PoE allows the wiring of a local area network (LAN) to carry both data and power to connected devices. Since 1962, it has been processing data on cancer incidence. Originally, it only collected data relating to cancer deaths. The Croatian National Cancer Registry was founded in 1959.

Using Power-over-Ethernet to Lower Retrofit LED Lighting Costs By Steven Keeping Contributed By Electronic Products The construction of a new building provides architects with an opportunity to embrace new technology to reduce the site’s lifetime carbon footprint. But, recently an alternative––which is particularly suited to modern office environments and which could significantly push down the cost of retrofitting SSL––has come to the fore: Power-over-Ethernet (PoE). Theses LED drivers add expense, take up space, and generate heat.

In contrast, LEDs require a low-voltage, constant-current DC supply, so connecting SSL to legacy wiring demands the use of specialized power supplies known as LED drivers. Conventional incandescent bulbs or fluorescent tubes run directly from the AC mains supply. 1 However, fitting SSL to existing buildings brings several challenges. Consumer electronics giant Apple, for example, has standardized on LED lighting for all facilities undergoing construction or major renovation.
