Abstract

A system increases the capacity of a CDMA network having a plurality of cell sites (4110, 4120, 4130). The system defines a pool of frequencies (F1, F2) available for assignment, and assigns one of the available frequencies (F1, F2) to each of the cell sites (4110, 4120, 4130) so as to minimize the number of neighboring cell sites assigned a same one of the available frequencies (F1, F2). By deploying different frequencies (F1, F2) in the cell sites (4110, 4120, 4130), the amount of interference caused by neighboring cell sites reduces. As a result, the capacity of each of the cell sites (4110, 4120, 4130) operating at a single frequency (F1 or F2) can be increased, so long as there remains sufficient power to reach the mobile units (4200) operating within the cell site (4110, 4120, 4130). The system attains maximum benefits when the cell sites (4110, 4120, 4130) are located close together and the propagation exponent is low (for example, 10-20 dB/decade).

Claims

Claim
1. A computer-implemented method for optimally increasing capacity of a digital network having a plurality of cell sites, comprising the steps of:

(a) defining a pool of frequencies available for assignment;
(b) selecting one of the cell sites;

(c) determining frequencies assigned to the cell sites neighboring the selected cell site;

(d) assigning one of the available frequencies to the selected cell site based on the determined frequencies assigned to the neighboring cell sites;

(e) determining an amount of interference at the cell sites caused by the neighboring cell sites after assigning frequencies to all of the cell sites;

(f) comparing the determined interference amount to a predetermined threshold;

(g) increasing the pool of frequencies available for assignment when the determined interference amount is greater than the predetermined threshold; and (h) repeating steps (d) through (g) using the increased number of available frequencies until the determined interference amount is less than the predetermined threshold.
