1. A method comprising:
- creating a first measurement of signal quality, SQ(n), of a signal received from a wireless terminal;
transmitting a first message to said wireless terminal to direct a user of said wireless terminal to move said wireless terminal in one direction when said first measurement of signal quality, SQ(n), is unsatisfactory;
creating a second measurement of signal quality, SQ(n+1), of said signal received from said wireless terminal after transmitting said first message; and
transmitting a second message to said wireless terminal to direct said user of said wireless terminal to move said wireless terminal further in said one direction when said second measurement of signal quality, SQ(n+1), is better than said first measurement of signal quality, SQ(n), and said second measurement of signal quality, SQ(n+1), is still unsatisfactory.

Abstract
A technique for preventing the user of a wireless terminal from carrying a wireless terminal into the umbra of a fade is disclosed. In particular, some embodiments of the present invention notify the user that the user is in danger of entering the umbra and assist the user in navigating from the fade. An illustrative embodiment of the present invention comprises: creating a first measurement of signal quality, SQ(n), of a signal received from a wireless terminal; and, when the first measurement of signal quality, SQ(n), is unsatisfactory, transmitting a first message to the wireless terminal to direct a user of the wireless terminal to move the wireless terminal in one direction.
