CDMA450 indoor coverage enhancement

This paper intends to share the deployment experience of CDMA450 repeater for a distinctive indoor structure. Firstly, the CDMA450 technology is introduced, in particular the coverage advantage. Even so, CDMA450 operators have to deal with shadowed and dead spots in network planning. Hence, the importance of repeaters in solving the issues regarding the coverage hole with minimum cost is presented. This paper also reviews the repeater design for CDMA450 application which later, a real deployment case is presented to show the potential of the prototype. From the field test results, the in-house developed repeater has shown reliable performance for indoor coverage enhancement of a convention center by improving the E_c/I₀.
