For example, [6] introduces an optical-wireless access architecture where SDN controllers monitor the traffic conditions in both optical and wireless domains to dynamically adjust the uplink-to-downlink configuration of the LTE framing in ONU-eNB.
Hence, we propose a mixed-capacity wireless access (MCWA) architecture for WOBAN and study how to optimally place a limited number of additional radios at the wireless nodes to save the overall network cost.
Typical last mile wireless Internet access architecture comprises a gateway, e.g., an access point (AP) or a Base Station (BS), to which all clients are wirelessly connected (e.g., WiFi, WiMAX, LTE).
We identify fundamental and persistent differences between wired and wireless networking that will propel wired and wireless access network architectures on divergent evolutionary paths.
Moreover, the coexistence of diverse but complementary architectures and wireless access technologies is one of the major trends in 4G or next-generation wireless networks (4G/NGWN).
The distributed antenna system (DAS) is considered as a promising architecture for future wireless access.
On the other hand, wireless network cloud (WNC) [2] proposes an architecture to join wireless access systems to cloud computing and shift the processing of base stations with different technologies to a virtual cloud network.
In fact, engineering the software defined wireless cellular network involves to develop the network and control architecture covering both wireless access and core networks as well as the corresponding interfaces [150, 151].
Broadband Wireless Access (BWA) systems use new network architectures to deliver broadband services in a fixed point-to-point or point-to-multipoint configuration to residential and business customers.
Based on this, in our previous work [5, 6], we applied C/U-plane decoupled architecture to future professional high-speed railway wireless communication system to fulfill the wireless access desire of train passengers and the network architecture is depicted in Figure 1.
