Replying to: Mobile phone frequency spectrum allocations by PhilipP
Re: Mobile phone frequency spectrum allocations
In the U.S., the two major bands are cellular and PCS:
Cellular (800 / 850):
824 - 849 MHz (reverse link)
869 - 894 MHz (forward link)
PCS (1900):
1850 - 1910 MHz (reverse link)
1930 - 1990 MHz (forward link)
Forward link means tower-to-phone, reverse is phone-to-tower.
Each of those bands is sub-divided by both frequency and geography, and that is how licenses are assigned. For any one geographic point, there are two primary cellular licenses and six PCS licenses issued by the FCC. Those licenses can be subdivided and sold privately, however.
Notes:
- Nextel uses different spectrum (which is complex and changing).
- New bands are currently being set aside and prepared for auction by the FCC.
- Other parts of the world use different bands.
