How do Link 11 and Link 11B primarily differ?

The primary difference between Link 11 and Link 11B lies in their mode of communication. Link 11 operates using a network that primarily relies on half-duplex communication, meaning that data can only be transmitted in one direction at a time. This approach limits the efficiency and speed of data exchanges in the network.

On the other hand, Link 11B enhances the capabilities of its predecessor by supporting a more flexible and efficient communication mode. Link 11B incorporates full-duplex communication, which allows data to be sent and received simultaneously. This results in improved data transfer rates and the ability to engage in more complex operations.

While other factors such as encryption levels, compatibility with Link 16, and throughput capacity are important in understanding the overall functionality of these systems, the fundamental distinction comes from how they manage data transmission, making the mode of communication the key differentiator between the two.
