“…HAN uses Wi-Fi for data transferring between smart home appliances and Wi-Fi AP while NAN uses LTE for the communication between AP and utilities. Fig.1 shows a Wi-Fi-LTE combination in smart grid communication based on the coexistence model designed in [20]. Smaller data rate and lower interference tendency make Wi-Fi to be used in HAN.…”

Long Term Evolution (LTE) is expanding its utilization in unlicensed band by deploying LTE Unlicensed (LTE-U) and Licensed Assisted Access LTE (LTE-LAA) technology. Smart Grid can take the advantages of unlicensed bands for achieving two-way communication between smart meters and utility data centers by using LTE-U/LTE-LAA. However, both schemes must co-exist with the incumbent Wi-Fi system. In this paper, several co-existence schemes of Wi-Fi and LTE technology is comprehensively reviewed. The challenges of deploying LTE and Wi-Fi in the same band are clearly addressed based on the papers reviewed. Solution procedures and techniques to resolve the challenging issues are discussed in a short manner. The performance of various network architectures such as listenbefore-talk (LBT) based LTE, carrier sense multiple access with collision avoidance (CSMA/CA) based Wi-Fi is briefly compared. Finally, an attempt is made to implement these proposed LTE-Wi-Fi models in smart grid technology.

Advanced metering infrastructure (AMI) of smart grid requires bidirectional communication for transferring data to billing center, for which WiFi is an attractive choice. However, WiFi operates in the unlicensed bands and LTE needs to offload data in the same unlicensed band. Recent release of 3.5 GHz (also termed as citizen broadband radio service (CBRS)) can be an attractive shared band where LTE and WiFi can coexist. In our study, we propose a fixed duty cycled LTE-U and WiFi based smart grid metering infrastructure where smart meter uses WiFi and data collector (termed as Access Point (AP)) of smart meters uses LTE for transferring data. We investigate the coexistence performance of LTE-WiFi in the 3.5 GHz band using a time division duplexing (TDD)-LTE confederated by WiFi along with FTP traffic model for system level simulation. The simulation results demonstrate a good neighboring coexistence between LTE and WiFi resulting a candidate AMI architecture for smart grid in the 3.5 GHz band.

“…Several studies have investigated the use of hybrid wireless network and LTE cellular network for SG [70] [25] [71] [72]. A hybrid WiFi mesh/LTE network is proposed in [70], even though the investigation is only on the performance of geographic routing protocol used in the mesh.…”

“…In these studies, clusterheads in WSN are equipped with dual-interfaces. In [72], control channel and random access channel performance of LTE network are measured and compared from three types of communications networks: LTE network, a hybrid IEEE 802.11/LTE network, and a hybrid IEEE 802.11s/LTE network. The wireless networks in these hybrid networks are used to aggregate local traffic.…”

“…Given that there will be thousands of IEEE 802.11s-based AMI networks that can be served by a base-station (i.e., eNB) of the LTE network, the overall performance of this hybrid AMI network has not been investigated yet, in particular the LTE network performance. Recently, preliminary study has been conducted in [72] for the LTE performance. Nevertheless, there are many aspects of LTE network that can be explored and investigated for this hybrid AMI network as the future work.…”

The tunneling mechanisms in the LTE network cause a downlink traffic problem to IEEE 802.11s. For the network interoperability, at the network layer of EPC network, a novel UE access list was proposed to address this issue. At the datalink layer, to handle QoS mismatch between IEEE 802.11s and LTE network, Dual Queues approach was proposed for the Enhanced Distributed Channel Access. The effectiveness of all proposed approaches was validated through extensive simulation experiments using a network simulator. The simulation results showed that the proposed approaches outperformed the traditional TCP/IP protocols in terms of end to end delay, packet delivery ratio, throughput, and collection time.
