Featured Mobile Network Coverage Solution: Dali Wireless HDS
Dali Wireless’ High Density System (HDS™) provides an attractive option for operators that are looking to scale their networks and allocate wireless network coverage and capacity dynamically while containing the production cost per gigabyte transported by the RAN. This makes HDS suitable for many deployment scenarios that require dynamic capacity allocation, intelligent coverage, and intelligent interference mitigation. This business case is further enhanced with HDS’ capability to end over-provisioning and allow shared infrastructure to save significant CAPEX and OPEX.
Based on the company’s patented RF Router technology, HDS delivers the high capacity of a macro-cell, the flexible network coverage of distributed antenna systems (DAS), with the tiny footprint of a pico-cell. The foundation of HDS lies in its unique end-to-end digital RF signal processing and software configurability. Base station signal is converted to digital addressable packets, allowing routing of radio capacity from any source to any destination point within the 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.
HDS has an optical link budget sufficient for operators to deploy over a long range without signal degradation. Since HDS is technology-, vendor-, and band-agnostic, operators can now route all cellular traffic over a single fiber at a data rate of 10Gbps / 300MHz, leading to efficient data transfer and more data throughput. It’s the only solution on the market that meets the 3GPP MIMO signal requirement for delay in-balance of maximum 65ns. In addition, with the 1Gbps transparent Ethernet channel, HDS can also carry IP traffic over the same fiber and support IP appliances such as video surveillance and security camera in a plug-and-play fashion.
The HDS’s unique ability to power a multipoint-to-multipoint network is critical as data traffic varies with time and location. This feature eliminates the need to provision every destination point to the peak capacity, essentially putting an end to wireless over-provisioning and saving operators up to 30 percent in OPEX. With this capability, operators can save significant capital and operational costs and increase the utilization of valuable base station resources and finite spectrum through a virtualized RAN. RAN virtualization is a strong candidate for future RAN evolution due to its scalability and flexibility, helping to make the operator’s network future-proof.
