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.
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. Read More »
At WWDC this week, Apple announced that their new Macbook and Macbook Air are 802.11ac enabled. As we predicted in our red-hot Client Adoption blog earlier this year, the list of 802.11ac clients, like the new Macbooks and Samsung Galaxy S4, will continue to grow and expand throughout 2013. These devices come with the promise of Gigabit wireless, at faster speeds and better performance. How will your enterprise networks meet those expectations? The Cisco Aironet 3600 with 802.11ac module is your ticket for enterprise-class 802.11ac wireless.
Cisco Aironet 3600 AP with 802.11ac module
The 802.11ac module will make these new clients fly at new higher speeds--3 to 4 times faster than 802.11n. So if you are connecting your new Apple device to an Enterprise Network supporting Cisco’s 3600 AP with the 802.11ac module, you will be able to get some of the highest bandwidth rates ever seen out of your Wi-Fi network which will open the opportunity for better quality video streams, better online collaboration and the support of more high-bandwidth demanding applications.

Can’t get enough of 802.11ac? Neither can we. Read More »
In this week’s episode of Engineers Unplugged, we hear from VMware’s Andre Leibovici (@andreleibovici) and Chuck Hirstius (@rexremus) as they discuss how to Be Kind to Your Protocol, including solutions to common problems and the art of tuning.
Welcome to Engineers Unplugged, where technologists talk to each other the way they know best, with a whiteboard. The rules are simple:
Episodes will publish weekly (or as close to it as we can manage)

The question isn’t IF your users will need more bandwidth, but WHEN they will need more bandwidth. 802.11ac represents the next evolution of the 802.11 standard, and, as you’ve heard, this one really pegs the gas petal in the quest for speed. Offering a link-rate of up to 1.3Gbps, 802.11ac represents the first wireless standard that surpasses the gigabit barrier.
But what makes 802.11ac unique isn’t just bandwidth. The new standard represents a forced push to the cleaner 5GHz spectrum, as well as extended battery life, made possible by getting devices on and off the air more quickly. To learn more about the technical details under the hood of 802.11ac reference this whitepaper.
Cisco’s Aironet Access Point 3600 and an alpha version of the 802.11ac module were demonstrated during Cisco’s presentation during Wireless Field Day 3 (the demo occurs at timestamp 15:30 in the video). Keep in mind that this is a demonstration of a pre-released product so it is expected that throughput and functionality will change and likely increase when the product is available for customers in early 2013.
The test goal was to measure one client, one Access Point 802.11ac performance and leveraged Ixia’s IxChariot to generate UDP traffic over the air. The test was done in an open real world environment, so the achieved throughput is less than what would be expected in a clean RF environment typical of a benchmark test.
There are many challenges IT managers face on a daily basis. As the proliferation of user devices and the growth in business, personal and collaborative applications continue to grow, almost exponentially, these challenges only make the job of an IT manager harder. For instance, imagine what goes through the mind of an IT administrator who is responsible for helping a hospital and medical school get a handle on device and application growth and usage:
Is a guest or patient downloading movies using Bit-Torrent –in other words, stealing valuable airtime away from my mission-critical applications?
My network supports a mixed use of guests, employees and vendors/doctors. Without prioritizing applications on the network, employees risk losing productivity and response time to patients, insurance providers, labs. Can I prioritize business-class applications such as Cisco Webex/Jabber and de-prioritize the applications such as Netflix?
Who are my top 10 users and the top 10 upstream and downstream applications? Can I save a detailed report of all application flows in my network for compliance purposes?
The number of devices, number of users is exploding, and use of video is growing 50% year over year. Should I add more access points in my auditorium or conference room areas? Or should I upgrade to 802.11ac for more capacity?
