There is currently a great deal of interest in the use of unlicensed frequency bands for cellular system services. The state of the art standard for cellular system transmission is known as LTE. As a result this new system is commonly referred to as LTE-U. The push for LTE-U is motivated by the great success of cellular services based on smart-phones and the associated shortage of spectrum for cellular systems, and the fact that there is a large amount of spectrum that has been allocated to WiFi services, especially in the 5 GHz band. However the WiFi community is concerned that the "incursion" of LTE systems into the WiFi unlicensed bands will result in degradation of the quality of WiFi based services. The purpose of this project is to determine the impact of the addition of these LTE-U services on the WiFi services. The project will introduce various parameters to model the behaviour of LTE-U transmissions in the WiFi band and at the same time determine the impact on the WiFi services.

当前，对于蜂窝系统服务使用未授权频带存在很大的兴趣。用于蜂窝系统传输的现有技术标准被称为LTE。因此，这种新系统通常被称为LTE-U。推动LTE-U的动机是基于智能手机的蜂窝服务的巨大成功和蜂窝系统的频谱的相关短缺，以及存在大量频谱被分配给WiFi服务的事实，特别是在5GHz频带中。然而，WiFi社区担心LTE系统“侵入”WiFi未授权频带将导致基于WiFi的服务的质量下降。该项目的目的是确定增加这些LTE-U服务对WiFi服务的影响。该项目将引入各种参数来模拟WiFi频段中LTE-U传输的行为，同时确定对WiFi服务的影响。
