Wireless high-speed data network planning tool
First Claim
1. A computer program product stored on a medium which, when executed by a computer, performs steps of:
- (1) assigning total output power values for plural cells of a modeled wireless communications network;
(2) distributing plural user equipment unit among the plural cells;
(3) determining, for a first cell, transmit power needed for services and channels in the first cell other than power for a high speed downlink packet service;
(4) using needed transmit power as determined by step (3) for determining power available in the first cell for the high speed downlink packet service;
(5) using power available as determined by step (4) for determining received power at a first user equipment unit on a high speed downlink packet service data channel;
(6) determining total interference received by the first user equipment unit from the plural cells;
(7) using received high speed service data channel power as determined by step (5) and total interference as determined by step (6) for determining a high speed downlink packet service data rate for the first user equipment unit;
(8) performing step (5) through step (7) for the plural user equipment units in the first cell and using the high speed downlink packet service data rates for the plural user equipment units to obtain a high speed downlink packet service data rate for the first cell.

Abstract
Tools and methods are provided to model and simulate the high-speed data channel and the traffic scheduling function, and tools and methods to simultaneously simulate the high-speed data channel and other voice and data services sharing the same radio carrier. The tools and methods estimate the quality of service and the capacity of the high-speed data channel, and also estimate the impact of the high-speed data channels on the quality of service and traffic capacity of other voice and data services on the same radio channel. The tools and method can be used in a wireless network planning tool to analyze a network that uses a radio carrier exclusively for high-speed data channels, such as cdma2000 EV-DO. The tools and method can also be used to analyze a network that combines high-speed data channels and CDMA based services on the same radio carrier, such as cdma2000 EV-DV or WCDMA HSDPA.
