Zilia is specialized in the development and production of connectivity devices. There are several product options based on LoRa®, one of the main technologies in LPWAN, which allow you to interconnect devices in national and international networks, in addition to restricted-range networks, using the same hardware.
Peer-to-peer communication in LoRa®
Modern LPWAN networks (Low Power Wide Area Network) extend over a wide territorial area, allowing the implementation of various applications of the so-called Internet of Things (IoT), previously possible only in cellular networks. These networks require communication infrastructure spread over the coverage area connected to the Internet, which entails high costs of managing the operation. However, most applications do not need a very wide coverage area.
In such cases, Wi-Fi, ZigBee®, 6LoWPAN, WiSUN® technologies or other proprietary forms of digital communication are very common options.
Recently, LoRa® has been a viable technology option, as it allows the deployment of a private network with or without private gateways.
No gateways?
LoRa® technology allows communication directly between devices, eliminating the need for a gateway.
With a little development effort, it is possible to implement a communication network. This architecture is commonly referred in the market as peer-to-peer or P2P.
As an example, we can mention a building automation system, with sensors installed dispersed on several floors. Sensors (connected to devices) must send some information to a central. In this way, it is possible to generate commands to the system in a minimum time interval and, after these actions, send the data to the central.
By opting for the highly jamming resistant LoRa® P2P modulation, you get incredible signal penetration and low power consumption. These characteristics are possible because LoRa®´s digital modulation is based on spread spectrum technology, allowing a good propagation of the transmitted signals, even in the presence of obstacles (obviously with limitations).
In addition to other features, Zilia’s LoRa® module allows peer-to-peer communication to be easily programmed through AT commands. Likewise, the module allows the use of other proprietary AT commands, which help and simplify the application of other elements in the system, be it a digital or analog sensor or even some other sub-system that is connected by serial communication.
All these qualities have demonstrated a great compatibility of LoRa® in peer-to-peer mode in applications such as alarm systems, fire systems, risk area telemetry and any and all remote triggering or telemetric data acquisition. Several customers have already developed these applications using LoRa® modules from Zilia.
