The author worked with www.welchallyn.com in 1999 and 2000 when they were the first company in the patient monitoring industry to introduce 802.11FH for enterprise patient monitoring, (now 802.11a for next gen.). Then came Siemens (now Draeger)www.draeger.com and pretty much all the infusion device companies followed after that. Oh, let me not forget Sotera Wireless, www.soterawireless.com
However it seems that the market leader in patient monitoring still clings to to idea of a non-shared enterprise network and “proprietary legacy wireless technologies”. I guess let others inovate; then follow because they can.
While I agree that traditional embedded 802.11a/b/g/n can be somewhat power hungry, this is has pretty much fallen by the wayside with Low Power class=”zem_slink” title=”Bluetooth” href=”http://www.bluetooth.org/” rel=”homepage” target=”_blank”>Bluetooth and (ELP), Enhanced Low Power WIFI from TI. (see attached module). This is TI’s 6th generation WIFI module, and 7th generation Bluetooth module. They have been architected for co-existence on a single chip set. Looks like this would be ideal for a “patient worn device”…such as medical telemetry…or also what they say “patient worn monitor”.
I feel that the days of using “custom” radios for medical devices and the WMTS era is fading into the sunset just like the Black and White TV(s) and vacumn tubes of the 1960’s. Think I would leverage a 18 Billion$ company like Texas Instruments for my embedded WLAN chipset R&D development instead.
