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?

Converged Access Improves Wireless Performance at South Island School, Hong Kong

South Island School in Hong Kong is made up south island school 2of students from around the world, with 1,400 students from over 35 countries. One value that sets the school apart is its commitment to using technology in the classroom. For instance, every student has a laptop that they use to access e-books, watch educational videos, and complete homework assignments. Some exams are even taken digitally.

With wireless devices used daily by every student and faculty member, a stable network connection is almost as important as pencil and paper in classrooms. South Island School’s existing Cisco network had reached end of life, and the school needed to refresh the infrastructure with a network that could meet bandwidth needs for years to come.

“We looked at other vendors, but we were extremely impressed with how the existing Cisco equipment performed over the years,” says Victor Alamo, ICT manager at South Island Schools. “By upgrading to the latest Cisco access points and switches, we’d have an infrastructure that would keep up with our needs.” Read More »

A Wider View of Collaboration – and its Benefits

“Collaboration” usually means “people working together productively by sharing voice, video, and data”. Inside Cisco, the standard idea of Collaboration includes a lot of IT Technology, like:

  • all voice-based Unified Communication (that is, all IP Telephony from hardware and software phones, and all Unity voicemail, and all Contact Centers)
  • all Video conferencing (from Jabber or WebEx clients, video phones, desktop video, room TP, and immersive TP),
  • all streaming video like Cisco TV (IP/TV) for large multicast events, and
  • software clients like email, web sites and blog sites and document repository sites, Jabber IM, voice and video, and WebEx voice, video and data

But sometimes Collaboration means more. For example, Cisco IT likes to say that we “enable people to collaborate with any device, from anywhere, at any time” which really expands the scope of collaboration. Read More »

Observations from Mobile World Congress 2015

I have just returned from a very interesting and jammed-packed week at Mobile World Congress 2015 in Barcelona. A record 93,000 plus people are estimated to have attended this year’s premier technology festival. Much has changed in the industry over the last year since I reported my observations of MWC 2014. However, what is most remarkable is how the boundaries of mobility continue to expand and morph – everything now seems to be mobile? As such, the show offers a fascinating glimpse into the future of technology and the major social and business shifts that we can expect in the next few years.

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 »
