분류 전체보기21 OFDM Orthogonal Frequency Division Multiplexing Orthogonal Frequency Division Multiplexing (OFDM) Orthogonal Frequency Division Multiplexing (OFDM) is a digital multi-carrier modulation technique used in wireless communication systems, such as Wi-Fi, Digital Television (DTV), and Long-Term Evolution (LTE). OFDM is used to transmit multiple signals simultaneously over a single communication channel, allowing for increased bandwidth and improve.. 2023. 2. 5. NFC Communication NFC Communication Near Field Communication (NFC) is a short-range wireless communication technology that operates at a frequency of 13.56 MHz. It enables devices to communicate with each other over a distance of just a few centimeters. NFC is based on the principle of electromagnetic induction and uses a magnetic field to transmit data between two devices. How NFC Works NFC operates on the princ.. 2023. 2. 4. Bluetooth wireless technology theory Bluetooth is a wireless technology used for short-range communication between devices. It operates on radio waves and establishes a connection between devices with unique 48-bit addresses. Bluetooth defines a set of profiles for different types of device communication and has undergone several major revisions with increased range and speed. The most recent version, Bluetooth 5.0, offers increase.. 2023. 2. 4. 이전 1 2 3 4 다음
