Millimeter Wave Cellular Systems – the Future of 5G MmWave is a promising technology for future cellular systems. Since limited spectrum is available for commercial cellular systems, most research has focused on increasing spectral efficiency by using OFDM, MIMO, efficient channel coding, and interference coordination. Network densification has also been studied to increase area spectral efficiency, including the use of heterogeneous infrastructure (maco-, pico-, femtocells, relays, distributed antennas) but increased … Continue reading →

Multi-Hop Networking Multi-hop, or ad hoc, wireless networks use two or more wireless hops to convey information from a source to a destination. There are two distinct applications of multi-hop communication, with common features, but different applications. Mobile ad hoc networks (MANETS) A mobile ad hoc network consists of a group of mobile nodes that communicate without requiring a fixed wireless infrastructure. In contrast to conventional cellular systems, there is … Continue reading →
