Wireless system signal propagation collection and analysis

摘要: Wireless systems coverage planning uses propagation modeling to provide a prediction of service coverage. Accurate and effective wireless analysis requires measurement signal strength knowledge the location corresponding measurement. strength, RSSI, can determined by measuring received mobile unit from cell site antenna or be unit. The is compared origination determine path loss, RSSI. number different methods. handset-based network-based. Examples include enhanced global positioning systems; observed time difference; estimated departure. network-based arrival; difference power level; angle arrival. Each these methods rely on travel cellular between at least one site. are utilized develop set data used evaluate effectiveness system. In addition, measurements facilitate determination likely areas, scoring based upon traffic patterns correction system anomalies.
