Things to remember for 4G NETWORK PLANNING

• What is 4g Network and evolution of 4g

If you are a greenfield or emerging operator aiming at building a competitive Broadband Wireless Access Network (such as, for example, WiMAX and LTE), you should not make the mistake of underestimating the effort you need to put in place. This is and will remain a complex undertaking, especially if your network has to stand out as a true carrier-class infrastructure delivering superior services while achieving business efficiencies.

Characters of Inter-Frequency Handover:-

·       The carrier frequency of the current cell and target cell are different

·       Based on the triggering causes of handover

Inter-frequency handover can be categorized into four types:-

ü  Coverage-based

ü  QoS-based

ü  Load-based

ü  Speed-based

1.The mobility of UE

2.Load Balance

Handover is a basic function of a cellular mobile network. The purpose of handover is to ensure that a UE in CELL_DCH state is served continuously when it moves.

3G Drive Test Case Study:-

Here we are highlighting few cases, which normally occur while doing the DT. It will give the idea to DT engineer regarding to the issues on the site while doing the DT.  There are many other issues which normally occur, and which we have to justify, but all such cases depends upon case by case, for example, Speech Codec issues, SQI issues, UL/OL issues.

If any other issues comes, which are other than those which are discuss below, please kindly let me know so I can provide you the reason to justify them.

WCDMA ( 3G ) Channels "Detailed" Chapter Two/Three

WCDMA ( 3G ) Channels

Channel Mapping

·       The data can be sent through logical layer via different channels in the transport layer.
·       And also one transport channel can be sent via different physical channels.
·       These selection of channels in the transport and physical layer depends on the data itself and radio resource management and its parameters.

Wcdma Channels ( Detailed ) CHAPTER ONE/THREE

WCDMA Channels

Logical Channels are not actually channels but rather they can be defined as different tasks performed by the network and the UE at different times.They describe the type of information to be transferred.
Logical channels are categorized into control channels and traffic channels.Control channels carry the control plane information.Traffic Channels carry the user plane information.
Transport channels describes how the logical channels will be transferred, or it can be defined as how and with what characteristics data is transferred over the interface.
It comes into two groups:
·       Dedicated Channels
·       Common Channels
