Millimeter wave – An excursion into a new RAT for 5G

As the 5G requirements and timeline move closer towards a global consensus, a new Radio Access Technology (RAT) is emerging not as an alternative but rather as an addition to the 4G-based RAT and its evolution expected in 5G. This new RAT targets a “relatively” new spectrum (above 6 GHz) – also referred to as millimeter wave – where large contiguous bandwidth provides a leverage to deliver on the ultra-high throughput and ultra-low latency requirements. This talk will give an overview of the millimeter wave technology and the challenges ahead towards a successful development of 5G.
