How to Improve forward Effective throughput in 1X EVDO?

Can anybody explain with parameter? I am From China I am working with Huawei, As per PRactice I Suggess U to get Highest Throughput Set Below, Active search Window = 80 Neighbor Search Window =80 Remanig Search Window = 100 Why ??? As per EVDO Formula Forward throughput (DRC) based on C/I C/I = Active Pn Strength / Total Interferance+(Same Pn but Not in Search Window) So If serch Window Increase SO Active Pn Fall More in its Search So C/i Great So DRC Good So Speed Increase,...
