Voice Calls from Any Mobile Device – It’s Happening Now

Like most kids, my children love to call their grandparents and tell them about what is happening at school. We are lucky that we have a great home POTS voice service through our local telephone company. My kids are growing up quickly, and I anticipate that they will want to eventually call from whatever device is in their hands. That could be my cell phone or the regular ‘land line’ home phone. Or what if my son wants to use my Kindle or an iPod touch to make the call? These devices are typically not used for voice calls, only for data applications.   Many of them only have Wi-Fi, and right now cannot make voice over Wi-Fi calls without a number of new developments on the device.

The great news is that there are many developments in the Voice over Wi-Fi (VoWi-Fi) space to get us closer to that vision. Some of those new developments are being shown this week at Mobile World Congress. Read More »

Introduction to 802.11ac Wave 2

802.11ac is the hottest topic of discussion and deployment in WiFi over the past couple of years. Ratified as a standard by the IEEE in November 2013, the first phase of 802.11ac products brought to market is commonly referred to as Wave 1, and provides roughly a 3x improvement in network performance over its predecessor 802.11n: 1.3 Gbps compared to 450 Mbps in 5 GHz respectively when utilizing the maximum channel width and modulation supported .

Next up 11ac Wave 2, the next phase in 802.11ac, will begin entering the market later in 2015 in the form of both new client devices (smartphones, tablets, laptops) and new Access Points and modules, providing two significant enhancements building on Wave 1802.11ac image1

Ready for Mobile World Congress (MWC) 2015!

Brian's GarageIn just a couple of days, many of you will be taking planes, trains, and automobiles to sunny Barcelona. I see that the weather forecast is for 65ºF / 19ºC for the opening day of Mobile World Congress. I really appreciate how the MWC timeframe has gradually crept closer to Spring over these past few years. Maybe you are not paying attention to the weather as much as me. You would if you had the same view that I have out my window, where it is currently 20ºF / -6ºC. Yes, I should clean off my roof. But I do like that my garage roof serves as an historical record of the unmerciful winter we have had here in Boston in northeast U.S., where we have had over 100 inches / 250 cm of snow so far.

So my main point is, if you don’t go to MWC 2015 next week, you are going to miss Read More »

The Mobile Paradox – Why Are There Price Wars in a Time of Plenty?

One of the first lessons that every economics student is taught is “supply and demand” – the fundamental economic principle that price goes up with increased demand. Yet we are witnessing the opposite to these age old principles in the mobile business. Despite phenomenal demand for mobility services, the mobile operators that provide these services are engaged in a fierce price war.

Sun, Sand, and APIs: Cisco CMX (Connected Mobile Experiences) in Action at the 1st Annual UCSB Beachside Hackathon

I’ve always enjoyed my work in coding. Sure, some days it can be monotonous, frustrating, and terrible on my back and eyes, but more often than not I find myself elated to be able to intricately manipulate letters, numbers, symbols, and lines to form a beautiful new creation. Being able to see that same elation within the eyes of so many young and eager minds this past weekend, reminded me (once again) of what incredible opportunities we have to further technology and better our world.
