1. INTRODUCTION

In a fast growing Mobile market, Operators seek a comprehensive and reliablequality of service. Undoubtedly Wataniya is an Operator that will have thepotential to develop numerous services such as WAP through GPRS technology,and therefore acquire new subscribers. Nowadays, the need for a reliable and

seamless mobile service in Algeria starts to be more and more perceivable. In thenearest future, we will have to face fierce competition and Operators will have tooffer coverage in, not only outdoor locations, but indoors as well. As a goodexercise Wataniya wants to deploy a complete indoor solution at the MSC BabEzzouar premises. This should lead to better testing of Wataniya network usingdifferent features. Wataniya will therefore have the possibility to give its ownemployees the opportunity to test the network reliability and QoS. We areconsidering a number of employees between 400 and 500 who will be based inBab Ezzouar. Therefore, not only indoor coverage will be considered but

capacity/blocking as well.

This document highlights the complete process of indoor design for coverage andcapacity in the MSC premises in Bab Ezzouar.

This document is organized as follows : Section 2 comprises a summary of theTEMS indoor measurements (walk test), whereas Section 3 and 4 encompass theproposed design using Ericsson RBS located in the ground at the MSC, alongwith a rough capacity dimensioning based on the data supplied by the logistics

department (# people expected visitors subcontractors etc ) Section 5 is

TRUs for the sake of consistency with Ericsson equipment. Each sectorhandles about 4 floors. The reason is that if we use only one sector, we wouldhave to split the power to reach the upper floors leading to major lack of RFpower. However, if the BTS was located somewhere in the middle (vertical wise)we would be able to use only one sector and distribute the power roughly equallybetween the lower and upper floors.

3.4. Frequency Planning Issues

4 TRUs have to be planned manually but also will have to be considered in themacrocell frequency planning for interference purposes. BCCH and TCHfrequency allocations of the indoor site can be performed using WataniyaSpectrum assignment. There are, however, two constraints that have to becarefully respected :

A) Minimum 2 Channel-spacing between macro layer on the roof top and eachBCCH/TCH channel selected on the indoor sectors

B) Once the indoor channels have been assigned, these have to be includedmanually in the AFP for macrocell frequency assignment of the MSCneighbours to avoid co-channel interference.

Furthermore, handovers should never happen from indoor cells to the MSC macrolayer to avoid overloading the macro layer. The latter should be exclusivelyassigned to outdoor customers, whereas indoor users will have to use the indoorequipment resources. This can be done by forcing subscribers of the 2 indoorsectors (BSS Parameters Settings) not to handover to the macro layer resources
