It has been 15 years since Kevin Ashton popularized the term the Internet of Things. How could we have known then what that would come to mean and the huge impact that it would have on our lives? Cisco projects that 50 Billion things (or devices) will be connected to the Internet by 2020; or, the equivalent of 6 devices for every person on the planet. This exponential growth of connected devices is fundamentally impacting both society and the economy—changing our lives forever.
However, with all of our focus and media attention on the Internet of Things, we are really missing the fundamental technology revolutions that are reshaping our world. Radical advances in processing, storage, wireless technologies and new ways of delivering technology are reshaping our world – all at a much faster speed and drastically reduced price.
In my view, the Internet of Things is really a short-hand for the five technology pillars that are shaping a revolutionary new, connected world. Read More »

Hong Kong Academy (HKA) is an International Baccalaureate school with students ranging from pre-school to grade 12. They are a relatively small school in terms of total employees and students. Their goal is to offer a personal and individualized form of learning.
HKA identified that the best way to achieve their goals was to encourage the use of technology to create a community amongst teachers and students. They recently constructed a new building and had the opportunity to build a network to meet their current and future requirements.

Last week, the official launch of the Wi-Fi CERTIFIED Passpoint™ Release 2 interoperability program from Wi-Fi Alliance (WFA) revealed the next chapter in enabling mobile client devices to easily connect to a secure (i.e., strong encryption and authentication) Wi-Fi network. And once again, Cisco is at the forefront of furthering the proliferation of new and improved Wi-Fi capabilities by having participated in and contributed to the successful launch of Passpoint Release 2.

Ever since the much anticipated 802.11ac standard was ratified and supported by Enterprise class access points (AP), I’ve asked myself the question that perhaps other network and Radio-Frequency (RF) engineers have: how much of the theoretical 1.3Gbps 802.11ac data-rate can I really deliver to my users and what is the overall throughput experience when I deploy at scale or in high-density (HD) scenario? On the surface, it may seem intuitive that I should allocate 80MHz to my 802.11ac radios to achieve the best throughput BUT as it turns out, this approach has limited scale and may lead to less total throughput than a smaller 40Mhz channel – so in this case; less may be more!
This is due to the fact that while in a single-cell (AP) scenario (say 5000 sq. ft) it is realistic to expect most capable devices can reach 1.3Gbps (1Mbps of throughput) with 3 spatial stream (SS) & 80MHz (e.g. MacBook Pro) and 433Mbps (300Mb/s of throughput) with 1 SS & 80MHz (e.g. iPhone 6) BUT this throughput degrades quickly in a multi-cell environment where co-channel-interference (CCI) from neighboring APs can dominate. So we need to look at the primary CCI contributors, which are: Read More »

Rijksmuseum in the Netherlands is one of the top 10 art and history museums in the world.
We live in an era where information is available in the palm of our hands and traditional institutions such as museums are inevitably facing the consequences of this. Even though the museum dates back to the 1800’s with artifacts from the middle ages, they have embraced modern technology to adapt to the changing landscape. This was as a matter of survival considering the competition from other institutions.
