Many wireless communication systems employ code division multiple access (CDMA)technology, most notably 3rd generation cellular. Unfortunately, these systems are not able to meet the demand for wireless services in some markets and new techniques are being developed to improve the amount of data that can be simultaneously transmitted by multiple users over the limited available frequency spectrum. Many 4th generation proposals call for a completely new technology to be used. Such a solution requires replacing much of the existing wireless infrastructure.

许多无线通信系统采用码分多址（CDMA）技术，最显著的是第三代蜂窝。不幸的是，这些系统不能满足某些市场对无线服务的需求，目前正在开发新技术，以提高在有限的可用频谱上多个用户可以同时传输的数据量。许多第四代提案要求使用一种全新的技术。这样的解决方案需要替换大部分现有的无线基础设施。
