Millimeter-Wave
Mm-Wave have been used in past for other purposes, this is the first time that such frequencies will be used for mobile terrestrial networks, in particular they are used related to mobility, customer expectations in terms of device battery life, reliability and predictability of operation in terrestrial environments, etc.
Internet of Things
Internet of Things
Nowadays Internet-of-Things (IoT) represents a reality diffused across different areas : industry, medical instruments, science. It is the ability to connect numerous devices with a single user interface to the local network. In this scenario the spectrum becomes more crowded, the devices have to operated in a limited bandwidth, with good linearity to enhance tolerance to in-band and out-of-band interferers. The other key factor of IoT devices is the Power consumption, in particolar for mobile devices. Advanced techniques are experimented to dramatically reduce the power dissipation and enhance energy efficiency of wirelessly connected devices.
