The CDMA Femtocell Test Case
The Femtoforum defines a Femtocell as a low-power access point that operates in licensed spectrum to connect standard mobile devices to a mobile operator’s network using residential DSL or cable broadband connections. The Femtocell improves the quality of mobile service when indoors, particularly in the home. The Femtocells work as a mini cell tower inside the home, improve the quality of mobile service when indoors, and also offer the benefit of offloading carriers’ radio access equipment.
The CDMA Femtocell test case simulates Femtocells as well as mobile nodes in the mobile operator’s network.
With this test case, you define:
-
The number of subscribers per Femtocell and Femtocells connecting to the FGW
-
The RP interface (IPSec) connecting the Femtocell to the FGW
-
The FGW connecting to the Security Gateway (SGW) and the Network Host

Test Terminology
Femtocell Gateway (FGW)
The mobile devices connect to the mobile operator’s network device known as a Femtocell Gateway (FGW). The FGW is made up of 2 functions:
-
A security gateway which terminates the secure IPSec connection from the Femtocell to the FGW.
-
The Network Gateway itself that handles the signaling and data from each connected Femtocell.
IPsec
One active IPSec tunnel is simulated for each Femtocell node.
Test Options
When your test activity measures processing capability rather than rates, you can expand the scope of the test:
-
Encrypt Data Traffic traversing the Femtocell/RP with the RP IPSec feature.
-
Define the number of Mobile Subscribers per Femtocell and number of Femtocells emulated.
Measurements
Measurements collected for this test case are reported on the following tabs. Additional measurements may be available depending on the test activity and options executed with the test case.
