JAVAD HPT404BT 4W UHF Radio Transceiver
The HPT404BT 4W UHF radio transceiver from JAVAD GNSS provides a high-speed point-to-point and point-to-multipoint wireless data transfer at up to 38.4 kbps, at a maximum range of 16 miles (26 km).
Description
Overview
The HPT404BT 4W UHF radio transceiver from JAVAD GNSS provides a high-speed point-to-point and point-to-multipoint wireless data transfer at up to 38.4 kbps, offers USB/Bluetooth® capabilities, and an optional built-in quad band GSM/GPRS module.
The HPT404BT accesses VRS network using via GPRS, takes incoming data from the network, modulates it with GMSK, FSK, PSK or most spectrum efficient QAM modulation and transmits it at RF power output levels from 15 dBm up to 36 dBm operating in UHF frequency band (406 to 470 MHz).
The HPT404BT is also capable of receiving RF signal from remote UHF transmitter, and the data could be send over the cellular network using built-in GSM/GPRS module if such operation mode is selected.
The HPT404BT firmware 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 16 miles/26 km). It also includes a selectable error correction, which improves the functioning of the radio modem under interference.
The sophisticated features of the HPT404BT include data scrambling, frequency hopping, user selectable transmit output power level, low power consumption sleep modes, autoscanning for base 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 HPT404BT radio modem resides in a flash memory. The updating of the radio modem programs is entirely software-based. The flash memory is re-programmable through an RS-232 interface, USB, Bluetooth, or over the air.
