Classification: CPC H | IPC H

Claim 8:
9. A system for monitoring cellular communications, comprising:
a passive sensor device, including:
one or more radios;
one or more processors; and
one or more memory devices having stored thereon instructions that when executed by the one or more processors cause the one or more processors to:
identify one or more active downlink channels using at least one of the one or more radios to monitor channels in a cellular spectrum for downlink activity, wherein the at least one of the one or more radios monitoring the channels in the cellular spectrum for downlink activity is a first software defined radio;
store downlink channel information, including configuration data, for the identified one or more active downlink channels;
identify one or more active uplink channels using at least one of the one or more radios to monitor the channels in the cellular spectrum for uplink activity, wherein the at least one of the one or more radios monitoring the channels in the cellular spectrum for uplink activity is a second software defined radio that is different from the first software defined radio;
store uplink channel information for the identified one or more active uplink channels;
correlate at least one of the one or more active uplink channels with a corresponding one of the active downlink channels;
tune at least one of the one or more radios to the at least one active uplink channel using the configuration data for the corresponding active downlink channel;
tune at least one of the one or more radios to the active downlink channel corresponding to the at least one active uplink channel using the corresponding configuration data; and
capture information related to a mobile wireless device communicating on the at least one active uplink channel and the corresponding active downlink channel.
