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 iscommonly referred to as LTE-U. The push for LTE-U is motivated by the great success of cellular servicesbased on smart-phones and the associated shortage of spectrum for cellular systems, and the fact that there is alarge amount of spectrum that has been allocated to WiFi services, especially in the 5 GHz band. However theWiFi community is concerned that the "incursion" of LTE systems into the WiFi unlicensed bands will result indegradation of the quality of WiFi based services. The purpose of this project is to determine the impact of theaddition of these LTE-U services on the WiFi services. The project will introduce various parameters to modelthe behaviour of LTE-U transmissions in the WiFi band and at the same time determine the impact on the WiFiservices.

目前，人们对使用未经许可的频段进行蜂窝系统服务非常感兴趣。蜂窝系统传输的最新标准称为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以及蜂窝系统相关的频谱短缺，以及已经分配给WiFi服务的大量频谱，特别是在5 GHz频段。然而，WiFi社区担心，LTE系统“侵入”WiFi未经许可的频段将导致基于WiFi的服务质量下降。本项目的目的是确定这些LTE-U服务的增加对WiFi服务的影响。该项目将引入各种参数来对WiFi频段中LTE-U传输的行为进行建模，同时确定对WiFi服务的影响。
