In some examples, the transmitter module 1330 may be an example of one or more aspects of the transmitter module 1230 described with reference to FIG. 12. In some examples, the transmitter module 1330 may include at least one RF transmitter, such as at least one RF transmitter operable to transmit over the licensed radio frequency spectrum band and/or the unlicensed radio frequency spectrum band. The transmitter module 1330 may in some cases include separate transmitters for the licensed radio frequency spectrum band and the unlicensed radio frequency spectrum band. The separate transmitters may, in some examples, take the form of a licensed LTE/LTE-A RF spectrum band transmitter module 1332 for communicating over the licensed radio frequency spectrum band, and an unlicensed LTE/LTE-A RF spectrum band transmitter module 1334 for communicating over the unlicensed radio frequency spectrum band. In some examples, the transmitter module 1330 may also include a Wi-Fi RF spectrum band transmitter module 1336. In examples in which the apparatus 1305 includes a base station, the transmitter module 1330 may include a backhaul transmitter module 1338. The transmitter module 1330, including the licensed LTE/LTE-A RF spectrum band transmitter module 1332, the unlicensed LTE/LTE-A RF spectrum band transmitter module 1334, the Wi-Fi RF spectrum band transmitter module 1336, and/or the backhaul transmitter module 1338 may be used to transmit various types of data and/or control signals (i.e., transmissions) over one or more communication links and/or backhaul links of a wireless communication system, such as one or more communication links and/or backhaul links of the wireless communication system 100 and/or 200 described with reference to FIGS. 1 and/or 2. The communication links and/or backhaul links may be established over the licensed radio frequency spectrum band and/or the unlicensed radio frequency spectrum band (and/or over one or more wired or wireless connections with, for example, a core network such as the core network 130 described with reference to FIG. 1).
