Figure
shows an example
of a distribution center (DC). The DC stores perishable items. Different areas
of the DC are kept at different temperatures. Some of the areas are freezers
with temperatures as low as -29 degrees C (-20 degrees F). Installing APs in
areas with temperatures this low may require expensive heated enclosures to
protect the APs. An alternative may be to use an antenna splitter. By using a
splitter, the AP can be mounted outside the freezer with one antenna providing
an area of coverage outside the freezer and the other antenna providing
coverage inside the freezer. Beyond the savings of not having to buy the
expensive heated enclosure, the customer does not have to pay for the extensive
time it would take to install cable and power inside the freezer. Installing
this type of equipment while wearing a subzero suit and heavy gloves can take a
quite a bit of time and be very expensive.
Antenna
Diversity
While using antenna diversity the AP uses one antenna or the
other, but never both. Do not attempt to attach one antenna to each connector
and place one inside the freezer and the other outside the freezer. This would
not be an effective solution. In the examples of using antenna splitters shown
in Figure
, the
diversity antenna feature might be disabled. Otherwise, two splitters and four
antennas would be needed.
