In Ecuador, electromagnetic spectrum is a limited resource. Terrestrial Digital
Television Transition Master Plan in Ecuador mentions that terrestrial digital
television broadcasting (TDT) uses band UHF, and TDT transmission by using VHF
band is available for ISDB-T norm advances. Moreover, Terrestrial Digital
Television Broadcasting Service Technical Norm (RESOLUTION ARCOTEL-2015-
0301), it has information about UHF band frequencies and canalization. It has made
the transmission station design, UHF band coverage simulation and VHF band
coverage simulation through ICS TELECOM software. Channel Auxiliary
transmission tests were done, it was verified 204 bits channel auxiliary distribution
inside zero segment, that is part of the of the digital video transmission type 13
segments. It has identified the main natural disasters identified were earthquakes,
landslides, and volcanic eruptions at Metropolitan District of Quito. The comparison
between UHF band coverage and VHF band coverage, it shows that UHF band is the
best with 19%. The comparison between ISDB-TMM standard and ISDB-TB
standard, it shows that ISDB-TB standard is the best. UHF band design was chosen
because of the economic viability when the VAN value is $7.404.36 and the TIR
value is 17.65% to recover initial investment in one year. |
