Big Data is one of the most talked about topics of today across industry, government and research. It is becoming the center of Investments, Innovations and Improvizations (3I’s), and no exaggeration to say that Big Data is Transforming the World. Considering it’s potential the IEEE Computer Society is conducting the IEEE International Conference on Big Data 2013, a premier forum to disseminate and exchange the latest and greatest in Big Data. The main theme of the conference will be the 5V’s: Volume, Velocity, Variety, Value and Veracity aspects. The conference will take place in Santa Clara, CA from October 6th to 9th. I have the great privilege to co-chair the Industry and Government Program with my distinguished colleagues: Rayid Ghani (Obama Campaign), Wei Han (Noah’s Ark Lab) and Ronny Lempel (Yahoo! Labs) along with Xiaohua Tony Hu (Drexel University) who is chairing the Steering Committee. The 4-day program includes about 50 presentations selected from over 300 paper submissions from more than 1000 authors from 40 countries, four keynotes (Amr Awadallah, Mike Franklin, Hector Garcia-Molina and Roger Schell), 12 workshops, and two tutorials. I have the great pleasure to deliver the opening and welcoming speech on behalf of the industry and government committee. I am also chairing Amr Awadallah’s keynote session on Key Usage Patterns for Apache Hadoop in the Enterprise and co-presenting a paper titled A Look at Challenges and Opportunities of Big Data Analytics in Healthcare at the workshop on Big Data in Bioinformatics and Healthcare Informatics. This workshop will be very interesting with sessions like Big Data Solutions for Predicting Risk‐of‐Readmission for Congestive Heart Failure Patients, Colon cancer survival prediction using ensemble data mining on SEER Data etc.
Cisco is a proud sponsor of the conference. Additional Information:
If you recall, back in the early days of 802.11n, the Wi-Fi Alliance (WFA) rolled out the 802.11n certification program in phases. Here we are several years later and in that same fashion, the WFA has split the IEEE 802.11ac specification into two certification phases: Wave 1 and Wave 2.
Last week we announced the availability of our 802.11ac Wave 1 Module for the 3600 Access Point and along with that, our intention to develop an 802.11ac adaptive radio module that will support the second phase of 802.11ac, or Wave 2. Most of the 802.11ac discussion in the last year has been focused on Wave 1, so we want to kick off the conversation about the second phase, Wave 2.
If Wave 1 promises increased wireless performance to address the increasing demand for higher performance including growing number of clients demanding higher performance for applications such as HD video streaming, then Wave 2 will stun you with its ability to provide even more throughput beyond the 1.3Gbps that Wave 1 provides as well as a number of other features that will further improve wireless connectivity. It is like taking a really good rock song and adding more cowbell to it.
SNL jokes aside, with the additional features packaged in Wave 2 comes the opportunity for further innovation in Cisco’s Wireless portfolio. We feel that it is important to stay ahead of the technology curve so that customers can plan and benefit from these advances sooner rather than later. So let’s discuss what features are coming with 802.11ac Wave 2. Read More »
The question isn’t IF your users will need more bandwidth, but WHEN they will need more bandwidth. 802.11ac represents the next evolution of the 802.11 standard, and, as you’ve heard, this one really pegs the gas petal in the quest for speed. Offering a link-rate of up to 1.3Gbps, 802.11ac represents the first wireless standard that surpasses the gigabit barrier.
But what makes 802.11ac unique isn’t just bandwidth. The new standard represents a forced push to the cleaner 5GHz spectrum, as well as extended battery life, made possible by getting devices on and off the air more quickly. To learn more about the technical details under the hood of 802.11ac reference this whitepaper.
Cisco’s Aironet Access Point 3600 and an alpha version of the 802.11ac module were demonstrated during Cisco’s presentation during Wireless Field Day 3 (the demo occurs at timestamp 15:30 in the video). Keep in mind that this is a demonstration of a pre-released product so it is expected that throughput and functionality will change and likely increase when the product is available for customers in early 2013.
The test goal was to measure one client, one Access Point 802.11ac performance and leveraged Ixia’s IxChariot to generate UDP traffic over the air. The test was done in an open real world environment, so the achieved throughput is less than what would be expected in a clean RF environment typical of a benchmark test.
Microsoft will launch Windows 8 in late October. Along with a slew of other features, it will be among the first to support the 802.11w standard to protect Management Frames for client devices on Wi-Fi networks.
Customers running old Cisco unified releases (between 4.2 to 7.2) in local, Flex or mesh mode will run into an interoperability bug (CSCua29504, to be exact) that prevents 802.11w enabled clients from connecting to a Cisco WLAN with Management Frame Protection (MFP) enabled. This bug does not affect customers running autonomous access point deployments or customers running Cisco unified releases older than 4.2.
What are the possible solutions for you?
1. Please upgrade your production environment to one of the following releases, which will interoperate with Windows 8.
2. Roll back to pre-windows 8 drivers as identified in the Microsoft Knowledge Base article.
3. Fall back to TKIP
4. Sign up for a beta release for Cisco’s upcoming feature release 7.4 (beta available now!) that supports the 802.11w feature in local mode.
We released our latest in the Fundamentals series earlier this month and it is trending quite well. The 802.11ac standard sounds like a step backwards alphabetically…but it will soon be an incredible step forward forward for WiFi once it is ratified by the IEEE. Watch this latest fundamentals to get comfortable with the truth. 802.11n is still your best bet for 2012 and into 2013 as we continue to partner on the standards process but the future is bright indeed!
