LoRa Transceivers

 

BALN-LR

 
 

The self-developed BALN-LR20 is a half-duplex next-generation wireless communication transmitter/receiver using standard RS232/485 connectors and communication protocols. It is equipped with LoRa (Long-Range) function that supports TX & RX modems, supports Transparent Transmisson mode, and uses DC 8~28V power.

Communication frequency band: 900~931MHz (default setting: 923MHz)

BALN-LR20 has the advantage of being able to communicate wider, farther, and without data loss from the wireless transmitter through the anti-jamming and cross-talk prevention characteristics by applying the direct sequence type communication technology. Easier coding and correction are possible through the FEC algorithm of the self-developed wireless transmitter software (BALN-LRs) tool. It has the advantage of being convenient because it is easy to respond to changes in the on-site situation because it can be expanded at any time, even in case of reduction of construction cost, reduction of various labor costs, test operation, and additional expansion of equipment.

 
 
 

BALN-LR Characteristics

  • Use of SEMTECH SX1276 main chipset with proven high reliability

SPECIFICATION

 

What is LoRa?

 

LoRa is an abbreviation of Long Range, which is a combination of Lo of Long and Ra of Range. As the Internet of Things developed, it was thought that it would be difficult to apply the existing communication equipment to the IoT field.

LoRa is characterized by security, low power, and high-efficiency long-distance communication.

 
 
 
 

Introduction effect

  • Depending on the site conditions, wireless transmission and reception control is possible where it is unavoidable to apply wired communication construction, so construction costs are reduced, labor costs are minimized, and test operation is shortened.

  • Reducing infrastructure cost Reducing the cost of building IoT based on a unified system

  • Fast automatic control of equipment even remotely by judging data reference information with fast equipment control firmware

  • Platform Linkage Expansion Effectively link with IoT and big data platforms through wired and wireless networks

  • It is convenient to integrate and manage data using wireless LoRa transmission and reception of dispersed buildings, and it is easy to respond to changes in the field situation.

  • BALN-LR20 product applicable to wireless LoRa transmission/reception communication with various equipment for measuring BAS, IBS, ZEB, BEMS and energy use data in buildings
