    Great Video! So a few questions... So just because it's called the 900Mhz band, it uses a lowest point of 890Mhz? The Same with the 1800 MHZ band... it's called 1800 but it starts at 1710 MHZ? Also.. These GSM bands, are these specific bands like the GSM 900, 1800 and 1900 owned by a specific cell carrier like AT&T, or Verizon? Or can any carrier use these GSM bands? If any carrier can use them...then technically who "owns" this spectrum?

    Sir I have given a data of satellite multispectral image 1573 pixel of the city where 5parameter are given
    X-coordinate is a numeric vector
    Y- coordinate is a numeric vector
    Band 1- numeric vector
    Band 2- numeric vector
    Band 3- numeric vector
    Now my Question is In these three bands some values are given negative thus it may be possible or not
    Q2- how can we identify these three frequency band units and it's which colur (blue, red ,green )
