Heterogeneous networks use a mix of different cellular technologies and base station types to improve network capacity and coverage, especially in crowded areas. This includes macro base stations covering large areas, indoor pico base stations handling 70% of traffic, and micro and small cells to further improve coverage. By 2020, there will be over 50 billion connected devices relying on networks employing heterogeneous strategies to optimize the mobile experience.
