# Harnessing the Potential of Emerging Technologies to Break Down Barriers in Tactical Communications
## 3 Emerging Technologies as Potential Candidates: Overview
If necessary, it can also alert a medical response team at a base hospital. Soldiers are equipped with specialized helmets featuring integrated monitoring sensors designed to detect potential concussions and other brain traumas. The deployment of small, intelligent telemetric health monitoring devices and medical care equipment is becoming increasingly prevalent in combat scenarios. This allows for unmanned first aid to be administered promptly to soldiers in need. 4. **Military training**: IoT technology can find application in military training through the use of virtual simulations depicting various combat scenarios. With virtual reality, scenarios can be accurately replicated using sensors that track the position and physiological states of soldiers during training. The data gathered by these sensors can then be analyzed for later evaluation. Similarly, MIoT can also be seen as IoT in the battlefield, the _Internet of battlefield things_ (IoBT) [29; 30]. * **Tactical internet**: It is a fluid network of very different subnets, which have various characteristics but must keep communication links without a fixed infrastructure [31]. Hence, tactical internet in tactical networks seeks to enhance the efforts of C4 ISR with Internet-based applications. Military organizations use this type of network to provide communications services that connect strategic decision makers with commanders deployed at headquarters and extend that connection to all soldiers and vehicles. The most fundamental feature differentiating the tactical internet from a standard internet is core mobility; that is, you cannot rely on any other elements of the tactical internet to be present. Therefore, it must be able to adapt to situations where the paths between networks are constantly changing. The ideal tactical internet communication solution is to connect the low bandwidth tactic to the higher bandwidth core of the network, consolidating must-have network features into an easy-to-manage network device designed for your use in tactical vehicles with space constraints. * **Tactile internet**: It is a technology for improving accuracy in human-machine and machine-machine interaction [32]. Key examples can be found in robotics, virtual reality, augmented reality, and the military, among others. The advantages of the tactile internet are diverse, such as high availability and security, ultra-fast reaction times, and high reliability. This offers low enough latency to build interactive systems in real time. In principle, all our human senses can interact with machines, but among the senses, visual-tactile interaction between humans is becoming more and more important, especially due to the proliferation of smartphones. For all these reasons, the tactile internet adds a new dimension to human-machine interaction by allowing tactile and haptic sensations to interact with their environment in real time. A tactile internet application is virtual reality. Low-latency communications enable \"shared haptic virtual environments\", where multiple users are physically coupled through a virtual reality simulation to perform tasks that require fine motor skills. Another application is augmented reality. The tactile internet reaches new frontiers in assistance systems. Now, it is possible to virtually extend the field of vision in real time to achieve the concept of \"seeing what others are not able to see\". * **Wearables**: These devices can operate at higher speeds with fewer interruptions and cover larger areas. This technology was originally proposed with health objectives in mind for medical applications [33], which can also be extended to military applications, such as assessing the soldier's health. * **Unmanned aerial vehicles (UAVs)**: Commonly referred to as drones, these are aircraft that are guided autonomously, by remote control or both, and that carry some combination of sensors, receivers, and transmitters. They are used for strategic and operational reconnaissance for battlefield surveillance.
