come true.
