  2. Crystal oscillator frequencies - Wikipedia

    en.wikipedia.org/wiki/Crystal_oscillator_frequencies

    Half the 16.368 MHz frequency; same use in different chipsets. 8 times the 1.023 MHz C/A GPS signal chipping rate. Multiplied by 192.5 to get the 1575.42 MHz L1 frequency and multiplied by 150 to get the 1227.60 MHz L2 frequency. 8.192 ISDN: 256000 audio Allows binary division to 1 kHz (2 13 ×1 kHz). Used in ISDN systems.

    en.wikipedia.org/wiki/Cellular_frequencies_in...

    The 1850–1990 MHz PCS band is divided into six frequency blocks (A through F). Each block is between 10 MHz and 30 MHz in bandwidth. License (A or B) is granted for Major Trading Areas (MTAs). License (C to F) is granted for Basic Trading Areas (BTAs). License (G), where issued, is granted for Economic Areas (EAs).

    Medium Frequency (MF) (0.3 to 3 MHz) 630 metres (472 to 479 kHz) High Frequency (HF) (3 to 30 MHz) see Table of amateur MF and HF bandplans; Very High Frequency (VHF) (30 to 300 MHz) 8 metres (39.9 to 40.7 MHz), Republic of Ireland, Slovenia and South Africa. Beacons in UK and Denmark

  5. L band - Wikipedia

    en.wikipedia.org/wiki/L_band

    The Global Positioning System carriers are in the L band, centered at 1176.45 MHz (L5), 1227.60 MHz (L2), 1381.05 MHz (L3), and 1575.42 MHz (L1) frequencies. L band waves are used for GPS units because they are able to penetrate clouds, fog, rain, storms, and vegetation.

  6. List of WLAN channels - Wikipedia

    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.

  7. Extremely high frequency - Wikipedia

    en.wikipedia.org/wiki/Extremely_high_frequency

    Extremely high frequency (EHF) is the International Telecommunication Union designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). [ 1 ] [ 2 ] It is in the microwave part of the radio spectrum, between the super high frequency band and the terahertz band .
