1.1 Introduction to RND Radio Network Dimensioning (RND) is a
software program used by network planners to plan the GSM and UMTS
networks at the early construction stage. The RND covers the
following functions:
z Network dimensioning by using different design types for
different application scenarios z Independent calculation of each
module, or the inheriting of calculation results among
modules z Network dimensioning in multiple cities and multiple
networking scenarios
simultaneously z Importing/exporting parameters and calculation
results, and importing the parameters
and calculation results into the RNP output template.
Currently the RND supports both GSM networks and UMTS networks,
and applies to stand-alone systems only.
1.2 RND Application Scenarios The RND is used to estimate the
network scale and required resources during the network planning
stage. Based on different requirements on network specifications by
different operators, the RND adopts different design types. Table
1-1 lists the mapping between network requirements and design
types.

Network dimensioning based on U-Net coverage prediction
function. The procedure is as follows: First calculate the cell
radius based on the link budget function of the RND, forecast the
coverage and adjust the site distance in the U-Net, and then
estimate the network scale by inputting the adjusted cell radius in
the dimensioning modules of the RND.

calculate the maximum coverage radius of TCHs or pilot channels
by using the maximum path loss and the traffic model. This module
covers two parts:
z Continuous coverage service link budget This part can
calculate the service coverage radius if the transmit power of the
channel is available. The continuous coverage services include the
Circuit Switching (CS) services and Packet Switching (PS) services
of R99, High Speed Downlink Packet Access (HSDPA) services, High
Speed Uplink Packet Access (HSUPA) services, and Multimedia
Broadcast Multicast Service (MBMS).
z Pilot link budget This part can calculate the coverage radius
of the pilot channel, that is, the cell radius when the transmit
power of the pilot channel is available.
The link budget module does not need to inherit the calculation
results of other modules, and outputs the cell radius.
1.5.2 Cell Edge Throughput & Power Dimensioning This module
can estimate the following items:
z HSDPA cell edge throughput The maximum data rate of the HSDPA
for specific terminals at the cell edge is calculated on the basis

for specific terminals at the cell edge is calculated on the basis
of the cell radius.
z Continuous coverage service power The transmit power of TCHs
is calculated on the basis of the cell radius.
z Pilot Ec/Io The pilot RSCP threshold and Ec/Io are calculated
on the basis of the cell radius and pilot power.
z Pilot power The transmit power of pilot channels is calculated
on the basis of the cell radius.
1.5.3 Number of Sites Dimensioning Based on Link Budget The
number of base stations that takes the dimensioning margin into
consideration is calculated on the basis of the cell radius.
This module inherits the cell radius outputted by the link
budget module, or users enter the cell radius in this module. It
outputs the number of base stations that takes the dimensioning
margin into consideration.
1.5.4 Number of Sites Dimensioning Based on U-Nets Prediction
