个人通信业务概况及市场发展趋势

The Personal Communications Services Overview and Its Market Trends

个人通信业务(PCS)是美国蜂窝行业为了解决早期蜂窝业务中存在的问题而提出的,但是随着技术的进步,蜂窝业务已经得到了较大的改善,个人通信业务与蜂窝业务之间的差异已经越来越模糊.另外,随着频谱拍卖和网络建设的逐步完成,个人通信业务市场正式启动.美国各主要市场都至少出现了1～3个新的个人通信业务运营者,这些运营者将与相应市场上的两个运作多年的蜂窝业务供应商竞争.文章详细介绍个人通信业务,并简要分析个人通信业务的市场发展前景.

When Personal Communications Services (PCS) were first conceived, many analysts expected that they would compensate for some of the weaknesses of cellular telephones-problems such as high prices,bulky equipment,the need for battery power,and the interference cellular users experience in congested and remote areas. However, before the first PCS services could be introduced, a significant reduction in the size of cellular handsets and improvements in battery capacity allowed cellular telephones to be used in the same way that forecasters initially expected PCS handsets to be used.Over the long term, PCS will become an anytime/ anywhere communications service, and will include the integration of all telecommunications services currently offered by wireline and wireless networks. Southwestern Bell and GTE are already offering Tele-Go,a service that combines wireless and wireline services. Tele-Go, which allows subscribers to use one device to access both cellular and traditional wireline services, has been well received despite the fact that it does not offer some of the advanced features that will be possible when PCS providers beg-ing to use Intelligent Network capabilities.
