7.1 Chapter Overview
This chapter briefly describes the security considerations of WiFi and LiFi network
interconnections with 5G networks. When designing 5G networks with short‐range
WiFi and LiFi connectivity, architectural considerations must be accompanied with
respective security considerations, and such security considerations are expected to
influence the architectural decisions. Therefore, this chapter proposes a security‐based
architectural model for short‐range wireless networks (WiFi) and high‐speed backbone
wireless networks (5G networks). In addition, this chapter explains the security
considerations of LiFi interconnection with 5G networks.
7.2 Introduction to WiFi‐5G Networks Interoperability
7.2.1 WiFi (Wireless Local Area Network)
WiFI (Wireless Fidelity) is the radio technology for short‐range communication that
works within licensed spectrum bands (2.4 GHz or 5 GHz ISM bands) through IEEE
802.11 standards. In general, two kinds of access modes, namely “infrastructure mode”
and “ad‐hoc mode”, are allowed with IEEE 802.11 radio interfaces. Carrier Sense
Multiple Access with Collision Avoidance (CSMA/CA) is the widely deployed protocol
to contend with and access the shared wireless channel in packet switched networks.
Access Points (AP) act as a “centralized controller” in the “infrastructure mode”, to
enable the nodes to communicate with the wireless network. On the other hand, nodes
within the ad‐hoc mode need to co‐ordinate themselves (no central controller) to
communicate with the neighboring nodes within the network.
