Satellite communication systems use complex modulation schemes to achieve the blazingly fast data rates required to deliver video and broadband data. To attain this, they must deliver high RF output power while simultaneously ensuring the signals retain their desired characteristics. The new GMICP2731-10 GaN MMIC power amplifier from Microchip Technology helps meet both of these…

STMicroelectronics, a global semiconductor provider, has launched a new low-power Bluetooth module from Lierda Science & Technology Group — a high-tech enterprise that provides IoT system and smart product solutions in China, uses an ST STM32WB55 Bluetooth LE (BLE) microcontroller (MCU). With its stamp-type format, Lierda’s LSD1BT-STWB5500 module is highly integrated yet resistant to interference.…

To deploy today’s Wi-Fi 6 access points (APs) and 5G small cell access nodes, it’s first necessary to access AC power or a switch that can deliver both power and data as required. Microchip Technology Inc. has created a more flexible and cost-effective alternative with the first multiport Power-over-Ethernet (PoE), power-sourcing equipment (PSE) injector —…

The ST25R3918 from STMicroelectronics is a multi-purpose NFC transceiver, supporting passive peer-to-peer functionality, NFC card-emulation mode, and NFC reader operation. Delivering most of the functionality of the flagship ST25R3916 NFC reader at a competitive price, the ST25R3918 enables use cases such as accessory identification for a wide range of applications — including power tools and personal healthcare…

The Cambridge Research Laboratory of Toshiba Europe announced the first demonstration of quantum communications over optical fibers, exceeding 600 km in length. The breakthrough will enable long-distance, quantum-secured information transfer between metropolitan areas and is a major advance toward building the future Quantum Internet. The term Quantum Internet describes a global network of quantum computers…

The electromagnetic radio spectrum is a natural resource which is licensed and allocated by the government for the use of transmitters and receivers. A spectrum is a collection of wavelengths of radio frequency waves which are available for wireless communication services. These wavelengths are broken down and brackets of these (called ‘Bands’) are allocated for various purposes such as GSM/HSPA, 3G, 4G, TV, Wi-Fi, defense communication, radio broadcasting, mobile satellites, aeronautical satellites, etc. The electromagnetic spectrum is a resource which cannot be depleted but can be over crowded in some bands more than the others due to this static allocation.  

Wireless Power Transfer (WPT) is a technology that allows the transfer of electric power without wires. Based on technologies using electric, magnetic, or electromagnetic fields, WPT is capable of supplying power from a standard AC source to the batteries and devices which are compatible, without any physical connectors. This technology utilizes the electromagnetic field generated…

This year has been characterized by rapid changes in engineering technology and production. For example, wearables that used to only track the date, time, and a user’s steps can now monitor one’s blood pressure, sleep habits, and stress levels. This means devices, including smartphones, must provide real-time data on multiple variables whenever requested to be…

The ubiquitous nature of the internet is probably a major reason for making our lives the way it is today. In the present scenario, it has become a necessity of the modern world. Its capabilities are not limited to over knowledge regarding the usage of Wi-Fi. Another superior technology of Li-Fi is ultimately going to change our perception of the internet.Wi-Fi is a commonly used wireless technology which uses radio waves to connect devices to the internet but with the growing demands and increase in the network congestion, the present technology won’t be able to deliver the desired results for a long time. Consequently, while exploring the possibility of alternate choices the term ‘Li-Fi’ was devised. Here we are going to illustrate the concept of Li-Fi technology, how does it work, and how is it different from the conventional Wi-Fi technology.
