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!
With all that has recently been written about BYOD, it’s clear that enterprise IT managers need to consider performance requirements on the wireless access point. With more clients accessing the network, the performance demands in terms of coverage and client density will increase. Furthermore, consumer devices such as smartphones and tablets may have difficulty connecting to an AP compared to a laptop. This could be attributed to the fact that most of these devices either do not support 802.11n or they support legacy 802.11g/a. If the devices support 802.11n is sometimes limited to 1x1 MIMO. An access point that has superior performance will be needed to address the growing needs of these new clients.

It can be so easy to be mislead by vendors claiming incredible bandwidth gains offered by their new ’3 Spatial Streams’ wireless access points. The tricky part is that none of them are outright lying, they are simply describing a reality that nobody lives in. Cisco released the new 3600 series access points at CiscoLive London last week. We have also had fun showing the incredible bandwidth gains available through this extra stream -- but we did it with custom designed silicon to create a 4x4 radio. Why is this valuable to you? Is it not just ‘more is better?’ Hardly. The true genius being offered here is only clear when you understand some basics of how radios work. Multiple capabilities unique to Cisco come into play here such as ClientLink and CleanAir. Watch this ‘Fundamentals of Spatial Streams’ to arm yourself with knowledge you can apply right away. It will be the best 6 minutes of your life (today at least).
We often talk about business issues, customer care-abouts, productivity savings and the like on this channel, and sometimes philanthropy or esoterics, but mostly if you’re an engineer you have to deal with the technology, the installation, the support, and all the other stuff in terms of where the-rubber-hits-the-road.
When we post videos, we know people lose interest if they’re more than five minutes, so I’m glad it takes less than that to connect the gear up. A couple of cheats help of course -- like switching the radios on in the Cisco gear (they are shipped switched off for security reasons), and it helps to have a pre-charged battery available for the Intermec CK3. But then the video wouldn’t have made it onto the channel! We have quite a few customers with this kind of Warehouse technology.
Ok, so maybe you are starting to give in to the idea that, employees bringing personally owned tablets at work, is indeed not a fad and you have to deal with it. You have decided on a BYOD strategy that protects company and network resources, while (mostly?) satisfying user appetite for connectivity anywhere from any device.
Great! Now. Is your 802.11n wireless network capable of delivering the user experience that is associated with these new sleek gadgets?
If you thought your network is “good enough”, then think again. This client wave is about to disrupt everything in multiple ways.
First, more devices on the network translate to significantly higher demands for bandwidth. In many cases bandwidth requirements can grow exponentially because the ratio of user to devices is no longer 1:1 but 1:2 and often 1:3. We therefore expect to see network utilization significantly rise over time.
Second, tablet form factor now allows users to truly be mobile. Unlike laptops, users can now walk/move and be productive at the same time. This new type of behavior will increase the number of clients roaming between access points.
Finally, it has been observed that tablets are primarily used for content consumption (as opposed to creation), and video is one of the predominant types of content being consumed, which further complicates bandwidth issues, but also creates new challenges.
