How to Define on the Basis of Pilot Power Microcell or Repeater

Solution to Define on the Basis of Pilot Power Microcell or Repeater, cpich power use for 3g, repeater use in 3g and pilot power definition for wcdma network.

In particular, for application indoors, it is often desirable to predict the service area of ​​a repeater or microelement based power CPICH. In the repeater installation and commissioning, CPICH power can be determined by measuring the output (or input) Ec / No and the received signal. The objective is to estimate the range of the repeater, or equivalently, microelement Given the known pilot power in dBm. Although this method can be applied to any source of WCDMA, this applies particularly to the installation of repeater list as amplification repeater can be configured with the necessary amount of power;

However, between the individual powers, the channel can not be adjusted as it is possible for the picocell. Relative channel power is determined by the donor cell. The only signal held on a regular donor cell is CPICH power. If the repeater can be predicted on the basis of CPICH power emanating from the repeater, the repeater gain setting to be more accurate than attempting to predict coating based on a composite power WCDMA.

Inputs for the basic equation are no minimum required CPICH Ec / No to the EU and pricing, or assumptions, on the other-cell interference component that the EU experience at the cell edge. The output of this equation is the maximum transmission loss that can be maintained between the internal source (repeater or pico cells) and the EU.
