With any new technology comes a new set of obstacles to overcome. 802.11ac is no exception. Last week we talked about CleanAir for 802.11ac and why spectrum intelligence still matters. Another challenge is scalability. In this post I will give you some details on new HDX feature, Turbo Performance, which allows the AP 3700 overcome common scaling issues to scale amazingly well.
What’s Different with 802.11ac?
802.11ac means higher data rates, which means more packets per second (PPS). There are three reasons for more PPS with 11ac: wider channels, increased modulation and increased aggregation. Channel width doubled to 80 MHz, modulation increased from 64 QAM to 256 QAM, and aggregation increased from 64k to 1MB!
With 802.11n, an AP might have had to push 30,000 1500 byte packets per second through the APs data plane. Today with 802.11ac that could now be 75,000+ PPS. More PPS means more load on the APs CPU, so to really keep up with the demands of 802.11ac, we needed to go back to the drawing board. Read More »

Superheroes and their super strengths have long captured our imaginations. Today, such daydreams – and abilities are getting just a bit closer to reality.
When your smartphone meets the Internet of Everything (IoE), it will make some common activities, such as shopping, a bit more super. Mobility has already assumed a central role in the retail experience, but how are increased contextual capabilities emerging across the entire customer journey?
This blog discusses how some retailers are connecting people to people and people to things, while tapping superpower abilities and making their brands and product experiences distinct.
With the superpowers of smartphones and IoE, retailers can insert themselves into crucial conversations with the customer by offering price matching, access to expanded inventories, suggestions, and shopping lists. All of these combine to keep shoppers engaged and moving along the journey – and beyond.

This week CES was once again held in Las Vegas with in excess of 100,000 people in attendance.
Cisco demonstrated a number of CMX and IoT related things this week.
Firstly “The Internet of Everything: On The Go”
In the Cisco booth some future thinking was applied with a concept that imagines the shopping experience with a simulated retail environment: “BigBox.” While shopping at BigBox, visitors can walk through a combination of experiences involving location-based data, video, predictive analytics, security cameras, and sensors – designed to help retailers enrich the shopping trip for their customers, and more efficiently manage their stores.
Somewhat scary for some and exciting for others, while all the time enabling retailer increase their bottom line and deliver improved and personalized shopping experience to the consumers.
The next demo “Starlight Resort” was a combination of CMX, and Small Cell capabilities in the hotel resort environment. Read More »

The holiday season which began with Cyber Monday on December 2nd 2013 has just ended and analyzing the impact on mobile commerce sales and location based services unveils some very interesting trends.
Firstly, at the macro level:
- Online shopping increased in the USA in 2013 by over 16% compared to 2012.
- From a mobility perspective, almost a third of all online sales (29%) were made from Smartphones or Tablets.
Clearly there are changes in the online marketplace, but in order to examine this a little further, let’s look at a few key questions to help understand what is happening in this marketplace:
- What are the major trends?
- Is mobile commerce just a US phenomenon?
- What impact does location based services have?
- Where are the main benefits coming from analytics?
- How is privacy fitting in to all this and how is the attitude of mobile consumers evolving?

CleanAir for 802.11ac: Why Spectrum Intelligence Still Matters
In wireless networking and communications, as with life, nothing good comes for free. It’s well known that the primary feature of the new IEEE 802.11ac amendment is support for an 80 MHz-wide channel. The benefit of an 80 MHz channel is the potential to double usable throughput in comparison to that of 802.11n using a 40 MHz wide channel.
However, what is less well known is that a wider RF channel is also more susceptible to interference. In other words, 802.11ac devices “hear more” than 802.11n devices, primarily due to the wider channel support. It should be noted that this is not a flaw in the 802.11ac amendment, it’s simply basic communications theory.
Nevertheless, there is far more to building an 802.11ac access point than simply meeting the standard. Not all 802.11ac access points perform equally without interference. But more importantly, not all 802.11ac access points perform well in the presence of interference.
Furthermore, there is far more to deploying High Density wireless LANs than only considering the performance of individual access points. Read More »
