A recent survey of over 200 IT professionals worldwide performed by BT’s Consulting Group says:
While many new technologies take years to be adopted, 802.11n appears to be exceeding the typical adoption curve. In fact, nearly one-third (31 percent) of respondents plan to migrate to 802.11n within the next 12 months, and another 20 percent plan to do so sometime beyond this timeframe.
The report says this speedy uptake indicates that the benefits of 11n are urgently needed. Unfortunately the survey didn’t appear to question respondents about their plans for 5 GHz operation.
The report delivered some other surprisingly optimistic numbers concerning FMC: 9% of respondents claim to have already implemented Fixed-Mobile-Convergence, and 32% plan to within the next 12 months. The report doesn’t specify how “Fixed Mobile Convergence” was defined in the survey. Since the survey was about WLANs, presumably it didn’t simply mean PBX extension to mobile, but I doubt that 9% of worldwide enterprises have implemented call continuity between WLAN and cellular.
The report has a lot of other interesting information - well worth a read.
