Wireless Network Planning Conclusion

Conclusion

To date, mobile communications technology has developed to the extent that theborder of the many related technologies have blurred: the cross infiltration of basestation and base station controller, (wireless) network planning, network optimization,and the combination of wireless side products, etc. The purpose is to improve thewireless products market adaptability, the wireless network quality, and expansion ofthe wireless network services. So network planning today is not the one it used to bereferred to before. Its not confined to a department, but in the context of a technologyand service, and one that denotes broader range. It involves participation andsystem-formation from all the wireless products departments. It also includespersonnel-training mechanism as well as shift mechanism.

The characteristics of wireless system lie in the mobility of the subscribers and thecellular networking as well. The mobility dictates that the designers have profound

understanding on the complexity and connectivity of the macro wireless cellularnetworking, that they perceive the demands from the switch office side and analyzethe potential uncertainty of the wireless network. One obvious feature is that manywireless personnel in big companies must receive the training on the theory ofwireless propagation and practical activities on network drive test and backgroundanalysis before they are to be engaged in any concrete research or projectengineering. The purpose of doing so is to strengthen their understanding on thecharacteristics of mobility and cellular networking.

In the following sections we will discuss the duties and responsibilities of networkplanning from four perspectives: research on network planning technology, briefdesign and participation involved in wireless products, wireless products marketingstrategy, and turnkey wireless products marketing plan preparation.

1 Research on the Network Planning Technology

Research on the network planning technology includes: planning methods andsoftware implementation, optimization methods and software implementation, thefocus of which in on research, simulation, and experimentation of planningoptimization methods. As for the software implementation, secondary development ofcooperation-aided core algorithm module can be used to save the cost and enhancethe competitiveness. In addition, another important aspect is the good interfacebetween the planning optimization software and OMC database, as well as goodmanagement on the project. Thus most of the practical project planning optimizationcan be done by using the platform that is based on the software to free the front-lineproject engineers from the repetitive handiwork to make them focus on how to

improve the network quality.Broadly speaking, the ultimate purpose of network planning optimization is toestablish a wireless network that has good coverage, good quality, good capacity, andgood dynamic adaptability to meet users demands on voice and data service. For thereason hereof, research on planning optimization is the research on networking that ismarket-oriented and market-driven. The result of the research can be on the onehand a planning optimization method for the general mobile system, on the otherhand, can accelerate the development and perfection of the product to meet thenetworking demands, or can even present new algorithm, standards, or protocols.

The research topics that can be derived now include: The propagation characteristicsof some mobile communications frequency bands, layered net structure (including thestructure inside the system and between the system), new technologies (air interface

coding, voice speed, transceiver diversity technology, multiple access, multiple users

detection, spread spectrum technology, multiple carrier propagation, soft handover,fast power control, intelligent antenna, new radio frequency devices, etc.), evaluationon the effect of, and contribution from wireless network performance, frequencyutilization ratio and the evolution trend of capacity, traffic module, and data throughputmodule and their effect on the network performance, algorithm module in the planning

optimization tools.

2 Participation in the Primary Design of Wireless Products

The purpose of networking research is to serve the product development to improvetheir market competitiveness. Both the result and the procedure of networkingresearch have significant guide in the product development.

The result of the networking research can directly be the algorithm of some basestation controllers (channel management, power control, handover management, andtraffic analysis, etc.); It can give advices and assessment on the projectestablishment, new function development, and new version concerning the basestation controller, base station, and OMC products from the perspective of

networking. A project team can be set up to co-solve the problems from online thathave common features.

Before the primary design of the products, it is very necessary to take the manycomplex networking requirements into account. Though the implementation ofdetailed functions can be carried out step by step, the overall frame must be far-sighted and scalable. This can prevent the later non-marketability of the product andinability to improve the network quality.

3 Wireless Products Marketing and Marketing Plan Preparation

The marketing concerned here is the network marketing, what is sold is solutionstrategy, including providing solution strategy according to the switch offices

requirements or even providing solution strategy for market creation for the switchoffice. The essence of it is to provide a competitive networking philosophy to meetcarrier and users demands in light of technology, cost, and user group. It is especiallycompetitive and practical if the decision-makers join the practical networking analysiswhen deciding the whereabouts of the product according to the market analysis.

On the other hand, when preparing a concrete marketing plan, especially whenconcerned with new carrier or new frequency band network, former network beingblank, the manufacturer needs to present whole set of networking plan. The planningpersonnel need to construct the future network structure taking into account thewireless side equipment and mature networking. This demands not only the futurenetwork quality and scalability, but also consideration of the wireless cost to enhancethe tender competitiveness. For the sake of reaching the best balance between thenetwork indexes and quotation (investment), the number of base stations, the baseconfigurations, antenna-feeder selection, frequency spectrum requirement, andnetworking are strictly related to the equipment and mature planning methods as well.This is especially important when concerned with the key project expansion.

For overseas TURNKEY project, tender cost is especially eye-catching. Wirelessnetworking directly demands a series of investment such as equipment house, tower,power supply, and propagation. The planning personnel need to decide theappropriate networking in light of the equipment performance, and mature planningmethods and to reduce the wireless cost at the prerequisite of ensuring the laternetwork indexes. A simple example is, the higher the frequency utilization ratio, thegreater the base station configuration, and the fewer the number of base stations,thus reducing the total cost significantly.

4 Wireless Project Implementation

Project implementation is that part of the cycle that finally turns over the network tothe users. At this phase, the planning personnel, as well as the project manager,

perform thorough coordination and communication in light of project progress,turnover method, and quality control.

In the field where the project is being implemented, the planning personnel, as thepersons in charge of the network quality, must assist in setting up the pre-warningmechanism for the network quality, report to the leader of the switch office, and takepart in the training, and planning optimization.

Meantime, the planning personnel must prepare the next-phase expansion newconstruction plan according to the implementation progress and actively guide theswitch office.

It is very important for the project manager to familiarize himself with the planningoptimization service. It helps the project manager to consider the projectimplementation in all directions of networking, and to allocate the resources

effectively according to the urgency in case urgent situations arise.The characteristics of wireless products fully explain the importance of networkingresearch for market survival. But it takes a lot of efforts to train successfully aprofessional networking researcher or a team with such spirit in mind. Departmentbarriers must be broken, abundant opportunities must be available, and managerialconvenience must be given to such personnel for them to participate in the whole flowand get experienced in all parts of the cycle. This is the steps that we take to nurtureour personnel in the field of wireless network: practical installation and test of wireless

equipmentoptimization/planning of the networkparticipation in technical supportand IPD requirement management and analysis, exercise, experience summarization,

theoretical improvementoutput to the departments or become a professionalnetwork researcher. Personnel of other wireless-related departments can also takepart in some of the practices to improve their understanding on networking.
