The RFM-102 module connects 802.11 stations, APs, and application specific devices (ASDs) to create advanced test configurations. Among the common uses of the RFM-102 are to create and manipulate Basic Service Sets (BSSs), enabling users to perform such tests as roaming and hidden stations.
The RFM-102 consists of RF ports with and without programmable signal attenuation. APs are typically connected to the programmable ports. Stations—including Station Test Module with vendor-specific NICs and emulated softClients created with the testMAC Module—are generally connected to the unattenuated ports. The programmable attenuators enable virtual positioning of APs and clients to simulate dynamic movement. Each group of RF ports can be configured to create two independent BSSs. The second group of attenuators then adjusts the virtual position of that BSS relative to the other BSS on the module or other BSSs from the chassis backplane. This flexibility makes complex roaming tests with overlapping BSSs possible.
The RFM-102 offers the following features:
- Support for hidden station configurations (>110dB AP-to-station isolation) and multiple-BSS configurations
- Highly accurate, controlled attenuators that operate over 90dB range for 802.11a, b, and g bands.
- Central test management and control of wireless client parameters by Azimuth DIRECTOR™ Test Executive software
