LoRaWAN
LoRaWAN
In today's rapidly digitizing world, IoT (Internet of Things) devices and applications are becoming increasingly prevalent. In this context, long-range wireless communication technologies play a significant role. One such technology that stands out is LoRa, which offers an innovative solution for low-power, long-range wireless communication.
MQTT
MQTT
As the Internet of Things (IoT) continues to grow, the demand for efficient, lightweight, and reliable communication protocols becomes essential. One of the most popular protocols meeting these demands is MQTT (Message Queuing Telemetry Transport).
Broadband Power Line (BPL)
Broadband Power Line (BPL)
Broadband Powerline Technology (BPL), also known as Powerline Communication (PLC), represents a revolutionary approach to data transmission, leveraging the existing electrical power infrastructure to deliver broadband internet connectivity.
Wireless MBus (WMBus)
Wireless MBus (WMBus)
In an era defined by connectivity and data-driven decision-making, the need for efficient and reliable metering solutions has never been greater. Enter Wireless M-Bus (Meter-Bus) technology, a versatile and robust platform designed to revolutionize remote meter reading and data communication in utility management systems.
IEC62056-21 (for Electricity Meters)
IEC62056-21 (for Electricity Meters)
IEC 62056-21 is an international standard for communication with electricity meters. Developed by the International Electrotechnical Commission (IEC), this protocol standardizes the way data is exchanged between meters and various devices or systems, ensuring interoperability and efficient data management.
P1 Companion Standard (for Electricity Meters)
P1 Companion Standard (for Electricity Meters)
Smart energy meters have become essential in monitoring and controlling energy usage. To facilitate better integration, communication, and functionality of these smart meters, standards are crucial. One such standard, particularly relevant in Europe, is the P1 Companion Standard.
Modbus RTU
Modbus RTU
Modbus RTU is a widely recognized and utilized communication protocol in the field of industrial automation. Developed by Modicon (now Schneider Electric) in 1979, it was designed to facilitate communication between various electronic devices, primarily programmable logic controllers (PLCs).
Modbus TCP
Modbus TCP
Modbus TCP, also known as Modbus TCP/IP, is a widely adopted communication protocol in the industrial automation sector. It was developed to enable Modbus communication over Ethernet networks, combining the reliability and simplicity of the Modbus protocol with the versatility of Ethernet.
LoRa RF Communication
LoRa RF Communication
LoRa stands for Long Range and is a proprietary wireless modulation technique developed by Semtech. Essentially, LoRa is the physical layer, or the hardware, that allows long-range communication between devices.
