10. A method for determining a quality of a wireless data connection, comprising:
receiving a thruput of the wireless data connection, a data round trip time, a number of clicks needed to receive a predetermined data value and a packet loss percentage;
dividing the predetermined data value by the thruput of the wireless data connection to obtain a transmission time value;
multiplying the data round trip time by a number of clicks needed to receive the predetermined data value to obtain a second value;
adding the transmission time value to the second value to obtain a third value;
subtracting the packet loss percentage from one to obtain a fourth value;
dividing the third value by the fourth value to obtain a data quality index value representative of the quality of a wireless data connection; and
outputting the data quality index value.
11. The method of claim 10 , wherein the thruput of the wireless data connection, the data round trip time and the packet loss percentage are with respect to a single sector of a wireless base station.
12. The method of claim 11 further including the steps of:
determining the data quality index value for a plurality of sectors; and
summing volume weighted values of the plurality of data quality index values to determine a network data quality index value.

14. The method of claim 13 further including the steps of:
determining the data quality index value for a plurality of users; and
summing volume weighted values of the plurality of data quality index values to determine a user group data quality index value.
15. The method of claim 10 , wherein the predetermined data value is 1 megabyte.
16. The method of claim 10 , wherein the number of clicks needed to receive the predetermined data value further comprises at least one of 10 clicks for web browsing, 2 clicks for music downloading and 1 click for video downloading.
17. The method of claim 10 , wherein the packet loss percentage further comprises a percentage of packets that must be retransmitted to a receiving point.
18. The method of claim 10 , wherein the data round trip time further comprises a period of time to request and download a selected amount of data over the wireless data connection.
19. A method for determining a quality of a wireless data connection, comprising:
receiving a thruput of the wireless data connection, a data round trip time, a number of clicks needed to receive a predetermined data value and a packet loss percentage;
determining a data quality index value for the wireless data connection according to the equation:
DQI i ≈(1 MB/thruput i +Click per MB *RTT i )/(1−loss % i )
