    摘要: A method and system for estimating the number of transceivers in a service area (100) are disclosed. A calibration area (102) is selected from the service area, and a defined number of transceivers are placed in the calibration area. Input parameters are determined for the defined number of transceivers, which are refined so as to ensure that the input parameters satisfy a customer-specified requirement. The measured input parameters for the refined number of transceivers are used to calibrate a Radio Frequency (RF) coverage prediction tool for the calibration area. The calibrated RF coverage prediction tool is further used to estimate the number of transceivers in the service area.

    摘要: A CDMA mobile communication system is operated asynchronously while using common forward channel PN and Walsh codes. Such operation is enabled by devices in the system that provide measurements of the instantaneous offsets between PN codes of neighboring base stations. Knowledge of instantaneous offsets may be maintained and used to identify base station signals to enable handovers to neighboring base stations. Instantaneous offsets may also be processed over time to identify states of imminent collision so that corrective action can be taken to avoid or minimize collision effects.
