WiFi
Objectives:
From this self-study program you should learn:
- What
is WiFi and what standards are available
- How
WiFi provides connectivity indoors and outdoors
- What
is involved in designing WiFI networks
Introduction
No
network can probably be built without wireless
today. People want to be mobile. Practically
everybody uses a laptop as their primary computer,
excepting engineers or graphic designers at workstations,
and most of them will also have a laptop as a second
computer to carry, along with everybody else, on trips and
to meetings where everybody brings their laptops and
connects on WiFi.
Besides
laptops on WiFi, people use tablets and smartphones
for wireless communications. Smartphones allow web
browsing with connection over either the cellular network
or a WiFi network. Some mobile phones are portable VoIP
devices connecting over WiFi to make phone calls. While
WiFi has had some growing pains and continual upgrades,
the IEEE 802.11 standard it has become more reliable and
offers what seems to be adequate bandwidth for most users.
Outside
the office, or home for that matter, WiFi connections are
expected in many public spaces - coffee shops of course,
but also restaurants, hotels, convention centers, and
simply on the street. Inside the city, WiFi can used for
line-of-sight communications where fiber is too hard to
install or expensive. In rural areas where any means of
communications is expensive,
line-of-sight WiFi is often the least expensive
alternative.
In this lesson we'll look at the technology and
applications of WiFi.
