Increasing Mobile Network Efficiency with Voice over Wi-Fi (VoWi-Fi)

Have you ever walked into the office or perhaps an area in your home with your mobile phone and tried to make a call, only to have poor LTE/4G/3G signal strength keep your call from connecting? What did you do? Well if you’re like me, you probably wanted to throw your phone and revert back to the reliable, old land line. What if, instead of relying on the signal strength of your mobile service provider, you were to make voice calls over your home or office Wi-Fi network?

How the Intercloud Empowers Mobility Intelligence for Service Providers

When I talk to service providers around the world, many of them tell me how difficult it is to capture intelligent information about their customers’ mobile usage, including whom their top customers are, which social media sites are being accessed, and what information is being streamed live. What’s more, mobile data and usage continues to grow exponentially which will make capturing this information even more difficult over time. According to the most recent Cisco® Visual Networking Index (VNI) Global Mobile Data Traffic Forecast by 2019, there will be over 21 billion mobile connections. In addition, mobile data traffic will grow at a compound annual growth rate (CAGR) of 57 percent, reaching 24.3 exabytes per month by 2019.

Now, mobile service providers need to better manage all Read More »

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 »
