Citizen's Broadband Radio Service enables micro-operators to provide Industrial automation

This demonstration shows how CBRS spectrum sharing can be utilized by a micro-operator to deploy a mobile network for Industrial Internet in a factory environment. We will showcase the ability to identify and capture spectrum at a targeted geographical area combined with the ability to enable usage of that spectrum at the needed service level for the use case as a Service. Spectrum sharing with Citizen's Broadband Radio Service (CBRS) opens the 3.5 GHz band for innovative communication use in the USA. Micro-operators operate mobile networks in a limited area like hospitals, malls, sports arenas, campuses, or factories. Machinery, robotics, control, and sensors are integrated by Industrial automation in factories and other industrial establishments.

The demonstration implements the latest CBRS specifications of Federal Communications Commission (FCC) and Wireless Innovation Forum (WInnF). Spectrum Access System (SAS) and Domain Proxy (DP) communicate according to Spectrum Access System (SAS) - Citizens Broadband Radio Service Device (CBSD) Interface Technical Specification. SAS protects the incumbents by fulfilling Requirements for Commercial Operation in the US 3550-3700 MHz Citizens Broadband Radio Service Band. The functionality is verified with the methodology described in CBRS Architecture Test and Certification Specification.

The demonstrated Network as a Service (NaaS) deployment consists of commercial Long Term Evolution (LTE) User Equipment (UEs), eNodeBs operating as Citizen's Broadband Service Devices (CBSDs), and virtualized hosted Evolved Packet Core (EPC).  The implemented programmable cognitive network operating system is based on commercially available Network Management System (NMS), Self Organizing Network (SON) and Mobile Edge Cloud (MEC) platforms. Domain Proxy and SAS are prototypes of possible future products. The LTE network is installed in the Nokia factory in Oulu, Finland. It is operated under General Authorized Access (GAA) regime on 3.5 GHz band. The incumbents are created for the demonstration purpose, and their information is brought to SAS in the same format as specified by FCC and WInnF. The system can be operated and monitored remotely. The demonstrated user interfaces include views of the system monitoring.

The demonstration verifies architecture, protocol, interference protection, and testing specifications of FCC and WInnF within the implemented functions. It shows interoperability between a Domain Proxy - CBSD provider and a SAS provider. The demonstration confirms the integration between a commercial mobile network and a CBRS spectrum sharing system. The industrial network installation shows the feasibility of CBRS for micro-operators in vertical markets engaged in industrial automation that belongs to one of the most potential break-through business cases for CBRS.



Deterministic and cognitive wireless communication  system with jamming-resistant capabilities for tactical or  industrial communications

This work presents a jamming-resistant and deterministic wireless communication system, which is intended to be used in tactical or industrial communications. These kind of applications require data communication to be bounded in the time and reliability domains, no matter which is the harshness of the environment or the presence of malicious interferences. In harsh propagation environments, communication systems suffer from severe signal degradation, including delay spread, deep fading and Doppler spread. Besides, they must also deal with other system’s interference and jammer attacks.

Unfortunately, traditional wireless communication systems are not able to overcome all these difficulties and, at the same time, fulfill with the aforementioned requirements. As a consequence, it is necessary to deploy new wireless communication systems like the one presented in this work, based on cognitive radio technology. The proposed wireless communication system, shown in Fig. 1, is based on a custom Orthogonal Frequency Division Multiplexing (OFDM) modem design which has been implemented on the programmable logic of a Xilinx Zynq Field Programmable Gate Array (FPGA). The modem is fully customizable, in case it is needed to add new features, and it is similar to the IEEE 802.11a/g physical layer standard. On top of this modem, a deterministic, real-time and cognitive Medium Access Control (MAC) layer has been implemented and evaluated. Based on a Time Division Multiple Access (TDMA) MAC, which ensures deterministic communications in the absence of interference, cognitive capabilities have been added. Unlike traditional cognitive radios, which are used in order to enhance spectrum utilization, the presented wireless communication system is able to detect interference (malicious or coming from other wireless communication systems) and switch the communication to an unoccupied and safe frequency band. Simulations in OPNET and measurements on real hardware have been carried out, which demonstrate the capability of the system to guarantee deterministic data delivery time even in the presence of interference.

A test setup has been prepared with the communication system configured with a frame length of 3.85 ms and a data lifetime of 30 ms. Besides, a jammer generating interferences has been added. In an scenario in which only the frequency the communication system is working is interfered, a single frequency hop is forced and a recovery time bounded between 8.5 and 12.5 ms is achieved. If both, the frequency in which the communication system is working and the one into the first hop is performed are interfered, thus forcing two frequency hops, the achieved recovery time is bounded between 20 and 23.7 ms. In both scenarios the 30 ms data lifetime is fulfilled.

Embracing SCA 4.1

The SCA is a powerful and proven framework for the deployment and execution of signal processing applications on heterogeneous platforms. After a major upgrade to the SCA specification, companies are now evaluating migration from SCA 2.2.2 to SCA 4.1. During WInnComm – Europe 2017, NordiaSoft will present a detailed comparison between the two versions of the SCA specification, including a variety of metrics that will highlight the numerous benefits of using SCA 4.1.


In this “Embracing SCA 4.1” tutorial, NordiaSoft will showcase its new Embedded Components (eCo) Suite for SCA 4.1 development, where alternatives for SCA 2.2.2 to SCA 4.1 migration will be presented. For current users of NordiaSoft software, the tutorial will include a migration example that highlights the usage of the powerful eCo Architect Zero Merge code generation engine that enables the replacement of SCA 2.2.2 infrastructure code with new SCA 4.1 code without affecting the application specific business logic. The tutorial will also include a migration example where SCA models, source code, components and applications are automatically generated from SCA XML Domain Profiles created manually or assisted by proprietary or third party tools.

Physical and data link layers implementation of the NATO NBWF

There is currently no narrowband Combat Net Radio (CNR) STANAG waveform for international and combined missions providing interoperability in Network Centric Operations (NCO). The principal objective of the NATO Narrow Band Waveform (NBWF) is to achieve coalition interoperability within lower tactical levels. The NBWF uses bandwidths of 25 KHz and 50 kHz with on-air bit rates up to 82 kbps in the very high frequency (VHF) or lower ultra high frequency (UHF) bands with continuous phase modulation (CPM). CPM has the advantages of high spectral efficiency due to the phase continuity and high power efficiency due to the constant envelope. However, CPM has the disadvantage of the high implementation complexity required to build an optimal receiver. CPM has been used in several well-known communications protocols such as GSM and Bluetooth.
The demonstration shows a physical and data link layers implementation of the NATO NBWF. Comparing with the literature on NBWF receiver implementations, this implementation uses a low-complexity generic receiver for the different modes of the NBWF. An innovative approach concerning coarse and fine frequency, phase and time synchronizations and demodulation is presented. This approach minimizes and simplifies the receiver,
which is important in military portable equipment.
The low-complexity generic receiver for the different modes of the NBWF has been successfully implemented in C++ using open-source libraries (Qt, UHD, IT++, GStreamer) and tested on Odroid-XU4 single board computers attached with a USRP B205-mini software defined radios. The NBWF physical and data link layers are able to run in real-time on these general purpose processors (GPP) owing to the low-complexity generic receiver, this would have not been possible with maximum-likelihood receivers implemented using Viterbi or iterative algorithms.
