Ultra-Dense Networks: Taxonomy and Key Performance Indicators

One major influence on the future deployment of cellular networks will be a continuous increase in traffic inside mobile broadband systems. Moreover, traditional macrocell-based communication struggle to keep up with enormous expansion demand for communications services future. Densification is required if we are meet comprehensive needs end terminals wide range applications. leading concepts this competitive environment Ultra-Dense Network (UDN) where access nodes and/or links per unit area densified, aim improving overall network performance. The location UDN meets criteria symmetry high probability. Ultra-dense cell aims reduce physical distance between transmitter and receiver order boost system performance generally optimize values variety key indicators (KPIs). This paper provide taxonomy UDNs specifically UDN-related KPIs. Initially, address complex questions “What current understanding what ultra-dense they should be, how can measure their performance?” by shedding light fundamental characteristics UDNs.
