Summary: What Next-Generation Wi-Fi Models Could Mean for Secure Mobility

With the adoption of the Internet of Things and Internet of Everything, advances in mobility and next-generation Wi-Fi are driving faster speeds, higher signal quality and more reliable connectivity, but how are they changing the way we think about mobile security?

As more people connect to both wired and wireless networks via smart phones, tablets and laptops, security will continue to be a top concern. New Wi-Fi models, such as Beamforming and Wi-Fi Direct, are helping drive mobile devices to the faster, more secure 5GHz band, therefore offering secure ways to enable the Internet of Everything to connect more people, processes, data and things.

As mobility trends drive new expectations from networks, a strategic and architectural approach to secure mobility is essential, and next-generation Wi-Fi makes this possible.

What Next-Generation Wi-Fi Models Could Mean for Secure Mobility

With the adoption of the Internet of Things and Internet of Everything, advances in mobility and next-generation Wi-Fi are driving faster speeds, higher signal quality and more reliable connectivity. With the upcoming ratification of the two waves of the 802.11ac Wi-Fi standard, how are emerging Wi-Fi models creating new security features that are defining the next-generation Wi-Fi experience?

Next Generation Wi-Fi Models

Migration to the 5 GHz-only 802.11ac is quickly becoming a reality. In a recent article by Lisa Phifer, Chris Spain, Vice President of Product Marketing for Cisco’s Wireless Networking Group, discusses more about how this migration will drive a shift in mobile device support for 5 GHz. “An increasing percentage of new mobile devices provide dual-band capability, and they generally prefer the less congested 5 GHz band,” Spain said. New Wi-Fi models, like those listed below, can help drive mobile devices to the 5GHz band:

Miercom: Cisco Aironet AP3702i

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 4x4 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 3x3 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.

Multi-Client Performance

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’.

6 Tips for High Density Network Design

The guys from No Strings Attached Show just published their podcast we sponsored featuring Jim Florwick yesterday and already the verdict is in: Jim Florwick is awesome.

For those of you who haven’t had the chance to download the podcast yet (What are you waiting for?! Download  podcast) or you have a few extra minutes to scan a short blog to decide whether or not you want to download the podcast, I asked Jim what his key takeaways are when it comes to high density design.

Here are Jim Florwick’s 6 tips for HD network design (for the REAL meat, tune into the podcast):

  1. High density client environments are quite common with today’s users being very connected – today’s users are always connected.  With planning, this can be managed quite successfully.  Understand the limitations, be aware of how legacy requirements will affect the outcome, and set expectations accordingly. Efficiency is key and removing some of the blockers (legacy) first is essential.
  2. 802.11ac represents another quantum leap forward in technology and will eventually allow a much richer user experience.   It is a transition that must be managed and balanced against your current mission requirements.  Evaluate channel/bandwidth requirements carefully.  Monitor the mix of client devices operating in your environment and update frequently.
