Brief Introduction

Importance of RNP and RNO

Radio Access networ is more e!pensive t"an ot"ers

Different area "as different radio environment and

customized solution is needed

Relations"ip between RNP and RNO

RNP tae responsible for pre#sale period

RNO tae responsible for post#sale period

RNP is more important t"an RNO


5/33

$arget of RNP

Coverage

Achieve the required radio coverage with specified probability

Capacity

Meet the capacity requirements with acceptable block/delayQuality

Reach good QoS by linking the capacity and coverage

Cost

Minimied the overall cost of the network

$"e purpose of dimensioning is basicall% to give an

evaluation of t"e number of sites re+uired in t"e planning

Nominal planning is more detailed planning based on

dimensioning results,

In t"e nominal planning- all sites are positioned accuratel%

t"e t"eoretical specification for eac" site, Nominal planning

is also called pre#engineering p"ase and pre#design p"ase,
