Cisco Cisco Aironet 1530i Outdoor Access Point 설치 가이드

For a radiated test bed, the following equation describes the relationships among transmit power, 
antenna gain, attenuation, and receiver sensitivity:

txpwr + tx antenna gain + rx ant gain - [attenuation due to antenna spacing] < max rx 

input level

Where:

txpwr = Radio transmit power level

tx gain = transmitter antenna gain

rx gain = receiver antenna gain

For a conducted test bed, the following equation describes the relationships among transmit power, 
antenna gain, and receiver sensitivity:

txpwr - [attenuation due to coaxial RF Attenuator components] < max rx input level 

(0 dbm)

Under no circumstances should you connect the antenna port from one access point to the 
antenna port of another access point without using an RF attenuator. If you connect 
antenna ports you must not exceed the maximum survivable receive level of 0 dBm. Never 
exceed 0 dBm or damage to the access point can occur. Using attenuators, combiners, and 
splitters having a total of at least 60 dB of attenuation ensures that the receiver is not 
damaged and PER performance is not degraded.

Read the installation instructions before connecting the system to the power source. 
Statement 1004

Before you begin the installation process:

Become familiar with the procedures for mounting the access point (see the 

Become familiar with the access point connections (

, and 

).

Verify that the switch you are using to connect the controller is configured properly.
