Introduction
External extra rugged digital high power UHF radio transceiver program-
mable in frequency ranges from 406 to 470 MHz. It has GMSK, DBPSK,
DQPSK, 4FSK, D8PSK, and D16QAM modulations with advanced for-
ward error correction and data scrambling. The output power is program-
mable from 320 mW to 35 W.
Figure 1. HPT435BT
The HPT435BT radio transceiver provides a high-speed Point-to-Point and
Point-to-Multipoint wireless data transfer at up to 38.4 kbps. HPT435BT
supports user selectable modulation techniques (GMSK, 4FSK, DBPSK,
DQPSK, D8PSK, or D16QAM), which allows the user to achieve the
highest data speed for a given range (up to 48 miles / 77 km). It also in-
cludes a selectable error correction, which improves the functioning of the
radio modem under interference.
The sophisticated features of HPT435BT include data scrambling, fre-
quency hopping, user selectable transmit output power level, low power
consumption sleep modes, autoscanning and plug-and-play installation for
remote terminals.
The built-in software tools provide the wireless link testing, unit's status
and error statistics monitoring as well as unit's settings change over the air.
The firmware of the HPT435BT radio transceiver resides in a flash memo-
ry. The updating of the radio modem programs is entirely software-based.
The flash memory is re-programmable through an RS232 interface, USB,
Bluetooth, or over the air. The unit's user settings can be changed through
8
the built-in Command Line interface (CLI), FieldCAD, Tracy Software or
through ModemVU.
