所谓“第三代”移动通信就是指它具有宽带业务的能力,而无线宽带业务无非是移动中的高速数据通信与动态视频业务。但是,限制它市场需求的因素很多: 首先,移动中的高速数据通信市场非常狭小,因为绝大多数数据通信业务(电子邮件、短信息、炒股等)完全可以通过目前的窄带移动通信实现。就像在攀登珠穆朗玛峰时使用铱星系统一样,

However, there are many factors that limit its market demand. First, the market for high-speed data communications on the move is very narrow, as most data communications services (e-mail, SMS, stocks, etc.) are fully implemented with current narrowband mobile communications.
