因特网的迅猛增长已广为人知,但较少人知道的是,无线电话,尤其是无线因特网的用量也以空前的速率增长着。预计到2002年底,无线语音用户将超过有线(传统电话)用户。更令人惊奇的是,无线因特网接入用户量同时将超出有线因特网(通过计算机)接入用户量。这种预测的根据是:多数手机在不久的将来会具备因特网的接入能力。有三个关键因素影响着无线因特网接入潜能的充分展现。一是无线数据传输率要和目前有线因特网数据率大致相当,二是无线传输总容量要和目前有线因特网数据容量大 The rapid growth of the Internet is well known, but less often people know that the usage of wireless phones, especially the wireless Internet, has also grown at an unprecedented rate. It is estimated that wireless voice users will surpass wired (traditional phone) users by the end of 2002. Even more surprising is that the amount of wireless Internet access users will simultaneously exceed the wired Internet (through the computer) access to the user volume. The basis for such a prediction is that most handsets will have Internet access in the near future. Three key factors affect the full potential of wireless Internet access. First, the wireless data transmission rate and the current wired Internet data rate roughly the same, and second, the total wireless transmission capacity and the current wired Internet data capacity
