A communication system comprising: a station moving relative to a geographic area; a plurality of antennas included in the station; one or more processors included in the station, the one or more processors configured to: control a first antenna of the plurality of antennas to output a primary beam to cover the geographic area, wherein the primary beam is associated with a primary cell having a first center frequency; control a second set of antennas of the plurality of antennas to output a plurality of secondary beams (320A-G) to cover a plurality of locations within the geographic area, wherein the plurality of secondary beams each has a beam angle smaller than the primary beam, and the plurality of secondary beams are all associated with a secondary cell having a second center frequency; control the first antenna to establish using the primary beam a first communication link between a client device and the primary cell such that the client device is in a radio resource control -idle state on the primary cell; determine that the client device transitions from the RRC-idle state to an RRC-connected state on the primary cell; determine that the client device is at a location covered by a first secondary beam outputted by a given one of the second set of antennas; control the given one of the second set of antennas to establish, using the first secondary beam, a second communication link between the client device and the secondary cell; and instruct the client device to bond the primary cell and the secondary cell using carrier aggregation. a station moving relative to a geographic area; a plurality of antennas included in the station; one or more processors included in the station, the one or more processors configured to: control a first antenna of the plurality of antennas to output a primary beam to cover the geographic area, wherein the primary beam is associated with a primary cell having a first center frequency; control a second set of antennas of the plurality of antennas to output a plurality of secondary beams (320A-G) to cover a plurality of locations within the geographic area, wherein the plurality of secondary beams each has a beam angle smaller than the primary beam, and the plurality of secondary beams are all associated with a secondary cell having a second center frequency; control the first antenna to establish using the primary beam a first communication link between a client device and the primary cell such that the client device is in a radio resource control -idle state on the primary cell; determine that the client device transitions from the RRC-idle state to an RRC-connected state on the primary cell; determine that the client device is at a location covered by a first secondary beam outputted by a given one of the second set of antennas; control the given one of the second set of antennas to establish, using the first secondary beam, a second communication link between the client device and the secondary cell; and instruct the client device to bond the primary cell and the secondary cell using carrier aggregation. control a first antenna of the plurality of antennas to output a primary beam to cover the geographic area, wherein the primary beam is associated with a primary cell having a first center frequency; control a second set of antennas of the plurality of antennas to output a plurality of secondary beams (320A-G) to cover a plurality of locations within the geographic area, wherein the plurality of secondary beams each has a beam angle smaller than the primary beam, and the plurality of secondary beams are all associated with a secondary cell having a second center frequency; control the first antenna to establish using the primary beam a first communication link between a client device and the primary cell such that the client device is in a radio resource control -idle state on the primary cell; determine that the client device transitions from the RRC-idle state to an RRC-connected state on the primary cell; determine that the client device is at a location covered by a first secondary beam outputted by a given one of the second set of antennas; control the given one of the second set of antennas to establish, using the first secondary beam, a second communication link between the client device and the secondary cell; and instruct the client device to bond the primary cell and the secondary cell using carrier aggregation.
