Concept
Short-range communication refers to wireless communication technologies designed for close proximity data exchange, typically within a range of a few centimeters to a few meters. These technologies are crucial for applications like contactless payments, data transfer between devices, and Internet of Things (IoT) connectivity, offering benefits like low power consumption and high data transfer rates over short distances.
Relevant Fields:
Concept
Near Field Communication (NFC) is a short-range wireless technology that enables data exchange between devices when they are in close proximity, typically within a few centimeters. It is widely used for contactless payment systems, secure access, and data sharing due to its ease of use and security features.
Concept
Bluetooth is a wireless technology standard that enables the exchange of data over short distances between fixed and mobile devices, creating personal area networks (PANs). It is widely used for connecting peripherals like headphones, keyboards, and mice to computers and smartphones, as well as for data transfer between devices.
Concept
Infrared communication is a wireless technology that uses infrared light to transmit data over short distances, commonly used in remote controls and short-range communication between devices. It requires a clear line of sight between the transmitter and receiver, and is limited by range and interference from ambient light.
Concept
Radio Frequency Identification (RFID) is a technology that uses electromagnetic fields to automatically identify and track tags attached to objects. These tags contain electronically stored information, which can be read from a distance without direct contact or line of sight, making RFID a powerful tool for inventory management, access control, and asset tracking.
Concept
Concept
Data Transfer Protocols are standardized rules that govern how data is transmitted between devices across a network, ensuring reliability, efficiency, and security in communication. They are essential for interoperability between different systems and are fundamental to the functioning of the internet and other digital networks.
Concept
Concept
Coarse Wavelength-Division Multiplexing (CWDM) is a technology that multiplexes multiple optical carrier signals on a single optical fiber by using different wavelengths of laser light. It is designed for short-range communication and is cost-effective, making it suitable for metropolitan area networks and access networks where high bandwidth is not a primary requirement.
Concept
Bluetooth Low Energy (BLE) is a wireless communication technology designed for short-range data exchange with minimal power consumption, making it ideal for Internet of Things (IoT) devices. It operates in the 2.4 GHz ISM band and uses a simple protocol stack to ensure efficient and secure data transmission.
