d Implementation Phase Figure 1-1. Radio network planning phases Dimensioning Phase The dimensioning phase will mainly involve information and requirement gathering from the customer from which the initial objectives for the radio network planning can be set. Some of the key inputs that are considered or required to be performed in the dimensioning are outlined in the sections that follow. Configuration for the Site As part of the configuration details, it is important to understand whether the site will be configured for a multiple- input and multiple-output (MIMO) or single-input and single-output (SISO) system. If the system is MIMO, then the transmission mode needs configuration. Also, as a part of site configuration, it is important to understand how many cells will be installed or eNodeB (i.e., sector configuration) for each site. User and Traffic Volume Estimation As a part of dimensioning, it is important to estimate the user volume and the traffic volume for each site; for example, the number of users in an urban site will be very high compared with the volume for a rural site. Similarly, the traffic volume will be higher in an area that has small offices set up in comparison with a highway deployment. The user and traffic volume estimation directly impacts the cell size that can be supported for a particular area and the capacity requirement. It also is useful for parameter settings like physical random access channel (PRACH) configuration settings, scheduler settings, and so forth. Apart from the traffic volume, it is also important to understand the traffic type that will dominate the cell SO the dimensioning can be done accordingly by calculating the net bit rate for the traffic type, 4G voice over Internet protocol traffic (VOIP), streaming traffic, hypertext transfer protocol (HTTP) traffic, and so forth. CHAPTER 1 NETWORK PLANNING Coverage and Capacity Estimation The customer should be able to provide the information on the area that is planned for service and also the quality of service offered f
