Why does a wireless MAN offer good return on investment?
Answer: Wireless MANs eliminate the need to install expensive cabling or lease communications circuits.
A learning bridge forwards all packets. True or false?
What is the primary difference between a bridge and an access point?
Answer: A bridge connects networks together. An access point connects end users.
What are examples of semidirectional antennae?
Answer: Patch and Yagi.
In regards to beamwidth, what is the primary difference between a semidirectional and highly directional antenna?
Answer: A highly directional antenna has a much narrower beamwidth, which increases range if the power remains constant.
What is an example of a highly directional antenna?
Answer: Dish antenna.
What polarization would be most effective at a receiver if the transmitter were using vertical polarization?
Answer: Vertical polarization.
What are the advantages of using point-to-multipoint systems versus point-to-point for interconnecting multiple sites?
Answer: Point-to-multipoint can be less expensive and easier to add more sites.
What are the advantages of using packet radio for wireless MANs?
Answer: Packet radio routers don't require any cabling between them, and the system is relatively survivable because packets can take a different route if a router becomes inoperative.
Which standards do wireless MANs employ?
Answer: 802.11, Wi-Fi, and 802.16.
