Pre 5G Wireless Concepts: DAN Anchor Booster (ID-11)

  • Daniel Moore, Intel Corporation, USA
In this live demonstration, Intel will show LTE and 802.11ad dual connectivity in an “Anchor/Booster” design concept, with 802.11ad taking the place of future mmWave technologies. This pre-5G concept system includes an Intel® XeonTM based test eNodeB, an Intel® XMMTM 7260 LTE modem and an Intel® Tri-Band Wireless-AC 17265 – an 802.11ad product. The demonstration reflects Intel’s unique ability to create a complete pre-5G system that’s fully integrated and optimized from the device to the network, and it is an important milestone in Intel’s plans to develop more advanced solutions on the road the 5G.

Pre 5G Wireless Concepts: LAA/ LTE-U (ID-12)

  • Samuel Wong, Intel Corporation, USA
Intel and the mobile industry are looking at new ways to increase network capacity by extending LTE to unlicensed bands leveraging a mixture of licensed and unlicensed spectrums.
Two versions of such LTE technology that are under discussion are LTE-unlicensed (LTE-U) which is a proprietary standard being considered by operators, and LTE-LAA (License Assisted Access) which is being developed as part of 3GPP standards. The co-existence algorithm implemented for this demonstration is periodic transmission (as defined by the LTE-U forum) on an unlicensed band with variable on/off time to ensure fair use of unlicensed spectrum.
The demo will show adaptation of the coexistence algorithm (on/off period) to varying Wi-Fi AP transmissions to show fair use of unlicensed band, as well as minimal impact on latency sensitive traffic (voice/video) for transmissions scheduled by Wi-Fi AP to associated Wi-Fi STA/clients.

Pre 5G Wireless Concepts: LTE/ WIFI Aggregation (ID-13)

  • Jing Zhu, Intel Corporation, USA
In this demo, Intel will showcase the upcoming 3GPP Release-13 LTE/WiFi Link Aggregation technology and its future extension to integrate a third RAT based on mmWave (e.g. 802.11ad WiGig). Specifically, Intel will demonstrate: 1) Multi-RAT radio resource management / traffic splitting capability on commercial android smartphones. The traffic load will be distributed over LTE and Wi-Fi network dynamically based on continuous real-time measurement and information exchange between WiFi AP and LTE eNB, with zero OTA overhead. 2) Super-high (Gbps) throughput via the third mmWave link, and seamless fallback to the LTE/WiFi link when the mmWave link is lost due to blockage.

Pre 5G Wireless Concepts: Millimeter Wave Backhaul (ID-14)

  • Ali Sadri, Intel Corporation, USA
Beam forming and beam tracking for very large mmWave antenna arrays are among the most challenging areas of wireless research and development for academia and industry. In this demonstration, Intel will show a fully adaptive 128-element Modular Antenna Array (MAA) POC utilizing the commercially available Intel 802.11ad baseband module and a uniquely architected modular antenna array design comprised of 8 individual WiGig radio modules as the access point to connect to a single 16-element WiGig radio module as the user equipment. This demonstration proves the feasibility of MAA system architecture for outdoor access applications and as a candidate for future mmWave systems for 5G cellular networks.

Pre 5G Wireless Concepts: Open Internet Consortium SmatTap (ID-15)

  • Geoffroy Van Cutsem, Intel Corporation, USA
The Open Interconnect Consortium will produce a specification and standard code to discover and connect IoT devices. The demonstration showcases a tablet and phone controlling 3 very different IoT devices as a group: a beer actuator, an LED array, and a music playback system. The demo uses actual, standard OIC APIs to take actions (pour, display, play) and retrieve attributes (temperature, remaining liquid). By extension, any “thing” could be grouped, read and controlled by a smart device using standard API calls. Standardization should accelerate IoT market growth by reducing fragmentation.

A Real-time 20 MHz 128 Antenna Base station Massive MIMO with 12 UEs based on TDD Channel Reciprocity (ID-4)

  • Nikhil Kundargi, National Instruments, United States of America
  • Karl Nieman, National Instruments, United States of America
  • Ian Wong, IEEE, United States of America
Massive multiple-input multiple-output (MIMO) is one of the main candidates to be included in the fifth generation (5G) cellular systems. For further system development it is desirable to have real-time testbeds showing possibilities and limitations of the technology. In this demo we describe the world’s first fully realtime Massive MIMO testbed. It is a flexible testbed where the base station operates with up to 128 coherent radio-frequency (RF) transceiver chains based on software radio technology. Orthogonal Frequency Division Multiplex (OFDM) based signaling is used to serve 12 simultaneous users in 20 MHz of bandwidth. Real time MIMO precoding and decoding is distributed across 64 Xilinx Kintex-7 FPGAs with PCI-Express interconnects.

Real-time Prototyping of 5G Software Defined Networks using National Instruments SDR Platform and the NS3 Network Simulator (ID-17)

  • Vincent Kotzsch, National Instuments, Germany
  • Jaeweon Kim, National Instuments, United States of America
Numerous deployment options are available in today’s networks such as small cells, LTE/WiFi interworking and carrier aggregation that require a lot of network coordination. In the context of 5G new concepts are being discussed such as cloud RAN, mmWave, Massive MIMO as well as ultra-low latency. While many of the concepts mainly affect the complexity of the physical layer and RF, the higher protocol layers including MAC will have to cope with a tremendous set of different requirements e.g. in terms of throughput, latency and traffic scheduling. Therefore, it is not enough anymore to show simulation studies to convince vendors and operators that the promised gains translate into practice when proposing new techniques on top of the existing ones. In particular, for systems with multiple base stations and terminals connected into a network, a real-time prototyping under practical constraints is the key to improve the understanding of new wireless technologies and how they interwork with existing components.
NI’s SDR platform is the most appropriate solution to prove the practical verification of proposed multi-node wireless networks. In this specific demonstration we show the capabilities of combining the NS3 LTE network simulator with the NI LabVIEW PXI / USRP platform to enable real-time prototyping for LTE-Advanced based 5G software defined networks. We will show how the proposed concept can be used for prototyping several important transmission scenarios in LTE-A networks under real wireless channel environment using NI hardware components acting as eNBs and UEs. The challenges we address is how to overcome the increasing complexity of all transmission layers not just an algorithmic level but also rapid prototyping exercise of new advanced techniques used in 5G networks. Furthermore, we will give insight about how the NI LabVIEW graphical system design software is able to address the challenges by providing a common development environment for all the heterogeneous elements in the NI SDR system (i.e., the GPP, RTOS, FPGA, converters and RF components), with tight hardware/software integration and a good abstraction layer.

10Gbps E-band Radio Link (ID-1)

  • Malik Gul, National Instruments, Pakistan
  • Wes McCoy, National Instruments, United States of America
  • Ahsan Aziz, National Instruments, United States of America
The fifth generation (5G) of mobile communication systems aims to provide peak data rates greater than 10 Gbps along with a latency of less than 1 ms. To achieve these requirements, communications in the mmWave frequencies with very high bandwidths (> 1GHz) are a potential candidate. However, designing a radio with several GHz of bandwidth that can support tens of Gbps throughput with sub millisecond latency and with a quality of service guarantee in mmWave bands is very challenging. Therefore, new air interface for supporting wireless access and backhaul in mmWave bands are being researched.
In order to understand the practical challenges and design tradeoffs of realizing such a complex system, prototyping is essential. We will demonstrate a “RF to bits” real-time 2x2 MIMO radio link operating at E-band that supports 2 GHz bandwidth and achieves up to 10.2 Gbps real-time throughput.
It is the first-ever software-defined prototyping platform, which is open and fully modifiable for designing and testing a real-time bi-directional, over-the-air mmWave communication system. The system is fully programmed by LabVIEW. The RF front end of the transceiver supports a carrier frequency between 71-76 GHz with 2 GHz real-time bandwidth. The base-band processing unit consists of FPGA modules and Intel cores running a real time OS. In this demonstration, we will provide an overview of the software architecture, real time signal process algorithms and data exchange across modules. We will also show how the modular software architecture and the signal processing design enable us to switch between SISO and different modes of MIMO system configuration. We will discuss the concept of Wide Data Paths (WDP) signal processing, which allows us to achieve very high throughput and low latency signal processing.

Demonstration of Real-time MIMO Full-duplex Radio with Adaptive Self-interference Cancellation (ID-23)

  • Dongkyu Kim (Senior Research Engineer, Ph. D, LG Electronics Inc.)
  • Kwangseok Noh (Senior Research Engineer, Ph. D, LG Electronics Inc.)
  • Jaehoon Chung (Principal Research Engineer, Ph. D, LG Electronics Inc.)

  • Chan-Byoung Chae (Assistant Professor, Ph. D, Yonsei University)
Full-duplex radio (FDR) transceivers are able to transmit and receive simultaneously at the same frequency band. In wireless communications, the FDR transmission can exploit double spectral efficiency ideally when uplink and downlink share the same band(s) simultaneously. Thanks to this attractive feature, the FDR transmission has become one of key technologies for future 5G wireless communication systems. A major challenge for FDR transmission is, however, reducing inherent self-interference caused by the leakage of the transmitted signal to a receiver chain. In this demonstration, we firstly concentrate real-time multiple-input multiple-output FDR (MIMO-FDR) operation with adaptive self-interference cancellation (SIC) technique, which is targeted to achieve outstanding and reliable SIC performance for feasible MIMO-FDR system. Based on stable MIMO-FDR operation, we also demonstrate real-time high-quality video transmission with MIMO-FDR transmission and compare to that of conventional system with the single-input single-output half-duplex radio (SISO-HDR) transmission.

  • William Thompson, Toshiba Research Europe Limited, United Kingdom of Great Britain and Northern Ireland
We introduce a completely new paradigm for wireless networks, designed to accommodate the increasing density and capacity requirements of networks such as the “Internet of Things”. The concept challenges a series of preconceptions upon which conventional networks are based, and in so doing has the potential to greatly increase efficiency, throughput and reliability, and to significantly reduce latency. We show the concept of wireless multi-terminal and multi-node communications using a Dense Cooperative Wireless Cloud Network (DIWINE) with a massively interacting distributed physical layer infrastructure. The demonstration will showcase key features of the DIWINE concept including Wireless Physical Layer Network Coding (WPLNC), distributed cooperation and synchronisation, and self-organisation using Software Defined Radios (SDR). The demonstration will showcase future Smart Meter Networks (SMN) which will generally be delay intolerant, energy efficient, and require high data-rates thus exploiting the DIWINE paradigm.

The next generation of telecom networks will support a number of diverse vertical industries. Given the economic pressures of the competitive telecom environment, we regard it as unlikely or at least very difficult that a single telecom operator could acquire expertise in all the different vertical domains to ensure an efficient service operation for each and every multitude of those verticals. This means that the 5G network shall appear different to different users, molding itself and its architecture based on the requirements of the vertical it is addressing. In previous work, we proposed a plastic architecture for 5G as a step to a fully programmable infrastructure that can natively support different network architectures. The most important aspect of the plastic 5G network is therefore going to be its mold-ability. This mold-ability means that each user, device and/or applications sees the architecture specifically designed for itself in the network. In this demo we show our implementation of this plastic architecture assuming the use of SDN in the future 5G network.

5G Architecture and 5GPPP (ID-2)

Sapphire North Foyer
  • Simone Redana, Nokia Networks, Germany
  • Bernard Barani, European Commission, Belgium
Mobile networks have become the main communication vehicle for the upcoming connected society. In addition to humans, billions of machines will be connected to the network in the future, yielding a 10.000 traffic increase beyond 2020. However, such traffic increase does not necessarily lead to a similar increase in the revenue of mobile network operators, which need to make very high investments to handle all this traffic. This challenges the deployment of a mobile network that can satisfy the requirements of the society and at the same time is sustainable for network operators.
A fundamental piece to address this challenge is the design of a novel mobile network architecture that provides the necessary flexibility to offer new services in an efficient way and inherently can share or distribute infrastructure resources dynamically, such that operators can increase their revenue through the new services, while leveraging the efficiency of the architecture to do so in a cost-effective way.
Current mobile networks are not well suited to address the above challenge. In 4G mobile networks, large effort was made in making the air interface fully adaptive to changing radio conditions, but lack similar functionality to optimize the network side. Eventually, while current architectures have been very successful in the last few years, they do not provide the required flexibility to cope with the service and traffic diversity required by 5G mobile networks as well as the current trends in terms of topologies.
Such trends (in terms of traffic and topologies) make networks increasingly heterogeneous and require tailored solutions to adapt to each specific scenario and service in an efficient way. The central goal of this demo is to present the ongoing demos activities within the 5GPPP initiatives in Europe related to mobile network architecture building blocks for the 5G era.

The security of the power distribution grid remains a paramount to the utility professionals while enhancing and making it more efficient. The most serious threat to the system can be maintaining the transformers, as the load is ever increasing with the addition of elements like electric vehicles. In this paper intelligent transformer monitoring and grid management has been proposed using SAP HANA. The data engineering is done to use the evolving data from the smart meter & transformer monitors for grid analytics and diagnostics for preventive maintenance. The two tier architecture for hardware and software integration is coupled to form a robust IoT platform for smart grid. The proposal also presents industry standards for data integration. Distribution transformer analytics based on real-time data benefits utilities preventing outages, protects the revenue loss, improves the return on asset and reduces overall maintenance cost by predictive monitoring.

This demonstration presents an end-to-end ecosystem trial of the latest spectrum sharing concepts from Europe and US for mobile broadband. It shows an entire live implementation of the European Licensed Shared Access (LSA) concept that introduces LTE network as an additional licensed user in the 2.3-2.4 GHz band currently used e.g. by incumbent wireless cameras in Finland. Demo shows how the incumbent systems are protected from harmful interference from the LTE with the aid of a Repository for spectrum availability information from incumbents and a Controller for managing the LTE network according to incumbent activity. The demonstration shows remotely how a commercial live LTE network can reconfigure its over-the-air operations with shutting down sectors or decreasing transmission power levels according to incumbents’ activities to protect them from harmful interference. Furthermore, the developed LSA trial is here expanded towards the US three-tier Spectrum Access System (SAS) model that introduces three layers of spectrum usage rights whose upper two layers are shown to resemble the LSA concept.

“Biometric” word makes its more importance in present era of technology. We all want a secure environment for our data. Recently a very popular technology and concept is followed by many Social networking websites this is “Big Data”. A data which is large in volume means in size is called big data many companies like Amazon, Facebook, Google, Twitter and other e-commerce companies and government projects like digital cards maintain the large volume of data. They all maintain a large volume of user database. Security in big data is latest research trend in present era lots of scientists are working on security issues in big data. In this paper we throw some light on how different bio-metric technologies play an important role to maintain and provide security in large data projects.

SDN-Based Security Enforcement in Mobile Networks using VNFs (ID-20)

Sapphire North Foyer
  • Michael Jarschel, Nokia, Germany
  • Marco Hoffmann, Nokia, Germany
In this demonstration, we show the feasibility of dynamically allocating network resources for LTE Evolved Packet Core (EPC) gateways, leveraging the split of user and control plane introduced by Software Defined Networking (SDN) and hosting the control plane as a Virtual Network Function (VNF) in the cloud. The scenario we look at is a user of an operator’s network that uses a tablet device infected with malware. The malware is hidden inside a mobile game the users plays. Nokia’s Mobile Guard security appliance detects the infection using its user plane agent located between SGW and PGW. Typically, at this point the Mobile Guard would issue a warning to the user via SMS or email. However, this would allow the malware to have Internet access until the user reacts to the notification and removes it from the device, which bears the risk of it spreading further or in the worst case disrupting network operation. Therefore, in this demonstration, we leverage SDN’s northbound API to notify the PGW SDN controller of the attack and redirect all traffic coming from the device towards a Nokia appliance in the cloud, which offers an app for the tablet to be cleaned. After the user has downloaded the app and used it to remove the malware from the tablet, the Mobile Guard will instruct the PGW SDN controller to forward its traffic normally again. The PGW-C application running in parallel on the controller and thus the normal operation of the mobile network is unaffected by this.

Robust Sub-Nyquist Cognitive Radio System: We present a sub-Nyquist sampling prototype, based on the modulated wideband converter (MWC) that demonstrates cyclostationary detection, collaborative sensing and joint DOA and spectrum sensing, all performed on the low-rate samples.
Sub-Nyquist Cognitive Radar System: Pulse Doppler radars measure both the targets distance to the transceiver and their radial velocity, through estimation of the time delays and Doppler frequencies, respectively. This digital processing is traditionally performed on samples of the received signal at its Nyquist rate, which can be prohibitively high. Overcoming the rate bottleneck, we propose a sub-Nyquist sampling radar prototype. Moreover, we allow for a reduced time-on-target by transmitting non-uniformly spaced pulses. Last, we pave the way to sub-Nyquist cognitive radar by considering transmitted and received pulses with dynamic support composed of several narrow bands.
A Sub-Nyquist UWB Communication System:We introduce a hardware implementation and demo of a sub-Nyquist Ultra Wideband (UWB) communication system. We employ compressed sensing (CS) techniques in order to exploit the sparse nature of the channel impulse response. The system operates in two phases: rst the channel impulse response is estimated using foldable sampling, followed by data detection of the information. We use the Xampling framework to reduce the sampling rate at the analog to digital converter to 1/10 of the transmitted signal Nyquist rate, during both channel estimation phase and data detection.
