ESTUDIO DE COEXISTENCIA ENTRE SERVICIOS DE TDTY LTEEN LA BANDA
614-698MHZ PARAAMBIENTES TRANSFORNTERIZOS
CASO DE ESTUDIO COLOMBIA- BRASIL
Acuerdodecooperación Especial
ESCUELA-ANE0057–2016
Problemática y Justificación
• La ANE propuso en el WRC15 el uso
de la banda 614-698MHz para uso
de IMT en la región 2 (Américas)
• Colombia acordó estudiar el
coexistencia de servicios en dicha
banda con países vecinos y
presentar un modelo en la WRC19
• Los países vecinos tiene diferentes
planes de asignación espectral para
TDT e IMT.
Objetivo y Etapas
GENERAL
• Definir una metodología
para el estudio de la
coexistencia de las
señales TDT y LTE en
ambientes
transfronterizos para la
banda de 614 a 698MHz,
tomando como base el
caso Colombia-Brasil.
