Overcoming high deployment costs of synchronizing Enterprise Small CellsDavid Chambers
LTE-Advanced features require tight frequency and phase timing to synchronise with other nearby cells and are far more demanding than 3G or even the initial LTE services. This is particularly difficult to achieve indoors where satellite GNSS signals are weak.
Often the deployment costs far exceed those of the equipment where external GPS antenna are used, such as negotiating rental of suitable roof space, cabling for external GPS antennas, installation and ongoing maintenance. Reliance on a single technology also raises availability concerns in case of outage.
This webinar reviews the importance of phase timing and how best that can be achieved for indoor small cells. Microsemi will also introduce an innovative solution that drastically reduces installation and deployment costs while achieving the high precision of frequency and phase synchronisation required.
Presenter: Eric Colard, Director of Emerging Line of Business, Microsemi Frequency and Time Division
Ausgrid is investing more than $1 billion in the Sydney CBD electricity network over five years to 2014. Ausgrid's Sydney CityGrid project involves constructing new substations, replacing and upgrading high-voltage cables and constructing a new tunnel to link into our existing network of CBD cable tunnels. These tunnels connect to form an 8 km ring under Sydney's CBD that interconnects Ausgrid's substations.
To provide a GRN P-25 coverage solution into these tunnels for Ausgrid's maintenance staff presented a challenge. Coverage is provided by utilising 'radio over fibre' repeater technology which rebroadcasts the NSW Government Radio Network from two dedicated base station sites located in two of Ausgrid's substations. Radiating cable, fixed to the ceiling of the tunnel, distributes the radio signals to the user in the tunnel, providing a method of communications deep underneath Sydney's CBD, where previously there was no way of communicating with the outside world.

Qualcomm is elevating its role as a market leader by bringing breakthrough concepts to LTE’s evolution. We believe that the next significant performance leap will come from heterogeneous networks, or HetNets, which bring the network closer to the user through low-power nodes such as pico and femto-cells. LTE Advanced uses adaptive interference management techniques to further improve the capacity and coverage of these HetNets. There by, ensuring fairness among users and an enhanced mobile experience, especially for those users at the cell edge. LTE Advanced also introduces multicarrier to leverage ultra wide bandwidths up to 100 MHz, supporting very high data rates.

Présentation du CogLab par Romain ROUYER
Lieux : Imaginove, au Pôle Pixel, Lyon
Date : Mardi 21 Octobre 2o14
Thème : UI#02 – Brain Computer Interface : Usages et enjeux pour l’innovation et la création
Organisateur : David GAL-REGNIEZ
Animateur : Nicolas NOVA
Anticiper les nouvelles formes d’interaction est un des objectifs des Think-Tank d’Imaginove. Dans l’histoire de l’informatique, l’interaction homme-machine a fortement évolué en à peine 30 ans. De la simple ligne de commande (CLI – Command Line Interface) à des interactions plus complexes et plus intuitives grâce aux interfaces graphiques (GUI – Graphical User Interface) et naturelles (NUI -Natural User Interface), les interfaces à venir font davantage appel aux sens (Perceptual Computing), à l’émotion (Emotional Computing) et à l’interaction avec le cerveau (BCI – Brain Computer Interface). C’est ce dernier mode d’interaction que nous allons évoquer durant ce think-tank. Comprendre ce qu’est la BCI signifie de réfléchir à ce que cette interface s’apparentant à de la télépathie peut apporter comme nouvelles formes d’interaction et signifie plus particulièrement dans notre cas de réfléchir à ce que ce type d’interaction peut apporter dans les usages et dans l’écriture de projets industriels et/ou créatifs notamment dans les domaines du jeu vidéo et des arts numériques.

0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.

The Carrier Ethernet Backhaul Economic Driver
TDM backhaul for 4G is costly and unreliable
• Monthly TDM cost per tower for 10Mbps ~ $20K.
4G builds are capital intensive
• Fiber and microwave costs require significant
investment ($20-$50K per tower)
• Existing tree topologies are cost-inefficient
• Leased services can balance the CAPEX load

Implications of LTE Deployments
Backhaul Market Drivers
Increased bursty data traffic and streaming video
• User Interface Improvements
• Additional cell sites, devices, and increased b/w (10-100x)
• Wildly varying traffic patterns
Rapid deployment is a must
• First to market captures market share (WiMax has a 2-3 yr.
lead over LTE)
• Rapid construction requires multiple strategies for backhaul
deployment (self-build, lease)

Carrier Ethernet for 4G
Operators need Ethernet for:
– Greenfield WiMax deployments
• Opportunities limited today but increasing
• All eyes on successful deployments (Clearwire/Xohm)
– ATM 3G Leapfrogs
• Developing world operators slow to adopt 3G technology
– Wireline Wholesalers
• May have separate PWE3 requirements (e.g. ATT, BT)
– 4G deployments (2-3 yrs from now)
• Evolution to LTE from GSM/UMTS family à 88% of market
• Key is to commence now during transition from TDM to Packet
• Ethernet + T1/E1
– Combined Ethernet + T1/E1 (ATM & TDM) over Ethernet backhaul
– Represent roughly 80-90% of today’s MWB

Key drivers for Carrier Ethernet Solutions
Ethernet is Carrier Class & Cost Less
– Universally accepted that Ethernet is less expensive and ubiquitous technology
– By 2008, 89% of providers believed that Carrier Ethernet is mature enough for
“carrier class” deployments
– Solid Ethernet OAM features that provide a comfort factor for providers (SDH like
characteristics)
– Connection oriented Ethernet (COE) solutions provide deterministic & resilient
services (VLANs, PBB-TE, etc..)
Enterprises & Providers want Ethernet
– Reported growth in the Ethernet services revenue ($14.9B in 2008 to $19.9B in 2011)
– Service Providers have lowered the price per bit for Ethernet services, making it
more attractive than legacy services (TDM, ATM, etc…)
Ethernet is integral to Network Transition
– Ethernet is the key component to many NGN packet network transformations
– COE is well-placed to replace legacy SDH applications
– Evolution of 40G and 100G are being driven by data centre applications and are
complimentary to Optical networks
