Indoor Wi-Fi Location and Beacons: Better Together Part 2

wifibeaconLocation-based services have been getting a lot of attention lately and people are increasingly curious about how Wi-Fi and beacons play together in the hot space that is indoor location technology. In my last blog I reviewed how beacons work and how to differentiate when to use Wi-Fi and beacons. There’ve been some great questions about beacon technology and how it complements Cisco’s location-based Connected Mobile Experiences (CMX) solution, so I want to follow up on these topics with everyone.

What types of beacons are there?

Generally, there are two different classes of beacons: transmit only and backhaul enabled.

Transmit only beacons are exactly as they sound -- they simply transmit information to anyone that is capable of hearing (bluetooth enabled smartphones). They do not receive or pass any data or information upstream.

Apple’s iBeacon is the best example of this type of BLE beacon. You can think of them like the navigational beacons used by airplanes when on approach to major airports. The beacon doesn’t even know the plane is there, but the plane is aware of the beacon and knows where the beacon is allowing it to take the correct action. Same is true for smartphones and transmit only beacons like iBeacon -- the intelligence is located in the mobile application which must recognize the beacon and take appropriate action.

Backhaul enabled beacons generally include a Wi-Fi chipset for either management or data capabilities. Some backhaul enabled beacons are USB enabled and take advantage of whatever connectivity exists within the PC they are connected. Read More »

Love Wi-Fi? Tune in for #WFD7 this Friday

Tomorrow’s a special #WirelessWednesday, hats off to the folks working hard at Tech Field Day for kicking off the SEVENTH installment of Wireless Field Day. It’s an exciting time  for the industry to give the delegates and the world wide web of Wi-Fi enthusiasts a glimpse behind the scenes of some of the latest technologies, and we are ready to put on a show.

This year, Cisco will host Wireless Field Day 7 delegates at the Cisco Meraki San Francisco office this Friday.

We will be spending 2 hours discussing the forefront of Wireless technology with Cisco thought leaders. Here is a sneak peek of what will be covered.

  • Latest updates on the Cisco Meraki MR product line.
  • Deep dive into the Cisco Meraki traffic analytics algorithm; how it works and how it scales for large deployments.
  • Deep dives into MU-MIMO and RX-SOP; what they are and how they work
  • Discussion on 802.11ac and where it’s going.

The show will start at 9:30am PST. We’ll be on Twitter with #WFD7 and streamed live on the TechFieldDay website. Tune in Friday to hear updates on the future of wireless networking.

Behind the Network @ Mobile World Congress 2014: Hotspot 2.0

Mobile World Congress (MWC) 2014 was the largest mobile industry exhibition in the world, where over 1800 companies showcased and launched their latest products and services. This event was visited by over 85,000 attendees from over 200 countries around the world, to learn, network, inspire and innovate. Providing them seamless and robust data network was the first priority. GSMA , Fira de Gran Via and Cisco took this challenge to provide them next generation Wi-Fi experience with seamless connectivity and onboarding using Hotspot 2.0 service on the top of baseline free Wi-Fi service.

Hassle and risk are the two key factors involved in connecting free public Wi-Fi. When you are traveling in the different countries, you get off the plane and turn on your cell phone… and within few seconds you get connected to the cellular network. There is no need to search for a suitable network manually (hoping it’s not rigged by a hacker), then enter long password or credit card details to pay for the service. But unfortunately connecting to Wi-Fi is not that simple. Hotspot 2.0 Service addresses these problems by automatic network discovery and selection, seamless network access and secured authentication for the Passpoint certified devices.

The Key to Success in Tracking Mobile Devices: Symbiosis, Not Espionage

As a shopper enters a store, the retailer uses Wi-Fi to track her movements, interests, and shopping habits, providing a treasure trove of insight valuable to merchandising and product development alike.

And as advances in Wi-Fi promise increasing location precision and beacons promise pinpoint location based services, the future appears to be smooth sailing, right?

Well, not exactly.

Tracking the position of mobile devices accurately and correlating to personal data has been one of the most sought after Big Data objectives. And not just for retailers — the potential wealth of business value from data has drawn piqued interest across nearly all industries.

Yet in the real world, issues arise from both technology challenges and privacy concerns alike.

Technology challenges include:

  • Typical Wi-Fi accuracies in the 7-to-10 meter range (though Angle of Arrival and improved location analytics promise dramatic improvements)
  • Infrequent mobile device probing to conserve battery power
  • Interference from metal shelves & fixtures, water in products (and people!)

Privacy qualms speak to the heart of transformation in the Internet of Everything (IoE) age. IoE, after all, is the explosion of network connections among people, process, data, and things — and promises to be one of the most impactful periods of change in our history. And the people element is in some ways the whole point — to make our lives better, healthier, more efficient, and so forth. But the people issues will be just as challenging as those that arise around technology. Read More »

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.
