ICS TELECOM EV PROVIDES THE MOST COMPREHENSIVE SET OF TOOLS FOR THE DESIGN OF BROADCAST NETWORKS

Overview

Broadcast


Broadcast networks must serve the maximum number of people at minimum cost.
ICS telecom EV gives operators the tools to achieve that.


ICS telecom EV ensures efficiency and cost-effectiveness at all stages of the network’s life:



  • Coverage planning

  • Interference calculation

  • Population analysis

  • ITU procedures

  • Automated site planning

  • Automated site optimization

  • Automated frequency planning

  • SFN network optimization

  • Reforming frequency band and inter system coexistence (LTE, ILS, White spaces etc.)

  • Transport (Microwave) planning


ICS telecom EV facilitates the design of analog and digital broadcast networks in a number of standards:



  • DVB-T/T2

  • DVB-S/S2

  • ISDB-T

  • DTMB

  • MMDS

  • T-DAB/DMB

  • FM mono/stereo


Case studies

Switching from analogue to digital broadcasting



Challenge


Switching from analog to digital broadcasting maximizes use of existing infrastructure and minimizes capital expenditure.


Solution


HTZ telecom edition's “Select stations” function identifies the sites which cover the largest area or population thereby minimizing the number of sites needed to provide the service. In conjunction with the “power optimization” function and other tools, operators are able to assess potential savings by reducing transmitter power.

Population analysis



Challenge


Population analysis starts with distribution modelling. ICS telecom EV models population in several ways from lists, vectors and rasters to provide maximum accuracy.


Solution


HTZ population reports cover:



  • Percent and total number of the covered population by network

  • Total number of the covered population for each station

  • Settlements in the service area for each station

  • Percent of the covered population in each settlement

Coexistence with mobile and other services



Challenge


The re-use of former broadcast spectrum by mobile operators creates potential interference issues for broadcasters.


Solution


ICS telecom EV calculates potential interference in a variety of ways. For standard cases of intersystem interference there are special functions and algorithms (for instance ITU SM1009 recommendation for broadcasts vs ILS) but sometimes users need more general tools to analyze interference. In this case, HTZ defines spectrum masks for the transmitter signal and rejection filters of the receiver and calculates interference based on spectrum convolution. Interference can be analyzed as broadcast Tx vs mobile Rx, mobile Tx vs broadcast Rx, interference coverage, P2P interference.
