Wireless Local Area Networks (WLANs)

Since recently, there has been a growing global trend of using various wireless devices everywhere. Present-day laptops, tablets, mobile phones boast significant computing capabilities and can in many ways replace desktops computers and increase their users' mobility. For this reason, one of the most topical areas in the IT infrastructure development is wireless local area networks that transmit data via radio channels and do not use wires.

Wireless transmission technologies make it possible to supplement a classical wired corporate network by using mobile equipment in addition to fixed hardware.

Moreover, it becomes possible to do without designing and mounting bulky cable systems and significantly reduce the expenses related to the network infrastructure construction.

Use case:

  • Organizing a high-speed connection of mobile wireless devices to the corporate network infrastructure
  • Base environment for IoT (Internet of Things)
  • High-precision indoor navigation, Wi-Fi analytics
  • It becomes possible to completely replace a traditional wired network, if building a network requires high mounting costs
  • Establishing a network connection to a remote or hard-to-reach network segment;
  • An option to use employees' personal mobile devices to access corporate IT services using the BYOD (Bring Your Own Device) technology

Subsystem elements:

Depending on the applicable requirements and tasks, a wireless local area networks typically consist of three types of devices:

  • Wireless network adapter: a hardware component of mobile devices that implements the wireless data transfer technology. As a rule, all present-day devices have built-in network adapters. However, a standalone adapter may be required to connect desktop computers to a wireless network.
  • Wireless network access point: this device is a base station for wireless access of mobile clients to existing network infrastructure. Wireless access points have a port for connecting to wireless networks making it possible to connect them to wired switches and combine wired and wireless networks within a single network infrastructure. In addition, access points can be equipped with several antenna types for a range of tasks when creating a network—from connecting a large number of nearby wireless end devices to establishing connection between two access points located at a long distance from each another.
  • Wireless network controller makes it possible to automate the process of wireless network infrastructure management. In addition, the controller ensures network security, monitors it, and distributes load between access points for centralized management of the wireless network.

Benefits of the subsystem:

  • High-speed access to the corporate network for mobile users
  • Quick and efficient deployment
  • Lower network infrastructure development costs—no need to install structured cable systems
  • High mobility, scalability, and throughput capability
  • An option to provide secure wireless network access to guests and business partners
