(PACS)* Personal Access Communications System Advantages Perceived by Proponents

• Wireline-equivalent service quality, but with mobility

  • 32 Kbps ADPCM (G.721)
  • Low transmission delay (᝺ms round trip)
  • High data rate

• Microcellular

  • But supports vehicular mobility (65 mph)
  • Small radio ports
  • Handsets have 5+ hour talk times

• Low Cost

  • Subscriber units
  • Radio ports
  • Radio controllers

• Ideal for wireless local loop

*PACS is considered a low-tier PCS technology: low power and low complexity
