Digital Terminals for Packet Broadcasting.

摘要

Today's technology makes it possible to build small, personal digital radio terminals with low-power consumption. Studies have shown that such lightweight terminals can be efficiently supported by packet switched radio networks using random access modes and microprocessor controlled relays. Incorporating microprocessors into the personal terminals offers an opportunity to support wider ranges of user requirements and correspondingly reduce communication loads. The capability of new liquid crystal matrix displays, greater integration of CPU memory and other circuits, and thin film RF assemblies, reinforces the possibilities of fabricating these personal units. This paper discusses communication protocol and the state of the art of microprocessor technology in the design and development of compact digital terminals for distributed packet radio networks.
