The following table shows the bandwidths for each type of system.
For example, the
A
band for 1900 MHz PCS has the fixed 15 MHz filter centered
at 1937.5 MHz for the downlink and 1857.5 for the uplink.
1
30 MHz pass filter can be positioned along the 75 MHz DCS 1800 band. Order product with uplink and
downlink frequency at 1.25 MHz spacing. For example an uplink center frequency of 1737.5 MHz will provide
a 30 MHz band between 1722.5 MHz and 1752.5 MHz and a downlink center frequency of 1832.5 MHz will
provide a 30 MHz band between 1817.5 MHz and 1847.5 MHz.
2
Similar to above, the 1900 PCS 15 MHz filter can be positioned along the 60 MHz band.
The LG
Cell
covers a 30 MHz band in frequency range of 1710 MHz to 1785 MHz
on the uplink and 1805 MHz to 1880 MHz on the downlink. The operator can
choose where to place the 30 MHz band of operation by choosing the corresponding
center frequencies as shown in the following table
