Venezuela in further DTT testing
Juan Pablo Conti ©RapidTVNews | 29-10-2011 The Venezuelan government has launched a new round of transmission tests designed to optimise the process of spectrum planning for the country's future digital terrestrial television (DTT) system.
Back in 2000 Venezuela became one of Latin America's first nations to formally state its intentions to deploy a national DTT network. During the 11 years that have since elapsed, however, the country has been left behind by other regional initiatives such as those in Brazil or Argentina, where DTT transmissions are already covering a growing number of conurbations.
The new round of tests is taking place around the capital, Caracas. Specifically, the UHF airwaves are being broadcast from the Mecedores transmission site located at the Waraira Repano National Park. The main objective is to determine the most efficient transmission power level that will be required to cover Caracas.
Initially, the transmitter is being tested with an effective radiated power of 30 kW using a 10-dB gain antenna. Depending on the results obtained, engineers in charge of the project will specify the power range for the rest of the transmitters that will need to be installed around the Capital.
Once the Caracas test phase is over, similar tests will have to be carried out for each main urbanised area throughout the country. Candidate upcoming cities to receive such tests are Maracaibo, Puerto La Cruz, Barquisimeto, Mérida, San Cristóbal, Valencia and Maracay.
Like most other South American nations, Venezuela will be deploying its DTT system based on the Brazilian-Japanese ISDB-T transmission standard.
