Answers to Review Questions
1. A, B, D. The goal of fxed mobile convergence is to enable the user to have a single device
with a single telephone number and to enable the user to roam between different networks,
taking advantage of the least expensive network that is available.
2. C, D. Municipal and transportation networks are both specifc types of public hotspots.
enforcement and frst
responder networks are hotspot
type networks, but they are not
for public use.
3. C. Because of the potential for interference and the importance of preventing it, hospitals
often have a person responsible for keeping track of frequencies used within the organization.
Some municipalities are starting to do this as
not just for law enforcement, but for all
of their wireless needs, because they often use wireless technologies for SCADA networks,
traffc cameras, traffc lights, two
way radios, point to point bridging, hotspots, and more.
4. D. Since cruise ships
are often not near land where cellular or WiMAX uplink is available,
it is necessary to use a satellite uplink to connect the ship to the Internet.
5. B, D. Fixed mobile convergence allows roaming between Wi
Fi networks and cellular
networks, choosing the available network that is least expensive.
6. D. When designing a warehouse network, the networking devices are often barcode scanners
that do not capture much data, so high capacity and throughput are not typically needed.
e the data
transfer requirements are so low, these networks are typically designed to
provide coverage for large areas. Security is always a concern; however, it is not usually a
7. A, D. Corporations typically install a WLAN to provide
easy mobility and/or access to
areas that are diffcult or extremely expensive to connect via wired networks. Although
providing connectivity to the Internet is a service that the corporate wireless network
offers, it is not the driving reason for instal
ling the wireless network.
8. A, C, D. The telephone company, cable providers, and WISPs are all examples of companies
that provide last
mile services to users and businesses.
9. B. The main purpose of SOHO networks is to provide a gateway to the Internet
10. A, B, D. Mobile offce networking solutions are temporary solutions that include all of the
options listed except for the remote sales offce, which would more likely be classifed as a
11. A, D. Warehousing and manufacturing envir
onments typically have a need for mobility, but
their data transfers are typically very small. Therefore, their networks are often designed for
high coverage rather than high capacity.
12. D. Hotspot providers are not likely to provide data encryption. I
t is more diffcult to
deploy, and there is no beneft or business reason for them to provide it.
13. A, B, C. Manufacturing plants are typically fxed environments and are better served by
installing permanent access points.
14. B, C, D. Point
t, hub and spoke, and star all describe the same communication
technology, which connects multiple devices by using a central device. Point
munications connects two devices.
15. C. Most of the 802.11 implementations used FHSS, with industrial (warehousing and
manufacturing) companies being some of the biggest implementers. Their requirement of
mobility with low data
transfer speeds was ideal for using the technology.
To make wireless access easy for the subscriber, hotspot vendors typically deploy authen
tication methods that are easy to use but that do not provide data encryption. Therefore, to
ensure security back to your corporate network, the use of an IPSec VPN
17. A, C, D. VoWiFi is a common use of 802.11 technology in a medical environment, providing
immediate access to personnel no matter where they are in the hospital. Real
system (RTLS) solutions using 802.11 RFID tags for inven
tory control are also commonplace.
WLAN medical carts are used to monitor patient information and vital signs.
18. A, C. The installation of multiple point
point bridges is either to provide higher through
put or to prevent a single point of failure.
Care must be taken in arranging channel and
antenna installations to prevent self
19. A, B, C. Healthcare providers often have many other devices that use RF communications,
and therefore, RF interference is a concern. Fast access
along with secure and accurate access
is critical in healthcare environments. Faster access can be performed without faster speed.
The mobility of the technology will satisfy the faster access that is typically needed.
20. A. Public hotspots are most con
cerned about ensuring that only valid users are allowed
access to the hotspot. This is performed using authentication.
