Core to Dali’s SDN Radio Router™ technology is its “end-to-end” digital RF signal processing. Analog RF from the base station is converted to digital signals in the signal processing module and the signal remains digital right up to the antenna location. Digital signals are tagged with an address which allows signals to be sent from any source to any destination point within the radio distribution network.
How is that different from other hybrid-digital systems with fiber optic transmission? Digital transmission only allows a simple point-to-point network – always the same source, and always the same destination, as the network is hardwired. With digital RF signal processing, an intelligent logical layer supersedes the hardwired physical network. Irrespective of the underlying physical transport network, a logical network is formed that enables RF signals to travel from any source to any destination point – a multipoint-to-multipoint network.
