What is the lifespan of a beacon?

Could you elaborate on the expected lifespan of a beacon in the context of cryptocurrency or blockchain technology? Are we referring to hardware beacons used for tracking or communication, or perhaps a metaphorical beacon in terms of network stability or signal strength? If it's the former, factors like battery life, environmental conditions, and maintenance practices would likely influence its longevity. If the latter, the lifespan may be dependent on the robustness and scalability of the underlying blockchain infrastructure. Clarifying the specific context would help provide a more accurate answer.
