LoRa (Long Range) is a type of wireless communication technology designed to send information over long distances with low power consumption. It uses a special technique called chirp spread spectrum (CSS) modulation, which operates by continuously changing the frequency of a transmitted signal over time. This varying frequency generates a waveform (resembling the sound of…

Nearly all the devices we use today — from smartphones, tablets, wearables, and even many of our appliances — connect to the Internet via a home (or office) WiFi network. Internet access to smart devices is typically managed through a web interface or mobile app. Similarly, when we’re out and about, we’ll access WiFi for…

Keysight Technologies recently enabled Quectel to verify that its Internet of things (IoT) wireless modules support the latest 5G reduced capability (RedCap) and non-terrestrial networks (NTN) features by establishing end-to-end data call connections using the Keysight S8711A UXM 5G Test Application. This achievement accelerates Quectel’s development of 3GPP 5G Release 17 (Rel-17) compliant designs. Based on the…

Typically, a WiFi network has a range that’s above 45 meters. The signals are strongest near the router. The further away you move, the weaker the signal. The same is true of thick walls or additional floors in a home or building. The WiFi signals could be completely lost on other floors of a premise. …
