1. A communication system comprising:
a memory that stores at least one application that, when activated, has a communication demand requirement comprising at least one of: (i) data throughput greater than a throughput threshold; (ii) data latency less than a latency threshold; and (iii) a level of quality;
a radio frequency (RF) communication subsystem having more than one communication chain comprising at least a first communication chain and a second communication chain configurable to operate in at least one of carrier aggregation mode and dual connection mode to satisfy the communication demand requirement; and
a controller communicatively coupled to the memory and the RF communication subsystem, and which:
in response to: (i) determining that the RF communication subsystem is not currently connected to one or more network nodes; and (ii) determining that the at least one application will require a data connection with a communication network:
scans, via components of the RF communication subsystem, one or more available network nodes to assess communication capacity;
identifies a combination of a primary band and at least one secondary band of the one or more available network nodes that satisfies the communication demand requirement; and
selects and camps on the primary band in preparation for activation of the at least one application and configures the RF communication subsystem to use the at least one secondary band in preparation for activation of the at least one application and for establishment of the data connection with the communication network.
