simplex or half-duplex modes using push-to-talk, and primarily intended to communicate with other radios rather than telephones. These

systems run on push-to-talk-based infrastructure such as Nextel's iDEN,

Specialized Mobile Radio (SMR), MPT-1327, Enhanced Specialized Mobile Radio (ESMR) or

conventional two-way systems. Certain modern two-way radio systems may have full-duplex

telephone capability.https://store.theartofservice.com/the-specialized-mobile-radio-toolkit.html
