Introduction

GPRS-136 is the packet data service provided in TIA/EIA-136 (also known as UWC-136). A general description of the System Architecture and Protocol Descriptions is provided in TIA/EIA-136-330.

To provide high data rates, GPRS-136 uses a 200 kHz channel, also known as a 136HS Outdoor bearer. The upper layers of the GPRS-136 protocol stack are common throughout UWC-136, applying to each individual bearer (136+, 136HS Outdoor, and 136HS Indoor). This document provides an Overview of the 136HS Outdoor bearer, configured as a packet traffic channel (PTCH), for GPRS-136. An RLC/MAC entity for the 136HS Outdoor bearer is specified in TIA/EIA-136-342 and a Physical Layer is specified in TIA/EIA-136-341.
