系统容量 ：在保证通信质量的前提下，功率控制算法能够支持的用户数量和数据传输速率。
开环功率控制 ： 开环功率控制是基于接收信号强度的预测进行的，它不需要反馈信息。在移动终端接入网络时，会根据信号的衰落特性预先设定发射功率。开环控制主要用于解决信号在传播过程中遇到的路径损耗问题。
3GPP2 specialized requirements and experiences are available to the general public free of charge, solitary-use download, supplied the documents will not be reproduced possibly in part or in entirety.
移动通信中，将话音信号转换为数字信号，给每组数据话音分组增加一个地址，进行扰码处理，并且将它发射到空中。
The Walsh space not devoted to broadcast channels around the BTS sector is obtainable for site visitors channels. These channels have the individual voice and data calls supported by IS-95. Such as the paging channel, targeted visitors channels Possess a frame time of 20ms.
Diverse carriers provide different return possibilities. While some carriers have more cost-effective return selections, They could not have quite possibly the most robust solutions to account for every form of return. As an example, USPS Top quality Mail is really a baseline for affordably obtaining returned items under 16 ounces.
Гибкое распределение ресурсов. При кодовом разделении нет строгого ограничения на число каналов. С увеличением числа абонентов постепенно возрастает вероятность ошибок декодирования, что ведёт к снижению качества канала, но не к отказу обслуживания.
Whether you’re a logistics supervisor, a provide chain Specialist, or an executive having an active desire while in the perpetual well being of your business, this tutorial will offer valuable insights in the transformative likely of multi-provider shipping. Knowledge Multi-copyright Transport & Prices
EVDO services are offered from mobile network operators or other telecom or World wide web vendors. Being a consumer, you may access EVDO by means of your mobile phone or possibly a data card (mobile broadband router, e.g. Mi-Fi device). When utilizing EVDO by way IS-856 of a data card, based on the device producer, you might have to put in program within the support service provider to connect to the world wide web. EVDO is a network decision that enables mobile operators to provide data-only services that may co-exist with their voice services.
接收端处理： 移动终端接收多个载波上的信号，进行相应的处理以恢复数据。
Evolution Data Only (EVDO) is usually a telecommunications standard get more info for your wi-fi transmission of data via radio indicators, mostly useful for broadband Web access.
The spherical trip hold off involving A and B is 80 milliseconds as well as the bottleneck bandwidth on the path more info between A and B is 128 kbps. Exactly what is the opt
Emergency Services: EVDO played a role in supporting mobile data interaction for emergency services, enabling initially responders to access vital information and coordinate rescue attempts in real time.
预测模型的优化 ：通过机器学习等先进技术来预测无线环境的变化，实现更为智能的开环控制。
