There are two types of radio networks currently in use around the world: the one-to-many broadcast network commonly used for public information and mass media entertainment; and the two-way type used more commonly for public safety and public services such as police, fire, taxicabs, and delivery services. Many of the same components and much of the same basic technology applies to both.

The Two-way type of radio network shares many of the same technologies and components as the Broadcast type radio network but is generally set up with fixed broadcast points (transmitters) with co-located receivers and mobile receivers/transmitters or Tran-ceivers. In this way both the fixed and mobile radio units can communicate with each other over broad geographic regions ranging in size from small single cities to entire states/provinces or countries. There are many ways in which multiple fixed transmit/receive sites can be interconnected to achieve the range of coverage required by the jurisdiction or authority implementing the system: conventional wireless links in numerous frequency bands, fibre-optic links, or micro-wave links. In all of these cases the signals are typically backhauled to a central switch of some type where the radio message is processed and resent (repeated) to all transmitter sites where it is required to be heard.

State Radio is an alternative rock band from Sherborn, Massachusetts, consisting of Chad Urmston (lead vocals, guitar), Chuck Fay (bass) and Mike Najarian (drums). The band's first full-length album, Us Against the Crown, was released in December 2005, their second, Year of the Crow in September 2007, and Let it Go, in September 2009. They have plans to release a fourth full-length album later in 2012.

A Boston based trio band led by singer and primary songwriter Chad Urmston (a former member of Vermont jamsters Dispatch), State Radio largely managed to avoid the usual post-Phish clichés, injecting a punk-influenced sound and politically charged viewpoint while staying true to the tenets of the band's chosen style, which infuses a blend of Roots-Reggae, Ska, Punk and Rock.

Urmston, who disbanded Dispatch at the height of its popularity in 2002, formed State Radio later the same year. Focusing exclusively on guitar and vocals instead of the instrument switching he was previously known for, he brought in second guitarist Pete Halby, bassist Chuck Fay, and drummer Mike Greenfield to round out the lineup. After the exploratory debut EP Flag of the Shiners was released by Fenway Recordings in late 2002, State Radio went on a temporary hiatus throughout 2003 as Urmston recovered from throat surgery. Returning to active duty in 2004 as a slimmed-down trio with new drummer Brian Sayers, State Radio followed a second EP, Simmer Kane, with the release of 2005's Us Against the Crown. Another personnel change occurred before State Radio toured in support of the album, with drummer Mike Najarian replacing Sayers.
