Paging Success Ratio, IRAT Failure, CPICH power

Iklann lewatttt...sepintas sore ini

 Paging Success Ratio:
adalah respons paging ke attempt paging (banyaknya percobaan paging) dalam jaringan WCDMA UMTS.
Nilai yang baiknya adalah di atas 90%.

  IRAT Failure :
IRAT = Inter Radio Access Technology
Ada beberapa penyebab untuk kegagalan IRAT / IRAT Failure di jaringan seluler.
4 Penyebab utamanya adalah :

1. Missing relation ke 2G
2. Tidak adanya 2G resources
3. Poor 2G Coverage
4. Missing relation ke 3G

Tambahan dari telecomfunda nih:

What is a typical CPICH power?

CPICH power typically takes about 10% of the total NodeB power.  For a 20W (43dBm) NodeB, CPICH is around 2W (33dBm).
In urban areas where in-building coverage is taken care of by in-building installations, the CPICH may sometimes go as low as 5% because:
  • The coverage area is small since users are close to the site, and
  • More power can be allocated to traffic channels.
