HetNet/Small Cell Planning & 5G Network Architecture

Course Overview:

Outdoor small cells put cost-effective capacity and coverage right where they are needed most. If you are deploying thousands of cells, how can you rapidly choose the best location for each small cell? The challenge: You’re aiming for better performance and also need to get the cells up and running fast.

Tools designed for placing a few macro cells won’t help you do this job effectively. That’s because the number of outdoor small cells you need is much larger, and the placement issues are more complex. To cover the geography of a city center, for example, a small cell layer would typically need up to 10 times more cell sites than would be used in a macro network.

Effective network planning is essential to cope with the increasing number of mobile broadband data subscribers and bandwidth-intensive services competing for limited radio resources. Operators have met this challenge by increasing capacity with new radio spectrum, adding multi-antenna techniques and implementing more efficient modulation and coding schemes.

One way to expand an existing macro-network, while maintaining it as a homogeneous network, is to “densify” it by adding more sectors per eNB or deploying more macro-eNBs. However, reducing the site-to-site distance in the macro-network can only be pursued to a certain extent because finding new macro-sites becomes increasingly difficult and can be expensive, especially in city centres. An alternative is to introduce small cells through the addition of low-power base stations (eNBs, HeNBs or Relay Nodes (RNs)) or Remote Radio Heads (RRH) to existing macro-eNBs. Site acquisition is easier and low cost with this approach and also correspondingly smaller.

This training address the most promising approaches to RAN architecture, functions, interfaces and protocols redesign towards IMT2020 (5G). Design constraints, reliability, dependability and extremely low latency will be covered. The possibility of supporting different types of software-defined air interfaces, frequency bands and multi-tenancy models are also a part of the challenges that need to be addressed.
