A collection of AeBS is called a FANET (Flying Ad-hoc Network). In a FANET, AeBS communicate within each other using the 802.11p protocol, which is used in vehicular communications

Advantages and Limitations

AdvantagesLimitations
AeBS can be deployed ad hoc - They can be readied on demand. This is useful when covering areas where internet access is lost due to emergencies and in situations where disposable internet is requiredThere’s generally not enough energy to power an AeBS for long durations of time. There’s always a tradeoff between endurance and power
AeBS are more immune to interference due to having a LoS. This is an important advantage to make use of with 5G networks that use mm-wave technology that requires good LoSThe deployment of AeBS may breach data security and privacy because it opens a new point of attack or data interception
Broader internet coverage is provided across wider ground ranges
