OpenBTS: 2.8 Konfigurasi Cognitive Radio Elsabagh

Sumber: http://wush.net/svn/range/software/public/openbts/features/Cognitive_Radio_Elsabagh/apps/OpenBTS.config.example

# Sample OpenBTS configuration file.

# Formatting rules:

# Configuration values are defined with line of the form <key><space><value>
# The key name can contain no spaces.
# Everything between the first space and the end of the line becomes the value.
# Numeric values can be preceded with "0x" for hex.

# Blank lines are OK.

# Lines starting with "#" are comments.

# By default, configuration values can be changed but not removed after initialization.

# Lines starting with "$" are directives that define other properties of config values:
# "static" --  configuration value cannot be changed or removed after initialization.
# "optional" -- configuration value may be removed after initialization.

# As a gerenal rule, non-valid configuration values will crash OpenBTS.
# So be cafeful.

# Downlink adaptive power management.

# So the output power, in dBm, is Po = 20 + 40 - 10 - Atten = 50 - Atten.
# So Atten = 50 - Po.
# That has been verified on the CMD57.
# HPA-900 max ouput is 42 dBm: Atten = 50 - 42 = 8 dB.
