Editing Broadband (section)

===Alternative technologies===
[[Power line communication|Power lines]] have also been used for various types of [[data communication]]. Although some systems for remote control are based on [[narrowband]] signaling, modern high-speed systems use broadband signaling to achieve very high data rates. One example is the [[ITU-T]] [[G.hn]] standard, which provides a way to create a [[local area network]] up to 1 Gigabit/s (which is considered high-speed as of 2014) using existing home business and home wiring (including power lines, but also phone lines and [[Ethernet over coax|coaxial cables]]).

In 2014, researchers at [[Korea Advanced Institute of Science and Technology]] made developments on the creation of ultra-shallow broadband [[optical instruments]].<ref>{{cite web |url=http://phys.org/news/2014-12-broadband-ultrathin-polarization.html |title=Broadband and ultrathin polarization manipulators developed |publisher=Phys.org |date=2014-12-04 |access-date=2016-06-21 |url-status=live |archive-url=https://web.archive.org/web/20160515051917/http://phys.org/news/2014-12-broadband-ultrathin-polarization.html |archive-date=2016-05-15 }}</ref>
