As presented at the 4G Wireless Evolution conference in Miami, January 22, 2010. WiFI has been at the heart of the change to OFDM and MIMO solutions. It is not suprising that WiFi is a hotbed of innovation in today’s marketplace. This discussion looks at the current and future opportunities associated with WIFI and the implications for new kinds of deployment and adaptation by the LTE and WiMAX community.

Wi-Fi Opportunities In A 4G World

Brough Turner

Brough’s keynote address at the October 2010 4G Wireless Evolution Conference. In it, he argues: 1. All key 4G technologies are pioneered by Wi-Fi (3-5 year lead!). 2. Wi-Fi will be the dominant solution for mobile data offload. 3. 4G technologies represent a wireless tipping point with the result they will revolutionize backhaul and eventually the first mile (via wireless ISPs). He closes with two slides on his new wireless ISP, netBlazr.

Hadoop: A Hands-on Introduction

Claudio Martella

The Biodiversity Heritage Library (BHL), like many other projects within biodiversity informatics, maintains terabytes of data that must be safeguarded against loss. Further, a scalable and resilient infrastructure is required to enable continuous data interoperability, as BHL provides unique services to its community of users. This volume of data and associated availability requirements present significant challenges to a distributed organization like BHL, not only in funding capital equipment purchases, but also in ongoing system administration and maintenance. A new standardized system is required to bring new opportunities to collaborate on distributed services and processing across what will be geographically dispersed nodes. Such services and processing include taxon name finding, indexes or GUID/LSID services, distributed text mining, names reconciliation and other computationally intensive tasks, or tasks with high availability requirements.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

Dubai, often portrayed as a shimmering oasis in the desert, faces its own set of challenges, including the occasional threat of flooding. Despite its reputation for opulence and modernity, the emirate is not immune to the forces of nature. In recent years, Dubai has experienced sporadic but significant floods, testing the resilience of its infrastructure and communities. Among the critical lifelines in this bustling metropolis is the Dubai International Airport, a bustling hub that connects the city to the world. This article explores the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.
