ZTE CDMA network planning & optimization philosophy
Network planning determines network optimization
Network planning is the key factor to network construction;
Network optimization is to improve network quality during the network construction;
Scientific planning will get twice the results with half efforts;
Network optimization is the important input of later planning design
The communication between network optimization and network planning influence the network design quality
The network optimization data is the source of network planning design
The network optimization engineer must participate in the network design
Shorten the time and manpower by Network simulation
Testing point by point to design the network will waste the investments of operator
Credible network simulation guide the network planning and optimization
Antenna repetitious adjustment only cause complaint

Work out solution
Wireless network optimization: Performance data tells everything
Be favor of bald data and skillful at analyzing data
Find the relationship with data by Statistical tools
Network optimization originated from data and ended in optimization result’s data assessment
Wireless network optimization: Focusing on performance index
Objective performance indexes determine the customer Satisfaction
Performance Index can be quantitatively analyzed
The ideas show that optimization should base on data
Network maintenance optimization: The balance between network performances
The performance balance of complex network is achieved by maintenance optimization
When you “get” something you must have “lost” some others in another way
The balance between quality and capacity
Engineering Quality impact the network performance greatly
Fast work doesn’t mean good work;
The network optimization engineer should never continue the unfinished work for engineering supervisor;
One poor quality site worsen the whole network;
Keep consistency by documentation
Experience share by expressing it in words
No documents, high risks
Private equals wholly drop behind
Read documents is a kind of self-training
Yesterday no more
Urban high sites do not meet the dense network requirements
Have your “neighbor” changed? Adjust the neighbor list in time
Equipment hardware aging, antenna, feeder cable and connector affect the network quality
Is the network parameter still feasible?
Establish network planning optimization expert team
Our Suggestion
Elaborate network requirements of operators
Golden service requirements of operators
Enterprise kernel competitive capability requirements of operators
Our Suggestion
Emphasize on the practicability of network planning
Network design determine network quality, network
optimization is continuous improvement
Network design determine the network optimization
workload, network optimization result influences the
network design
Credible planning simulation ought to be regular co
ntents during network planning
Our Suggestion
Combination among the strong ones, improve network planning and optimization level
Network optimization efficiency and the optimization
engineer Technological accomplishment are
inseparable;
Network optimization service supplier with operator or
manufacturer background is the best cooperator for
CDMA network optimization;
ZTE CDMA network planning and optimization group is
the industry outstanding network planning and
optimization service supplier;
