1. A communications method comprising:
- using by an entity, over a first time interval, a first set of frequencies to provide communications;
refraining by the entity, over the first time interval, from using a second set of frequencies to provide communications in order to avoid subjecting a device to a first level of interference; and
using by the entity, over a second time interval that follows the first time interval, the second set of frequencies to provide communications, and subjecting the device to a second level of interference that is less than the first level of interference;
wherein the first set of frequencies and the second set of frequencies differ therebetween in at least one frequency.

Abstract
Embodiments of the invention provide reduced levels of interference to GPS receivers and/or to satellites. These embodiments allow frequencies that are proximate to GPS to be used by base stations and/or access points (such as femtocells) to provide forward and/or return link communications to user devices such as smartphones. Illustrative embodiments are provided wherein carriers of the 4G LTE standard (OFDM/OFDMA/SC-FDMA) are used by base stations and/or access points to provide wireless communications while reducing levels of interference to GPS and/or to satellites.

10. A communications system comprising:
-
a transceiver that is configured to use, over a first time interval, a first set of frequencies to provide communications and is further configured to refrain from using, over the first time interval, a second set of frequencies to provide communications in order to avoid subjecting a device to a first level of interference; wherein the transceiver is further configured to use, over a second time interval that follows the first time interval, the second set of frequencies to provide communications, and to subject the device to a second level of interference that is less than the first level of interference; wherein the first set of frequencies and the second set of frequencies differ therebetween in at least one frequency. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
