Question

question 3 of 15 using directional antennas, implementing encryption, and signal filtering are all techniques that can do which of the following? select the correct response. to determine the frequency of the transmitted signal improve the reliability of the data link create a beyond line - of - sight data link minimize free space path loss

Explanation:

Directional antennas focus signal energy, encryption protects data integrity and confidentiality, and signal - filtering reduces noise. All these help in improving the reliability of the data link. Determining signal frequency is not their purpose. Creating a beyond - line - of - sight data link is not directly related to these techniques. Minimizing free - space path loss is not the main function of these methods.

Answer:

B. Improve the reliability of the data link
