OVERVIEW 2nd generation systems like GSM, were originally designed for efficient delivery of voice services. UMTS networks are, on the contrary, designed from the beginning for flexible delivery of any type of service, where each new service does not require particular network optimisation. In addition to the flexibility, the WCDMA radio solution brings advanced capabilities that enable new services. Such capabilities are: 

High bit rates theoretically up to 2 Mbps in 3GPP Release ’99, and beyond 10 Mbps in 3GPP Release 5;



Low delays with packet round trip times below 200 ms;



Seamless mobility also for packet data applications;



Quality of Service differentiation for high efficiency of service delivery;



Simultaneous voice and data capability;



Interworking with existing GSM/GPRS networks.

The purpose of the radio network planning is to achieve the required number of sites and sites’ configurations, which fulfills the requirements of coverage, capacity and quality based on the frequency resources, equipment performance and economic factors. The Islamic Republic of Afghanistan is a landlocked and mountainous country in south‐central Asia. This report presents the UMTS network dimensioning process and simulation result of 7 cities. The site numbers of 7 cities are shown as followed: Table 1

NETWORK PLANNING PROCEDURE ZTE adopts a network planning strategy of “Holistic planning, construction by stages”, and makes most use of operator’s present network resources to get most valuable return with least investment. The destination of “Holistic planning” is to build a best network quickly. “construction by stages” is an important method to guarantee this destination. The first phase is to solve the problem of coverage. The coverage in first phase should achieve the final coverage target of network planning as possible as can. The next phases are to expand the network capacity smoothly. It is also a continuous optimization process to ensure the network keeping its best state of coverage, capacity and service. ZTE follows the following workflow for radio network planning: Requirement Analysis

Propagation Model Testing and Tuning

As the above picture shows, the whole radio network planning process is very complicated and contains a work loop of testing, analysis and optimization. In this document, we mainly focus on the pre‐planning part which includes requirement analysis, propagation model testing, dimension estimation, site selection and simulation.

COVERAGE PLANNING Coverage Planning Process

Figure 2 Coverage planning process

The coverage estimation process is as follows: PLu, PLd, PLp from Link budget Continuous services in uplink, downlink, and PCPICH’s max allowable path loss by link budget; C=max(PLu, PLd, PLp) Maximum one of the above uplink , downlink and PCPICH’s result; R=propagation model(C): Cell radius from path loss based on propagation model;

One Node B’s covering acreage; Node B number=Total acreage/ E

4.2

Propagation model The propagation model describes the average signal propagation in certain environment. It often denotes the path loss as a function of distance of the separation between the transmitter and the receiver. ZTE propose to adopt Standard Macro Cell Model, which is supported by the simulation software Enterprise, Aircom, with the following formulas: Pathloss

= k1 + k2log(d) + k3(Hms) + k4log(Hms) + k5log(Heff) + k6log(Heff)log(d) + k7Diffn

+ C_loss here: d

Distance from the base station to the mobile station (km).

Hms

Height of the mobile station above ground (m).

Heff Diffn

Effective Node B antenna height (m). Diffraction loss calculated using either Epstein, Peterson, Deygout or Bullington

Equivalent knife edge methods. k1

Intercept

k2

Slope

k3, k4 Correction factor of mobile antenna height k5, k6 Correction factor of effective Antenna Height k7

Correction factor of diffraction.

C_loss Correction factor of different clutter type. The propagation model can be tuned by applying a mathematical fitting algorithm to the raw data collected from drive test thus that the most proper k‐factors can be deduced. For this UMTS pre‐planning project of Ecuador, currently no propagation model testing and tuning is performed, thus ZTE select the propagation models according to the clutter distribution and the site distance of the existing WCDMA sites, which are shown below (Here we divided the planning area into Dense urban, Urban and Suburban).

Eb/No, receiver Noise Figure etc. WCDMA is an uplink coverage limited system, generally only uplink budget is taken into consideration. The table below is a general link budget process: Uplink budget process‐CS 12.2K

C APACITY ESTIMATION PROCESS Capacity Estimation Process

Figu re 3 Capacity Estimation Process Step 1: input traffic model, and other parameters which are neglected here, like handover percentage, Eb/No, etc. Set an initial number(generally from 1). Step 2: calcualte the uplink and downlink interference load, consumed downlink power by all services. Step 3: compare the above result with their respective threshold. If all the results are under the thresholds, then move on the next step; if anyone of them is not, increase subs/site and return to step 2. Step 4: use the above subs/site and total forecast subs number, to calculate the site number.

5.2

Capacity Analysis Results With the traffic model and forecasted subscriber number, we could work out that the coverage sites numbers can satisfy the capacity requirement. So in this project, the sites are limited by coverage requirements.

SITES DISTRIBUTION

Figure 7 The Patterns of the Antennas

Digital Map: The resolution of the digital map used in the simulation is 20m, PLANET format. The explanation for the deviation of simulation: Network simulation, which is used to predict the performance of wireless network, can be the validation and reference for planning scheme. However, because simulation data is not the drive test data obtained from the real network, there are some deviations between the simulation result and actual testing result. The factors that could result in the deviation between them are listed as follows: 

The complexity of radio propagation environment; propagation features has great difference in different environment;



Approximate prediction methods are used in simulation system, which can leads to the deviation between them;



Engineering quality also could lead to the simulation deviation;



Traffic spread in simulation is different from the loading in the practical network;



Changes in buildings development brought about by fast economic progress took place after the purchase of digital map, the new changes cannot be reflected in the digital map; and



14

there is no exact building height in the digital map with 20m or 50m resolution, which are usually used. Consequently, the reflection and diffraction cannot be exactly calculated in the simulation. The limitations of digital map listed above also can bring deviation.

Best Server The concept of best server represents the best serving cell for each pixel by pilot power. Here a pixel stands for a specific location in the map raster of the area under planning. The most likely server at a pixel is the cell with the biggest pilot power. Best servers for each Node B are illustrated in the following picture.
