This review presents many RF transistor technologies for RFIC applications in cellular and personal communications service ( PCS ) markets. 介绍分析了在蜂窝和个人通信业务(PCS)市场中适用于RFIC的多种射频晶体管技术。
So far mobile access technology has been divided into four categories : personal communications, internet access, value-added service, entertainment and so on. 截至目前移动接入业务主要有以下四大类:个人通信,互联网接入,增值业务,娱乐等。
In the personal communications services ( PCS ) network, many database with large capacity are needed to provide terminal mobility, personal mobility and service mobility. Fast access user data can be used to control the intelligent network and then provide real time services. 在个人通信业务(PCS)网中,需要用大容量数据库以提供终端移动性、个人移动性和业务移动性,通过快速接入用户数据来控制智能网(IN),以提供实时业务。
Personal Communications Systems aim at global seamless communications, allowing anyone at any place and any time to communicate with anyone else in any form of service combination through personal communications networks and terminal capabilities. 个人通信业务(PCS)是以实现全球范围的无缝隙通信为目标,要求在任何时间、任何地点均能利用个人通信网络和终端能力,在任何用户之间实现多种业务组合的通信。
The goal of future mobile communications is personal communications, which means the users could access to the capabilities of the global network at anytime without regarding to the location and mobility and be provided with speech or high-rate data service. 未来移动通信技术的目标是个人通信,即实现任何人在任何时间、任何地点以任何方式的通信,提供话音和高速数据业务。
