What is WM1302 Lorawan and its Benefits?

Low-power wide-area networks or LPWANs are long-range wireless communications that can connect various sensors. The LoRa and both LoraWAN are part of the wireless communication of non-cellular LPWAN, and they are all operating in license-free spectrums.

The LoRa, or long range, has a wide range of uses in the internet of things or IoT technology. The LoRa was able to transmit frequency bands from 169 to 915 MHz that’s been used for more than ten kilometers by using only low power. With this said, they have proven to be great assets for various industries.

Then, there are different gateway modules used in the system. One of the best examples is the WM1302 Lorawan, designed to be used in various LPWAN gateways. Some of the benefits to know are the following:

Long Range Deployment: LoraWAN has been known to cover a wide area. It can reach approximately 5 km, while it can be up to 10 km in cities and rural localities.

More Years of Battery: The usage of low power required to send data over long distances enabled more battery life. The devices can run up to a decade or more.

End-to-End Encryption: Security is a priority when it comes to this technology. This is where the end-to-end encryption applies with the help of various algorithms and 128-bit cryptographic keys. The first layers are often used for the network servers and the end devices, so everything is secured.

Geolocation: There are passive and effective geolocation solutions that the technology provides. This can track various devices without needing GPS to be inserted into the devices. This geolocation is determined by the time difference on arrival triangulation that’s part of the LoraWAN operation.

Firmware Updates: There is an option for updates on air where everything is simplified. The end devices are getting updates anytime, which is convenient for the owners.

Effective in Indoor Settings: The LoRa modulation has deep penetration and coverage in indoor settings. They can reach the parking sensors even if they are underground or the utility meters in the attic. See more about LoRa on this site here.

Options for Private and Public Deployment: This technology provides a more flexible private or public deployment network. The public deployment usually involves telecom operators, backhauls, and gateways where many consumers have to pay for the operators to get connected. There are also private ones that are known to get deployed by their owners on their own with long-range gateways.

What Does the Lorawan Topology Look Like?

The network architecture can be based on the star-of-stars topology, where the data relies on a primary network server and sensor nodes. The communication between these stations and nodes goes through the wireless channels that utilize the physical layer of the LoRa. On the other hand, the connection between the central server and the gateway is handled by an IP-based network.

Gateways: The gateways are often responsible for relaying messages between a network server and an end device with the help of an IP.

End Nodes: They are responsible for directly transmitting the gateways within a specific range with the help of the LoRa.

The end nodes can consist of transponders, sensors, and microcontrollers. The sensors might help detect location, temperature, humidity, and accelerometer. They are often in the move in detecting changing parameters while the transponder is transmitting the signals over a patented transmission that uses radio waves.

Micro-controllers can now be programmed in Javascript or Python, where the developers are able to detect various algorithms in the system. This is where the devices can detect temperatures and accelerometers according to how they are programmed.

Batteries power the node sensors or LoraWAN end nodes with low power usage. The sensors can activate for 5 to 6 years, depending on the use and the model, and the transmitted signal can range from 1 km to 10 km, depending on the area.

About the Gateways

The gateways are the ones transmitting data, and they are connected to the world wide web. The connections to the servers are made through IP, and they essentially convert the RF packets into IP ones because they serve as bridges.

There are also network servers where cloud-based services and products can exist. The data packets are connected to the network servers and rerouted to their essential applications. There are options for downlink or uplink communications present in the server.

About the LoraWAN Security

One of the concerns of many owners is their data security, which is understandable. Security is usually more important when massive amounts of data are being deployed from the Internet of Things, and fortunately, the LPWAN is very secure.

Two layers of security are used in the system. The first one is for the application, while the other is exclusively applied to the network. Security is often applied by authenticating nodes and ensuring that the network operators don’t have access to an existing app’s data. There are also several layers of cryptography present where information is encrypted 2x.

The sensor is node-encrypted, and the LoraWAN protocol is then securing it. This is then sent to the gateway, which sends data to the usual IP network and the server. There are also session keys that help to decrypt the data. It’s very important to have the keys so that the gateway can receive data from sensors that are present in a building or room.

Communication protocols involving LoraWAN can have added encryption. As mentioned, the transmission is through radio waves, so they can be almost impossible to decrypt. The devices may join various networks that are operating through over-the-air-activation, where the network and the devices can exchange the 128-bit keys. There’s also the NwkSkey that guarantees the integrity of the message sent to the LoRa server, so everything is pretty secure.

There’s also an option to do the activation by personalization. This is a method where the users insert the session keys into the device. However, this can cause security problems in the future when unauthorized people have gotten a hold of the key.
