Demystifying 5G - An introduction to current research and challenges

Within the past 12 months numerous announcement were made about 5G. But officially, there is no clear definition of 5G yet available. Nonetheless the IMT-Advanced group of the International Telecommunication Union (ITU) has issued a visions and requirements document that set three cornerstones that a 5G technology shall be focusing on: mobile broadband, massive machine type communication and ultra-low latency and resilient communication. All three provide significant challenges by themselves. Mobile broadband is understood to offer significantly higher peak and average data rates per user as today's networks. This can be only achieved by utilizing wider bandwidths, which are only available in the cm-wave and mm-wave frequency spectrum. What frequency bands exactly, that's still undecided and up to regulation. Most promising bands are 28, 39, 40-50, 60 and 70-90 GHz dependent on regional availability. Ultra-low latency requires new PHY/MAC principles, resulting in new waveforms and multiple access schemes to be utilized. Same is true for machine type communication, where one requirement could be the fast access to the network while utilizing asynchronous access methods. All these aspects shall be discussed during this webinar, with an emphasis on how to overcome the mentioned challenges while applying advanced measurement methodologies using test solutions from Rohde & Schwarz.
