“This section will lay out the implementation plan of the entire AAP design, which include configuration
of key networking devices, detailing milestones, activities, resources, and budgets, as well as providing a
deliverables schedule.”
Project Implementation Plan
In this lecture I will discuss implementation plan through an example of an enterprise network.
The figure presents a fictitious enterprise factious network. The company would like to implement a
scalable solution with a routing protocol that provides fast convergence. For optimal routing and packet
forwarding, hierarchical addressing with summarization is required. Users require highspeed access to
the server farm with redundant connectivity for protection. The company has many remote offices; a
redundant connection to the Internet is required to provide the remote offices with nonstop access to its
server farm. For remote offices, a secure connection must be implemented to prevent unauthorized
persons from accessing data.
The first step before creating an implementation plan is to gather existing information about the networks
and all the requirements.
The existing topology provides redundant connectivity among all the network devices. Internet
connectivity is dual homed, which provides redundant access to the remote sites as well as World Wide
Web resources. The equipment can provide all the functionalities that are required, but the software
version of the operation system must be upgraded.
The networking equipment has existing IP addressing that needs to be changed to ensure optimal routing
and forwarding of packets as well as summarization. Requirements for server farm access and remote

office connectivity do not include changes in QoS configuration. The server farm hosts the critical
applications of the company including VoIP, and these require preferred treatment. OSPF is configured
in the network. This configuration must be changed, because a faster convergence time is required.
EIGRP is better choice than OSPF.
Security configuration is required to provide secure access to terminal resources. In this case existing
security is sufficient, therefor no changes are needed.
For this scenario implementation plan would be

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

1. Pre-Planning
Requirement Analysis
RF engineer analyzes the requirement from the customers. The task could be dimensioning and
simulation, current network evaluation or electromagnetic background measurement.
Network Dimensioning
Network dimensioning is the most general activity in pre -planning phase. Network dimension could be
designed by 3 ways. It may come directly from the customer, or from the designing on map. When
there is current network available, the current network analysis or new site survey will possibly be
committed.
Simulation
Simulation with some planning tools is very helpful for the network dimensioning. It provides a way to
check the accuracy of the planning. During the simulation, the propagation model has to be chosen. It
may be chosen by adopting the model of similar terrain that we have, or getting from model tuning
(CW test).
Network Evaluation
Evaluate the whole network performance. For the wireless part, the evaluation is normally made by
drive test and KPI analysis.

2.1. RF Survey
RF Survey Discussion
The customer will pass the job request to the teamleader OR Huawei will propose the site survey plan to
customer. The job requests have to be issued by the customer 2-3 days before the actual site survey date.
The content have to include the site name, coordinate, coordinate projection type and time plan to finish
all the site survey. The team leader have to consider also the method that the customer want the site
survey to be performsince some of the site survey will be done together with the site acquisition that will
slow down the whole site survey progress. In addition, the customer may like to send some engineers to
join the site survey
RF Survey Preparation
The template of RF Survey Preparation Check List can be used to perform the site survey and
customization is performed when required. The engineer has to make sure that the Site Survey Kit is
ready with digital camera, GPS and compass before the site survey is started. The digital map has to be
ready so that the site survey can be performed smoother and easier. The site survey schedule can be
completed with the help of team leader and then obtain the approval from the team leader.
RF Survey
The RF survey is performed in this stage either with engineer from customer or done by Huawei engineer.
For more detailed about the site survey method, please refer to the RF Survey Guideline document. The
information obtained from the site survey is filled into the On-Site RF Survey Report (XXX Site).

The cell naming method, Cell ID, CGI and NCC are obtained from the customer. The customer may provide the cell
naming method or the engineer may propose the cell naming method to the customer and get the approval from the
customer.
Frequency/PN Planning
The team leader is responsible to obtain the information includes the total spectrum available, starting and ending of
theARFCN fromthe customer. Then, the team leader is responsibleto determine the frequency reusepattern and the
frequency hopping method that going to implemented in the project. This may include the total number of channels
dedicated for BCCH and total number of channels for TCH. In addition, the TCH reusepattern such as 1X3 or 1X1
reuse pattern is also determined in this stage. The team leader may call for meeting to discuss this issue internally to
find out the most suitable frequency plan that suit the frequency available and then send the final frequency plan for
customer approval. For CDMAand WCDMAplanning, there is a general guideline for the PN/SN planning.
Coverage/Capacity Highlights
In someprojects that have high coverage requirements, thesite designs have to be determined to ensurethe customer
satisfaction. In this stage, the team leader has to get the proper input either from customer or marketing department.
The consideration may include the implementation of dual CDU solution, type of combiner used, type of high gain
antenna and typeof feeder used.
This consideration is mainly for dual band network. The engineers have to consider how to absorb and control the
dual-band network traffic. The parameters such as the value of CRO, type of HO ( Layer HO or PBGT HO ), HO
thresholds, other vendors parameters studies and proposal to change other vendor parameters have to be considered
so that thetraffic can be distributed more evenly.

ParameterPlanning Consideration
In this stage, the default parameters such as the types of handover that are going to be activated, CRO setting for
traffic sharing, various types of thresholds, for more detailed about the parameters using, please refer to the RNP
Default Parametersetting, (including Dual-band parameter setting) document, have to be determined and then
sent to customer for notification and approval. The default parameters in this stage are not meant to generate the
complete BSC data but more towards letting thecustomer knows thegeneral pictureof the whole network.
All the issues above are combined and a formal report Network Planning Concept has to be delivered to customer
when the design concept is finalized. This planning concept will be used both for Huawei engineer and the customer
to communicate with regional teams if there are. This process also ensures the customer knows well the planning
concept and make thenear future work can be performed smoother.
RNPAcceptance Criteria and Method
In this stage, the KPI definition and KPI target have to be set with the input from customer due to different way of
defining the measurement parameters. Huawei engineer may propose the measurement method if there are no
specified requirements given by the customer. And then outputs the RNO Acceptance Criteria document. But the
KPI targets have to be discussed carefully due to the KPI targets are affecting the future workload. The RNO
Acceptance Criteria document is sent to customer for approval when it is finalized with the co-operation from
Huawei marketing.
Practical Planning
The team leader distributes the planning work to RNP engineer. The engineer does the practical
planning such as Frequency/PN planning, Neighbor planning with the Network Planning Concept.

2.3. Practical Planning
The planning concepts are obtained from the previous stage and will be the conceptual input in this stage.
Frequency/PN and NBR Planning
After the required manpower is obtained, the work is distributed to the engineers to finish the frequency and NBR
planning. Theinputs such as
- Sites coordinate and the azimuths can be obtained from the sitesurvey
- Available spectrum and ARFCN, planning concept, hopping method and digital maps can be obtain based
on the input from thesite survey stage.
After all the designs are done, tools to check on the single way neighbor, co-channel and adjacent channel is used to
verify thework results produced. Thechanges are made accordingly and recorded in thePlanning Evaluation Record.
This document will be theproof for the verification work done and will sent to Headquarter for recording purpose.
Proposal Approval
The approvals, Network Planning Proposal and RNP proposal Approval Report, have to be obtained from the
team leader and the team leader is responsible to send thework to customer for approval. At this stage, the complete
cells parameters and cells properties are configured and filled into the RNP Data Configuration Table. The cells
parameters such as HO type, thresholds, frequencies, neighbors and other parameters are obtained from the
documents that planned internally and approved by the customer. The RNP Cell Data Configuration will be use to
generate thedatabase for all thecells that are going to put on service.
After the data is verified, the data that in the RNP Data Configuration Table is sent to the Data Configuration
Center to generate the BSC data (Database) for the network. And after generating the DBF, the Data Configuration
Center will send it to thelocal RNO engineer and thelocal BSS engineer.

3. Cutover / Launch
Site Installation
In this stage, BSS engineer is responsibility for the quality of the site installation. It will affect the network running
quality. The customer should preparethe conditions of siteinstallation before installed.
Site Commissioning
After the sites installed and running, the BSS engineer must do the commissioning test one by one basing on the
BTS Commissioning Test Checklist (for RNO). During the test, the BSS engineer must pay attention to the
installed quality of BTS hardware, antenna and so on. If there is something wrong in it, it should be corrected and
adjusted fast.
Installation Adjustment
If there is something wrong in installation, it must be adjusted at once.
Hardware Adjustment
If there is something wrong in Hardware, it must be changed or adjusted at once
Antenna Adjustment
If there is something wrong in Antenna installation, it must be adjusted at once.
Cutover / Launch
In this stage, the team leader is responsible for determining the launch plan with the PM and customer. It is
suggested to launch the sites per batch basis. The customer input at this time is important also. The site launch on
batch basis will reduce the number of times for cutover and this can make all other RNP work can be managed

better. At the same time, the team leader has to make sure that the launch schedule is determined by the RF team
leader but not PM only. ALL (RF Team Leader, PM and Customer) parties have to discuss and determine the
launch plan. After this, the cells that launch in this batch are unbarred and the sites are considered on service. Also,
it’s very important for the BSS engineer to do the test one by one basing on the BTS Commissioning Test
Checklist (for RNO) to prove that the site running status is good. At the other side, the traffic statistic is checked
per hour basis for about 2 to 3 hours to verify the successful of the launch process. After that, a short discussion
will be called with customer to conclude whether the launch is success or not.
Monitoring
The on-site BSS/RNP engineer will take the monitor after the successful Cut-over Launch. For example, the daily
traffic statistic report is sent to the customer to show the overall network performance and quality and the drive test
to verify the coverage areas will base on the customer requirements. If there is something wrong in the network,
the Daily Performance Monitoring report will be sent to theteam leader and the customer.

4. Network Optimization
Cutover/Launch (BSC Cutoveror Site Launch)
During implementation period, Huawei will begin optimization only when a certain number of continuous sites are
put on service (for example, 90% of the continuous sites are put on service). For the specified optimization project
where there is no site launch at all, thefirst step is to collect and check sitedatabase (engineering parameter table).
DT Optimization /KPI Optimization
DT optimization and KPI optimization are committed at the same time. According to the plan of project, self-check
should be involved to make clear whether the network quality achieve acceptance criterion after X weeks’
optimization. If acceptance criterion has been achieved and the acceptance time has not arrived, the project moves
to Network Monitoring process. Otherwise, analyze the failure reason. If it is because of network optimization,
enhance the optimization devotion. If it is because of other reasons, transfer the problem to local or remote
Technical Support until the criteria are met, or just present the explanation. In the end, the RPO project moves
into network acceptance process.
Network Monitoring /Technical Support
If acceptance can not be done according to the plan because of the reasons other than network optimization, it is
necessary to co-ordinate project team, local office and company support team to stress on tracking and settling the
network problem. So the support what we said here includes optimization team, R&D team and marketing team,
not only optimization technical support team.
Network Acceptance
According to network acceptance criterion and method, confirm the optimization result with customers.

3.1 DT optimization
DT Preparation
Before DT optimization, the engineer is required to work out the drive test plan such as test purpose, which route to
go, test method, duration to finish theplan, test car, test equipment and etc. DT Preparation Checklist is helpful to
do self-check.
Drive Test
Either the engineer or the sub-contractor performs the drive test. The obtained result will be analysis by the engineer
and 2 reports (Drive Test Analysis Report and Drive Test Report) are generated and sent to team leader for
approval. The appropriate reasons have to given if the continuous 10 samples collected have low signal or bad
quality. The team leader then passes the report to the customer for approval and in the same time show the new
launch network performance to the customer. Please refer to the Optimization and FAT Test Standard for more
information about the Drive Test method. The drive test analysis can be done based on the urgency of the network
situation. If a lot of problems found during drive test, the data have to be sent back ASAP and then correct the
problems accordingly.
DT Data Analysis
When analyzing the drive test data, we have to record the time, position, phenomenon where there is network
problem, specify the reasons and propose possible solutions. DT Data analysis table is applied to every time of
drive test. After DT analysis, estimate whether the result can meet the target requirement. If the result meets the
target, confirm the work with team leader.
Result confirmation
Finish the DT optimization according to DT Data analysis table and DT optimization Bi-weekly report.

Antenna / Parameter / Configuration adjustment
After drive test, such solutions as antenna adjustment, parameter adjustment or configuration adjustment may be
applied. In order to compare the performance before and after adjustment, engineering parameter table and
engineering parametertable are used.
After all the adjustment, drive test again, resume the circular process of DT optimization until satisfying the drive
test target.

3.2 KPI optimization
Traffic StatisticData
In optimization phase, obtain the traffic statistics from OMC every day. Normally the statistics is of previous day.
Network Monitoring
According to the statistics data, find out the abnormal site or cell, for example, no traffic, no handoff, call drop,
etc. The abnormal cell is normally caused by the hardware failure. All these cells are analyzed by the BSC/RNP
engineer and they will start the work to correct it then. The RF engineer also can initiate the BSC engineer to solve
the hardware related issues when some problems about the hardware are found in thesystem.
Problem analysis /Terms of Solution /Discussion /Solution Implement
During optimization, worst cells are listed out based on theKPI items, and they may benamed as problem cell here.
Theproblem cells are analyzed and theproper changes are proposed to the customer. Theproposal may include how
to solve current network problems such as add/relocate TRX, parameters changes and etc. The main purpose is to
improve the total performance of the network. All the more complex solution can also be documented and sent to
RNP support department. At the same time, the product suggestion can also be given to improve network capability
and the efficiency of thework.
After the problem cells proposal and the change request are ready, the discussion with customer is held and the
parameters changes are done after the meeting. It is suggested that the meeting should be held earlier so that the
parameters changes can be perform in the same date after the meeting with the customer. The second suggestion is
try to keep the records of the parameters changes so that the same parameters values won’t be performed again and
again.

3.3 Network monitoring
Customercomplaint / Traffic statisticdata
During network monitoring phase, maintenance engineer is keen on customer complaints and traffic statistics.
Daily monitoring
According to the customer complaints and statistics data, find out the abnormal site or cell, for example, no
traffic, no handoff, call drop, etc. The abnormal cell is normally caused by the hardware failure. All these cells are
analyzed by theBSC/RNP engineer and they will start the work to correct it then.
Problem solving / Report
If there is some problem found during monitoring, on-site engineer solves the network problem. During this phase,
it is possibleto ask for assistance from local office or headquarter.

3.4 Technical support
Problem identification & description
When the on-site engineer ask for technical support from specific regions or headquarter, he may fill the Problem
Feedback Form and send to regional / headquarter technical supporter or upload the problem through Huawei
CRMS(Customer Request Management System), and the technical supporter willresponsethoserequests.
Regional technical support
There are several regional technical support platforms in AP, CIS, MENA, SA, etc. When the technical support
experts there get the support request, they will deal with problem directly or through CRMS system, and try to
solve the problem with on-site engineer finally.
Technical support of HQ
If some problems can’t be solved at regional technical support platform, they will flow to headquarter technical
support center. Then the technical support experts there will continue to deal with them. Headquarter technical
support teamincludes experts from R&D, BSS and RNP.
Solution implement /Result confirming
With the assistance from regional or headquarter technical support team, the on-site engineer discuss the solution
with customers and then implement it. If the problem has been solved, notify H&Q technical support to close the
problem. For typical problem or important problem, problem investigation report should be generated to
customers.

4. Network Acceptance Process
In theprocess of Planning Concept, the KPI have been defined and agreed with the customer. The formal document
RNP Acceptance Criteria and Method has to be produced and signed both by the marketing department and the
project manager. This document normally is done after the contract is secured.
After the optimization for some time and all the KPI values have passed the target value as defined in the KPI
document, the FAT can be initiated and Network Optimization Report is prepared and sent to the customer to end
the project. The FAT criteria have to be considered in the report that may include the drive test result and the
breakdown of the KPI targets. Then the report is sent to the team leader for approval and then for customer approval.
Complete optimization
After getting the approval of the optimization, all optimization items finish. Backup the BSC data in the network,
and pigeonhole all project documents to company server according to RNP Document Guideline.
