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 very high data rates, GPRS-136 uses a 1.6 MHz bearer channel, also known as 136HS Indoor. 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 Indoor bearer channel, configured as a traffic channel (PTCH), for GPRS-136. An RLC/MAC entity for the 136HS Indoor bearer channel is specified in TIA/EIA-136-362 and a Physical Layer is specified in TIA/EIA-136-361.
