Benefits of technology

This patented technical effect allows users on different types of wireless devices (such as mobile phones) within their home/office premises to access services from more than just one type of service provider without having to switch between them if they want to receive data wirelessly over several hours instead of once per day. By doing this, these connections become even better because there're no interruptions during peak times.

Problems solved by technology

This patents describes two technical ways that aim at enhancing wireless local area networking performance without sacrificing its own strength. Firstly, it suggests adding directionality into certain directions within specific regions where radio wave propagation may degrade their effectiveness. Secondly, introduces a new type called polarized double-wave technology - specifically targeted towards improved reception capabilities on mobile devices like smartphones. These techniques help enhance both upstream and downlinings of communications while reducing energy consumption.

Abstract

The embodiment of the invention provides an indoor multisystem-shared uplink and downlink signal processing method and a device for the same. In an indoor distributed system shared by multiple communication networks, at least multiple indoor antennae jointly covering the frequency range of the uplink signals are selected, the uplink signals received by the selected multiple indoor antennae in a diversity reception manner are combined into one path of uplink signal; when a base station needs to transmit the downlink signals, an antenna subset with better coverage quality is selected for performing downlink coverage according to the position of a terminal, or the amplitudes of the downlink signals of different ports are weighted, and the offset of the antenna horizontal beam after weighting is used for enhancing the downlink coverage of the needed direction. The quality of the uplink signals received by each communication network is enhanced, and the transmission quality of the downlink signals is improved.
