Estas redes IP pueden ser Ethernet+Ethernet, Ethernet+3G o 3G+3G. Tambi n es posible usar conectividad 4G donde est disponible.

La posibilidad de combinar Ethernet y 3G/4G permite reforzar conexiones IP STL existentes de una manera muy econ mica ya que no ser a necesario construir ninguna infrastructura adicional.
Este protocolo tambi n resulta muy interesante en aplicaciones port tiles ya que hace posible establecer comunicaciones muy fiables usando dos conexiones 3G/4G de diferentes proveedores.

Ha sido dise ado teniendo en mente la transmisi n de conversaciones de voz y m sica a trav s de Internet. El algoritmo ha sido estandarizado por el Internet Engineering Task Force (IETF) en la RFC 6716.
Prodys ha decidido completar su amplio cat logo de algoritmos de codificaci n a adiendo Opus a sus equipos, teniendo en cuenta su excelente funcionamiento en la codificaci n de voz a reg menes binarios muy bajos.
Por ltimo, destacar que coincidiendo con la la celebraci n del IBC, Prodys va a poner en disposici n de sus clientes una nueva versi n de firmware para sus equipos de la familia ProntoNet.
Esta nueva versi n incluye algunas importantes mejoras como Solidstream, un m dem 4G para contribuciones inal mbricas desde los c decs port tiles Nomada W y IPXL y una interesante soluci n de emergencia que permite conmutar la salida de audio por la reproducci n de un fichero grabado en un dispositivo de memoria USB.
