on each antenna that are occupied by beltpacks. This information may be useful
during a site survey, or when troubleshooting coverage areas or antenna
connections.
A typical display is shown below:
Figure 3: ANTNS menu
The numbers 1 through 10 represent the maximum number of antennas that can
be connected to the base station. Numbers 1 through 5 can be positions on a
splitter connected to transceiver port 1, while 6 through 10 can be positions on a
splitter connected to transceiver port 2. An antenna connected directly to
transceiver port 2 would appear at position 6.
“__” indicates an empty slot on an acive antenna that is connected to the base
station. A number in place of a “__” indicates that this slot is occupied by the
indicated beltpack.
Blank spaces next to an antenna number indicate that no antenna has been
detected in this position.
So the above display would indicate that five antennas are connected to the base
station in positions 1, 2, 3, 6, and 7. There are no active antennas in positions 4,
5, 8, 9, and 10.
There are 4 beltpacks currently connected. Beltpacks 2 and 4 occupy the first 2
slots of antenna 3; beltpack 1 occupies the first slot of antenna 6; and beltpack 3
occupies the first slot of antenna 7.
The display updates every 4 seconds to reflect changes in antenna status and
beltpack connections.
Rotate or push in the setup/enter knob to exit this menu.
ASSIGNING BELTPACKS TO COVERAGE AREAS
Each antenna is designed to handle five beltpacks simultaneously. Although it
can achieve this in good conditions, this may not always be possible for a number
of reasons. First, interference or propagation problems may mean that not all
antenna slots are available all the time. Second, a beltpack constantly searches for
the best antenna signal, and may frequently switch antennas. To make this
transmission seamless, a beltpack maintains the connection to its current antenna
until it is confident that the new antenna is functioning well. Therefore, for a
short period of time during this transition, a single beltpack can occupy slots on
more than one antenna.
This means that for zones in which you are likely to need coverage for five or
more beltpacks simultaneously, it is recommended that you install a second
