I’ve recently been talking a lot about ubiquitous mobility, that future-state when folks in an organization are all wireless, all the time. We’re not there yet, but I regularly urge enterprise IT managers to think about this future state and consider how soon they want to reach it when making strategic investment decisions.

It turns out there is some public data to point to a more ecological push for enabling mobility in the enterprise. The Texas Transportation Institute recently released a study examining the benefits of mobile employees over those that commute to an office. At peak congestion times, workers traveling to an office expend "an extra 38 hours of travel time and consume an additional 26 gallons of fuel, amounting to a cost of $710 per traveler." Numbers to put the cost of investing in a WLAN refresh, even one based on 802.11n, in clearer focus.
