1.2.4 External GPS PPS Option
The External GPS Precise Positioning Service (PPS) option allows for
an external GPS device to provide the PPS input to the Mercury. This is
useful in installations where multiple radios require GPS timing. This
option prevents each Mercury from requiring its own GPS antenna.
Refer to the electrical specifications in the
External GPS PPS Option
section on Page 180. This option is only available in hardware revision
1.0.2 or later.
1.3 APPLICATIONS
The following sections provide illustrations of typical transceiver instal-
lations. This is an overview only. A Network Administrator should be
involved in all installation planning activities.
1.3.1 Mobile/Fixed Data System
Mercury transceivers support high-speed data communications in a
mobile environment. In this application, Remote radios “roam” between
different Access Points, providing seamless transitions and continuous
coverage throughout a municipal area.
Figure 1-4 shows an example of
an integrated system employing both mobile and fixed Mercury trans-
ceivers.
NOTE: 3650 MHz is for APs and Fixed Remote stations only.
