Также немаловажную роль играет низкая излучаемая мощность радиопередатчиков абонентских устройств.
DSSS is Immediate Sequence Spread Spectrum Strategy that is a spread spectrum system where the data for being transmitted is encoded employing spreading code and received then decoded utilizing the same code.
It organizes engineering and business procedures into layers defined by actions happening, and it outlines how an business can create an interface to speak between these layers.
数字信号相乘，由于伪随机码速率快，扩展了传输带宽（伪随机码带宽远大于信号带宽，扩展信号频谱），在接收端，用相同的伪随机码序列
Multi-provider delivery delivers adaptability in handling transport operations. Firms can adapt to varying purchaser needs, take care of provider general performance, and make sure the most beneficial services amounts are taken care of across various regions and cargo forms.
Conclusion Multi-copyright shipping transcends the boundaries of an entire multi provider delivery operations strategy; it’s a flexible logistics solution which offers adaptability, cost-efficiency, and resilience throughout a spectrum of industries, enriched via the observe of comparative rate shopping.
