GUIDE

CORRECT SOLUTIONS.

2.4 GHz wavelength - correct answer- longer wavelengths, better range

larger channel widths - correct answer- provide faster speed and throughput but can create greater interference

• GHz wavelength - correct answer- supports faster data rates

at shorter distances, suited for high density deployments because of greater number of channels that do not overlap

What channel widths do 2.4 GHz support? - correct answer- 20 and 40 MHz

What channel widths do 5 GHz support? - correct answer- 20, 40, 80, 160 MHz

omnidirectional antenna - correct answer- Can transmit and receive with 360-degree coverage

directional antenna - correct answer- directs signals where the antenna oints

Beamforming - correct answer- technology that enables wireless devices with omnidirectional antennas to detect location of other wireless devices and direct a stronger signal in the direction of the devices

Antenna Gain - correct answer- The increase in signal strength by the concentration of radio waves by means of directional propagation.

ad hoc network - correct answer- wireless network where stations can communicate directly to each other

infrastructure network - correct answer- wireless clients must connect through a central wireless point that controls access to the wireless and wired networks
