Deutsche Telekom and Ericsson exceed the 100 Gbps on a microwave link

15/05/2019

Deutsche Telekom and Ericsson exceed the 100 Gbps on a microwave link El enlace de microondas a una distancia de m s de 1,5 km alcanza un rendimiento diez veces superior al de las soluciones comerciales actuales.

Ericsson and German Telekom han alcanzado una velocidad de transmisi n de datos sin precedentes al superar los 100 Gbps en un enlace de prueba de microondas de m s de 1,5 km.

Realizado en el Deutsche Telekom Service Center de Atenas, el proyecto de innovaci n conjunta representa un gran avance t cnico, ya que alcanza velocidades de procesamiento m s de diez veces superiores a las de las soluciones comerciales actuales sobre un espectro de ondas milim tricas de 70/80 GHz similares.

Alex Jinsung Choi, vicepresidente senior de estrategia e innovaci n tecnol gica de Deutsche Telekom, afirma que se necesitar n soluciones avanzadas de backhaul para soportar un alto rendimiento de datos y una mejor experiencia del cliente en la era de los 5G. Este hito confirma la viabilidad del espectro de microondas sobre ondas milim tricas como una importante extensi n de nuestra cartera de opciones de transporte de alta capacidad y alto rendimiento para la era 5G. Adem s, representa una soluci n que cambia el juego para las futuras capacidades de fronthauling .

Per Narvinger, director del rea de redes de productos de Ericsson, afirma que esta prueba significa el establecimiento exitoso de capacidades reales de fibra en el aire mediante el uso de microondas. Esto significa que el microondas ser a n m s relevante para los proveedores de servicios de comunicaciones en la creaci n de redes redundantes como respaldo para la fibra, o como una forma de cerrar un anillo de fibra cuando la fibra no es una soluci n viable. Con estas altas capacidades, el microondas se establece como una tecnolog a de transporte clave, capaz de cumplir con los requisitos de rendimiento de 5G .

Adem s de confirmar el potencial de la tecnolog a de microondas en el espectro de ondas milim tricas (70/80 GHz y m s) como una soluci n de 5G y m s all de las soluciones de front-haul y backhaul, el ensayo demostr la importancia de aplicar t cnicas espectrales eficientes, como MIMO (multiple input, multiple output) en las tecnolog as de backhaul inal mbricas para hacer frente a las futuras demandas de acceso radioel ctrico 5G.

Equipamiento t cnico Los principales avances tecnol gicos incluyeron un MIMO con l nea de visi n de 8 8 con configuraci n de cancelaci n de interferencia de polarizaci n cruzada utilizando radios comerciales MINI-LINK 6352 y un ancho de banda de canal de 2,5 GHz en la banda E (70/80 GHz) capaz de transmitir ocho flujos de datos independientes a trav s del trayecto de radio. Esto corresponde a una eficiencia de espectro revolucionaria de 55,2 bps/Hz en el pico.

Durante la prueba, las mediciones de las tasas de transmisi n se mantuvieron consistentemente por encima de los 100 Gbps, con una disponibilidad de grado de telecomunicaci n (superior al 99,995 por ciento), con tasas m ximas que alcanzaron los 140 Gbps.

A finales de 2018, Ericsson y Deutsche Telekom rompieron la barrera de los 40 Gbps con equipos comerciales, incluyendo la soluci n MINI-LINK 6352 de Ericsson, que actualmente proporciona una capacidad de 10 Gbps en un canal de 2000 MHz. Para aumentar el rendimiento m s de 10 veces, esta prueba utiliz un canal de 2500MHz y equipo de procesamiento precomercial de banda base y MIMO, adem s de radios MINI-LINK 6352.
