If you are an Enterprise IT Manager, this is a question that you must ask yourself if you are considering deploying 802.11ac for your enterprise wireless network. 802.11ac has some great benefits such as wirelike speed and being able to handle a high concentration of clients. However, there is more to consider when deploying 802.11ac. For instance, how do I handle RF interference now that 802.11ac support 80MHz channels? Will legacy devices such as 802.11g/a/n allow me to achieve the best performance that 802.11ac advertises? How can I ensure that my users get the best wireless performance when they roam across a building? And lastly, as more clients join the network, is my performance going to suffer? These are all valid concerns and are something that Cisco addresses with HDX. HDX is High Density Experience and is part of Cisco’s 802.11ac solution. We just wrapped up a 4 part blog series on HDX where we answer these questions:
– For Interference Mitigation, we have CleanAir for 80MHz Channels
– Getting the best performance out of your network even with legacy clients, we have ClientLink 3.0 Read More »

Cisco’s newest 802.11ac product, the Aironet 3700 Series Access Point is now orderable and shipping in the next few weeks. The AP 3700 features an integrated 11ac radio with a 4×4 architecture and Cisco’s High-Density Experience (HDX) Technology. HDX is a suite of features specific to the AP 3700 that delivers the best possible user experience, especially in high client density networks. HDX is enabled by a combination of hardware and software features on the AP 3700, features including:
- CleanAir 80 MHz – Interference detection and mitigation
- ClientLink 3.0 – RF link quality
- Smart Roam – Intelligent roaming handoff
- Turbo Performance – Performance with high client density
Aruba recently launched their 802.11ac access point, the AP-220 series, featuring a 3×3 design.
Miercom recently published a third-party evaluation of the performance between the AP 3702i and the AP-225. The report consists of a diverse range of test cases meant to gauge real-world performance of the access points. The tests include; multi-client performance, single client rate vs. range, performance in the presence of interference, and performance on reduced power. Here are some of the highlights from the report.
The AP 3700 performed very well in the multi-client performance test, thanks impart to HDX Turbo Performance. With 60 clients, the AP 3702i had a 6x performance advantage over the AP-225. The AP-225 struggled to serve all the clients and only mustered 40 Mbps total. The AP 3702i was able to transmit a healthy 236 Mbps, while maintaining fair throughput to each client.
The test consisted of 60 11ac clients, all associated to the 5 GHz radio. The clients used were 10 Dell E6430 laptops with Broadcom 4360 three spatial-stream chips, 20 Apple Macbook Air two spatial-stream laptops, and 30 Dell E6430 laptops with Intel 7260 two spatial-stream chips. Clients were setup in an open office environment surrounding the AP. Distances varied from 10’ to 50’.

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.

The number of mobile-connected devices has broken the 1 billion mark. That’s not too surprising, given that as we grow more reliant on our devices and mobility, we also become more reliant on the Internet to get things done, take care of customers, and expand our businesses. In fact, we see a future that is defined by what we call the Internet of Everything (IoE), bringing together people, processes, data, and things to make networked connections more relevant and valuable than ever before. Yet Cisco estimates that about 99.4 percent of what could be connected by the Internet is currently unconnected. That’s pretty staggering. Imagine how even a fraction of that could affect your business—by connecting employees when they’re mobile and connecting customers and partners to keep business processes and sales in progress.
Cisco’s latest offerings are designed to capitalize on connectivity, helping to fuel small business success and pave the way for future growth.
Lief Keopsel recently discussed how the growing mobile population calls for a new approach. Cisco’s expanding small business portfolio helps customers find the right technology to meet their evolving needs—such as increasing overall productivity, bolstering responsiveness, and beating the competition. But we haven’t stopped there. We’ve recently added additional routers and wireless access points.
Ultimately, we’re developing a portfolio that helps small businesses perform to their maximum potential through offerings that span security, connectivity, and collaboration.
Security Is a Competitive Advantage
Through all this, whether you’re increasing productivity or enabling collaboration, you really have to keep security at the forefront. It’s what gives you the edge. If you missed the recent blog post featuring David Lawrence from Smart Technology Enablers talking about the Cisco ISA500 Series, please listen in. David describes how the Cisco ISA500 Series helps customers safeguard against outside threats while allowing employees to securely access information remotely.
Connectivity Is Key to Productivity
Check out how our newly launched products deliver greater capabilities with built-in intelligence to provide more options for getting things done and creating a more customer-centric business model, regardless of location.
Collaboration Improves Business Effectiveness
Bringing together people is a key part of our value proposition. We’re helping small businesses respond to customers more quickly and cultivate stronger customer engagement and loyalty. All while lowering the cost of doing business.
We understand that making the right technology decision is critical. And to that point, we’re proud of the recognition we’ve received from Miercom. Linda Beaton’s post on February 8 highlights a recent study by Miercom. This report favorably compared the Cisco SF500, SG500, and SG500X switches with similar products offered by HP, D-Link, and Netgear.

Daily, we read about and experience the increasing importance of mobility and cloud offerings in the SMB market—and inherent in these trends is the capacity to configure appropriate switches. Tablets, smartphones and laptops are prevalent in the workplace and as SMBs often forgo funding an IT department, it is crucial that their hardware and solutions scale as business transforms.
That said, a recent testing report conducted by Miercom details how Cisco SMB Ethernet switches outperform those of HP and D-Link across the board. From overall performance and price to security, ease of use, and energy efficiency, Cisco’s switches are raising the bar. Highlights from the report include:
