Disclosed herein are methods and systems for emulating testing-plan channel conditions in wireless networks. One embodiment takes the form of a process that includes identifying a data-rate threshold and one or more testing-plan channel conditions. The process also includes identifying testing-scenario channel conditions corresponding to the testing-plan channel conditions. The process also includes selecting an attenuation offset based on a comparison of the one or more identified testing-scenario channel conditions to the one or more identified testing-plan channel conditions. The process also includes measuring a data rate with a testing-scenario attenuation level set equal to the selected attenuation offset. The process also includes storing testing-plan-compliance data associated with the measured data rate and the data-rate threshold.

A method and apparatus for identifying a geographic area having undesirable wireless service is described. The method includes, collecting Radio frequency (RF) environment information of the wireless service. The method further includes, determining locations of a plurality of subscriber units based on the RF environment information. Further, the method includes, processing the RF environment information and the locations of the plurality of subscriber units to identify the geographic area having the undesirable wireless service.

Method and apparatus for identifying a geographic area having undesirable wireless service

Error vectors are added to any position estimate determined by Location finding equipment (LFE) in order to give a corrected position estimate. Error vectors are determined utilizing calibration terminals (114), which are roaming vehicles that move throughout the communication system's (100) coverage area. Each calibration terminal (114) comprises a remote unit (113) coupled with an independent position determining system (167) such as a Global Positioning System (GPS) receiver. Error vectors are determined by periodically polling calibration terminals (114). In response, each terminal (114) sends back a reply message containing their actual, independently determined location, along with periodically broadcasting a known sequence at increased power utilized by the LFE in determining a position estimate of the calibration terminal (114). The difference between the actual, and LFE determined position estimates are utilized in calculation of error vectors.
