Where is OFDM used?
Orthogonal frequency division multiplexing (OFDM) is a modulation technique that is used in several applications ranging from cellular systems (3GLTE, WiMAX), wireless local area networks (LANs), digital audio radio, underwater communications, and even optical light modulation.
What is OFDM and how it works?
Orthogonal frequency-division multiplexing is a method of data transmission where a single information stream is split among several closely spaced narrowband subchannel frequencies instead of a single Wideband channel frequency.
Is Bluetooth a OFDM?
BT uses frequency hopping to hop over the entire 2.4 GHz band, while 802.11g, on the other hand, uses OFDM and occupies approximately one third of the 2.4 GHz band. As a result, BT hops on to 802.11g transmissions. The impact of mutual interference depends on the utilization and proximity of both devices.
Is Wi-Fi a OFDM?
802.11a/g/n/ac radios currently use Orthogonal Frequency Division Multiplexing (OFDM) for single-user transmissions on an 802.11 frequency. 802.11ax radios can utilize Orthogonal frequency-division multiple access (OFDMA) which is a multi-user version of the OFDM digital-modulation technology.
