The aim of this paper is to introduce the measurement method for challenging Non-Line of Sight (NLOS) conditions in mobile networks. The need to develop the measurement method appeared LTE (Long Term Evolution) uplink (UL) performance with different antenna technologies when receiving NLOS signal in field tests. Many challenges appeared during the study. This paper introduces the challenges and presents...
The objective of this paper is to compare uplink (UL) performance with different antenna technologies when receiving Non-Line of Sight (NLOS) signal in field tests. The antenna configurations in use were a passive antenna system and an active antenna system (AAS). The radiation pattern can be controlled horizontally by changing its azimuth angle and vertically by changing the tilt angle of the antenna...
In this paper, we describe a spectrum access system (SAS) based Citizens Broadband Radio Service (CBRS) field trial using a live LTE network in the 3.5 GHz band. The latest WInnForum specification guided the implementation of the relevant protocols for SAS operation. Here, we evaluate the performance of a CBRS field trial by using one of the most important performance indicators in a spectrum sharing...
Radio coverage is a crucial component in any radio network design and deployment. In order to develop a design and deployment tool, we studied and utilized two different measurement approaches suitable for estimating indoor WiFi coverage. One of the tested approaches uses a handheld spectrum analyzer, while the other is a protocol-dependent method using standard Windows API calls. The applicability...
Manufacturing systems' digital transformations increase the vulnerability of industrial systems. Cyber security is a continuous cat-and-mouse game. Vulnerabilities are found and fixed, but hackers are usually one step ahead. Cyber security resonates at all levels of society, and the Internet of Things is bringing new threats in this area. Security investments increase while technology development...
Industrial Internet can be viewed as a big opportunity for industry. A large variety of Industrial Internet solutions will change the role of humans in industrial processes. This paper presents our practical experiences using Industrial Internet with a mobile robot. Several sensors embedded in the robot enabled its use for fire detection. The robot was able to analyze data collected from sensors or...
In this paper, a brief review of the computational intelligence and data mining methods utilized in industrial Internet-of-Things experiments is presented. Although the exploitation of data mining and other computational intelligence technologies in Internet-of-Things applications is still in its infancy, some early real-world deployments and testbed cases are noted and investigated, taking into account...
We present an end-to-end ecosystem trial of the Licensed Shared Access (LSA) concept using a live LTE network sharing the 2.3 GHz band with incumbent wireless cameras. The entire LSA concept is implemented introducing LTE network as an additional licensed user in the band with the aid of an LSA Repository for spectrum availability information from wireless cameras and an LSA Controller for managing...
In this paper, the design and development of wireless sensor and actuator networks that enable Internet-of-Things (IoT) solutions are investigated from the perspective of cognitive infocommunications. The reasons, requirements, and issues related to adaptive systems and architectures are presented, and the corresponding intra-cognitive and inter-cognitive communications are examined. The current and...
Cognitive Infocommunications (CogInfoCom) studies the connections between infocommunications and cognitive experiences. This paper presents a practical performance evaluation of an active antenna system (AAS) based on tests performed in a field trial environment with a cellular high-speed packet access (HSPA) network. Cellular networks face the challenges of constantly growing data traffic and demands...
This demonstration presents a live spectrum sharing trial of the new Licensed Shared Access (LSA)/ Authorised Shared Access (ASA) concept. The trial shows the feasibility of the LSA/ASA concept and demonstrates how a mobile network operator (MNO) could take a new shared LSA/ASA band into use in a straight forward manner in response to the growing traffic demand while protecting the rights of the incumbent...
This paper presents the results from a live field trial of the new Licensed Shared Access (LSA) concept using a TD-LTE network in the 2.3 GHz spectrum band in Finland. In the trial a live LTE network shares the spectrum from incumbent programme making and special events (PMSE) service including cordless cameras without causing harmful interference. The trial implements the new LSA concept and the...
This paper presents a demonstration of the new Licensed Shared Access (LSA) concept using a TD-LTE access network in the 2.3 GHz spectrum band in Finland. In the demonstrated trial, the TD-LTE network shares the spectrum of an incumbent spectrum user, who is focused on programme making and special events (PMSE) services. The demonstrator implements the new LSA concept and the required new building...
Enhanced antenna technologies will be key enabling factors in the development of 5th-generation (5G) systems that will achieve significant improvements in system capacity. This paper presents a practical performance evaluation of an active antenna system (AAS) that can lead to high-capacity gain with vertical sectorization (VS). Active antennas have flexible radiation pattern control for adapting...
Cognitive radio system (CRS) technology can help respond to the growing mobile traffic demand by improving network resource usage and gaining access to new shared spectrum bands. This article presents a cognitive radio trial environment (CORE) consisting of cognitive engines (CEs) to control different radio systems [e.g., long-term evolution (LTE) and wireless open-access research platform (WARP)-based...
