WSPD enhances situational awareness during six day city-wide festival with Dejero mission-critical connectivity

WSPD enhances situational awareness during six day city-wide festival with Dejero
Dejero, an innovator in mission-critical connectivity solutions proven to deliver real-time data and high-quality live video over IP for situational awareness, recently supplied its GateWay network aggregation device to Winston-Salem Police Department (WSPD) for critical connectivity during the International Black Theatre Festival (IBTF). Powered by Dejero Smart Blending Technology™, GateWay is certified by multiple nationwide US wireless communications networks built for priority-use of first responders and the public safety community. Smart Blending Technology combines connectivity from diverse cellular and other IP network providers, including LEO, MEO and GEO satellites creating a virtual ‘network of networks’ to provide access to a far greater coverage area than any single provider can deliver. Easily transported, GateWay can be set up in a matter of minutes, making it ideal for on-location events.

The Evolution of Non-Terrestrial Networks: From Experimental Beginnings to Global Connectivity

The Evolution of Non-Terrestrial Networks: From Experimental Beginnings to Global Connectivity
Non-terrestrial networks (NTNs) have evolved from experimental satellite systems to integral components of global connectivity. The transition from geostationary satellites to low Earth orbit constellations has significantly enhanced mobile broadband services. With the adoption of 3GPP standards, NTNs now seamlessly integrate with terrestrial networks, providing expanded coverage and new opportunities, especially in underserved areas. This evolution is set to transform telecommunications by enabling innovative applications across various sectors.
