In the next few years, fundamental technological transitions are expected both for wireless communications, soon resulting in the 5G era, and for the kind of pervasiveness that will be achieved thanks to the Internet of Things. The implementation of such new communication paradigms is expected to significantly revolutionize people’s lives, industry, commerce, and many daily activities. Healthcare applications are considered to be one of the most impacted industries.

LTE-Advanced networks are spreading widely across the world and they are continuing to evolve as new device features such MIMO 4×4, Carrier Aggregation are being released to move towards the peak data rates introduced by 3GPP Release 12 and 13. Mobile network Operators are looking for technologies that guarantee higher spectral efficiency and wider spectrum usage but they have to deal with limitations due to commercial devices' RF components. This paper analyzes several scenarios, compares them and suggests deployment strategies.

Internet of Things offers a wide spectrum of opportunities for innovative applications designed to improve our life quality. In the energy sector, the developing of smart metering networks allows operators and companies to improve the production efficiency and to offer an enhanced service to customers. 3GPP introduced in Release 13 Narrowband Internet of Things (NB-IoT) as a new cellular technology for providing wide-area coverage for Internet of Things (IoT) and Machine Type Communication (MTC). In this paper, we propose a deployment analysis of a NB-IoT system for smart metering.

The recently standardized Narrow Band Internet of
Things (NB-IOT) is expected to become a disruptive technology
in the IoT market. The low cost, manageability, and reliability
offered by a Mobile Network Operator (MNO) can be the enabler
for the widespread acceptance and deployment of IoT devices.
In this market phase, network planning plays a crucial role in
the possible services forecast, with obvious consequences on the
market analysis by the MNO. Moreover, there are many possible

This paper investigates the benefits of flexible
resource allocation when performing HTTP-based Adaptive
Streaming (HAS) across cellular systems such as Long Term
Evolution (LTE). To guarantee video fluidity in the presence of
fluctuations of the instantaneous video source rate and channel
capacity, we consider a HAS based proxy video manager and
resource controller located at the cellular base station. Based
on the channel quality observed by mobile clients, the manager
allocates the wireless bandwidth to mobile clients for transmitting
