ANETNNA GAIN IMPROVE PERFORMANCE

             ANTENNA GAIN FOR EXTERNAL ACCESS POINT 1562E and 1572EAC

ABOVE TWO PORTs are 5Ghz Single mode 

BELOW TWO PORTs are Dual mode and single mode for 2.4Ghz 

from Access point  CLI we are unable to find the Antenna model , Cisco Prime can provide Antenna model information.

ANTENNA GAIN = 2 x 0.5 dBi   

ACCESS POINT MODEL FOCUS :
