Squeezebox Radio. Squeezebox Radio adds a color screen (2.4") to the all-in-one design of its older sibling, Squeezebox Boom, but only in a mono configuration. The Squeezebox Radio can be powered by an optional proprietary battery pack, made available in March 2010. When running off Logitech Media Server, two Squeezebox Radios can be ...
A cognitive radio (CR) is a radio that can be programmed and configured dynamically to use the best channels in its vicinity to avoid user interference and congestion. Such a radio automatically detects available channels, then accordingly changes its transmission or reception parameters to allow more concurrent wireless communications in a given band at one location.
The Icom ID-1 1.3 GHz mobile radio was released in late 2004. The ID-1 was the first D-STAR radio that provided digital data (DD) mode operation. In this mode, data can be transferred at 128 kbit/s as a wireless bridge via the RJ-45 Ethernet jack on the radios. It was the only radio to provide this function until the release of the IC-9700 in 2019.
A land mobile radio system (LMRS) is a person-to-person voice communication system consisting of two-way radio transceivers (an audio transmitter and receiver in one unit) which can be stationary (base station units), mobile (installed in vehicles), or portable (handheld transceivers e.g. "walkie-talkies").
Z-Wave is a wireless communications protocol used primarily for residential and commercial building automation. It is a mesh network using low-energy radio waves to communicate from device to device, [2] allowing for wireless control of smart home devices, such as smart lights, security systems, thermostats, sensors, smart door locks, and garage door openers.
A four-channel radio switch and radio-to-power-line transponder To allow for wireless keypads, remote switches, motion sensors, et cetera, an RF protocol is also defined. 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 ...
Satellite radio is defined by the International Telecommunication Union (ITU)'s ITU Radio Regulations (RR) as a broadcasting-satellite service. [1] The satellite's signals are broadcast nationwide, across a much wider geographical area than terrestrial radio stations, and the service is primarily intended for the occupants of motor vehicles.
MTS features, including stereo and SAP, travel on subcarriers of the video carrier, much like color for television.It is not carried on the audio carrier in the manner of stereo sound for an FM radio broadcast, however, as it only has a frequency deviation of ±25 kHz, whereas regular FM broadcasting has a deviation of ±75 kHz.
