Introduction

This Part defines the Physical Layer of the Airlink Interface between the Mobile Data Base Station (MDBS) and the Mobile End Systems (M-ESs).

Minimum performance requirements for MDBSs and M-ESs wishing to use this interface are defined in Part 408 and Part 409.

The Physical Layer is modelled on the requirements for cellular operation specified in EIA standards [EIA/IS-19], [EIA/IS-20], [EIA/TIA-54], [EIA/TIA-55], [EIA/TIA-56] and [EIA/TIA-553].
