The migration to wireless LANS is very much underway in healthcare and many clinicians have moved away from the "traditional" desktop charting to the WIF-enabled laptop. Yankee Group, an analyst, predicts that in 2009, wired enterprise switch sales...

With the advent of 802.11n the use of MIMO with OFDM has become a reality. Here are two good papers from Keithly that help provide education surrounding this. The first is an introduction to Orthogonal Frequency Division Multiplex Technology. The...

1. Maximum frame rates are up to be 2700% higher than 802.11g to drive substantial improvements in forwarding performance for VoIP and TCP flows. 2. Maximum bit rates are up to 800% higher than 802.11g, increasing network capacity by improving forwarding performance...

While 802.11n has gained a lot of attention as the newest and the greatest; (technical people tend to graviate to the newest and greatest!) it is probably not the best fit technology for portable medical devices, i.e. patient monitoring, etc. or any other device...

The coverage patterns of 802.11a/b/g are mainly limited by attenuation and shadowing and are reletively predicitable. 802.1a/b/g specified a number of data rates and operating modes. The available data rates of a 802.11n MIMO link are dependent on the local scattering...

Power consumption for 802.11n devices will be significantly higher that for 802.a/g devices which are much higher than 802.11b devices. The key reasons why power consumption of 802.11a/g devices was much higher than 802.11b were (a) a more complex signal processing...
