Dali Wireless Debuts Virtual RAN Solution to Enable Intelligent Wireless Coverage

0

Dali Wireless, Inc., a global provider of the advanced all-digital RF Router, has unveiled High Density System (HDS). This platform makes it suitable for many operator scenarios that require dynamic capacity allocation, intelligent coverage, and intelligent interference mitigation. It can also serve as an end-to-end digital Distributed Antenna System (DAS).

Based on the RF Router technology, HDS delivers the high capacity of a macro-cell, the flexible coverage of DAS with the tiny footprint of a pico-cell without traditional interference challenges. HDS is the only digital-to-the-edge “fiber-to-antenna” Radio Distribution System on the market.

It is technology-, vendor-, and band-agnostic. HDS supports up to 10Gbps / 300MHz over a single fiber, leading to efficient data transfer and more data throughput. In addition, it is the only solution on the market that meets the 3GPP MIMO signal requirement for delay in-balance of maximum 65ns. With Dali’s patented dynamic capacity allocation and digital RF Router technology, it has an optical link budget sufficient for operators to deploy over a long range, as high as 40km, without signal degradation. This results in less noise interference and less equipment required.

As mobile connectivity becomes ubiquitous, coverage is also needed in rural areas. However, rural areas tend to have low density of users and business economics sometimes do not justify a separate deployment for the rural areas.

With HDS, operators can now install a solution in a major city and simultaneously route the capacity to the nearby rural area where coverage is needed. Operators will have the flexibility to allocate resources dynamically to best utilize the scarce spectrum and provide a truly future-proof solution.

In a typical urban deployment, operators need to support the wireless peak load for each individual building where mobile usage and density are high. With HDS, capacity over-provisioning is no longer an issue. HDS can dynamically pool capacity together, and route it to where and when capacity is needed.

HDS transforms any radio frequency signals from base stations into IP, CPRI, or IP/CPRI-like packets to allow “any-to-any RF routing” within a software-defined virtualized radio distribution network. With this revolutionary approach, operators can address the challenges and limitations of traditional DAS including link budget, capacity over-provisioning, interference and handovers.

“HDS is uniquely different from both conventional analog and digital systems. HDS is built upon a decade worth of patented digital signal processing, proprietary RF power amplifiers and advanced networking technologies; rather than incrementally building on current DAS concepts,” said Albert Lee, CEO of Dali Wireless. “This puts Dali’s customers in a position to maximize ROIs in this rapidly evolving telecommunications ecosystem. HDS is a differentiator for our customers to monetize trends now and in the future.”
