规划站点的勘察就是依据网络拓扑结构设计最终输出的站点信息，通过现场查勘

The survey of the planning site is the process of designing the final output of the site information according to the network topology, landing the planning site through the site survey and design, and adjusting the various planning parameters according to the site environment. <br>Planning sites are sites that have not been verified by actual surveys and meet the requirements of the topology in theory. During the site survey, it is necessary to select candidate sites that are highly consistent with the planning according to the site environment within the allowable deviation range, and then conduct survey and design; for existing available stations, you can directly collect relevant parameter information through site survey and design , Simultaneous survey and design. During the survey of newly added planning points, each planning station normally needs to select 2-3 alternative stations on site. <br>After completing the survey and design, it is necessary to design and review the site surveyed on site. If in the actual survey process, it is found that all the candidate points of a planning station do not meet the requirements, it is necessary to re-site and survey the planning point; if the area where the planning point is located has not been able to select a suitable candidate site, then The network topology of the area needs to be adjusted within the scope. <br>After completing the survey of the planned site and passing the audit, the design plan of the site needs to be output. <br>The design output of the site mainly includes two parts of information, one is to output the drawings consistent with the plan made by the site survey, which is used to guide the construction; the other is to output the relevant wireless parameters. <br>In the mobile network architecture, the indicators related to the wireless air interface have a great impact on the performance of the wireless network. Therefore, the rational design and optimization of relevant wireless index parameters is also one of the important steps in network planning. According to the service objects in the network, the wireless index parameters in the mobile network architecture can be divided into two categories: engineering parameters and resource parameters. Engineering parameters refer to index parameters related to design, installation and commissioning that are closely related to the project, such as antenna gain, feeder loss, antenna platform height, direction angle, downtilt angle, system frequency point, equipment transmission power, etc. These parameters are generally It is determined during the network planning stage and generally does not change after the site is opened. The resource parameter refers to the index parameter related to the wireless resource configuration and application. Usually, it is transmitted on the wireless interface to ensure the synchronization between the base station and the mobile station. It is generally designed and output by the network optimization and equipment manufacturers. , And monitoring through the network management system.

The survey of the planning site is the process of designing the final output of the site information according to the network topology, landing the planning site through the site survey design, and adjusting the planning parameters within the scope according to the site environment.<br>A planning site is a site that has not been verified by a physical survey and theoretically meets the topology requirements. When site survey is carried out, it is necessary to select a candidate site with a high degree of planning according to the site environment according to the permitted deviation, and then carry out the survey and design, and for the existing available stations, the relevant parameter information can be collected directly through the site survey design, and the survey and design are carried out at the same time. During the survey of the new planning points, the normal planning station requires 2-3 alternative sites to be selected on site.<br>After the completion of the survey design, the site of the site survey needs to be designed and designed. If, in the actual survey process, all the alternatives of a planning station are found to not meet the requirements, the planning point needs to be re-positioned and surveyed, and if the planning point is located in the area has not been able to select a suitable candidate site, the network topology of the area needs to be adjusted within the scope.<br>After the site is completed and approved, the site needs to be designed to be output.<br>The design output of the site mainly includes two parts of information, one is the output and the site survey of the plan of the consistent drawings, used to guide the construction, and the other is the output of the relevant wireless parameters.<br>In the mobile network architecture, wireless empty-related indicators have a great impact on the performance of wireless networks, so the rational design and optimization of the relevant wireless indicator parameters is also one of the important steps in network planning. According to the service object in the network, the wireless indicator parameters in the mobile network architecture can be divided into engineering parameters and resource parameters. Engineering parameters refer to the design, installation and opening related to the project related to the indicator parameters, such as antenna gain, feeder loss, antenna platform hanging height, direction angle, lower inclination, system frequency point, equipment transmission power, these parameters are generally determined in the network planning stage, after the site opened generally does not change. Resource parameters refer to the wireless resource allocation and application-related indicator parameters, usually in the wireless interface transmission way to ensure the synchronization between the base station and mobile station, generally by the network excellent and equipment manufacturers design and output, and through the network management system monitoring.

The survey of the planning site is the process of landing the planning site according to the final output of the network topology design, and adjusting the planning parameters according to the site environment.<br>The planned site is a site that has not been verified by actual investigation and meets the topological structure requirements in theory. During the field survey, the candidate sites that are highly consistent with the planning shall be selected according to the site environment within the allowable deviation range, and then the survey and design shall be carried out; for the existing available stations, the relevant parameter information can be collected directly through the field survey and design, and the survey and design shall be carried out at the same time. During the survey of new planning points, normally each planning station needs to select 2-3 alternative stations on site.<br>After the completion of survey and design, it is necessary to conduct design and design joint review on the site survey site. If in the actual survey process, it is found that all the alternative points of a planning station do not meet the requirements, the planning point needs to be relocated and surveyed; if the area where the planning point is located has not been able to select the appropriate candidate sites, the network topology of the area needs to be adjusted within the scope.<br>After completing the survey of the planned site and passing the review, it is necessary to output the design scheme of the site.<br>The design output of the station mainly includes two parts of information, one is to output the drawings consistent with the scheme made by the site survey, which are used to guide the construction; the other is to output the relevant wireless parameters.<br>In the mobile network architecture, the performance of wireless network is greatly affected by the related indicators of wireless air port, so the reasonable design and optimization of the related wireless indicators is also one of the important steps of network planning. According to the difference of service objects in the network, the wireless index parameters in the mobile network architecture can be divided into engineering parameters and resource parameters. Engineering parameters refer to the design, installation and opening related index parameters closely related to the project, such as antenna gain, feeder loss, antenna platform hanging height, direction angle, dip angle, system frequency point, equipment transmission power, etc., which are generally determined in the network planning stage and generally remain unchanged after the station is opened. Resource parameter refers to the index parameter related to wireless resource configuration and application. Usually, the synchronization between base station and mobile station will be ensured by transmitting on wireless interface. Generally, it is designed and output by network optimization and equipment manufacturer, and monitored by network management system.<br>
