An overview, tutorial or primer about femto cells or femtocells describing the essentials of what they are and how they work.

This femtocells tutorial is split into several pages each of which addresses a different aspects of femtocell technology and operation:

[1] Femtocells Tutorial
[2] Femtocells and interference
[3] Femtocells organization & configuration
[4] Femtocell network architecture
[5] Femtocell security
[6] Femtocells and health issues

Femto cells or femtocells are small cellular telecommunications base stations that can be installed in residential or business environments either as single stand-alone items or in clusters to provide improved cellular coverage within a building. It is widely known that cellular coverage, especially for data transmission where good signal strengths are needed is not as good within buildings. By using a small internal base station - femtocell (femto cell), the cellular performance can be improved along with the possible provision of additional services.
