## 2 A2S Integrated MIoT
### A2S Integrated Technology  
In an A2S integrated network, the communication equipment built by UAVs is used as the ABS, which has the characteristics of being low cost, easy to deploy, and being capable of on-demand deployment, and is widely used in military rescue, emergency communication, commercial aviation, and other fields. An ABS is a device used to provide wireless communication services, usually installed on an aircraft or other aerial platforms. An ABS usually consists of an antenna, a transmission device, a frequency converter, a processor, and a communication interface [77]. Its main function is to connect mobile communication devices (such as mobile phones) with ground BS or SC networks, allowing users to maintain communication connections during flight. The following introduces the categories of A2S BSs, their applications in various fields, and the role and advantages of ABSs in MIoT [78]. 1. Classification: * Mobile communication BS: This is the most common type of ABS used to provide mobile communication services. It connects the aircraft's mobile communications equipment with ground BS or SC networks, enabling passengers and crew to make voice calls, send text messages, and use the internet during flight, among other things [79]. * Other dedicated ABSs: In addition to mobile communication BSs, there are also some ABSs specifically designed for specific purposes. For example, military aircraft may be equipped with military communication BSs for military command and control communications; public safety BSs on aircraft may be used for emergency communications and rescue operations [80]. * Satellite communication BS: This BS provides air communication connection through a satellite network. SC installs satellite dishes and terminal equipment \begin{table}

This BS enables two-way communication between the drone and the operator, and supports DT and sensor information sharing [82]. 2. Application of ABSs in various fields: * Commercial aviation: ABSs play an important role in commercial aviation. They enable passengers to maintain mobile phone signals during the flight, make voice calls, send text messages, and use the internet. This provides a better passenger experience and communication connectivity, while also providing value-added communication services for airlines. * Military and security applications: ABSs play a key role in the military and security fields.
