This comparison is good for saying that the current cell is below an absolute threshold and the new cell is above a threshold. This would mean that the current cell is not good enough and the new one is good, which is a good reason to do a hard handover in either technology. Event B2 - Serving becomes worse than threshold1 and inter RAT neighbor becomes better than threshold2. This comparison is good for saying that the current cell is below an absolute threshold and the new cell on a different technology is above a threshold.

Enjoy 3G 4G!!!!!!!!!!!! Measurement report 3G Two types of Measurement reporting is possible in 3G 1. Periodic 2. Event triggered Measurement reporting parameters for both Periodic and Event triggered are set through system information. Following are the different measurement reporting that UE can Perform:- 1.
Event 2c: The estimated quality of a non-used frequency is above a certain threshold Event 2d: The estimated quality of the currently used frequency is below a certain threshold Event 2e: The estimated quality of a non-used frequency is below a certain threshold Event 2f: The estimated quality of the currently used frequency is above a certain threshold 3. Event 3b: The estimated quality of other system is below a certain threshold Event 3c: The estimated quality of other system is above a certain threshold Event 3d: Change of best cell in other system 4.
Event A1 Serving becomes better than threshold 2. Event A2 Serving becomes worse than threshold 3. Event A3 Neighbor becomes offset better than serving 4. Event A4 Neighbor becomes better than threshold 5. Event A5 Serving becomes worse than threshold1 and neighbor becomes better than threshold2 6. Event A2 - Serving becomes worse than threshold e2d - The estimated quality of the currently used frequency is below a certain threshold In LTE this may be used to start looking for a cell on a different frequency or technology, as e2d is used in UMTS.
Event A4 - Neighbor becomes better than threshold e1e - A Primary CPICH becomes better than an absolute threshold Event A5 - Serving becomes worse than threshold1 and neighbor becomes better than threshold2 e2b - The estimated quality of the currently used frequency is below a certain threshold and the estimated quality of a non-used frequency is above a certain threshold This comparison is good for saying that the current cell is below an absolute threshold and the new cell is above a threshold.
Event B1 - Inter RAT neighbor becomes better than threshold e3c - The estimated quality of other system is above a certain threshold Event B2 - Serving becomes worse than threshold1 and inter RAT neighbor becomes better than threshold2 e3a - The estimated quality of the currently used UTRAN frequency is below a certain threshold and the estimated quality of the other system is above a certain threshold This comparison is good for saying that the current cell is below an absolute threshold and the new cell on a different technology is above a threshold.

The slot timing of the cell can be obtained by receiving the primary synchronization channel P-SCH and detecting peaks in the output of a filter that is matched to this universal synchronization code.
The slot synchronization takes advantage of the fact that the P-SCH is only sent during the first chips of each slot. Adobe Premiere Pro Bible. Dreamweaver MX Bible. JavaScript Bible, Gold Edition. Oracle 9iAS Portal Bible.

Radio technology is not used, and hence efficiency cannot be offered in the system as much as that of WCDMA.
Radio technology is used in the system, and hence communication is done between two devices as an interface is used in the system. This makes the system more efficient and does not make any issues while transferring data. This is one of the popular air interfaces used in mobile devices.
This is an upgrading of CDMA where very less speed is used as per the standard.
