The FCC has issued two major documents concerning TETRA and the United States. The first document is the inital FCC Waiver, and the second document is the final Report and Order.
In the United States, with narrowbanding well underway, we envision three movements for professional radio users: one may remain using a narrowbanded analog signal, one may convert to DMR, or one may convert to TETRA. DMR may be considered a "mini-TETRA", however, there are certain features that DMR does not support that TETRA will easily accomplish. In this next section, we present papers from consultants discussing TETRA and DMR technologies.
