Chinese tech company ZTE has implemented dynamic spectrum sharing (DSS) solution for transition to fifth generation network without any disruption in the existing second, third and fourth generation services. ‘ZTE's SuperDSS’ was implemented in South Africa, the first of its kind in the region, the company said in a press release on Sunday. Leveraging tri-signal radio access technology, the SuperDSS field trial was implemented on 2.1 gigahertz spectrum within 15-megahertz bandwidth, compared with the current static spectrum allocation solution of third and fourth generation’s network. According to the trial results, the company said the SuperDSS solution allowed the fast introduction of 5G on the 2.1 ghz spectrum, and simultaneously increased the 4G single user average throughput by 39.85 percent, without negatively affecting the existing 3G and 4G major KPIs and user experiences. For a long time, ZTE has been dedicated to investigating the feasibility of spectrum sharing solutions at various stages of network development. ZTE's SuperDSS is a design-oriented 5G evolution networking solution. It helps operators build a lean multi-mode and multi-service network that supports 5G safeguarding existing investments. The DSS among 3G to 5G network helps maximise spectrum utilisation in the network evolution process, with more bandwidth being allocated for LTE and NR as UMTS bandwidth changes on demand apart from traditional voice service.

In a major breakthrough, researchers in Bangladesh have found that an existing medicine called eltrombopag -- used to treat chronic immune thrombocytopenia or chronic hepatitis C infection -- could be repurposed to create the first drug treatment for the deadly dengue fever.
