Market Overview

• PMR/PAMR markets stable against threat of GSM
• Sub-audio In-band signalling instrumental in
  PMR success
• MPT 1327 trunking specification provided boost to
  the industry fuelling PAMR development

• CML FRS Market expanding
• Market is heading towards digital architecture
• TETRA networks becoming established
• Services favour digital systems (UK Police force
  choose TETRA)
• NSC withdrawing from market (SC11372 PMR
  Processor)
