It’s hard to believe that a dusty prairie dog like myself worked in aerospace. How that led to my career in wireless is a story for another time. Did a bunch of stuff on weapons platforms like the B1, ICBM’s for submarines, other interesting things, and then astrophysics platforms for NASA. Huge fun, amazing people, and in general a marvelous experience.
Speed is a critical element in those fields of endeavor. On military platforms it’s often about vmax or maximum velocity; in astrophysics it’s much more about optimal velocity. Too many stories to tell but one of my favorite is when an astrophysicist and myself once stood on the ladder of an F-16 chatting with the pilot who was still in the cockpit. I mentioned that I heard his aircraft could achieve a certain speed. He looked at me, grinned and said, “While I can’t tell you how fast it’ll go, it’s pretty dang quick.” He then put his finger on on the air speed indicator. The number he showed me was much faster than what you read in various publications. It was at that point I realized getting somewhere more quickly than the enemy believes enables you to surprise them.

Often when you mention pillars of salt, people think of the story of Lot’s wife, but there are positive connotations of this expression also. Salt is a staple of life in part because it helps the body turn food into living tissue as well as playing a key role in transmitting nerve pulses. The human body cannot produce salt; it has to come from a source outside the body.
Ubiquity in mobility, like salt, is really quite important. The value of a network is proportional to how well, and how often, end points are connected. The number of end points successfully connected is one metric of a useful network. The number of locations from which a client can connect to other clients is very much a measure of network value. One of the greatest shifts we’ve seen in the mobility market over the last few years is that from islands of connectivity like conference rooms, bullpens and so forth, to truly ubiquitous connectivity. For example, a smart phone allows us to connect effectively from most places we are physically located. I probably set a personal record in 2010 for how many WebEx meetings I had in my car; very cool and for me, highly productive

When it comes to business mobility and collaborating with customers, partners and colleagues, a “good” mobile experience isn’t “good enough.” As mobile workers increasingly adopt dual mode smartphones to remain connected in any environment, the requirement to deliver reliable, business-quality voice and data access across cellular and Wi-Fi networks has become business critical.
Wi-Fi calling is becoming a must-have technology for the enterprise, as corporations seek new ways to reduce costs and improve productivity for employees in the office and traveling overseas. With the joint solution Cisco and T-Mobile announced today, more organizations can meet the mobility and connectivity demands of their employees with the added benefits of improved voice quality, fast roaming and extended battery life. ..one more step towards a true, borderless network experience that connects users securely, reliability and seamlessly anywhere, anytime, on any device.
To address these customer challenges, Cisco and T-Mobile are collaborating to deliver mobile calls over Wi-Fi, enabling reliable, seamless roaming of voice and data traffic between cellular and Wi-Fi networks, allowing businesses to reduce cellular voice calling costs.

We’ve shown you how wireless can break down borders, making your organization more efficient and agile. Today, I wanted to take a moment and share how we’ve been using our own technology to provide world-class medical care to our employees and their families. In this case study, you’ll see how our on-site medical facility, the LifeConnections Health Center, is using the Cisco Unified Wireless Network with our Context-Aware solution to save $140,000/year while improving care.
Founded in 2008, the LifeConnections Health Center began its life with the Cisco Unified Wireless Network and a suite of mobility services, including wireless patient check-in, Cerner electronic medical records and e-prescribing, while temperature monitoring and asset management remained manual processes. “Our nurses had to keep paper logs of our refrigerator temperatures, checking them twice daily to make sure vaccines and lab samples preserved their efficacy,” says David Lees, Cerner clinic manager. “It was also challenging for us to keep track of our medical devices and equipment.”
To solve these issues, LifeConnections leveraged their existing wireless infrastructure to deploy the Cisco Context-Aware Solution with the AeroScout RFID tracking solution. “With this solution, we were able to easily add the temperature monitoring and asset tracking capabilities we needed into our existing Cisco Unified Wireless Network,” says Uma Desiraju, IT manager. “Leveraging our wireless infrastructure for these new services is enabling us to achieve a nine-month ROI.”

I heard a pretty good story recently from one of my favorite people in the WLAN industry, a very sharp guy who recently changed employers. As I’ve not procured approval to use his name, we’ll forego that for now, but it’s a great story nonetheless and is an example of the power of social networking in the professional environment.
The scenario takes place aboard a modern cruise ship on which my colleague and another person in question has installed a vast wireless LAN; a total of 1,000 access points will be in operation by the time you read this, which places it among the very largest of WLAN’s on the planet. Ships, airplanes and cars commonly feature numerous types of wireless connectivity, including AM, FM, satellite radio, GPS, Bluetooth, mobile cellular, and more. Amazing.
The challenge in this story was that deep into the mobility deployment install effort, they ran into a major code snag. Fairly common if you’ve done these, in particular as the deployment moves toward two critical phases, incorporation of clients and layering on the security elements.
After lighting up the WLAN for the first time, they discovered the code in the controllers simply wouldn’t perform the functions they needed. Hundreds of miles from shore, and deep inside the bowels of the ship, they were in a bit of a jam. My colleague who is probably the best social networking person I know, sent out a tweet asking if any other engineer had encountered his problem and how did they resolve it. The result was quite interesting; within seconds, dozens of engineers from around the world had sent tweets in response. A number of them included url’s with an optimal code solution located.
