Qualcomm described a new algorithm to lower the power of body area networks at a recent conference. The medical industry needs that to have sensors work 24/7 in regular living conditions without wireless packets getting lost.
EE Times' Rick Merritt reports from the conference that Qualcomm is one of many companies trying to surmount technical issues creating low cost and low power components to enable that vision.
Harinath Garudadri, an engineer in Qualcomm's corporate R&D group who oversees a team dedicated to health care issues pointed to a Harvard study called CodeBlue that found as many as half the packets transmitted are lost on multi-hop networks. "This is not acceptable in life and death situations," he said.
You bet it is.
Got any power management ideas for BANs (that's body area networks). Drop me a line.
