When used to describe aircraft radio cockpit radio systems, the control panel is often called the radio head. In wireless system technologies such as GSM, CDMA, UMTS, LTE, 5G NR this radio equipment is remote to baseband units [1] such as BTS/NodeB/eNodeB/gNodeB or gNB. This equipment is used to extend the coverage of a baseband unit in ...

X10 wireless devices send data packets that are nearly identical to the NEC IR protocol used by many IR remotes, and a radio receiver then provides a bridge which translates these radio packets to ordinary X10 power line control packets. The wireless protocol operates at a frequency of 310 MHz in the U.S. and 433.92 MHz in European systems.
