Customer Perspective: 5 Retail Trends Driving Wi-Fi

This is the type of post that gets me excited. Today, I’m happy to feature a special customer guest author: Andrew vonNagy, CCIE #28298 (Wireless), and currently Technical Architect for a Fortune 50 retail company. Many of you may know Andrew from his active blog, Revolution Wi-Fi,  or his Twitter feed: @revolutionwifi. Stay with us over the next two weeks as Andrew offers his take on the intersection of Retail and the Wireless LAN industry.

Retail Wi-Fi networks have long been dominated by inventory management applications and services that enabled a more productive workforce and leaner operations. However, brick-and-mortar retail is being disrupted due to the explosive growth from pure e-commerce competitors offering [often] lower prices and a more personalized shopping experience. In addition, the e-commerce sales channel offers deeper product information, community reviews, and greater levels of localization and customization that resonate with consumers.

Brick and mortar retail must adapt to compete in this new environment. A key component of this adaptation is delivering new IT solutions while leveraging the physical assets of the storefront, mixing the benefits of in-store product “touch-and-feel” with the personalization of e-commerce shopping. Merging these two worlds together will create an enhanced shopping experience through the use of mobile Internet devices, often connected through Wi-Fi networks.

This week, we will cover the first of 5 trends driving Wi-Fi growth and new capabilities in retail organizations:

Trend 1: Consumer Interaction and Business Analytics

Physical retailers have the most influence over consumer purchase decisions in the store, when they are standing in front of the product they are weighing whether or not to buy. Historically, this has been through in-aisle marketing and signage. However, customers are increasingly equipped with mobile Internet access and turning to external sources of information in real-time while within a retail store. This has been coined the emergence of the “smart shopper”. These external sources of information are much more comprehensive than what the retailer can provide through traditional in-aisle marketing and signage, and this leaves the physical retailer at a big disadvantage.

Mobile Device Flexibility More Important Than Salary [INFOGRAPHIC]

At Interop New York last month, Cisco’s Sujai Hajela, VP/GM of Wireless Networking Business Unit, said “people are falling in love with their mobile devices,” during his keynote. He was right. People are so in love with their mobile devices that they’ll choose mobile device flexibility over salary.

Consider this. According to the second chapter of the 2011 Cisco Connected World Technology Report, one in three college students and young employees under the age of 30 would prioritize device flexibility and social media freedom over salary in accepting a job offer. In fact, 40 percent of college students and 45 percent of young employees said they would accept a lower-paying job that had more device flexibility and social media access, than a higher-paying job with less flexibility. Wow!

People are so in love and attached to their mobile devices that half of college students and young employees said they would rather lose their wallet or purse than their mobile device, according to the study. And their mobile devices are multiplying – 77 percent of employees have multiple devices and one in three employees globally uses at least three devices for work.

Their attachment to their mobile devices goes a step further. More than half of college students and young employees want to use their own devices to access corporate networks, and two in five consider it a critical function of their job to be able to connect to the network from any location at any time.

So, what does this mean for businesses? People will want to continue their love affair with their mobile devices at work, so it’s better to be prepared to support employee-owned devices as the “bring your own device” trend is only becoming more prevalent.

Securing the Mobile Experience Made Simpler

It is no longer a question of “if” your organization will face the new reality of mobile device proliferation, just an ever closer “how soon.” Users expect the network to enable trends like Bring Your Own Device (BYOD), and they aren’t just using smartphones and tablets to be more productive, they are falling in love with them. For businesses, simply allowing access isn’t the answer. It’s a question of relevant, secure access across the entire network, while protecting corporate assets and delivering an optimal user experience. Cisco focuses on exactly that -- how to enable a simple and secure mobility experience, with a consistent end-to-end architecture across wired, wireless and VPN access.

As a cornerstone of this wired-wireless access architecture, the Cisco Identity Services Engine (ISE) has already been helping customers like Whittier Union High School, San Antonio Water System and BlueWater Communications Group apply consistent security across the entire network through a centralized, single policy source.

Whittier Union High School District, a California high school district serving more than 13,600 students, was facing the challenge of mobile devices. Both faculty and students were bringing their personal devices on campus, many for educational apps and tools.

“It’s becoming increasingly critical to provide employees, students, and visitors access to our network and extensive educational resources given the growing expectations of our tech-savvy population,” stated Karen Yeh, Director of Information Technology, Whittier Union High School District.

Whittier needed a way to apply differentiated policy across their student and staff populations, somehow managing access for both personal and corporate devices, all without increasing IT resources. Karen called Cisco, and two weeks later her team was deploying the Cisco ISE, implementing a single point of security policy for their networks across wired, wireless and VPN. Considering that Richard Nixon, the 37th president of the US went to Whittier High School, the flexible network access enabled by Cisco ISE may be empowering the next generation of leaders, scientist or artists. But, mobile devices aren’t confined to education. San Antonio Water System, a public utility owned by the city of San Antonio, is seeing surprisingly similar issues.

Check your Spectrum!

October 3, 2011 at 10:28 am PST

Lately I had been spending a lot of time in the office rather than on the road.  Which isn’t all bad, as it gives me some semblance of a routine rather than living out of a suitcase.   It has also has given me some spare time to come up with another blog topic, which actually stems from some of the work I have been doing for customers lately.

Typically when a site survey is being done, we will do spectrum analysis work as well, part of my job entails creating and reviewing documents from this work, prior to delivering them to customers, which means I have been watching a lot of  spectrum analysis lately.   Most of the customers I have worked with recently have been with CleanAir APs, so they will be able to monitor their environment in real time, once the WLAN is up and running.  However it’s always a good idea to perform some spectral analysis while you are walking around doing a site survey.  And really why not?  If you are there and you have a few minutes, fire up the old spectrum card and get a capture of whats going on with your RF.   This helps make sure there aren’t any major layer 1 surprises when you go to install the new WLAN.  It doesn’t mean things won’t change, and they often will, due to the dynamic nature of RF.  It’s an ever changing environment, so what wasn’t there on Monday, might show up on Tuesday and be gone again by Wednesday.

Before jumping into particular types of interferes let’s talk about some of the data that Cisco Spectrum Expert can show you.  Two of the things I like to look at when looking at the RF in Cisco Spectrum Expert, are Real Time FFT and Duty Cycle plots, as pictured below.

The Real Time FFT is showing you is the RF energy in real time measured in dBm, so how loud or quiet the device is.  The next is the FFT Duty Cycle, which simply put it’s how utilized the RF is. Let’s say you have a device that is being captured as having a 1% duty cycle.  This means it’s using a very small amount of the available ‘air time’ to transmit its data.  Conversly if there is a device that is showing a 100% duty cycle it is using up all the ‘air time’ and not allowing other devices to use the RF medium to transmit.

Two other views I find helpful are the Spectrogram views.  These display the same info as the plots above, but are plotted out over time.  I use them in a few of the examples below.

A Customer Story: Hospital uses Cisco CleanAir technology to rapidly isolate radio interference in “noisy” environment

We all see a growing trend of using wireless technologies in hospitals due to its benefits in cutting healthcare costs and increasing accessibility for patients and healthcare providers. Wireless applications have the potential to improve care by providing real-time access to a patient’s medical history including treatments, medications, laboratory tests, insurance information and more.

Our customer, Children’s Mercy Hospitals and Clinics – one of the leading children’s hospitals in the U.S.—works tirelessly to help ensure healthcare providers, administrators, and patients have access to leading technologies. So when it came to managing the hospitals’ wireless network, IT managers knew they needed a best-in-class solution.  Deploying the right wireless technologies is not only a matter of adopting reliable solutions – it’s also about putting the systems in place to identify and mitigate wireless interference, which can be a major challenge at a busy hospital.

To combat this, the hospital deployed the Cisco Aironet 3500 Series access points throughout the campus to enable high-performance 802.11n wireless services and Cisco CleanAir technology to both troubleshoot problem areas and optimize the wireless environment. The IT team quickly identified and addressed many areas of interference, including pinpointing that some interference was coming from public buses changing traffic lights at a nearby bus stop.  With the powerful Cisco environment, Children’s Mercy Hospitals is moving to a “self-healing” wireless network that will automatically fix itself when interference is encountered.
