Solutions for transformation of the existing nationwide analogue network into DVB-T SFN networks

02.2010 www.kvant-efir.com.ua

Introduction • The project development and its rapid installation are crucial for the successful fulfillment of the “Geneva-2006” (GE-06) agreement and ASO to take place before 17 June 2015. As it is well known that analogue TV spectrum will not be protected after this date, It is very important to find an optimal solution in project development, which will further help to decrease the cost and accelerate DVB-T network roll-out. • The rapid DVB – T network and services roll-out with CAPEX minimization is of paramount importance to the countries which are in initial stage of DVB-T network creation, especially to the ones in Central and Eastern Europe, and Asia. • The presentation describes the implemented methodology that is intended for overcoming the problems arising due to the transformation of the existing nationwide network for analogue broadcasting into many DVB-T single-frequency networks (SFNs). 02.2010

• The methodology aims at adjusting the parameters of the existing transmitting stations (TS) (built years ago for analogue broadcast networks) to the present-day (SFN) spectrum and network planning. • This methodology depicts the calculations of the effective radiated power (ERP) of transmitters, antenna patterns for each TX site in each of SFN zones in compliance with such requirements as frequency allotments in the GE-06 plan entries, transmitter modes, reception conditions etc. • Further is described the preparation (after the frequency assignment) of the technical project template for achieving the best reception conditions in each of SFN zones. • The presentation also gives an insight into the accurate technical specifications for each TX site in each of SFN zones. • Finally, the latest results of the practical implementation of the methodology for the project execution in Odessa region of Ukraine are introduced. 02.2010

Ukraine Location of the existing ~500 masts and allocation of 79 SFN zones according to the GE-06 plan entries

Locations of the towers for analogue MFN networks do not directly conform to the task of creating many SFNs. Some of the towers are located near the border of 2-3 SFNs.

02.2010

Comparison between the ideal typical SFN zone and real SFN zone 74 There are two ways of SFN network planning: - Using an ideal typical SFN network for providing portable indoor reception; - Using the existing masts built for analogue MFN networks which do not conform to the task of creating the ideal SFN network for portable reception. Use of the existing masts is compliant with the tasks to be undertaken for the transition period up to ASO. Location of the masts for analogue TV broadcasting in SFN zone #74, Odessa region, Ukraine

Problems and compromise solutions • The transition period, (up to the analogue switch-off, ASO), the simultaneous DVB-T and analogue broadcasting along with the use of new transmitting stations with DVB-T transmitters installed in single frequency networks (SFN) are complicated by interference to analogue TV receivers, located at the periphery of each SFN-zone; • Compromise for the transition period; • Maximal use of all the masts in operation for analogue broadcasting in order to minimize CAPEX and to accelerate DVB-T network roll-out; • Installing of a little quantity of low-power SF gap fillers and transmitters for DVB-T synchronous broadcasting in the areas with poor reception.

02.2010

31

Template of the DVB-T SFN network project development Step 1 • At the request of DVB-T service provider or regulatory bodies, the broadcast network operator or the project executor calculates the preliminary antenna patterns for each TX site in each of SFN zones in accordance with the location and parameters of the transmitting masts: height and geographical coordinates. The required reception conditions (fixed, portable and others) and transmitter mode (64QAM ¾ GI ¼ is determined by the regulators in Ukraine for the transition period) are also taken into account.

Step 2 consists in the following:

on the basis of the calculated and offered to the Frequency Regulator results of antenna patterns and ERP (for providing the maximum coverage), geographical coordinates of masts, antenna height and transmitter mode (64QAM ¾ GI ¼ has been chosen for the transition period in Ukraine), the Frequency Regulator specifies the conditions of the use of radio frequency resource including the maximum possible ERP, antenna patterns and antenna height for each TX site. 02.2010

Initial stage of DVB-T network roll-out is in need of a different approach; This approach depends on the peculiarities of the present-day analogue TV networks, the situation with the existing TV services market (e.g. the quantity of nationwide and regional TV programs, situation with the frequency resource and peculiarities of the existing analogue networks etc); After the transition period this approach has to be revised; DVB-T network roll-out for transition period (up to ASO) needs compromise solutions; note the technical problems arising during simultaneous DVB-T and analogue broadcasting (e.g. the interference to analogue TV receivers from new TX sites with DVB-T transmitters); Compromise for the transition period; Maximal use of all the masts in operation for analogue broadcasting in order to protect analogue TV receivers from interference, minimize CAPEX / OPEX, accelerate DVB-T network roll-out; Installing of a little quantity of low-power SF gap fillers in the areas with poor reception; The offered methodology allows cutting down CAPEX considerably for the transition period.
