Bring Out Yer Dead: 5 Steps to Eliminate 802.11b From Your Networks

Now that US tax day is over, we in the wireless field can get back to focusing on P1: optimizing and maintaining network performance. Keeping your network in good shape is like gardening: if you don’t pull out the weeds, it’ll never look as good as it could. My friend Jim Florwick detailed the gory bits of the 802.11b penalty with its awful lag in efficiency and absolute waste of spectrum. I write today to help give you the steps to act on Jim’s order to stop the madness.

I liken this process to a memorable scene from Monty Python: You must “Bring out yer dead.” However much the first standard insists it’s still alive, let’s all be honest with ourselves: 802.11b is dead.

In memoriam of the first amendment to the IEEE 802.11 wireless networking standard hailing all the way since 1999, 802.11b was superseded by 802.11a and g in 2003 which are much more efficient.  802.11n was available in draft form in 2007 and was ratified in 2009 while 802.11ac was ratified last September. A few years from now we should be planning the wake for 802.11a and 802.11g as well.

Now is the right time to bury 802.11b and reduce the drag on your network. Let’s be real: there is a reason cyclists are not allowed on the freeway, and an 802.11b device will slow everyone down. Here are 5 easy steps for eradicating your network of 802.11b and getting on your way towards higher speed wireless:

STEP    1.         Identify any 802.11b devices on your network

All of the latest Wi-Fi connecting devices are 802.11a/b/g/n capable. So how do you hunt down the 802.11b-only devices? You’ll be looking for older laptop and mobile clients (mostly before the year 2005).

Cisco Prime Infrastructure makes this easy for you with a report on clients by protocol. It will look like this:

802.11n for Midmarket BYOD: Why now?

We’re in the midst of an incredible megatrend. We know it and we’re living it. We all love our mobile devices; whether it’s our laptop (yes, I’m sitting at my kids swim class typing away for work), our mobile phone (I’m getting texts on what’s for dinner), or our tablet (where Draw Something awaits me). Apple recently stated that they have sold more than 67 million iPads in the recent 18 months. That is more than all the Mac sales in the past 27 years. There’s no denying it:  we are in the midst of an incredible megatrend—a mobile megatrend.

But what does this mean to businesses?From the IT perspective, the role of the mobile devices has transformed from a luxury item used for personal communication and entertainment to an integral tool for employee productivity. Mobile devices are now the main platform for work (laptop or tablet) and the primary medium for corporate contact (mobile phone). With employees bringing an average of two mobile devices each (laptop/tablet + mobile phone), companies can reap the benefits of new business opportunities and more productive employees.
