Answer - C - You should increase the fade margin to improve the uptime or service level of a wireless link.

Key Takeaway: Fade margin is not a property of an antenna. Fade margin is based on the link power budget. The fade margin is a figure of merit for the link, as it reflects on the reliability of the connection. To improve fade margin, you should increase TPO, use higher gain transmission or reception antenna, raise the tower height, or use a more sensitive receiver. The larger the fade margin, the less likely the link will lose its connection.
