One of the issues with powerline we had in the past, particularly in the home environment, is the different standards for powerline interference in different markets. In the EU the noise floor on the powerline at specific frequencies makes it difficult to deliver data at a reasonable baud rate. Wiring topology is also an issue in home. In the US sockets are all on spurs, compared to the ring-main in the UK. Additionally rooms can be on different 'phases', making intercommunication between rooms impossible. For these reasons, "end-user" installation of powerline control systems can have unpredictable success rates. In a new installation, particularly an office blocks for example, you may have better success. Rik.

I've always wondered just when I would be able to dim my home lights without the darned things going reddish on me, or having to have a dimable fluorescent of some sort... at a cost. LED lighting itself is a nifty advance, given the energy savings and dimming capability. The cost, well, the cost will do what costs do: decrease. However, the cost isn't an issue in some places. I have a pair of 65 watt floods sitting at a corner of my home, under an eave: about 30 feet in the air. I DON'T want to change those bulbs very often. The last change was to fluorescents last time the house was painted! But I purchased a pair of LED floods, and even at $65 each will be well worth the keeping off the ladder. And of course, the lifetime doesn't hurt at all. Power line dimming and color control sounds great: as devices drop into the mass market range, there will be all sorts of applications as well as basic dimming. It wouldn't hurt to extend fire detection throughout a home: even if only ever third fixture in my house could detect a fire, that's a much better coverage than my few smoke detectors. Lots of application and market it seems, on this one.

Powerline communication has been around for a while as an alternative of WiFi and traditional Ethernet. It has never been as popular as WiFi because of various reason. One of the main reasons is the cost of ownership. The cost of powerline communication scales according to number of PC required network access. Yet, the advantage of powerline communication is interference free from RF. The congestion of network is as well under control. With these benefits, marrying powerline communication and LED control seems to be the right choice to make. The product is particularly useful in concert hall where the decoration and lights are changed on every individual or band. The product will be able to reduce large amount of cable flying around, to help reduce the setup cost dramatically. The application may just be the beginning of the technology thriving. There will be more applications of powerline communication in the future to come.

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.
