XYZ Corporation is experiencing connectivity problems with their existing building-to-building bridge link. A concrete wall on the roof of one building is partially blocking the Fresnel Zone, and the connection is dropping many frames.
The administrator moves the antenna to an area not obstructed by the concrete wall and then realizes the RF cable cannot reach the new location.
If an extension cable is added to move the antenna, what are the likely results?
- A . The data throughput rate will increase because VSWR will decrease.
- B . The Equivalent Isotropically Radiated Power (EIRP) will decrease.
- C . The antenna’s azimuth beamwidth will decrease.
- D . The size of the Fresnel zone will increase.
- E . The likelihood of a direct lightning strike will increase.
Which modulation types are used by OFDM technology? (Choose all that apply.)
- A . QAM
- B . Phase

- B . Verify the solution
- C . Notify the users of problem resolution
- D . Document the results
___________ uses more bandwidth than is necessary to carry its data.
- A . Narrowband
- B . Spread Spectrum
- C . Multipath Interference
- D . Frequency Hopping
Which one of the following channels can be used for VHT transmissions according to the 802.11 specification?
