Low Power Wide Area Networks (LPWAN) are able to combine long range communication with a low energy consumption sacrificing performance in terms of bit rate and message frequency. This thesis presents a general evaluation of the LPWAN characteristics and a description of the LPWAN protocols LoRaWAN, SigFox and NB-IoT. It also covers a method to evaluate if a LPWAN technology would be a suitable choice of communication technology for a certain use case. Lastly, it covers the implementation of LoRaWAN on a connected electromechanical lock and investigates in the real life performance of the lock

The United States Federal Communications Commission (FCC) in its recent report and order has prescribed the creation of Citizens Broadband Radio Service (CRBS) in the 3.5 GHz band to enable sharing between wireless broadband devices and incumbent radar systems. This sharing will be enabled by use of geolocation database with supporting infrastructure termed as Spectrum Access System (SAS). Although using SAS for spectrum sharing has many pragmatic advantages, it also raises potentially serious operational security (OPSEC) issues. In this thesis, we explore OPSEC, location privacy in particula

In the Internet of things (IoT), many applications will require low-power and low-cost to achieve long lifetime and scale (respectively). These types of applications are referred to as massive IoT, as opposed to critical IoT, which emphasizes ultra-high reliability and availability and low latency. One type of network catering to massive IoT applications are Low-Power Wide Area Networks (LPWANs), and presently, many LPWAN standards are trying to assert their role in the IoT ecosystem.

The Internet of Things (IoT) is a fundamental pillar in the digital transformation since it enables the interaction with the physical world by means of sensing and actuation. 3GPP recognized the importance of IoT by introducing new features aimed at supporting this technology. In details, in Rel.13, the 3GPP has launched the NB-IoT to provide support for LPWAN. Since these devices will be distributed also in such area where the terrestrial networks are not feasible or commercially viable, satellite networks will have a complementary role thanks to their capability to provide worldwide connecti

For energy saving, small things (sensors) usually stay in the idle mode and only wake up when they have traffic demands. In traditional LTE, the MME invokes UEs by notifying them via a paging message including a list of their IDs. However, such one-by-one notification will incur an unacceptable signaling overhead in an IoT network when the ID list is long. To address this issue, this work presents “page by hint” (p-Hint), an ID-free paging mechanism that allows the MME
