A Wide Area Network connects far remoted devices to the Internet through gateways. LoRa is such a subscription-free communication standard, supported by many companies. There is no overlap between LoRa and WiFi or Bluetooth. The latter have a very short range, LoRa a very narrow bandwidth. Since it is used mostly with sensors, the traffic can be slow and mainly unidirectional. LoRa also supports peer-to-peer communication.

El-cheapo wireless doorbells across the globe are so unoriginal it makes you wonder how much more e-rubbish we can tolerate in and around our homes. Luckily, we electronicz people have the power and skills to design and build our own personalised contraptions, personal here meaning programmable not just at the MCU level but also at the musical level with crude yet original (or not, whatever you prefer) melodies.

With test equipment such as oscilloscopes, innovations usually come at a slow pace and there is rarely anything really new. However, the IkaScope from the French company Ikalogic – mainly known for their logic analysers – has some very special features that I have never seen before, including a patented on/off system using the integrated probe tip. That means it’s time to get better acquainted with this remarkable instrument.

Under the theme “From Sensor to Sunset,” Arrow Electronics will display its comprehensive, fully integrated IoT portfolio at Embedded World, including sensors, wireless connectivity, gateways to cloud platforms, data aggregation and visualization, analytics and security, and beyond.

This video shows how to establish a peer-to-peer wireless LoRa communication. With a simple example based on Arduino, it explains how to update the data from a DHT11 temperature and humidity sensor to the ThingSpeak cloud. Before being able to send data from sensors to a cloud server, a beginning developer may need targeted assistance to quickly learn LoRa and IoT technology. That's why Elektor has chosen the new Dragino LoRa IoT Development Kit. Soon you too will turn your ideas into practical applications on the Internet of your own Things.

When Guglielmo Marconi claimed a monopoly on the use of radio waves around 1900, he was thwarted right away by national states. In 1906, they signed an international treaty stating that radio spectrum be ruled by national sovereignty. Since then, the use of radio spectrum has been strictly regulated. Although there are good reasons to organise the spectrum, the way in which this is done hinders progress. New technologies make it possible to allow more users in certain frequency ranges. This is necessary to facilitate the explosive growth of wireless devices. In addition, wireless connections are an important link in the chain to give access to over 3 billion people who do not yet have an Internet connection.

We all love Wi-Fi, Bluetooth, Zigbee, radio and television, mobile phones and various gadgets freed from any cable, as long as we don't worry about the electromagnetic pollution caused. Elektor Tapir is a tiny electronic device with an antenna, including two types of electromagnetic detectors and earphones. Sturdy and easy to build, this kit will sniff electro smog of almost any frequency.

Researchers from North Carolina State University have developed a system that can deliver several watts of power and at the same time has sufficient bandwidth to transmit video across the same wireless connection. In this manner a true single wireless connection is possible…
