Imagine the ultimate battery-powered motorized propeller beanie
cap, which forms a wireless mesh network with other nearby
beanies! CapNet was deployed during the 2013 Design West Conference in San Jose, CA with more than 200 caps on the network.
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.
