The ever-growing consumption of data by mobile device users is placing a strain on mobile networks, and as a result, system operators are continually making upgrades to their wireless wide area networks. With the increasing number of WiFi capable mobile devices and WiFi access becoming ubiquitous in homes, enterprises and retail locations, WiFi offload is an attractive option for network operators. While mobile cellular service providers are expecting mobile data traffic to increase by 11-fold over 2013-2018, mobile data is costly to provide, and in 2013, 45 percent of global mobile data traffic was offloaded. The emerging IEEE 802.11ac WiFi standard contains enhancements for better physical-layer support for multiple antennas via multi-input multi-output (MIMO) technology to enable, for example, wireless local area network (WLAN) access points (APs) to transmit packets simultaneously to multiple users at high rates. Not only does 802.11ac support multi-user MIMO, there are also potential media access (MAC) network protocol efficiency improvements possible through both frame aggregation and multipath transmission control protocols (TCP).

移动终端用户对数据的不断增长的消费给移动的网络带来了压力，并且因此，系统运营商不断地对其无线广域网进行升级。随着支持WiFi的移动的设备数量的增加以及WiFi接入在家庭、企业和零售场所变得无处不在，WiFi卸载对于网络运营商来说是有吸引力的选择。虽然移动的蜂窝服务提供商预计移动的数据流量将在2013-2018年期间增长11倍，但提供移动的数据的成本很高，2013年全球移动的数据流量中有45%被卸载。 新兴的IEEE 802.11ac WiFi标准包含用于经由多输入多输出（MIMO）技术对多个天线的更好的物理层支持的增强，以使得例如无线局域网（WLAN）接入点（AP）能够以高速率同时向多个用户发送分组。802.11ac不仅支持多用户MIMO，还可以通过帧聚合和多路径传输控制协议（TCP）来提高媒体接入（MAC）网络协议的效率。
