#### 3.2.4 Network Technical Requirements  
When it comes to medical scenarios, network requirements turn out to be higher and more critical than other types of scenarios that also require massive data transmission, such as agriculture and road traffic management [34]. Uninterrupted communication is needed to connect patients, doctors, and emergency services, generating diverse requirements, which result in higher performance from a technical point of view.  
Table 4 shows the classification of the articles according to the technical requirements presented in each of the studies.  
As seen in Table 4, the authors pay much attention to system latency. This is because it is one of the key requirements for end-to-end communication in mobile health [17], since it involves the time needed for the acquisition, emission, reception, preprocessing, and display of the data at the endpoint. In addition, it is vital in the transmission of high-definition information, such as the transmission of medical multimedia content in ambulance scenarios [31]. Similarly, in remote-surgery systems, ultra-low latency allows the surgeon to have haptic feedback [30]; that is, despite being located miles from the patient,

the specialist can feel the person's tissues through the robotic arm just as in conventional surgeries. On the other hand, with ultra-low latency, machine-machine (M2M) and device-device (D2D) communications, and even human-machine interactions (H2M) [29] can be carried out, making possible the development of telesurgery, telessistance, remote monitoring, and surveillance with drones.  
Likewise, capacity is another requirement shown by a large number of studies, which address issues such as system bandwidth, which should guarantee quality of service (QoS) to patients [21; 25]. To a lesser extent, data speed is also considered, since it can contribute to the fast and reliable transmission of medical files and multimedia information successfully [26; 31].  
It should be noted that all the works initially identified as implementations detail the specifications and technical details of their systems. However, the proposals, prototypes, and studies under development do not always expose these characteristics. This is because works of this nature are not being implemented due to the fact that the 5G network is not yet available in most countries. Nevertheless, it is possible to perform an analysis because they have theoretical foundations and relevant information related to the variables of analysis.
