#WirelessWednesday – What is Dali’s approach to HetNet?
“HetNet” (Heterogeneous Network) is a network consisting of various elements with different characteristics. In a telecom environment, a HetNet could be e.g. a network of cellular, cable-connected and WiFi components, or comprising of various technologies such as microwave, cellular and fiberoptic transmission links.
In the current business context, HetNet stands for a network consisting of a large macro cell providing basic coverage and capacity and an underlay of multiple smaller cells covering the traffic hotspots within the macro cell area.
Dali’s Approach
In dense HetNet environments, interference between small cells quickly becomes the limiting factor for throughput and performance. Dali’s RF Routing and digital simulcasting capabilities largely avoid inter-cell interference, while the built-in 1Gbps IP backhaul on every fiber link provides an effective traffic-offloading mechanism for hotspots. This ultimately increases user experience, network performance and provides significant cost benefits for operators. The fully software-controlled RF Routing enables service area to be configured as one or more logical cells, distributing the network capacity whenever and wherever needed; therefore, overlapping zones that can cannibalize capacity are eliminated. With Dali’s unique capabilities, mobile operators and enterprises will get the benefits of HetNet without its limitations.
