The next generation of Wi-Fi, 802.11ac couples the freedom of wireless with the speed of gigabit Ethernet. This also translates in additional load on the backbone of the network, which has to deliver at least 3 times the capacity of the current gold standard, the 802.11n based network.
Cisco launched the Unified Access architecture to scale linearly with the increased load on the network with 60 Gbps Wi-Fi throughput on the Cisco 5760 Wireless LAN Controller and 40 Gbps Wi-Fi throughput on the Catalyst 3850 Series Switch with a built-in wireless controller. Both these platforms are based on the Cisco Unified Access Data Plane (UADP) programmable ASIC, which provides high performance and scale, common open APIs, and enables consistent QoS policies for both wired and wireless networks.
Aruba recently launched the 7240 series controllers with a throughput of up to 40Gbps claimed, with the same goal of delivering 802.11ac capable performance across the network. This controller is based on a generic network processor and not a purpose built ASIC like the Cisco controller.
Miercom performed a third-party evaluation to benchmark these products using IMIX (Internet Mix) packet traffic and test QoS traffic for high priority application. IMIX is traffic pattern consisting of a preset mixture of small, medium and large frame sizes used to emulate real-world traffic scenarios in a testing environment. We wanted to give you a sneak peek at some of the results.
Cisco 5760 is six times faster and Catalyst 3850 is 4 times faster as compared to Aruba 7240
The Cisco 5760, 3850 and the Aruba 7240 were tested for throughput using RFC 2544 and IMIX Traffic. The Cisco 5760 and 3850 performed extremely well by achieving 50 Gbps and 37 Gbps, whereas Aruba 7240 fell short by just achieving 8 Gbps, which is 20% of its advertised throughput.

Coming off a busy week at Interop Las Vegas, we have recorded another info-packed podcast with the popular wireless networking podcast group “No Strings Attached Show”. The topic for this podcast covers the gigabit wireless technology, 802.11ac which if you attended Interop, you know this is a very hot topic (“I’ll take enormous understatements for $600, Alex”).
However, it is not just a discussion on what is included in the standard. Blake Krone and Sam Clements from No Strings Attached interview our Mark Denny and Brian Hart as they discuss a number of topics related to 802.11ac technology including the following:
- The 802.11ac Wave 1 Radio Module for the 3600 Access Point, the availability and best practices for upgrading the 3600 AP with the 802.11ac Module
- Segments of the enterprise market where 802.11ac technology is generating the most interest Read More »

When natural disasters strike, our first instincts are to phone or text loved ones; check news and social media sites; and go online to lend support. These connections become our lifelines. In the process, mobile devices become paramount in connecting people to people and people to data.
That’s why the Internet of Everything (IoE) is so critical. In the moments immediately following a disaster popular social media networks, like Facebook and Twitter, serve as quick ways to locate loved ones. At the same time, social media allows those affected to inform multiple people at once that they are okay, with a simple tweet or post. Read More »

Location Services has been a holy grail in many industries for almost 5 years now and none more so that in the retail industry. In recent discussions with Chief Executive Officers in leading retailers especially those from a marketing or operations persecutive some interesting comments and trends are emerging.
Retail & Location Analytics
Firstly about a year ago retailers were looking at LBS and saying we must have this, were unsure how to use it to effectively drive their business.
Today in April & May 2013 these executives are equally as excited about the possibilities location services brings to their business, however they are also putting an even greater focus on the ROI. When vying for capex resources a compelling business case is one that has a clear return on the investments needed. When considering a guest WiFi deployment and associated location based services the business cases emerging are varied especially when speaking with some global retailers. Read More »

It’s no surprise that student safety is the upmost priority to educators, administration, and parents. I would know because I have two daughters in K-12. The topic of safety in K-12 schools strikes particularly close to home since one of my daughters has already been in a lockdown due to police activity in the area. A lockdown is where children are placed in the corners of the classrooms, away from windows and clear from the classroom door windows: lights off, doors locked, and no chatter. My daughter took it in stride since she thought it was a game. I, on the other hand, was extremely uneasy when I received the email bearing the news and was not relieved until I received the “clear” email notification.
Given some of the latest developments that Cisco has been working on with location-based analytics using wireless technologies, it didn’t take long for us to start talking about how Wi-Fi could be used to help in the case of public safety in K-12 schools. The intersection of K-12 public safety and Wi-Fi technologies stirred up such a discussion amongst ourselves that we wanted to open up the discussion with an external webinar. I hope you can join me for the discussion on May 22nd (Click to register), but just in case you need some convincing, here’s a teaser. Read More »
