re: Cisco rolls more routers for smart grids

Why is the radiation level 60-150 times higher than cell phone? I think the data is just for logging power related information which shouldn't be heavy traffic so I wonder even the transmitter on the meter doesn't need to dump data all the time. Besides, the transmitter should have been placed in areas not be easily touched. With much farther from human, I wonder how this radiation is different from the sea of micro-wave that we expose to every day (remember there are lots of base-stations and repeaters transmitting energy out to "talk" to all phones around).

Why not to use their own line they have for metering purpose, instead of using wireless links. PLCC will be the best option for this with some amendments.

With CISCO getting into this, we can be assured that smart metering is entering phase 2.

HOW WILL CISCO AND OTHERS CONTINUE TO WORK IN THIS AREA NOW THAT A CALIFORNIA HEALTH DEPARTMENT IDENTIFIED SMART METERS AS DANGEROUS TO PERSONAL AND PUBLIC HEALTH? CALIFORNIA HEALTH DEPARTMENT SMART METER HEALTH REPORT JANUARY 2012 (summary). 1. Smart Meters emit radiation almost continuously, day and night, seven days a week. 2. Family safety is uncertain with a smart meter attached to a home. 3. It is impossible to know how close a consumer is to their RF Radiation limit, making safety an uncertainty with installation of a mandatory Smart Meter. 4. Smart Meters can exceed the whole body radiation exposure of cell phones by 60-150 times. 5. Radiation exposure from Smart Meters at non-thermal levels shows accumulating evidence of human cell damage, DNA chain breaks, breaches in the blood-brain barrier, sperm damage, toxin exposure, cancer, miscarriage, birth defects, semen degradation, autoimmune diseases, etc. 6. Electromagnetic hypersensitivity (EHS) is a real and sometimes debilitating neurological problem for the affected persons (Mild et al., 2004). 7. FCC guidelines do not protect the public and cannot be used for any claims of Smart Meter safety. 8. Smart Meters exceed the RF Microwave Radiation standards of many other countries by 12 to 60 million times. 9. SUMMARY: Given the evidence of existing and potential harm from Smart Meters, governmental agencies for protecting public health and safety should be much more vigilant towards Smart Meter electromagnetic radiation exposures because governmental agencies are the only defense against such involuntary exposure.

Now we just need to have easy to use power management/control systems within the home or building to better understand what power we are using- ideally on a device basis.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
