Some demonstrative embodiments include devices, systems and/or methods of communicating between a cellular manager and a User Equipment (UE) via a Wireless Local Area network (WLAN) node. For example, an Evolved Node B (eNB) may be configured to communicate with a User Equipment (UE) traffic of at least one Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) Radio Access Bearer (E-RAB); to participate in establishment of an IP tunnel with the UE via a Wireless Local Area Network (WLAN) node; to encapsulate an IP payload comprising downlink traffic of the E-RAB in an IP tunneling packet; and to send the IP tunneling packet to the UE via the IP tunnel.
