Method and system for determining total isotropic sensitivity using rssi measurements for wimax device certification

A test setup system configured to determine a total isotropic sensitivity (TIS) of a wireless broadband client device comprising a device antenna and an embedded radio module, the test setup system comprising a processing element and a memory element configured to:

• log a received signal strength indicator (RSSI) reported at the radio module for each of a plurality of antenna polarizations of a transmit antenna and for each of a plurality of platform orientations;
• perform a single point measurement of module sensitivity at a reference orientation and a single polarization of the transmit antenna;
• and
• calculate the TIS as a correction to the single point measurement of module sensitivity,
• wherein a correction factor to correct the TIS is based on a difference between an average of the logged RSSIs and an RSSI at the reference orientation and polarization.

A computer-readable storage medium that stores instructions for execution by one or more processors to perform operations for determining a total isotropic sensitivity (TIS) of a wireless broadband client device, the operations comprising:

• logging a received signal strength indicator (RSSI) reported at a radio module for each of a plurality of device antenna polarizations and for each of a plurality of platform orientations;
• performing a single point measurement of module sensitivity at a reference orientation and polarization;
• and
• calculating the TIS as a correction to the single point measurement of module sensitivity,
• wherein a correction factor to correct the TIS is based on a difference between an average of the logged RSSIs and an RSSI at the reference orientation and polarization.
