HetNets/Small cells: reliable small cell planning (part 2 of 4)

small cell planning

Reliable planning of small cells is essential for important and critical deployments. Consider hospitals, manufacturing facilities or VIP (CxO) office floors and meeting rooms (the list of examples is endless). Successful and cost-effective planning, and with it small cell deployments, require planning tools that ensure highest reliability and accuracy. This, however, is not always the case as floor plans might…

Smart macro network enhancements: antenna tilt optimization

antenna tilt optimization

Antenna tilt optimization is a cost-efficient and smart approach to increase the capacity in mobile networks. Today, operators have to focus more and more on data capacity and network densification. Also, particularly in urban and dense urban environments, macro cells need to be smaller and coverage needs to be limited. One important method to achieve this is antenna downtilting. It…
