Just as cellular phones have become as popular as land lines, wireless Internet is on the verge of competing with traditional wire-based Internet. With the rapid spread of wireless availability, it is only a matter of time before finding an Internet signal will be as easy as finding a signal for one's cell phone. The future is definitely now for UW-Madison. Engineers on campus are working on a new system called the 21st Century Network, which aims to add wireless capabilities to each campus building by the summer of 2006. Wi-Fi, short for "wireless fidelity," is the system that handles wireless networking. Similar to walkie-talkies, Wi-Fi uses radio signals to send and receive information through the air. The signals are broadcasted from an access point hardwired (physically connected) to a network and travel to any devices that can read the signal.

机译：就像手机已经像固定电话一样流行一样，无线互联网也即将与传统的有线互联网竞争。随着无线可用性的迅速普及，找到互联网信号就像找到手机信号一样容易，只是时间问题。威斯康星大学麦迪逊分校的未来绝对是现在。校园的工程师正在开发一种名为21st Century Network的新系统，该系统旨在在2006年夏季之前为每个校园建筑物增加无线功能。Wi-Fi是“无线保真”的缩写，是处理无线网络的系统。与对讲机类似，Wi-Fi使用无线电信号通过空中发送和接收信息。信号从硬连接（物理连接）的接入点广播到网络，然后传播到可以读取该信号的任何设备。
