To achieve the required improvement, a number of measures were taken. A number of thresholds
were introduced to determine whether a handoff is really necessary. These are based on elements
such as the total pilot channel energy that is coherently demodulated. By utilizing the thresholds,
the number of handoffs is reduced while still ensuring that handoffs are implemented when they
are really required. By achieving a reduction in the number of handoffs that are undertaken, the
system capacity that is available for real traffic is incre ased.
CDMA2000 1xEV-DV
While CDMA2000 1X was particu larly successful, and the data rates offered did fall into some
of the 3G classi fications, it was nonetheless not the final evolution for 1X. Higher data rates
