Setting up LTE HetNets using ns-3
As we discussed in the previous topic, even in open spaces, eNBs are not able to cover a complete area. Hence, it is necessary for operators to deploy small cells to improve the coverage area and serve their users with improved signal strengths. In this section, we will discuss how to set up LTE HetNets to meet indoor UE or home UE requirements (which are deployed inside building rooms), as well as outdoor UE requirements (outside building blocks). To set up LTE HetNets, we will complete the following tasks in our hands-on activity:
- Setting up building placement models
- Deploying home eNBs, such as femtocells, inside the building rooms
- Configuring home eNBs with Closed Subscriber Group (CSG) IDs to restrict their access to indoor UE
- Deploying macro eNBs (outdoor eNBs) to serve outdoor UE
- Providing all UE with internet access
- Testing the ns-3 CSG implementation details, such as restricting home eNBs’ access
- Testing...
