3.7.2.4 GPS Status
A more detailed overview of the internal GPS module's state can be obtained, which displays the radio's altitude,
GPS-recovered time, and lots of information about the satellites in view of the GPS antenna.
The radio can be configured to send an SNMP trap if the number of GPS Satellites in view is low, or if the number
of GPS satellites in view has been low for 12 hours. Both of these traps could indicate a problem with the GPS
antenna configuration.
3.8 WIRELESS INTERFACE
The radio has one wireless interface that consists of two RF ports. This section describes the information and
configuration options available for the wireless interface. See
Figure 3-8 , Figure 3-9 , Figure 3-10 , Figure 3-11 .
3.8.1 System Mode
The radio can operate in multiple system modes under two configuration types. Refer to Paragraph 2.1.3 for more
information about the configuration types.
3.8.1.1 SPMP and SPTP
Simple Point to Multiple Points (SPMP) and Simple Point to Point (SPTP) provide simple setup and configuration.
The central radio in a SPMP system, or Sector Controller (SC), is responsible for transmitting management, timing,
and provisioning information to all configured radios within a sector. It controls the list of radio links and
periodically transmits a beacon that allows new radios in the sector to link up. The Subscriber Station (SS) is one of
the edge nodes in a SPMP system. The SS is responsible for feeding back information about the quality of the radio
link to the SC, which allows the SC to optimize transmissions.
3.8.2 Radio Mode
The radio has two RF ports, which can be used either together or individually. The RF ports can also be turned off,
for maintenance or troubleshooting.
3.8.3 Transmit Power
The transmit power settings are described below.
3.8.3.1 Maximum
The maximum transmit power applies to both RF ports. This is used to limit the transmit power for Effective
Isotropic Radiated Power (EIRP) or co-channel interference reasons.
Even though the Transmit Power may be set to a particular value, the radio will not necessarily operate at that level.
There are a few factors which dictate what actual Transmit Power will be used for a particular transmission burst:
radio type, current RF Frequency, and current Burst Rate (not supported in software version 3). Refer to
Table 3-4
and Table 3-5 for details regarding the Transmit Power behavior of radio type T502C and T503A, respectively.
Refer to Table 3-6 for Burst Rates.
