InterDigital’s 5G vision
Wednesday 05 September 2012, 11:00–12:30 (208AB)
This InterDigital vision presentation will touch on new thinking in wireless evolution to fulfill personal ultra broadband on the go target for the next decade. This talk will delve into new strategies to address the bandwidth crunch and why we need them. We will start off what the past tells us about where we are going tomorrow and moves on to understand why small cells and Wi-Fi are so important in a winning strategy. InterDigital Wireless2020 vision details mobile broadband technology enablers for 2020 and beyond.
1. Bandwidth management - The focus of this presentation the Bandwidth Management solution that takes advantage of multiple heterogeneous access technologies by not only allowing for seamless IP flow mobility between a Wi-Fi Access Point (AP) and a cellular small cell, but by also allowing for aggregation to simultaneously use Wi-Fi and cellular technology. InterDigital's 'Bandwidth Management Solution' is a fully integrated IP layer based software/gateway at the 'edge network' that supports policy based broadband traffic management in a heterogeneous network deployment such as cellular and WiFi.
2. Advanced waveforms - One of our research projects is to identify and develop waveforms that achieves high throughput performance in non-contiguous and opportunistically available frequencies. Our focus has been on filter bank multicarrier modulation and its variations, in which prototype filters are designed to achieve certain frequency and time domain localization.
3. Dynamic spectrum management - The ALTESS DSM wireless communications system (based on 3GPP LTE Release 10) is designed to efficiently operate in both licensed and license exempt or specifically TVWS spectrum. Key features include the ability to aggregate spectrum across both licensed and TVWS spectrum, sensing to monitor and dynamically switch TVWS channels in response to the detection of primary users and/or interference from secondary users, an interface to the co-existence database to assess the available TVWS channels, and mechanisms to co-exist with other secondary users like Wi-Fi.
Accelerating Wireless Applications Waveform Design, Implementation and Validation using Model-Based
Wednesday 05 September 2012, 14:00–15:30 (208AB)
Today’s 4G networks and next-generation broadband internet access systems have become exceedingly complex. The underlying communication waveforms must meet ratified specifications in operating environments, a feat that theoretical simulations alone cannot achieve. For that reason, there is a need to test on real-life hardware. This implies migrating theoretical models to physical platforms. This migration process pose significant challenges to designers, engineers and scientists. At the same time, ever shrinking
time-to-market constraints put significant pressure on the design teams.
A model-based design approach speeds up the whole design chain from simulation to implementation, tests and validation. This workshop intends to demonstrate the usefulness of the model-based approach through the model-based implementation of a 2x2 QAM16 OFDM PHY layer transceiver. Initiated from simulation, the implementation finally runs on an FPGA-based hardware and transmit/receive over an air interface. During this session, the following skills will be developed by attendees:
- Simulation of FPGA-based systems on a Simulink environment;
- Co-simulation of FPGA-based systems with original host simulation model;
- Long-term Record-Playback tools enabling working on test vectors;
- Speeding up algorithm development trough real-time parameters adjustment;
- Implementation on real FPGA-based hardware, using a model-based design approach.
RF Test and Measurement: Connector Care and Computer Connectivity
Wednesday 05 September 2012, 16:00–17:30 (208AB)
Research and Development in RF and microwave technologies often includes a test phase which involves making practical measurements on prototype systems or devices to compare theoretical data to actual test results. This means utilizing specialized test and measurement instrumentation. Two aspects of this include connecting to the device under test and gathering test data to a computer. This tutorial will contribute to developing skills in:
- Connecting to and protecting the connectors and cables used in interfacing the electronic instrumentation to the device or system being tested. This will help ensure that measurement results are valid and that no damage occurs to the instrumentation in the process of connecting with your device or system.
- Establishing communications between the instrumentation and your computer using GPIB, VISA, LXI, SCPI, IVI Drivers and the concept of Command Expert for the purpose of automating test and collecting test data. This is an essential precursor to developing your automated test programs using tools such as Agilent VEE, MatLab, Labview, Visual Basic, etc.
