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 1

In 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 »

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.

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.
University of California, Santa Barbara’s first annual beachside hackathon was held from January 30 to February 1 and hosted over 500 participants. The students came from all over California to both show and tell Read More »

Voice over Wi-Fi
With its native support in Apple’s iOS 8.0, Voice over Wi-Fi (aka Wi-Fi Calling) has suddenly gotten a lot of attention. With Voice over Wi-Fi, a mobile phone which used to be only limited to placing and receiving calls and texting when “cellular coverage” was present, can now use Wi-Fi to provide the same service!
Voice over Wi-Fi Benefits Everybody
Mobile Network Operator (MNO) can not only “offload” their data traffic to Wi-Fi networks but now can do the same with the voice traffic. Voice over WI-Fi allows them to also extend their services further and at much lower cost than Read More »
