Wi-Fi & Taxes: Digging into the 802.11b Penalty

It’s that time of year again in the US – Tax Time!  That time of year where we review the previous year’s bounty, calculate what’s due, and re-evaluate our strategies to see if we can keep more of what we worked for.  Things change; rules, the economy, time to retirement, and before you know it you find yourself working through alternatives and making some new decisions.

Anyway, as I was working through the schedules and rule sheets, my mind wandered and I started to think about Wi-Fi and the taxes associated with it.  In my day job, I often play the role of forensic accountant.  Like a tax accountant, I’m always looking for a way to get more or understand why there isn’t more already.  So along those lines, lets talk about a little known tax that you may well be paying needlessly.  I’m talking of course about the dreaded 802.11b Penalty.

Wi-Fi protocols like 802.11b are referenced by standards committees for the workgroup that develops them.  In the 2.4 GHz spectrum, there is 802.11b, 802.11g, and 802.11n.  Back in 1997, 802.11b  was the first modern Wi-Fi protocol ratified by the IEEE and it allowed transmissions of 11 Mbps, a major jump forward from the previous 2 Mbps  that was possible with the original 802.11 standard.

After 802.11b came 802.11a, and then 802.11g.  Both of these protocols where a radical departure from the simplistic 802.11b structure and employed Orthogonal frequency-division multiplexing (OFDM) modulation (now standard in every 802.11 protocol created since then).  OFDM allowed for Read More »

Increasing Demand for Higher Location Data Resolution

Cisco has been playing a critical part for retail, healthcare, hospitality and transportation organizations to gain an understanding of how end-users move throughout an organization’s physical location. This is done through our Cisco Connected Mobile Experiences (CMX) solution.

With all the valuable information CMX provides, the demand for even more accurate data has been growing. Location accuracy has been a hot developing field and, as I mentioned in announcing our Best of Interop Finalist status in the wireless category last week, Cisco’s taken the lead in redefining how this location-based data is acquired.

In the past many solutions have relied on the probing performed by the mobile device to acquire location-based data.  In recent months this approach has shown diminishing returns. The underlying issue is that this data is reliant on how frequently the mobile device probes an access point. A couple issues that arise include:

-       Mobile device manufacturers are reducing the frequency of device probing to conserve battery. This reduces the number of data points collected and impacts the accuracy of the data

-       Different manufacturers probe the access point with varying frequency so some devices deliver more accurate information than others skewing the location analytics data.

At Cisco’s annual Partner Summit event we are revealing some key areas of focus for the upcoming Cisco v8.0 release. Although the list is not inclusive of all new functionality, I would like to highlight some steps we are taking to bring CMX to meet the ever-evolving demand for location-based data.
