METHOD AND SYSTEM FOR SOFT FREQUENCY REUSE IN A DISTRIBUTED ANTENNA SYSTEM
First Claim
1. A method for routing and switching operator RF signals, the method comprising:
- providing one or more Digital Remote Units (DRUs), each configured to receive one or more downlink radio frequencies and to transmit one or more uplink radio frequencies;
providing at least one Digital Access Unit (DAU) configured to communicate with at least one of the one or more DRUs;
wherein a first DRU in a first cell is operable to communicate using;
a first set of frequencies characterized by a first frequency band over a first geographic footprint; and
a second set of frequencies characterized by a second frequency band different from the first frequency band over a second geographic footprint including and surrounding the first geographic footprint;
wherein a second DRU in a second cell is operable to communicate using;
the first set of frequencies over a third geographical footprint; and
a third set of frequencies characterized by a third frequency band different from the first frequency band and the second frequency band over a fourth geographic footprint including and surrounding the third geographic footprint.

Abstract
A method for routing and switching operator RF signals includes providing one or more Digital Remote Units (DRUs) and providing at least one Digital Access Unit (DAU) configured to communicate with at least one of the one or more DRUs. A first DRU is operable to communicate using a first set of frequencies characterized by a first frequency band over a first geographic footprint and a second set of frequencies characterized by a second frequency band different from the first frequency band over a second geographic footprint including and surrounding the first geographic footprint. A second DRU is operable to communicate using the first set of frequencies over a third geographical footprint and a third set of frequencies characterized by a third frequency band different from the first frequency band and the second frequency band over a fourth geographic footprint including and surrounding the third geographic footprint.

7. A method of distributing communications frequencies, the method providing:
-
providing a set of communications units; transmitting and receiving, from a first communications unit of the set of communications units; a first set of frequencies characterized by a first frequency band and a first geographic footprint; and a second set of frequencies characterized by a second frequency band different from the first frequency band and a second geographic footprint larger than and at least partially surrounding the first geographic footprint; and transmitting, and receiving, from a second communications unit of the set of communications units; a third set of frequencies including one or more frequencies in the first frequency band and a third geographical footprint; and a fourth set of frequencies including one or more frequencies in a third frequency band and a fourth geographical footprint larger than and at least partially surrounding the third geographical footprint. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
