LoraWAN Classes
LoRaWAN Device Classes · The LoRaWAN specification defines three device classes. Class A · At any time an end node can broadcast a signal. After this uplink transmission (tx) the end node will listen for a response from the gateway. · The end node opens two receive slots at t1 and t2 seconds after an uplink transmission. The… Continue reading LoraWAN Classes
LoRaWAN – Rules and regulations
ISM Band LoRa operates in the unlicensed ISM (Industrial, Scientific and Medical) radio band that is available worldwide. In India, LoRaWAN operates in the 865-868 MHz frequency band. Devices such as microwave ovens, medical equipments or baby monitors all uses the ISM band ISM band advantages: Anyone can use these frequencies. No license… Continue reading LoRaWAN – Rules and regulations
LoRaWAN Network and Components.
LoRa LoRa is an acronym for Long Range, and it is a wireless technology where a low powered sender transmits small data packages (0.3 kbps to 5.5 kbps) to a receiver over a long distance. LoRa is a physical proprietary radio communication technique. It is based on spread spectrum modulation techniques derived from chirp spread… Continue reading LoRaWAN Network and Components.
Low Power Wide area network
LPWAN stands for Low Power Wide Area Network and this type of wireless communication is designed for sending small data packages over long distances, operating on a battery. There are several competing technologies in the LPWAN space such as Narrowband IoT (NB-IoT), Sigfox, LoRa and others. LPWAN is not a single technology, but a group… Continue reading Low Power Wide area network

LoRaWAN Demo
There are two methods for Raspberry Pico and Pico-LoRa-SX1262 to connect to the network via LoRaWAN: OTAA (Over-The-Air-Activation) and ABP (Activation By Personalization). Here we use OTAA, as shown below. Step 1: Please send the “Join-Request” message to the network to be added, and note that the adding process is always initiated by the end… Continue reading LoRaWAN Demo
Introduction to LoRaWAN
LoRaWAN is a low-power wide area network open protocol based on LoRa radio modulation technology. Aims to wirelessly connect battery-powered “things” to the Internet in a regional, national, or global network and targets key Internet of Things (IoT) requirements such as bi-directional communications, end-to-end security, mobility, and localized services. Node wireless connection to the Internet… Continue reading Introduction to LoRaWAN
Introduction LoRA
LoRa (short for long range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. Semtech’s LoRa is a long range, low power wireless platform that has become the de facto wireless platform of Internet of Things (IoT). LoRa devices and networks such as the LoRaWAN® enable smart IoT applications that solve… Continue reading Introduction LoRA
