Abstract: The present invention provides a base station architecture that is modular in configuration, lowering the initial cost of implementing a new CDMA telecommunication system for a defined geographical region while allowing for future capacity. The scalable architecture is assembled from a digital base station unit that is configured to support a plurality of simultaneous wireless calls connecting to a conventional public switched telephone network. For initial startup, two base station units are deployed for redundancy in case of a single failure. Additional base station units may be added when the need arises for extra traffic capacity. If sectorization is required, the base station units may be directionally oriented. Coupled to and remote from each base station unit are two amplified antenna modules that contain an omni-directional or an external directional antenna, a high power RF amplifier for transmitted frequencies and a low noise amplifier for received frequencies. A separate power supply module capable of supporting two base station units provides continued service in the event of a mains power outage.
Abstract translation: 本发明提供了一种模块化配置的基站架构,降低了为所定义的地理区域实施新的CDMA电信系统的初始成本,同时允许将来的容量。 可扩展架构由数字基站单元组合,数字基站单元被配置为支持连接到常规公共交换电话网络的多个同时无线呼叫。 对于初始启动,在单个故障的情况下,部署了两个基站单元以实现冗余。 当需要额外的流量时,可以添加额外的基站单元。 如果需要扇区化,则基站单元可以是定向的。 耦合到每个基站单元并且远离每个基站单元的两个放大天线模块包含全向或外部定向天线,用于发射频率的高功率RF放大器和用于接收频率的低噪声放大器。 能够支持两个基站单元的单独的电源模块在主电源中断的情况下提供持续的服务。

Abstract: The invention provides a spread spectrum communication system for maintaining an initial transmit power level of a communication station during periods of inactivity. The system comprises a first station (501) and a second station (502), the initial transmit power level of which is maintained, wherein the first station generates an automatic power control signal by comparing a measured noise power level in a communication channel and an estimated system transmit power level and the second station occasionally transmits a spread spectrum signal whilst in an inactive state and receives the automatic power control signal to adjust an initial transmit power level thereof.

Abstract: A parallel packetized intermodule arbitrated high speed control data bus system which allows high speed communications between microprocessor modules in a more complex digital processing environment. The system features a simplified hardware architecture featuring fast FIFO queuing operating at 12.5 MHz, TTL CMOS compatible level clocking signals, single bus master arbitration, synchronous clocking, DMA, and unique module addressing for multiprocessor systems. The system includes a parallel data bus with sharing bus masters residing on each processing module decreeing the communication and data transfer protocols. Bus arbitration is performed over a dedicated serial arbitration line and each requesting module competes for access to the parallel data bus by placing the address of the requesting module on the arbitration line and monitoring the arbitration line for collisions.
