long distance

LoRa has a low transmission rate but high sensitivity. Its transmission distance is much longer than other wireless communication technologies. It can transmit several kilometers in outdoor environments and even cover long distances in urban environments. Therefore, it is suitable for applications with long distance, low speed and small data volume.

Low power consumption

LoRa technology uses a low-power transmission method, allowing the device to work for a long time under battery power. This feature is ideal for devices that require long-term operation and are difficult to replace batteries, such as sensor nodes, smart city equipment, etc.

Strong anti-interference ability

LoRa uses spread spectrum technology, which gives it excellent anti-interference capabilities. When encountering external electromagnetic signal interference during communication, LoRa can continue to communicate stably, while traditional wireless technology cannot communicate.

What is LoRa MESH?
LoRa MESH is an ad hoc network communication protocol based on LoRa technology. Using LoRa wireless communication technology, multiple devices form a self-organized network to form a mesh topology to realize interconnection between devices. It has both the advantages of LoRa technology and the characteristics of Mesh ad hoc networks.

Mesh ad hoc network: Mesh network is "wireless mesh network". The nodes in the Mesh network topology are interconnected, have high utilization rate, and have strong network self-healing properties.


Ad hoc network characteristics

LoRa MESH network has the characteristics of self-organizing network and can automatically establish and maintain the network. When a device joins or leaves the network, the network automatically adjusts the topology to ensure the stability of data transmission. This self-organizing network feature makes the LoRa MESH network highly flexible and scalable.

Routing node: Routing node receives data in the network for routing updates and data forwarding.
Terminal node: Terminal nodes do not have routing functions and are generally deployed at the edge of the network.

multi-hop transmission

The LoRa MESH network uses multi-hop transmission, and data can be forwarded through multiple nodes and finally reaches the target node. This multi-hop transmission method can effectively extend the communication distance, improve signal penetration capabilities, and reduce the communication pressure of a single node.

Low power consumption

The low-power design allows the device to maintain a long working time while transmitting data. This is especially important for devices that need to run for a long time, such as smart homes, environmental monitoring and other fields.


high capacity

Multi-hop communication improves the capacity and reliability of the network. Even if a node fails, data can still be transmitted through other paths. Therefore, LoRa MESH has a high capacity and can support the access of a large number of devices. This makes the LoRa MESH network very suitable for large-scale IoT scenarios, such as smart cities, smart agriculture, etc.

low cost
LoRa MESH uses low-cost equipment and solutions to lower the cost threshold for IoT applications. More enterprises and developers can participate in innovation and applications in the field of Internet of Things.

Wide range of applications

The LoRa MESH network can be widely used in smart home and industrial sensors, wireless alarm security systems, building automation solutions, smart agriculture and other application scenarios because of its characteristics of automatically forming a network and supporting the access of large quantities of devices.

LoRa MESH technology communication method

Ebyte's LoRa MESH network supports four communication methods, Unicast, Multicast, Broadcast and Anycast. Users can choose different communication methods according to different application scenarios.

Among them, unicast and broadcast are the simplest and most basic communication methods. Under unicast, routing will be automatically established and request responses will be returned to determine the data transmission path. In broadcast mode, all routing nodes will start a data relay after receiving data.

The multicast mechanism is relatively complex and can achieve one-to-many communication. Users need to configure the multicast group address first, similar to a public address. Anycast is usually used for data exchange between different networks. Data will not be forwarded under anycast. Under anycast, two communication methods, unicast and broadcast, can be implemented depending on the target address. Users can transmit any data to any module within the communication range.


What is LoRaWAN?

LoRaWAN is also an IoT communication protocol based on LoRa technology. Its main features are low power consumption, long distance and wide area coverage. Its main purpose is to achieve interconnection and interoperability between IoT devices.
How LoRaWAN works

In LoRaWAN, IoT devices transmit data to the gateway through the LoRa module, and the gateway transmits the data to the cloud server through Ethernet for storage and processing. IoT devices in LoRaWAN can communicate using different frequency bands to meet the needs of different application scenarios. At the same time, LoRaWAN also supports a variety of different data transmission methods, including unicast,  multicast and broadcast.
