Transmission Power Optimization in Live 3GPP LTE-A Indoor Deployment

As demand for mobile broadband grows, the need for greater indoor coverage and capacity becomes more urgent as the ubiquitous connection to the Internet is mentioned very often. Complementing macro capacity, small cells (femto-, pico-cells) offer a cost-effective way to meet this demand for complex indoor areas. Inspired by this increasing demand, we provide in this paper a comprehensive summary on our live trial of transmission power optimization within the full-featured 3GPP LTE-A indoor deployment. To deliver a comprehensive view on the configuration of TX power, we perform an evaluation between our previous results provided by our implemented PyLTEs software and our optimized configuration. In order to deliver a complete picture, the obtained data from simulator is complemented with the real measurement in LTE-A indoor deployment. Our findings show that performed changes lead to improved of all measured networks parameters as latency, RSRP, RSRQ, and RSSI. On top of this, the discussed changes are not bonded with the particular LTE deployment - therefore, the utilization is not restricted and can be implemented in various indoor LTE deployments.
