802.11ac is the hottest topic of discussion and deployment in WiFi over the past couple of years. Ratified as a standard by the IEEE in November 2013, the first phase of 802.11ac products brought to market is commonly referred to as Wave 1, and provides roughly a 3x improvement in network performance over its predecessor 802.11n: 1.3 Gbps compared to 450 Mbps in 5 GHz respectively when utilizing the maximum channel width and modulation supported .
Next up 11ac Wave 2, the next phase in 802.11ac, will begin entering the market later in 2015 in the form of both new client devices (smartphones, tablets, laptops) and new Access Points and modules, providing two significant enhancements building on Wave 1

The wireless world is going through rapid changes. 802.11ac, the fifth generation of WiFi, is poised for accelerated deployment which will dramatically change the user experience with more bandwidth, more speed and a higher number of concurrent client connections. In fact, nearly a quarter of all new access points in the enterprise are now 802.11ac, as suggested in a December 2014 Infonetics WLAN market report. Read More »

If you recall, back in the early days of 802.11n, the Wi-Fi Alliance (WFA) rolled out the 802.11n certification program in phases. Here we are several years later and in that same fashion, the WFA has split the IEEE 802.11ac specification into two certification phases: Wave 1 and Wave 2.
Last week we announced the availability of our 802.11ac Wave 1 Module for the 3600 Access Point and along with that, our intention to develop an 802.11ac adaptive radio module that will support the second phase of 802.11ac, or Wave 2. Most of the 802.11ac discussion in the last year has been focused on Wave 1, so we want to kick off the conversation about the second phase, Wave 2.
If Wave 1 promises increased wireless performance to address the increasing demand for higher performance including growing number of clients demanding higher performance for applications such as HD video streaming, then Wave 2 will stun you with its ability to provide even more throughput beyond the 1.3Gbps that Wave 1 provides as well as a number of other features that will further improve wireless connectivity. It is like taking a really good rock song and adding more cowbell to it.
SNL jokes aside, with the additional features packaged in Wave 2 comes the opportunity for further innovation in Cisco’s Wireless portfolio. We feel that it is important to stay ahead of the technology curve so that customers can plan and benefit from these advances sooner rather than later. So let’s discuss what features are coming with 802.11ac Wave 2. Read More »

802.11ac: The Fifth Generation of Wi-Fi Technology
In the last few months, there have been a lot of written on the emerging 802.11ac standard. This next generation of Wi-Fi promises to be very exciting since 802.11ac will address some critical pain points faced by users of 802.11n today – more bandwidth and more simultaneous users. To help explain the technology, we put together a new Fundamentals video. You’ll learn about new features such as:
- Operating in the 5GHz band
- Wider channels (80MHz & 160MHz) which means more capacity in the band
- Increased modulation with 256 QAM (Quadrature Amplitude Modulation), providing a significant increase in throughput over 802.11n which has 64 QAM
- Downlink Multi-User MIMO which allows an AP to transmit to multiple clients simultaneously
- Up to 8 Spatial streams which doubles the number of spatial streams used in 802.11n

We released our latest in the Fundamentals series earlier this month and it is trending quite well. The 802.11ac standard sounds like a step backwards alphabetically…but it will soon be an incredible step forward forward for WiFi once it is ratified by the IEEE. Watch this latest fundamentals to get comfortable with the truth. 802.11n is still your best bet for 2012 and into 2013 as we continue to partner on the standards process but the future is bright indeed!
