Tethered drones have long hovering times and stable suspension. In addition to providing aerial lighting, they can be equipped with self-organizing network radios to form a stable communication link with multiple ground nodes, achieving wireless signal coverage between the operational area and the command center, ensuring real-time video and voice transmission. Their roles are significant: … Read more
In many emergency scenarios, wireless video transmission devices and broadband self-organizing network devices are frequently used. Both types of equipment operate on-site and utilize wireless network technology to achieve information transmission. Given the prevalence of video applications today, where the primary data transmitted is video, many people are unclear about the differences between these two … Read more
In emergency situations where communication is disrupted, high-throughput satellite internet machines (portable satellite stations) paired with drones can transmit aerial footage from the emergency site back to the command center via satellite links in a timely manner. This solves the problem of returning high-definition video when mobile internet is rendered ineffective during such disruptions. However, … Read more
Intelligent Wireless, Internet of Everything When disasters such as earthquakes and floods cause widespread failure of operator base stations, the establishment of temporary base stations often takes hours or even days. During this period of “communication blackout”, wireless broadband self-organizing network technology is becoming the “invisible backbone” supporting rescue command, achieving the core goal of … Read more
Intelligent Wireless, Internet of Everything When the thick smoke from a chemical plant carries toxic gases, and high-temperature pipelines are at risk of explosion, the noise and intermittent commands from traditional walkie-talkies have been the biggest pain points for rescue command. Now, wireless broadband self-organizing network technology is becoming the “key player” in solving communication … Read more
Breaking Communication Barriers: MIMO Self-Organizing Networks Pave the Way for Future Emergency Solutions!
