Wireless networks

A wireless network allows devices to stay connected to the network but roam untethered to any wires. A device can be located far from a router and yet be connected to the network since access points boost signals.

Types of wireless networks:

Wireless networks can be classified into several types, based on their range and the type of devices they support. Some common types of wireless networks include:

  • Wireless local area networks (WLANs): These networks are used to connect devices within a small geographic area, such as within a home or office. They use Wi-Fi technology to transmit data.
  • Wireless wide area networks (WWANs): These networks are used to connect devices over a larger geographic area, such as a city or region. They use cellular technology to transmit data.

What are the key considerations for deploying a secure wireless network?

Wireless networks provide numerous advantages compared to wired networks, notably heightened mobility and flexibility. With wireless connectivity, users can effortlessly move around their environments without the constraint of physical cables. This feature is particularly beneficial in dynamic workspaces or environments where frequent device relocation is required. Additionally, wireless networks enable the connection of devices in areas where cable installation is impractical or unfeasible, expanding the scope of connectivity in challenging scenarios.

However, it is important to acknowledge that wireless networks are susceptible to interference and security risks, which may impact their performance and reliability. Interference from various sources, such as other wireless devices or physical obstacles, can disrupt signal transmission and cause potential connectivity issues. Moreover, the wireless nature of these networks introduces security vulnerabilities, as unauthorized access and data breaches are possible if adequate security measures are not implemented. Furthermore, while wireless networks have seen significant advancements in speed and reliability, they may still not match the consistent and high-speed performance offered by wired networks in certain situations. Considering these factors, it becomes crucial to carefully assess the requirements and potential limitations when deciding between wired and wireless networks for specific use cases.
