Both Femtocells and Wi-Fi offload do solve the backhaul issue by using customer or 3rd party links. (DSL, DOCSIS, T1/E1, WISP or otherwise).
Femtocells are tiny mobile cellsites using the mobile operators' licensed spectrum, supporting all handsets and all services. Thus femtocells are a great way to extend coverage. If you want mobile voice service in a place where macrocell coverage is poor, a femtocell could be ideal. However, that's the only place where femtocell's have the advantage.
As a solution for mobile data capacity, Wi-Fi wins, because of the following reasons:
That's why we think that eventually Wi-Fi will trump Femtocells, especially now the problems related to seamless integration in carrier networks seems to be solved by various wireless network equipment vendors.
The carrier Wi-Fi space is red hot right now, driven by the explosion in demand from mobile operators using Wi-Fi to augment their 3G/4G deployments and offload a portion of mobile data traffic to unlicensed spectrum.
But that offload is not always a smooth experience for users, because traditionally Wi-Fi has been treated more as a separate network with the device attaches to Wi-Fi under its own control.
Therefore wireless network equipment vendors are now launching a suite of software and hardware aimed at integrating Wi-Fi into carrier networks where Wi-Fi, LTE, W-CDMA and GSM are managed from one platform. This real-time traffic steering solution is a network software upgrade that constantly assesses performance indicators in both the 3G/4G network and the Wi-Fi network to find the best connection for the user. Besides that these solutions also provide support for access selection to enable load balancing between 3G/4G and Wi-Fi networks.
Besides this some operators are rushing to deploy Wi-Fi access points in desirable locations, often with the intent of replacing them down the road with dual mode 3G/Wi-Fi and LTE/Wi-Fi small cells, which is even further accelerating the pace of Wi-Fi deployments.
Because WiFi offload will open up a whole new world of service capabilities, it is of paramount importance to determine those services that will lead to maximum customer satisfaction and loyalty, and related incremental revenues.
