In indoor Light Fidelity (Li-Fi) system the position of transmitter and receiver bring different impact on coverage area. Due to Line of sight (LOS) characteristics of Li-Fi, coverage area of a light emitting diode (LED) transmitter plays a vital role for efficient reception of data. In this paper we considered the case when 1 optical receiver can simultaneously receive signal of 2 LED transmitters and present an optimal solution of controlling coverage area of LED transmitter using dimming factor. This paper focuses on efficient reception of data by controlling coverage area of multiple LED transmitters. The performance of proposed dimming factor approach is evaluated by using different dimming based modulation schemes.
