In my last blog I discussed setting the stage in preparation for the Wi-Fi network for Mobile World Congress 2014 which supported more than 80k devices over a span of 4 days. Today I’ll talk about one of the many site surveys we conducted at the Fira Gran Via to ensure the success of our high density network. Full details in the white paper here.
High Density Wi-Fi deployments and site surveys go hand in hand. Pre-installation and post-installation site surveys account for the most effective way to identify the contours of your RF coverage and eliminate potential multipath distortions, hidden nodes, and other coverage issues. Special attention was given to the large keynote auditorium halls in order to keep a check on the additional RF coverage needs to accommodate the high density of users packed in a very close range.

Site Survey analysis used to measure the RF coverage in Hall-4 keynote auditorium
The Hall-4 auditorium was one example of such a high density area with the 2000 person capacity area had a peak connection of 1924 concurrently connected Wi-Fi devices distributed across 16 Cisco APs while the Facebook keynote was in progress, with a max load of 530 Mbps of internet traffic. To avoid an RF overlap, the ceiling mounted APs above the auditoriums were converted to monitor mode. Using the final pre-keynote site survey data, the RF profile for the Hall-4 auditorium was tweaked, and RRM automatically optimized the coverage to the desired degree by adjusting the Tx power levels.

“The FCC, under the leadership of Chairman Tom Wheeler, has taken a vital first step toward E-rate modernization and reform today.”
It’s critical that we modernize and reform the E-Rate program to connect all classrooms across the country to high-speed wireless broadband within five years. Today’s order, which provides an additional $2 billion toward Wi-Fi networking in classrooms over the next two funding years, represents a significant down payment on this goal. Importantly, the FCC is prioritizing connectivity for students and teachers in the classroom via Wi-Fi for the next two years, with the intention of continuing that funding into the future. It will also help connect rural schools, while mitigating bureaucracy and red tape that impact the ability to quickly deploy the technology schools and libraries need.
To compete and succeed in the global marketplace, our students and teachers need to have access to the world’s libraries, scientific discoveries, and innovative educational tools at their fingertips. That’s where E-rate comes in. E-rate is the foundation for Internet access in public schools and libraries across America. Read More »

Today’s security challenges are real and significant. We want governments to detect and disrupt terrorist networks before they inflict harm on our society, our citizens, and our systems of government. We also want to live in countries that respect their citizens’ basic human rights. The tension between security and freedom has become one the most pressing issues of our day. Societies wracked by terror cannot be truly free, but an overreaching government can also undermine freedom.
It is in this context that I want to offer some thoughts on actions by the US Government that in Cisco’s eyes have overreached, undermining the goals of free communication, and steps that can be taken to right that balance, and I do so on behalf of all of Cisco’s leadership team.
Confidence in the open, global Internet has brought enormous economic benefits to the United States and to billions around the world. This confidence has been eroded by revelations of government surveillance, by efforts of the US government to force US companies to provide access to communications of non-US citizens even when that violates the privacy laws of countries where US companies do business, and allegations that governments exploit rather than report security vulnerabilities in products.
As a matter of policy and practice, Cisco does not work with any government, including the United States Government, to weaken our products. When we learn of a security vulnerability, we respond by validating it, informing our customers, and fixing it. We react the same when we find that a customer’s security has been impacted by external forces, regardless of what country or form of government or how that security breach occurred. We offer customers robust tools to defend their environments against attack, and detect attacks when they are happening. By doing these things, we have built and maintained our customers’ trust. We expect our government to value and respect this trust.

You don’t need me to tell you to know that we are in the midst of a technology revolution. It’s mobilizing the internet. And it’s transforming the way billions of people around the globe collaborate, communicate, and connect to the internet.
• The education customers I work with are incorporating video and mobile applications into their curriculum with up to a 100 students in an auditorium accessing the Wi-Fi network simultaneously.
• Healthcare customers are relying on Wi-Fi to connect patients, devices and provide nurses instant access to medical records.
• Manufacturing customers are increasingly using Wi-Fi to enable workers on the factory floor to have real-time video conversations with experts anywhere in the globe.
What do these things have in common? They all depend on Wi-Fi for connectivity. In these areas, and so many more, Wi-Fi has become a central way that people access the Internet.
The FCC released a historic decision on April 1, 2014 (adopted March 31)with regards to the use of 5 GHz spectrum. Although there were many technical aspects included within this decision, one of the most interesting was making the 5150-5250 MHz U-NII 1 band available for outdoor WLAN use. Read More »

Cisco Live Milan 2014 kicked off this morning with an opening keynote by Rob Lloyd. During the session Rob shared Cisco’s vision of the Internet of Everything, and explored the industry trends and technologies that are making that vision a reality. One of these areas is enabled by Cisco’s CMX solutions and our growing ecosystem of partners.
To illustrate how this vision is becoming a reality, a CMX demo was shown on stage. The demo related to a wine producer ( we are in Italy by the way..) who was able to engage with their customers via their mobile app. Enabling the customer find the particular wines they are interested in, interact with the wine maker, get location specific promotions and really deliver a highly personalized and location specific service.
