Forward and reverse link capacity determination
First Claim
1. A method of determining a wireless system capacity, the method comprising the steps of:
- determining a reverse noise floor;
obtaining a plurality of forward code domain measurements and corresponding reverse noise measurements;
analyzing the obtained measurements so as to obtain a plurality of data values, wherein the plurality of data values includes (i) a plurality of data values that indicate a number of active users, and (ii) for each data value that indicates a number of active users, a data value that indicates a corresponding reverse noise rise (RNR); and
determining a maximum number of users such that a probability of exceeding a predetermined RNR is below a threshold, wherein the probability is determined from a ratio of a number of the measurements having an RNR below the predetermined RNR to a number of measurements corresponding to those at or below a specific number of active users.

Abstract
Determining RF capacity of a wireless network and measuring BTS performance. Preferred methods include collecting forward link data at a BTS transmit port, where the data includes the power level associated with each Walsh code of each sector for each carrier over a predetermined time interval, and then processing the data by identifying each channel as using either second generation CDMA technology (a “2G” call) or third-generation technology (a “3G” call). Voice and data may also be identified. The power level may be determined by measuring a signal level (e.g., dB), and subsequently accounting for any RF losses through a calibration step, and finally converting the power-per-Walsh code to an absolute power level (e.g., dBm, or watts). The average user power per link (ppl) is then determined and the number of users per technology (2G versus 3G) is also determined.
