A very good initial analysis. It also worth stating that femtocells work with standard, existing handsets - unlike dual-mode WiFi solutions. They also require good quality (low latency) but low bitrate (for voice) broadband. A significant cost for mobile operators is backhaul, which could be prohibitive if wide area mobile broadband takes off - hence offloading to femtocells where the customer provides the “site”, power and backhaul connectivity is attractive.

Femtocells need to be self-installing and pretty much idiot-proof to succeed - hence vendors are learning from and/or collaborating with DSL modem/WiFi hub manufacturers.

Many fixed operators make much less money from voice call revenues as a percentage of their business than mobile operators, so the argument about stealing voice minutes is weaker and for data traffic doesn’t hold.

There’s much more information on the business case at my website http://www.thinkfemtocell.com

And another thing, if we are talking about UMTS900, it is ultimately a capacity issue not a coverage one. Even if radio waves successfully penetrate buildings, a micro cell will not be able to cope in a densely populated data-hungry area.

I am not saying that femto cells are panacea, but could possibly address these issues IF properly developed, marketed and deployed.

Hi Giorgo,

I agree with you, the business case for femto cells is not so clear at the moment. This is also illustrated by BT evaluating the costs to deploy femto cells as too high and Ericsson saying it will not introduce suitable product lines until market is ready in 2009.

I disagree about the WiFi comment though. A femto cell would allow user to communicate at home with the same handset, while WiFi would require another handset - or another terminal (e.g. notebook computer) and suitable interfaces (UMA) to enable seamless transfer of calls between heterogeneous media.

It is simplicity for the end user that MNOs should aim for in my opinion with femto cells (but I am not sure whether a deployement of MNO-wholly-managed femtos is even possible - too many technical issues).

Dimitris.

I do not think femptocells have positive business case especially for Mobile Operators. Even for those MNOs who they do not have good 3G coverage indoors, sooner or later they will launch UMTS 900 which will solve that indoor coverage gap. The home femptocell industry will be dominated by WiFi at least for the next 3-5 years and not by 3G(HSPA) Access Points.
