Therefore, with the 5G technology along with the wireless devices and smart components, a solid technological advancement is going to take place. 

Technical backgrounds

Every new technology comes from one previous solution that needs to be improved or add some features in it. In that respect, WLAN and 5G technology have also have become the most advanced technology during evolution. However, the technological background of both the technologies also needs to be reviewed to make further changes or improvements by the developers.

WLAN technology:  Network engineers have set up the appropriate point to a high-speed network hub in a centralized network to make the network more accessible. The controlling wireless device in a typical corporate office WLAN system is usually located in a central corridor and is known as an Access Point (AP) radio. A few of these APs are often placed throughout a complex to provide enough coverage to all workplaces. The same idea applies to an internal network, where one network device is generally enough [4]. At the moment, laptops, tablets, smartphones, and other devices are the primary consumers of WLANs. Nevertheless, in the future, more products will use the WLAN system to communicate. Personal computers, cameras, equipment, and other daily things, for example, will increasingly rely on WLAN future technology integrated with WLAN technology.

5G technology: 5G refers to the fifth evolution of mobile networks. After 1G, 2G, 3G, and 4G networks, it is a globalized communication network. 5G offers a new type of structure capable of connecting nearly everyone and everything, especially organizations, products, and gadgets. 5G wireless technology is designed to provide more users with better multi-Gbps maximum data rates, super low congestion, increased dependability, huge available bandwidth, enhanced availability, and more consistent customer satisfaction [3]. Higher system efficiency enables better customer engagement while also connecting new industries. This has a far higher influence than earlier network versions. The new 5G channel’s growth demands are also moving beyond conventional mobile networking companies to business areas such as the automobile industry, gaming sector, multimedia, and many other industries.

Potential benefits 

The potential benefits of the 5G and WLAN technology are helping to improve the wireless network. The combination of two technology increases speed and capacity to the potential industry. There are many benefits are available but few are discussed below.

5G technology: 5G networks improve the quality of the new applications, industries, and business models. The technology requires a data rate and massive connectivity for the new applications. The key factor of the 5G generation is to increase their networks towards the business and fast broadband connections. This connected device will be accessing an instant connection to the internet, which improves the quality of the cities. Choose a better route for sending data information in real-time. The 5G network increases a download speed day by day and decreases the latency [5].  This speed will be maximized the browsing experience and create a possibility of having a hyper-connectivity to the environment. It also expects a revolution of traffic management and implements new things to the organization. 5G connections are deployed a network in major cities to reach out in wider areas. 

WLAN technology: WLAN technology is a sort of communication to reduce a physical wire. This network is easy to understand to put in and use the house or different places. WLAN uses two basic technologies to set up a radio transmission device. This connection is a reliable sort of communication and versatile way of communication. The purpose of these services is to allow the employees to a workstation for communication, while maintaining the connectivity uses [6]. This network is to be familiar with the wireless local area network and provide a benefit to the organization. WLAN network is enabled to share data to the external networks to connect a device within the WLAN range. 

Security aspects 

In both the technology 5G and WLAN networks are defined as being wide in the environment. The network deployment models are already run properly in another organization. There are some security aspects are given below: 

5G technology: in the 5G technology one of the most difficult security tasks of 5G network privacy. The enables a security attack as cloud and new data threats merge more devices to the network. Users are stolen and share personal information and collect sensitive data from organizational bodies. 

So, this creates a problem, because more users are connected and devices that can increase the possibility of an attack in cyber securities. In general, 5G system is dependent on five main securities, communication security, identify management, privacy, resilience, and security assurance. Computer security consists of a set of policies and technologies to protect a cloud-based system. 

WLAN technology: WLAN security threats such as unauthorized access, security systems designed to protect a network from security breaches. This type of security has been no physical boundaries and limitations. The resources of network operation create an issue of various authentication, invisibility, and other administration technique.  Wireless local area network is more attacker gains to network data and resources. Where any third parties or entity at the time of computer hijacking then the data being transmitted over the secure network [8]. Even, wired privacy has been ineffective against hackers. WLAN is inherently less protected than cable LAN as the wireless signal is transmitted through the air. A cybercriminal can launch a Man-in-the-Middle attempt and get unauthorized access to a system by abusing the WLAN. Another potential WLAN cybersecurity threat is a denial of service, in which a hacking group can partially or completely shut down the whole system of the organization by making a flood of fake requests. Spam detection and session hijacking are two more major security issues related to wireless networks.

Advantages of wireless technology 

Wireless technology is the most evolving field that is adopted by most business organizations and users. In different aspects, including connectivity, mobility, and accessibility, wireless technology is giving several advantages to the users.

  • Connectivity: In order to efficiently communicate with users and company management, wireless devices and network is now becoming the most useful component [1]. An uninterrupted internet connection and communication could be introduced through the wireless network and devices. 
  • Mobility: Wireless networks and devices are giving an opportunity to the users to work remotely which refers to the improvement in mobility factor. Users can access the internet within the range of the wireless network.
  • Accessibility: This is another essential factor that must be considered during the adoption of wireless components into the network. All the users will be able to access the company data and information from any geographic location by simply giving a username and password into the database. This means, all the networking components and devices are accessible to the users through wireless technology.

Disadvantages of wireless technology 

Apart from different advantages, wireless technology is also responsible for some difficulties that are faced by the users. Therefore, it is essential to consider some disadvantages of wireless technology.

  • Energy loss: Wireless components consume a large amount of power supply that is the primary drawback for this technology [2]. However, the wireless signal is transmitted through a wave and the target devices receive only a little amount of signal. That refers to the energy loss due to the usability of the wireless signal.
  • Eavesdropping: Eavesdropping is a major security concern that is associated with wireless technologies as hackers or external users could get access to the wireless network to steal data or information traveling through the network [3]. This may cause huge losses for the users and the organization any sensitive information is breached by the intruders.
  • Multipath signal noise: Interference of signal is a major issue that could cause due to the multipath signal noise. Here, signal collision happens between the wireless signals coming from different sources to separate destinations. The wireless signals reflect or scatter into the network due to the multipath signal.

The above advantages and disadvantages must be considered by the system designers of the Melbourne Institute of Systems to provide good connectivity and accessibility to their employees and consumers.
