TLDR
A protocol is described which allows a wireless access communication system (WACS) to dynamically allocate bandwidth on its system-wide broadcast radio channel among the alerting, system information, and priority access request subchannels, and efficiently accommodates a wide range of alerting traffic levels.Abstract:
A protocol is described which allows a wireless access communication system (WACS) to dynamically allocate bandwidth on its system-wide broadcast radio channel among the alerting, system information, and priority access request subchannels. These subchannels each have different requirements with respect to the message length and position within the framing structure; the described protocol meets each of their requirements. The protocol efficiently accommodates a wide range of alerting traffic levels, and provides for efficient downloading of system information to subscriber units by using excess capacity when alerting traffic is low. It has error detection capabilities above that provided by the radio channel alone, and is easily extendible to accommodate other services such as paging and low bandwidth broadcast messaging. This work is targeted towards understanding the implications to local exchange networks of wireless system alternatives that could provide access to those networks.read more

Universal digital portable radio communications
TL;DR: In this paper, the authors discuss limitations of the evolving approaches and consider objectives and approaches for providing more universal digital portable communications as an integrated part of telephone exchange networks, which can be accomplished by using demand-assigned radio links for the last thousand feet or so of telephone loops and sharing the remainder of the fixed distribution facilities.

A flexible low-delay TDMA frame structure
TL;DR: A low-delay TDMA (time division multiple access) frame structure is proposed to support low- delay speech coders in a 2-wire loop environment without requiring echo cancelers, which makes TDMA even more acceptable for early deployment in the loop plant.
