What are potential drawbacks or limitations of relying heavily on satellite-backhaul data?

While relying on satellite-backhaul data offers several advantages like extended coverage range and connectivity flexibility for EIH-based systems operating across vast geographical regions or during terrestrial infrastructure failures due to disasters; there are also some potential drawbacks:

Latency Issues: Satellite communications introduce inherent latency due to signal propagation over long distances between Earth stations and satellites. This latency may affect real-time control applications that require immediate responses.

Bandwidth Limitations: Satellite links typically have limited bandwidth compared to terrestrial networks. High-resolution sensor data transmission may be constrained by these limitations leading to delays or reduced quality of service.

Cost Considerations: Utilizing satellite services often incurs high costs associated with leasing transponder space on satellites which might not be feasible for all applications especially those with budget constraints.

Vulnerability: Satellites are susceptible to external factors such as weather conditions (e.g., heavy rain affecting signal strength), solar flares disrupting signals causing intermittent connectivity issues impacting system reliability.

Regulatory Compliance: Compliance with international regulations governing satellite communications adds complexity regarding licensing requirements which must be adhered to when using satellite backhauls extensively.

Security Concerns: Data transmitted via satellites may face security risks including interception threats making it essential to implement robust encryption protocols safeguarding sensitive information being relayed through these channels.
