A car’s onboard navigation system receives a signal that an accident has occurred a short distance ahead and alerts the driver while proposing an alternate route. Which aspect of a 5G network helps in this situation?
- virtual reality
- higher connection density
- reduced latency
- increased bandwidth
- I don’t know this yet.
The correct answer and explanation is:
Correct Answer: Reduced Latency
Explanation:
In this scenario, the car’s onboard navigation system quickly receives information about an accident ahead and provides an alternative route. The most critical factor that enables this functionality in a 5G network is reduced latency.
Latency refers to the time it takes for data to travel from one point to another in a network. In previous generations like 4G, latency could be around 50 milliseconds (ms) or more, but with 5G, latency is reduced to as low as 1 millisecond. This near-instantaneous response time is crucial for real-time applications such as connected vehicles, autonomous driving, and smart transportation systems.
Why Reduced Latency Matters in This Case:
- Real-Time Data Transmission: The accident information must be transmitted and processed in real time to ensure that the driver can take immediate action. Delays in receiving such updates could lead to further congestion or even accidents.
- Vehicle-to-Everything (V2X) Communication: 5G enables V2X technology, where cars communicate with other vehicles, infrastructure (such as traffic signals), and networks. Reduced latency ensures that accident alerts and rerouting suggestions are provided without delay.
- Safer Driving Decisions: A driver needs timely and accurate navigation updates to make the best decision about taking an alternate route. If the system reacts too slowly, the driver may already be stuck in traffic.
- Efficiency in Smart Transportation: Reduced latency enables a smoother traffic management system, optimizing road usage and reducing congestion in smart cities.
Conclusion:
The ability of the 5G network to provide ultra-low latency is what makes real-time accident alerts and route suggestions possible. This advancement enhances both safety and efficiency in transportation.
