摘　　要：在机场、港口和铁路调度站 ,有许多工作都高度依赖于无线通讯或者已采用了大量无线电设备的场合 ,如果建立Intranet无线局域网 ,并采用扩频技术 ,可以大大地提高自身抗干扰能力 ,而且对其他无线电系统无干扰。文中先讨论了Intranet无线局域网的扩展频率技术的特点与调制方式 ,描述了Intranet无线局域网的构成以及Intranet无线局域网中 3种站的特点 ;In the dispatcher's office of the airport, railway station and harbor, many jobs highly depend on radio communication and radio networks. A local radio Intranet supported by spectrum spreading technology helps to greatly improve its antijamming ability, and it will not produce any disturbance to other network systems. The characteristics of spectrum spreading technology and its modulate mode are described. The make-up of the local radio Intranet and three stations in this Intranet are also introduced. The WAVELAN radio network equipment is applied in this local radio Intranet.
