Overview
The HPT435BT JL 35W 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, and offers USB, Ethernet and Wi-Fi/Bluetooth® capabilities.
The HPT435BT JL 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 48 miles/77 km). It also includes a selectable error correction, which improves the functioning of the radio modem under interference.
The sophisticated features of the HPT435BT JL include data scrambling, frequency hopping, user selectable transmit output power level, low power consumption sleep modes, auto-scanning for a base and plug-and-play installation for remote terminals.
The HPT435BT JL could be a part of a local/global network connected to the Internet via WiFi, Ethernet, Bluetooth, or 4G cellular module (optional). It provides a robust solution linking the field GNSS equipment to RTN, where no cell phone cover is available. The HPT435BT JL can be configured and supported using web-interface through the Internet, and this makes the setup mechanism simple and accessible from anywhere in the world.
