Wireless communication systems are an integral part of modern society. On a national scale, the wireless industry contributes $23.5 billion to the gross domestic product, $2.7 billion in investments, and 134,100 jobs. On an international scale, the wireless industry generates nearly 4% of the global gross domestic product, with $3.8 trillion in contributions spanning 236 countries. However, there is a looming challenge for the existing wireless technologies. Contemporary wireless systems have relied upon radio-frequency technology, with carrier frequencies spanning 3 kHz to 300 GHz, but the demand for radio-frequency systems has doubled every 18 months. We are now witnessing capacity limitations due to the limited number of licensed radio-frequency bands. Spectrum scarcity is a serious concern for the industry.

无线通信系统是现代社会的组成部分。在全国范围内，无线产业为国内生产总值贡献了235亿美元，投资27亿美元，创造了134，100个就业机会。在国际范围内，无线产业占全球国内生产总值的近4%，贡献了3.8万亿美元，遍布236个国家。然而，现有的无线技术面临着一个迫在眉睫的挑战。现代无线系统依赖于射频技术，载波频率从3 kHz到300 GHz，但对射频系统的需求每18个月翻一番。由于许可的无线电频段数量有限，我们现在看到容量有限。频谱稀缺是该行业的一个严重问题。
