Access Points
It is a good idea to carry more than one access
point. Many engineers have had a mishap with an AP resulting in wasted time
during the survey. An extra AP allows the survey to continue without having to
wait for a spare to be shipped.
APs can have a variety of
configurations, as listed in Figure
. Access points
that have Reverse Polarity Threaded Naval Connectors (RP-TNC) give the site
survey engineer the option of using a variety of antennas to overcome coverage
problems. Different antennas may have different types of connectors, as shown
in Figure
. The
1200 Series AP 2.4-GHz antenna ports have RP-TNC connectors. The 1100 Series AP
does not have RP-TNC connectors, which limits the site survey engineer to a
diversity 2.2 dBi antenna. The 1200 Series AP has a 5-GHz module that serves as
the 5-GHz CardBus radio and the antenna. Due to FCC requirements the 5-GHz
antenna module offers two options, which are 6 dBi patch mode and 5 dBi omni
directional mode.
Client Cards
There are multiple types of
PCMCIA cards, as shown in Figure
. A
survey kit should contain at least one of each type of PCMCIA card. Survey the
site with the type of card that will most likely be used.
