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

$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

Nominal Planning
Nominal planning is more detailed planning based on
dimensioning results,
In t"e nominal planning- all sites are positioned accuratel%
in t"e R. planning tool, $"e output is t"e nominal plan and
t"e t"eoretical specification for eac" site, Nominal planning
is also called pre#engineering p"ase and pre#design p"ase,
.rom t"e specification of t"eoretical sites- a searc" zone
will be defined and used as t"e input for site searc",
