Communication pathway supporting an advanced split microwave backhaul architecture

摘要

An advanced split ODU architecture is provided. The advanced architecture includes an indoor communication unit including a digital modem assembly configured to modulate and demodulate digital data, and also includes a digital interface module configured to transmit and/or receive the digital data, over a digital communication pathway, between the indoor communication unit and an external outdoor communication unit. The advanced architecture further includes an outdoor communication unit having a digital interface module configured to transmit and/or receive the digital data, over the digital communication pathway, between the outdoor communication unit and an external indoor communication unit, and also includes a digital to analog converter configured to convert the digital data to analog data and an analog to digital converter configured to convert the analog data to the digital data, and further includes an RF module configured to convert the analog data between a baseband and a radio frequency.
