The proper planning of the HSPA+ is a very important activity that will determine to a large extent the coverage, capacity, and quality of the service. No matter how much effort is invested in maintaining a network, if the original planning is flawed it will be a constant headache for the engineering teams.
The main focus area when deploying HSPA+ are the radio nodes, including NodeB site location and antenna and power configuration. This chapter provides practical guidelines to take into account when performing the RF planning, however it does not include the amount of detail that can be found in specialized RF planning books such as . Although the main emphasis is put on the Radio Access Network (RAN) nodes, basic considerations around core and backhaul design are also discussed.
In addition to deployment aspects, the chapter also provides useful information to help manage capacity growth, including multilayer management and network dimensioning guidelines.
The performance at the radio layer has a direct impact on the experienced data rates on the application layer and, ultimately, on the experienced user data rate at the application layer. The stronger and cleaner the signal, the higher the data rate that can be achieved; and vice versa, in challenging radio conditions the throughput will be reduced since the physical layer adapts the Modulation ...
