通过Wi-Fi LTE集成增强容量和覆盖范围

Enhanced capacity & coverage by Wi-Fi LTE Integration

Jonathan Ling, Satish Kanugovi, Subramanian Vasudevan, A Krishna Pramod

摘要:

Wi-Fi结合宽带蜂窝网络在热点处提供具有成本效益的数据容量。热点需要捕获大量用户并提供高数据率。Wi-Fi接口上的数据率受介质访问协议的影响,当大量用户处于活动状态时,介质访问协议会由于延迟和意外冲突而损失吞吐量。决定可以关联的用户数量的热点范围受到客户端而不是接入点的较低功率的限制。通过经由另一接入网络转移去往接入点的业务,可以提高范围和效率。该上行链路重定向或转向通过同时使用Wi-Fi和LTE无线电接口来实现。三个选项-松散,紧密和混合集成,以提供增强的容量和覆盖范围。

英文摘要:

Wi-Fi provides cost-effective data capacity at hotspots in conjunction with broadband cellular networks. The hotspots are required to capture a large number of users and provide high data rates. Data rates, over the Wi-Fi interface, are influenced by the media access protocol, which loses throughput due to delays and unintended collisions when a large number of users are active. The hotspot range which determines the number of users, that can associate, is limited by the lower power of the client rather than the access point. By diverting the traffic destined to the access point via another access network, both range and efficiency can be improved. This uplink redirection or diversion is achieved by simultaneous use of the Wi-Fi and LTE radio interfaces. Three options - loose, tight, and hybrid integration are presented towards providing enhanced capacity and coverage.
