What have we learnt about coverage in the mmWave bands? How will interaction between high (mmWave) and low (sub-6GHz) frequencies operate and what roles will each play? Considering algorithms are necessary to ensure session continuity, where high speed services can be delivered effectively and network quality is assured. Considering indoor mmWave opportunities, mmWave coverage prediction and planning tools, 5G Deployability and Deployment aspects of mmWave Access Points and FD-MIMO/Massive MIMO antennas in sub 6 GHz. This workshop will attempt to cut through the hype and address the fundamental issues the industry faces as we approach the first release of the 5G standards.

Workshop Goals

  • Assessing which new and emerging unique use cases will evolve?
  • Exploring device challenges and roadmaps, co-existence challenges between 5G and 4G-LTE
