A customer in Europe needs to establish an 11-Mbps wireless bridge link between two office buildings that are approximately 1.3 km apart. The wireless link will pass through a
public park, which contains a lake that is surrounded by trees. You run the range calculation and determine that the Cisco Aironet 1300 Series Outdoor Access Point/Bridge should work. You install the link using 10.5-dB yagis with 75 feet of standard Cisco cabling and both radios set at 20 mW. The wireless bridges are not able to establish or maintain a link.
What is needed to successfully complete this link?
A.
An amplifier needs to be installed at one of the sites.
B.
The antenna must be raised high enough to clear the trees.
C.
Lower loss cabling needs to be used to bring the EIRP into legal limits.
D.
Due to the trees, a 21-dBi dish needs to be used for its narrower beamwidth.
