    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.

  4. Radio spectrum - Wikipedia

    en.wikipedia.org/wiki/Radio_spectrum

    Radio-controlled toys may use portions of unlicensed spectrum in the 27 MHz or 49 MHz bands, but more costly aircraft, boat, or land vehicle models use dedicated radio control frequencies near 72 MHz to avoid interference by unlicensed uses. The 21st century has seen a move to 2.4 GHz spread spectrum RC control systems.

    The only difference between the signals is that the localizer is transmitted using lower carrier frequencies, using 40 selected channels between 108.10 MHz and 111.95 MHz, whereas the glideslope has a corresponding set of 40 channels between 328.6 and 335.4 MHz. The higher frequencies generally result in the glideslope radiating antennas being ...
