Engaging customers via their mobile devices is an exciting proposition for many organizations; however, it has to be done with care. These solutions often carry a significant cost and depend on a Return on Investment (ROI) model to make sense.
Achieving this ROI requires walking a fine line between meaningful engagement and being a nuisance. Here are five best practices to help you do that.
5 ways to ensure your mobile strategy works
1. Think big picture
The goal is to create a user experience that provides vast amounts of data to the organization while delivering value to the customer. Accomplishing that means the experience needs to be immersive and omni-channel (e.g., SMS, email, app-based, digital signage, direct mail, etc.).
Too many organizations jump straight to the mobile application without realizing adoption of mobile applications is low and retention of those mobile apps is even lower. A holistic approach that embraces the web (traditional and mobile), mobile apps, digital and physical signage, and some of the emerging areas such as augmented reality (AR) and context-aware chatbots will be far more successful.
Analytics and business intelligence tools must be included because understanding the success of these messages and their impact on the bottom line is a necessity, as engagement attempts that are ill-received may create a negative effect on the business.
2. Establish a baseline
Before rolling out any new engagement solution or even a single targeted campaign, it is important to understand the baseline. What is normal for a specific time of day, day of week, demographic, location, etc.
If there are areas in which these baselines are unknown, the success of an engagement will also likely be unknown. The length of time to determine a credible baseline depends on business and vertical; however, a month of data will provide statistically valuable data for many organizations.
3. Consider your social credibility
Each engagement or touchpoint with the user must be carefully weighed prior to being implemented, as the organization is spending “social credibility" with the customer in issuing these engagements. Determining that a message is hitting the right person at the right time and place is paramount to success.
While the organization may want to drive a specific behavior, it must be done in such a way that it is graciously accepted by the recipient. For less important messages, consider other channels for delivery—email, direct mail and digital signage integrations are options that are less invasive than a targeted push message.
4. Leverage employee engagement
Business should ensure the human component isn’t lost in this digital marketing frenzy.
Consider a scenario in which an employee could be notified when a user has spent more than five minutes in front of a specific retail display or there has been a high density of users in line for a drink at a sports game or concert venue. Rather than trying to ping users to have them go find another bar, consider triggers that have an employee come over with a mobile payment system and perform line-breaking transactions. This human component may still be considered a “digital engagement," but it won’t feel like it to the consumer.
5. Keep it fresh
Digital engagements should always be timely and relevant. Organizations can’t afford to be lazy about managing these platforms because pushing irrelevant messages will drive away customers, cause them to remove their mobile apps, and even consider competitors.
Campaigns should also create a sense of urgency—create a fear of missing out or at least ensure customers understand this immediate deal is good for only the first 100 redemptions.
Gamification is one way to keep things interesting for consumers, and it can drive additional spend as it may promise “bonus" rewards for the additional engagement. The solutions should be simple enough that they can be managed by marketing teams and not IT.

Heading into Aruba Atmosphere this year I was most excited to see Aruba’s new Niara solution in action and learn more about this product as it solves a very real need in every network. Inherently any network policy grants some sort of access to the network and users are free to work within the confines of that policy. Even using 802.1X-based authentication and dynamically provisioned VLANs, access roles, downloadable ACLs, etc. isn’t necessarily enough. Niara solves for these issues in an appealing way and lessens the workloads for SecOps teams.
Case #1: Stolen Credentials
A known valid user can operate within their policy, but what happens if they are compromised either through social engineering, weak passwords, poor password management, etc.? Niara builds a profile of what is typical behavior of a specific user, if their patterns change this will be identified by the system. Perhaps the user starts attempting to access new areas or is visiting new websites—by a change in behavior, it is possible to identify a need for a change in policy, alert the SecOps team, or eventually automate remediation or lockdown of the user. Comparing to a baseline as well as other similar users gives Niara a frame of reference for the user under evaluation.
Case #2: Malware and Viruses
Both malware and viruses are capable of changing the behavior of network attached clients, while numerous tools already exist to help combat these Niara could serve as a welcome tool to identify and isolate infected clients or in a perfect world learn about how a Day Zero Attack might attempt to compromise the network and automatically harden the network in anticipation of this attack. The combination of these capabilities along with Aruba’s open APIs using Aruba’s Exchange offers some very interesting possibilities by enabling the collection of data from ecosystem partners with a greater speciality in the malware and virus arena. Imagine a world in which your firewall vendor has detected a new type of malware, shares that data with Aruba ClearPass and Niara via APIs, syslog, SIEM, or other similar routes and then the network automatically reacts to prevent the spread of that malware at the same time you are being notified.
Case #3: Software Bugs/Anomalous Behavior
If an application is updated and begins to operate differently on the network, Niara can identify this and enable teams to understand the new behavior. New behaviors deemed as risky can be mitigated against and feedback can be provided to the company’s development team. A specific example of this was provided at the conference in a popular file share company who’s update generated unwanted traffic on the network. Niara’s machine learning was able to identify and allow this undesirable behavior to be stopped.
Aruba, a Hewlett Packard Enterprise Company opens the door to a world of possibilities with the addition of machine learning and extends those capabilities elegantly through their open architecture in Aruba Exchange. I would anticipate that this field of machine learning is going to explode in the networking world as IT teams are facing increasingly difficult security challenges and are being asked to do more with less people and less resources. Automation of detection and defense should be able to solve 75-80% of the issues out there, enabling IT to focus on the most challenging and highest value problems out there.
Aruba, a Hewlett-Packard Enterprise company, unveiled their new Mobile First Platform last week and I had a front row seat as one of the Mobility Field Day Live delegates. Aruba’s announcement was made a day prior to our session, so it was pretty exciting to discuss such a fresh topic. The foundation that Aruba is creating here is impressive and the implications are tremendous, especially if we look at extrapolating this in the near future.
Aruba announced the release of AOS version 8.0, which marks the first major overhaul of the code in quite some time. This release is at the center of Aruba’s Mobile First Platform and is designed to handle the next ten years of wireless, which is quite an ambitious goal as the near future has 802.11ax (aka Ten Gigabit Wi-Fi). Aruba highlighted that the intelligent layer of services required to run networks today is reaching its limits on controllers, so they have created a new alternative in the form of a Mobility Master that can run these intelligent services on behalf of the controller hardware. The Aruba Mobility Master has been virtualized so that it can run on an x86 virtual machine in VMWare (KVM coming soon with version 8.0.1). This new role replaces the now legacy Master Controller so most environments will benefit from a reduced amount of hardware on-site and can leverage investments already made for the new architecture where desired. Also of interest for most is that there is zero cost for these virtual machines, the only thing that matters is the number of access points are being managed. The primary tradeoff between a controller-based and virtualized infrastructure today is throughput as the VM-based controllers do not have hardware encryption modules and as a result they cap out around 4-5 Gbps.
Aruba has also introduced a new UI with AOS 8.0, which is a welcome feature as it had been fairly complicated for a new user. The new UI brings some much needed features such as simplified profiles, tab completion for profile names in the CLI, multithreading in the CLI, etc.
In-Service Upgrades are also new with the advent of AOS 8.0 and the Mobility Master. The increased compute and storage allow for services that now reside on the Mobility Master to be upgraded and impact the environment immediately without requiring an upgrade to access points or controller infrastructure.
Watch more on AOS8 via the Tech Field Day YouTube Channel.
Zero Touch Provisioning
Included in the move to a Mobility Master, is Aruba Zero Touch Provisioning which allows the Mobility Master to handle all configuration for controllers throughout the environment. Additionally, the previous requirement for the Mobility Controller and Access Controllers to be running the same version of code has been removed. The Mobility Master must run the latest code supported in the environment, but will be backwards compatible with older versions of code running on the controllers. This feature will greatly benefit risk adverse customers to quickly take advantage of the new features in administrative buildings, but maybe roll out slowly to a hospital or manufacturing site.
The Multizone architecture allows for SSIDs to terminate to multiple controllers, creating an end-to-end encrypted session from client to controller when in tunneled mode. Terminating SSIDs on different controllers extends beyond the data flow and into how the AP is managed. Controller 1, as the primary, gets to set all of the AP settings (IP address, dhcp, etc..). Controller 2 gets to set only the settings for SSID 2. An admin of controller 2 cannot see any of the info for controller 1 including SSIDs, security types, auth servers, users, etc.
Aruba AOS8 brings controller clustering to the table. All elements in the cluster must be running the same code and be part of the same family (e.g. All 72XXs running 8.0 code). State information is maintained for clients and access points with a designated backup controller within the cluster. The clusters also participate in user load balancing. Primary and Backup controller per user is maintained in the cluster and will be shared with AirWave later in the year. This is useful across all customer types, but especially those with very large campuses (e.g. higher education or Fortune 500 headquarters, etc.). Clusters scale to 12 controllers with 72XX series and 4 with 70XX controllers.
Aruba Clarity allows the access points to associate to another access point and run synthetic tests from the “client AP" to the Clarity server, effectively building a baseline and providing tremendous visibility especially for remote sites. Clarity Live tracks DHCP and DNS requests and responses in real-time to profile the typical health of the network. Clarity Synthetic allows for RF performance testing, iPerf, web page loads to a URL (Salesforce, etc.) Upcoming features that were hinted at but not confirmed include scheduling and wired line monitoring and testing.
Another feature of AOS8 is Aruba’s new AirMatch feature that enables better channel reuse. This feature is important as legacy radio management was designed for a previous era of wireless networks. In today’s high capacity world that needs to support users and things the old way of doing things is not good enough. AirMatch looks at the system as a whole to maximize channel reuse and capacity on a daily basis and determines based on a day of usage what the best wireless combination of radios include. Advanced users will be able to tune AirMatch functionality to meet their needs from the command line, but this will be obscured from the GUI to protect users from causing harm.
The Mobility Master will have the context aware APIs that exist with Aruba’s Location Engine (ALE) to enable integrations with other systems via REST or published to other resources using a ZeroMQ to move that data to a database. Configuration APIs have also been enabled to allow APIs configure the network, SSIDs, etc.
Enhancements have been added that enable categorization of applications and grouping of applications. For instance, a group called “Students" or “Nurses" could be created simplifying management. Custom applications are now supported and AppRF definitions are now treated like antivirus updates and can be updated without impact to the network.
In all I was impressed with what was announced for this release. Our delegate panel kept asking for more, but when you look at what has been accomplished, our requests were in line with what you’d expect this roadmap to look like as it unfolds. The shift to an API driven infrastructure is exactly where the world needs to be heading and abstracting software from hardware is inline with every other major shift in the industry. I am looking forward to the APs themselves running microservices in the future that can be upgraded, restarted, etc. with no impact to end users—it seems to be an inevitability at this point. This Mobile First Platform is well thought out and perfectly aligned with the automated and intelligent future that we are all looking for as it allows us to focus on the core business and offers much needed agility.
The WLAN Pros Conference is truly a unique experience that I look forward to all year long. Throughout the year we are inundated with vendor marketing material and embroiled in competition. WLPC is a few days where we can come together as individuals, educate each other, build the community and challenge each other to be better at our craft. This year’s conference will be in sunny Phoenix, AZ. Read more about it here. If you’ve never been before and you have an interest in Wi-Fi I urge you to make plans to attend. It is a great opportunity to network and learn from others in the field.
This environment provides a great opportunity to get up and speak about something you are passionate about. The mix of longer presentations and ten talks allow for a lot of variety and depth of topics. This year I’ve selected a topic on Healthcare wireless as my main presentation topic and then will use a Ten Talk slot to provide a sneak peak into my Bluetooth World presentation that I will be giving in March at Levi’s Stadium.
In case you missed it, Aruba Networks, an HP Enterprise Company announced the availability of their new Aruba Sensor product this week. This was spoken about at Atmosphere back in March, but then had seemingly disappeared. This new sensor enables Aruba Network's Meridian cloud analytics and wayfinding solution and best in class beacon management capabilities to be used on any wireless network. These sensors have a Low-Energy Bluetooth (BLE) radio to act as a beacon and manage other beacons in within a 25 meter radius and a wireless radio to provide network connectivity. Power is delivered through either AC power or USB and both power options offer security locks to ensure the safety of the Sensor. Making the same solution available for any wireless network is a huge deal as it allows for standardization of an engagement solution. ClearPass, Meridian and the Aruba Sensor/Beacon offer tremendous capabilities for any organization's network. Kudos to the team for embracing the market as a whole!
I've had the opportunity over the past couple of years to work with a large customer of mine on a refresh of their entire infrastructure. Network management tools were one of the last pieces to be addressed as emphasis had been on legacy hardware first and the direction for management tools had not been established. This mini-series will highlight this company's journey and the problems solved, insights gained, as well as unresolved issues that still need addressing in the future. Hopefully this help other companies or individuals going through the process. Topics will include discovery around types of tools, how they are being used, who uses them and for what purpose, their fit within the organization, and lastly what more they leave to be desired.
Blog SeriesOne Company's Journey Out of Darkness, Part V: Seeing the Light Also on Thwack!
Throughout this series I've been advocating the formation of a tools team, whether it is a formalized group of people or just another hat that some of the IT team wears. This team's task is to maximize the impact of the tools that they've chosen to invest in. In order to maximize this impact, understanding who is using each tool is a critical component of success. One of the most expensive tools that organizations invest in is their main network monitoring system. This expense may be in the CapEx spent obtaining the tool or the sweat equity put in by someone building out an open source offering, but either way these dashboards require significant effort to put in place and demand effective use by the IT organization. Most of IT can benefit from these tools in one way or another, so having Role Based Access Controls to these platforms is important so that this access may be granted in a secure way. Screens should be highly visible so that everyone in the office can see them.
Network Performance Monitoring
NPM aspects of a network management tool should be accessible by most if not all teams, although some may never opt to actually use it. Outside of the typical network team, the server team should be aware of typical throughput, interface utilization, error rates, etc. such that the team can be proactive in remediation of issues. Examples where this has come in useful include troubleshooting backup related WAN congestion issues and usage spikes around anti-virus updates in a large network. In both of these cases, the server team was able to provide some insights into configuration of the applications and options to help remedy the issue in unison with the network management team. Specific roles benefiting from this access include: Server Admins, Security Admins, WAN Admin, Desktop Support
Deep Packet Inspection/Quality of Experience Monitoring
One of the newer additions to NMS systems over the years has been DPI and its use in shedding some light on the QoE for end users. Visibility into application response time can benefit the server team and help them be proactive in managing compute loads or improving on capacity. Traps based on QoE variances can help teams responsible for specific servers or applications provide better service to business units. Specific roles benefiting from this access include: Server Admins, Security Admins, Desktop or Mobile Support
Wireless Network Monitoring
Wireless has outpaced the wired access layer as the primary means of network connectivity. Multiple teams benefit from monitoring the air space ranging from security to help desk and mobile support teams. In organizations supporting large guest networks - health care, universities, hotels, etc. the performance of your wireless network is critical to the public perception of brand. Wireless networks monitoring now even appeals to customer service or marketing teams. This addition to non-IT teams can improve overall communications and satisfaction with the solutions. For teams with wireless voice handsets, telecom will benefit from access to wireless monitoring. In health care, there is a trend to develop a mobile team as these devices are critical to the quality of care. These mobile teams should be considered advanced users of wireless monitoring.
IP Address Management (IPAM)
IPAM is an amazing tool in organizations that have grown organically over the years. Using my customer as a reference, they had numerous /16 networks in use around the world, however many of these were disjointed. This disjointed IP addressing strategy leads to challenge from an IP planning standpoint, especially for any new office, subnet, DMZ, etc. I'd advocate read only access for help desk and mobile support teams and expanded access for server and network teams. Awareness of an IPAM solution can reduce outages due to human error and provides a great visual reference as to the state of organization (or lack there of) when it comes to a company's addressing scheme.
I personally do not advocate an environment that promotes read-only access for anyone interested in these tools as the information held within these tools should be secure as they would provide the seeds for a well planned attack if so desired. Each individual given access to these tools should be made aware that they are a job aide and carry a burden of responsibility. Also, I've worked with some organizations looking for very complex RBAC for their management teams, unless you have an extremely good reason, I'd shy away from this as well as the added complexity generally offers very little.
Wireless Field Day wrapped up last week with an incredible visit to Levi's Stadium, home of my San Francisco 49ers. As both a rabid football and Wi-Fi fan, it doesn't get any better than this to culminate an already awesome week. Aruba Networks and Levi's Stadium have set a new bar in terms of connectivity, engagement with the fan base and building for the mobile generation. Mobile Engagement at the stadium is done leveraging a custom app that has been location enabled using Aruba's Meridian SDK and a hybrid Wi-Fi and low energy bluetooth (BLE) infrastructure. If you aren't familiar with beacons and low energy bluetooth, please refer to my previous posts on the subject as they will serve as a good primer.
Managing and Deploying a Beacon Infrastructure
We've all seen a lot of hype around what BLE can do for you, but little has been mentioned about some of the challenges around managing these infrastructures. I had an opportunity to spend some time with Aruba Meridian back in January of this year and go through a class in which we built an underlying beacon infrastructure configuration and then developed an app that used that infrastructure. This process involved using the Aruba Beacons app and individually configuring each beacon. This process applies for firmware upgrades and reprogramming the beacons as well, even after deployment unless some other system is in place. Inherently beacons require that you are within their proximity 30-50' typically to do this kind of work. Needless to say in an environment like Levi's Stadium this would be unmanageable.
The Aruba Advantage
Aruba's infrastructure enables the management of beacons via bluetooth radios resident on their new access points or retrofit on the previous generation of APs via a USB bluetooth beacon. Aruba entered the hardware world of beacons to do right by their customers in developing an end-to-end solution that is supportable. This configuration enables beacon configuration and firmware updates to be executed via the Meridian cloud and pushed down to the beacons via controllers/instant APs and over the bluetooth radios to the beacons themselves.
I have been a fan of Meridian Apps from the beginning and commend Aruba for pulling the trigger and acquiring the company. The "better together" mantra definitely rings true here as Meridian simplifies the most difficult piece of engaging customers--the mobile app. If you've never explored this world, it is a confusing mix of custom app developers, SDKs, etc. each with their own pros and cons. Meridian offers two levels of integration, one is the Meridian app maker and the second is the their SDK.
AppMaker and Navigation
The AppMaker simplifies the app creation process so much that most organizations could do this themselves if desired. I do recommend some guidance around the structure and design of the app, but it is built so that a marketing person could actually construct the app. My first go at building an app that included some points of interest, wayfinding, etc. took a couple of hours for something that would pass as an enterprise-grade mobile app. I've made multiple comments on social media about the wayfinding capabilities, especially the Americans with Disabilities Act (ADA) routing. The mobile app creator simply draws in the "roads" and the Meridian engine handles the routing. For each of these roads there is a flag as to whether or not that road is ADA accessible, enabling a user to request accessible routing if desired.
"Google Maps, but Indoors" is one of the phrases heard most when it comes to describing what wayfinding is to the layperson. Aruba's BluDot solution gives you that real-time blue dot experience that shows you your current position. This makes finding directions easier as there is no need to enter a source and a destination, you simply need to know where you want to go. BluDot is powered by a combination of beacons and the Meridian cloud service and is the best in the business at doing this. The maps use a scalar vector floor plan to ensure navigation and zooming in/out look great and enable the app creator to create points of interest throughout the map.

Campaigns are the traditional push messaging of the beaconing world and allow for interaction with end users. Campaigns can be configured to run once, on a set schedule, or for a particular zone. Again Aruba does a brilliant job in making this easy to implement and understand. These push messages can make your visitors aware of a guest network, offer incentives, make them aware of current promotions, etc.

I've been watching the content published on Wireless Field Day ever since I had first heard about it late in 2011. The presenters have to be on point given their demanding immediate audience and the results are fantastic. The team is interested in real world performance rather than marketing spin. Going under the hood and digging into the inner workings of the technologies in a public setting is such a great way to build confidence in a product and it enables me to better set expectations for my customers when I am out educating them on the market. I recently went to the site to check out the upcoming event and found that there was interest in finding new delegates for Wireless Field Day, so I reached out and am so glad that I did. After a few discussions, I was officially offered a delegate spot for Wireless Field Day 8 and couldn't be more thrilled about it.
For me, this is where the work begins. I am honored to be part of this group, but also feel challenged to step up and contribute like some of others in our great community do. Thank you WFD, I am excited and humbled by the offer and look to make this the best WFD yet.
Tune in Oct 30-Sept 2 at the site below.
