<p>&nbsp;</p>
<p>BUTLER's goal is to integrate current technologies and develop new ones to form a &ldquo;<em>bundle</em>&rdquo; of applications, platform features and services that will bring IoT to life.&nbsp; For this purpose, BUTLER will focus on:</p>
<p>a) Improving/creating<strong><em> enabling technologies</em></strong> to implement a well-defined vision of <strong><em>secure</em>, <em>pervasive</em></strong> and <strong><em>context-aware</em></strong> IoT, where links are inherently secure (from PHY to APP layers) applications cut across different scenarios (Home, Office, Transportation, Health, etc.), and the network reactions to users are adjusted to their needs (learned and monitored in real time).</p>
<p>b) Integrating/developing a new flexible <strong><em>smartDevice</em></strong>-centric network architecture where <strong><em>platforms</em></strong> (devices) function according to three well-defined categories: <strong><em>smartObject</em></strong> (sensors, actuators, gateways), <strong><em>smartMobile</em></strong> (user&rsquo;s personal device) and <strong><em>smartServers</em></strong> (providers of contents and services), interconnected over IPv6.</p>
<p>c) Building a series of field trials, which progressively integrate and enhance state-of-the-art technologies to showcase BUTLER&rsquo;s <strong><em>secure</em></strong><strong>, <em>pervasive</em></strong> and <strong><em>context-aware</em></strong> vision of IoT.</p>
<p>In addition to these R&amp;D innovations, BUTLER and its External Members Group also plan to aggregate and lead the European effort in the standardisation and exploitation of IoT technologies.&nbsp; BUTLER will focus on five different vertical domains: Smart Transport, Smart Health, Smart Shopping, Smart Home and Smart City.</p>

<p>Thanks to advances in wireless communications, embedded systems, and IP networking, Machine-to-Machine (M2M) communications provide a huge opportunity for growth in M2M Service Applications. Future M2M Solutions are envisioned to connect billions of existing and new devices, ranging from high-end smart mobile terminals to low-cost resource-constrained wireless sensors or Radio Frequency Identification (RFID) tags. M2M technologies can be beneficially applied to a broad range of use cases for smart grid, telematics, eHealth/mHealth, vehicular networking and systems, industry control, home automation, and environmental monitoring.</p>
<p>Current M2M markets, however, are highly fragmented. Various vertical M2M solutions have been designed independently and separately for different applications, which inevitably impacts or even impedes large-scale M2M deployment. Today&rsquo;s deployments also pose additional technical challenges in managing large amounts of disparate M2M devices, security guarantee, and service discovery.</p>

<p>Addressing a room full of senior executives from across the wireless ecosystem, Alan summarized the key findings of the company's Vision 2020 project in his aptly-titled presentation: <a href="http://www.interdigital.com/wp-content/uploads/2012/10/InterDigital-at-Broadband-World-Forum_October-2012.pdf" target="_blank">"Towards the Personal Ultra Broadband Era"</a>.</p>
<p>The <a href="http://www.interdigital.com/vision-2020" target="_blank">Vision 2020</a> project builds on the premise that re-imagination... of our wireless world...our physical experiences...our digital economy...is the driving force of innovation today. The pursuit of realizing these "new experiences&rdquo; will push broadband needs to new levels, leading to a bandwidth crunch that will require an ever more complex and &ldquo;meshy&rdquo; network of networks.</p>
<p>Alan went on to say that two tech trends will perhaps shape our wireless future more than any:</p>
<p>1. The relentless move to small and smaller cell technologies and deployments that will create a world of ubiquitous connectivity asset availability.</p>
<p>2. The Cloud, or increasingly pervasive sharing technology - already commonplace in the computing industry, but telecom and wireless are playing catch-up.</p>
<p>When putting it all together, a vision emerges of a wireless world that opportunistically and seamlessly leverages any access resource, any spectrum resource, and any device resource.</p>

Three separate speakers presented the company&rsquo;s advanced solutions for the next generation of wireless:</p>
<p><strong>Policy-driven bandwidth management</strong> techniques that factor in various conditions to enable a user&rsquo;s data to be routed over a cellular or Wi-Fi&reg; network &ndash; dynamically switching between networks, combined across several networks to aggregate bandwidth, or segregate multiple applications simultaneously among several networks. While fully transparent to the user, these innovations significantly improve network capacity and make quality of service more predictable.</p>
<p><strong>Advanced waveforms</strong> that achieve high throughput performance in non-contiguous and opportunistically available frequencies &ndash; centered around filter bank multicarrier modulation and its variations - whereby prototype filters are designed to achieve certain frequency and time domain localization.</p>
<p><strong>Dynamic spectrum management</strong> for harvesting additional capacity from TV white space and under-utilized frequency bands to supplement existing cellular and Wi-Fi systems. The company&rsquo;s comprehensive dynamic spectrum management technologies address more efficient utilization of the finite resource that is spectrum &ndash; a critical new frontier.</p>

<p>Putting theory into practice, the company also featured a live demonstration of its Smart Access Manager (SAM), a policy-driven client that enables smartphones, tablets and other wireless devices to make intelligent traffic management decisions using Wi-Fi, 3G and LTE networks. The SAM client dynamically directs traffic flows by type of application, resulting in optimized connectivity and enhanced service provider visibility and control. Its availability on Android and Windows platforms provides MNOs, MVNOs and device OEMs with the ability to offer seamless and secure policy-driven Wi-Fi handover as a differentiator &ndash; a key capability given the increasing use of mobile devices for data-rich applications such as streaming video.</p>
<p>VTC2012-Fall was held 3-6 September 2012 at the Qu&eacute;bec City Convention Center in Qu&eacute;bec City, Canada. This semi-annual flagship conference of the IEEE Vehicular Technology Society brought together individuals from academia, government, and industry to discuss and exchange ideas in the fields of wireless, mobile, and vehicular technology. The event featured world-class plenary speakers, tutorials, and technical as well as application sessions.</p>

This trend is expected to continue for at least the next decade and has even accelerated in recent years as a greater proportion of the population adopts wireless devices with ever greater capabilities such as tablets supporting HD video. To meet this demand, more spectrum has been added and spectral efficiency has improved, but spectrum re-use has been by far the most popular means to add network capacity, i.e., small cells. The shorter link distances that come with smaller cells combined with recent advances in millimeter wave transceivers and antennas, open the door for the use of millimeter wave spectrum in cellular systems. The huge bandwidths available and high directivity of antennas at millimeter wave frequencies offer the potential for greatly increasing network capacity without cell sizes becoming impractically small, but there are also great challenges.</p>

<p><img class="alignnone wp-image-2501" title="PC at Policy" src="http://www.interdigital.com/wp-content/uploads/2012/08/PC-at-Policy.jpg" alt="" width="152" height="133" /></p>
<p>Dr. Chitrapu discusses how policy enforcement beyond the core network further enhances user experience and network performance.</p>
<p>The Policy Control Conference - held this year in Amsterdam, April 24-25 - has been growing in size: Policy Control and real time charging is definitely an important area to operators.&nbsp;InterDigital was one of the event&rsquo;s sponsors and Dr. Prabhakar Chitrapu (Senior Principal Engineer, InterDigital) presented on the company&rsquo;s Smart Access Manager solution and mobile offload via policies on the server and the device.&nbsp;</p>
<p>The big talk at the conference was around value-based services, especially video. Although operators have started moving away from tiered pricing, it seems like many believe that they are not moving fast enough to offer bundled packages and attempting to offer/price value-added video-based services.</p>
<p>Other value-based examples include multiple devices (e.g. smartphones and tablets), tethering, happy hour, turbo boost, zero charging for specific websites/services, roaming packages, and multiple subscriptions.</p>
<p>Video over wireless is growing every day, and you can tell from the Policy Control conference that operators are thinking hard about how to handle it, deliver it, and manage it.</p>

<p><img class="alignleft size-full wp-image-3492" title="Video-Aware white paper" src="http://www.interdigital.com/wp-content/uploads/2012/10/Video-Aware-white-paper1.jpg" alt="" width="150" height="95" />The demand for wireless data is growing rapidly, with a substantial component of this growth due to the proliferation of multimedia traffic (and in particular video applications) delivered to smartphones over Wi-Fi&reg; and cellular data networks.&nbsp; Real-time <a href="http://www.interdigital.com/video" target="_blank">video over wireless</a>&nbsp; is expected to become a bigger component of the overall multimedia traffic as LTE begins to enable the use of video conferencing over cellular networks.&nbsp; This growth will outpace the capacity of wireless networks and will necessitate the use of more &lsquo;out-of-the-box&rsquo; approaches to managing the data onslaught.&nbsp; In particular, cross-layer optimization of the wireless networks to exploit the unique nature of video traffic as well as optimization of the video applications for transport over today&rsquo;s congested wireless networks can deliver substantial gains in both network efficiency and user perceived Quality of Experience (QoE).</p>
<p><a href="http://www.interdigital.com/wp-content/uploads/2012/10/Video-Aware-Link-Adaption-White-Paper_InterDigital_Oct2012.pdf" target="_blank">The InterDigital white paper, titled Video-Aware Link Adaption</a>, describes several ways in which the performance of video delivery may be enhanced through cross-layer optimization, making the underlying networks aware of the applications they are supporting and making the applications aware of the networks on which they are running.</p>
<p>The paper outlines two cross-layer approaches to video performance optimization over LTE networks that leverage the structure of real-time video in performing link-adaptation in the MAC/PHY layers at the basestation (Class 3).&nbsp; These approaches include adaptation of Hybrid-ARQ (HARQ) retransmission as well as multi-user scheduling to improve overall user QoE and network efficiency.&nbsp; These techniques may provide very meaningful improvements in the end user&rsquo;s perceived QoE (more than 4dB PSNR) while requiring minimal changes to the network.</p>
