1. A system for monitoring cellular communications, comprising:
a passive sensor device, including:
at least four 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 the first radio to monitor channels in a cellular spectrum for downlink activity;
store downlink channel information, including configuration data, for the identified one or more active downlink channels;
identify one or more active uplink channels using the second radio to monitor the channels in the cellular spectrum for uplink activity;
correlate at least one of the one or more active uplink channels with a corresponding one of the active downlink channels;
tune the third radio to the at least one active uplink channel using the configuration data for the corresponding active downlink channel; and
tune the fourth radio to the active downlink channel corresponding to the at least one active uplink channel using the corresponding configuration data.
