Behind the WiFi Network @ Mobile World Congress 2014: Site Surveys

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.

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.

Behind the WiFi Network @ Mobile World Congress 2014: Setting the Stage

Every year a new attendance record is set at Mobile World Congress by networkers participating from over 200 countries across the globe. This grand attendance of industry-defining vendors, technology enthusiasts and exhibitors triggers an explosive growth in the number of Wi-Fi capable devices being brought to the event. For MWC 2014, Cisco partnered with Fira Gran Via and GSMA to pull off one of the most successful high density Wi-Fi network deployments in the history of global tech events. This blog kicks off a series to provide a glimpse of behind the network, into the design stages, and the course of actions undertaken to implement a robust high density wireless network which served more than 22,000 concurrently connected unique devices and a total of 80,880 devices throughout the event. Full details in whitepaper here.

Setting the Scene

Divided into eight massive exhibition halls, Fira Gran Via covers around 3 million square feet (280,000 square meters) of area which also includes outdoor areas, restaurants, conference rooms, network lounges and a continuous elevated walkway flowing through the entire venue. Higher the environmental complexity, the more fun and challenging it is to achieve the right wireless design for a pervasive network that meets all the needs.

Generally, the physical design of large convention and exhibition halls bear an impish knack of unfavorable conditions for a ubiquitous high density Wi-Fi network, owing mostly to the lofty ceiling heights and construction components. Read More »

Not All 802.11ac AP’s are Created Equal: Demand the Full Story

It’s always interesting and often entertaining to observe how competitors promote their products and what they choose to focus on—and more importantly, what they choose not to focus on and what they hope people won’t ask questions about.

Consider yet again how a competitor chooses to position their “purpose built” AP vs. the Cisco Aironet 3700 802.11ac Access Point Series.

This competitor frequently (and somewhat obsessively) points out that its 802.11ac AP has dual “active” 800 MHz cores while the Cisco AP3700 has only one “active” 800 MHz core. This is not completely true since it completely overlooks the fact that the Cisco AP3700 also has a dedicated CPU core and DSP for each radio subsystem.

Furthermore, it also overlooks that the dual “active” cores in the competitor’s AP share 512 MB of DRAM. The single “active” core of the AP3700 has dedicated 512 MB of DRAM. Also each radio subsystem has a dedicated 128 MB DRAM (for 768 MB total DRAM in the AP3700).

Small Business Profile: Auto Union Tuning

Hello all,

IMG_2031

Out here in Southern California, in a town called Huntington Beach, is a growing Auto Shop called Auto Union Tuning.

It is a special place where the owners, Dave and Raz specialize in car care, maintenance and tuning of VW, Audi and Porsche automobiles. On any day, you will find a combination of these three car makes on the lifts and in the garages. From quick VAG-com checks to complete engine rebuilds, you name it, this shop can take care of most work.

There is one specific car they specialize in is the Audi B5 S4. This particular model is sought after by Audi enthusiasts for the tuning potential. This S4 was manufactured between 1997 and 2002, which sported a twin-turbocharged 2.7 liter inline 6 cylinder engine. Some key upgrades can make a 10+ year old car beat new Nissan GTR’s, Supercharged BMW M3’s, Supercharged Corvette’s, Vipers, Shelby’s etc. down a quarter mile.

But alas, that is another story.

I first met Raz back when I was in search of someone to work on my own B7 Audi S4 Avant. Thankfully, I met Raz and he worked on my baby until I sold her to a gentleman that flew out from Salt Lake City and bought my Audi S4 site unseen. This largely because of a conversation I recommended my buyer to have with AUT. Yes, AUT did a good job not only maintaining and caring for my then car. But it is the countless other AUT customers who told others about their experience in how AUT handled their customers and their customers cars. Simply, the they did a great job in running a great business. In the few years I have known the owners, I have seen their business being born, move into a small shop, expand into neighboring units, then move into their current facility, which I must say, is impressive.

The Lifts

With all of this growth, Raz and Dave has seen their network needs and requirements evolve. At first, basic network connectivity using a consumer all-in-one router did it’s job obediently for the first few years, but once they moved into the new facility, things had to change. Simply, the networking strategy had to grow up.

Fast Forward to today, there’s now a total of two new mechanics, office employees, three new workstations and a new ticket writing software that needs to be available on multiple workstations. No doubt new employees and more requirements on their network will be coming in the future.

Yes, Raz and Dave have planned for growth. The new waiting room and front office now houses new couches and a TV. New wheel displays are set-up, vendor banners are hung, and the walls are newly painted.There is a bunch of exhaust and performance parts displayed around the room.

But this planning also included a new need for wireless guest access and of course a secure network where Auto Union Tuning Employees can access secure files and applications, such as the new ticket software. With some discussion, and some assistance, Team AUT procured new Cisco Small Business product, including one of Ivor’s 300 Series PoE Managed Switches, and a pair of Nasser’s WAP551 wireless access points. All of the workstations are hard-lined into the 300 Series Switch, and the WAP551’s are set-up and deployed with a guest network and secure internal network and they are now providing blazing performance in the office and garage workspaces. The entire deployment was said to be under 30 minutes. Much of the time savings was due to the WAP551’s Single Point Setup. The team has some cleanup work, cable management, mounting the wireless access points, but most of the heavy lifting work is complete. The AUT Team is happy with the new network and greeting new customers every day.

Auto Union Tuning’s Owners: Raz and Dave

Auto Union Tuning is but one example of how a small business can literally take off from day one and transform and evolve into a growing, thriving business. With honest, good old fashioned hard work comes success and growth. With this growth comes the necessity for it’s networking infrastructure to be flexible and scalable.

We think you will find that the Cisco Small Business portfolio fits this model rather well.
