  2. 2.4 GHz radio use - Wikipedia

    en.wikipedia.org/wiki/2.4_GHz_radio_use

    Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. To reduce interference with other protocols that use the 2.45 GHz band, the Bluetooth protocol divides the band into 80 channels (numbered from 0 to 79, each 1 MHz wide) and changes channels up to 1600 times per second.

  3. 13-centimeter band - Wikipedia

    en.wikipedia.org/wiki/13-centimeter_band

    The 13 centimeter, 2.3 GHz or 2.4 GHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis. The amateur radio band is between 2300 MHz and 2450 MHz, and thereby inside the S-band. The amateur satellite band is between 2400 MHz and 2450 MHz, and its use by satellite ...

    en.wikipedia.org/wiki/List_of_WLAN_channels

    Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.

    Spektrum is a brand of radio control systems designed for use with hobby radio-controlled cars and aircraft. Spektrum is a division of Horizon Hobby . The R/C hobby in the United States, Japan, and Europe typically used to employ FM radio control in HF and VHF bands such as 27 MHz, 35 MHz, 49 MHz, and 72 MHz.

  7. Frequency-hopping spread spectrum - Wikipedia

    en.wikipedia.org/wiki/Frequency-hopping_spread...

    The transmitter and receiver can use fixed tables of frequency-hopping patterns, so that once synchronized they can maintain communication by following the table. In the US, FCC part 15 on unlicensed spread spectrum systems in the 902–928 MHz and 2.4 GHz bands permits more power than is allowed for non-spread-spectrum systems. Both FHSS and ...

  9. 3-centimeter band - Wikipedia

    en.wikipedia.org/wiki/3-centimeter_band

    The 3-centimeter or 10 GHz band is a portion of the SHF radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis. The amateur radio band is between 10.00 GHz and 10.50 GHz, and the amateur satellite band is between 10.45 GHz and 10.50 GHz. The allocations are the same in all three ITU regions. [1]
