Trials of 60 GHz radio for a future 5G New Radio (NR) solution for high capacity CCTV offload and multimedia transfer

This paper studies the radio interface performance of a 60 GHz radio in both indoor and outdoor conditions. The target is to assess its suitability for resolving emerging needs in the public transport, especially, in rail traffic, to transfer large amounts of data from vehicles to the stations and vice versa, during a short period of time. 60 GHz could also be ideal band for the wireless inter-carriage connection between the railcars. The related services and requirements are defined in the 5G specification Mobile Communication System for Railways - TS22.289. 60 GHz band is also included in the 5G standard as an unlicensed band

Rapidly deployable network system for critical communications in remote locations

This paper presents a transportable and rapidly deployable network system, which can be used to provide local voice, video and data connectivity for critical communications in remote locations and Internet connectivity through commercial mobile network, if available. The network is a stand-alone system, which is independent of external electricity and Internet. It is built with commercial off-the-shelf equipment and software. This paper presents trials of a local tactical voice service, a TETRA-compatible push to talk application, and Licensed Shared Access evolution spectrum manager along with radio signal measurements on 700 MHz and 2300 MHz frequency bands

Spectrum occupancy measurements in the 2.3-2.4 GHz band:Guidelines for licensed shared access in Finland

This paper presents results from spectrum occupancy measurements in the 2.3-2.4 GHz band at Turku, Finland. The band is currently under study in European regulation and standardization for mobile communication systems. We review the recently introduced Licensed Shared Access (LSA) concept as a potential means for making the 2.3-2.4 GHz band available for mobile communications on a shared basis while protecting the rights of the incumbent spectrum users. The spectrum occupancy measurements conducted in one location in Finland show that the use of this band is rather low indicating that there might be potential for mobile communication systems to share this band with the incumbents under the LSA approach. Based on the obtained knowledge about the use of the studied band in Finland we create a set of guidelines for LSA to make the operation efficient both from the technical and economic viewpoint

The geolocation database informs the device of which channels can be used at a given location, and in the UK/EU case, which transmission powers (EIRPs) can be used on each channel based on the technical characteristics of the device, given an assumed interference limit and protection margin at the edge of the primary service coverage area(s). The UK regulator, Ofcom, has initiated a large-scale Pilot of TV White Spaces technology and devices. The ICT-ACROPOLIS Network of Excellence, teaming up with the ICT-SOLDER project and others, is running an extensive series of trials under this effort. The purpose of these trials is to test a number of aspects of white space technology, including the white space device and geolocation database interactions, the validity of the channel availability/powers calculations by the database and associated interference effects on primary services, and the performances of the white spaces devices, among others. An additional key purpose is to undertake a number of research investigations such as into aggregation of TV White Space resources with conventional (licensed/unlicensed) resources, secondary coexistence issues and means to mitigate such issues, and primary coexistence issues under challenging deployment geometries, among others. This paper describes our trials, their intentions and characteristics, objectives, and some early observations

The UK regulator Ofcom has initiated a pilot of TVWS technology in the UK. This paper concerns a large-scale series of trials under that pilot. The purposes are to test aspects of white space technology, including the white space device and geolocation database interactions, the validity of the channel availability/powers calculations by the database and associated interference effects on primary services, and the performances of the white space devices, among others. An additional key purpose is to perform research investigations such as on aggregation of TVWS resources with conventional resources and also aggregation solely within TVWS, secondary coexistence issues and means to mitigate such issues, and primary coexistence issues under challenging deployment geometries, among others. This paper provides an update on the trials, giving an overview of their objectives and characteristics, some aspects that have been covered, and some early results and observations
