Wireless communication is the transmission of signals using radio waves as the medium instead of wires. This simple concept has unlocked a world of connection and convenience by freeing us from physical tethers. The primary benefits of this freedom are clear in our daily lives:

• Mobility Allows users to access information and conduct business from anywhere without needing a physical wire.
• Reachability Enables people to stay connected and be reachable, regardless of the location from which they are operating.
• Simplicity Wireless networks are often easier and faster to deploy in comparison to traditional cabled networks.
• Maintainability Wireless network setups typically require less cost and time to maintain compared to wired infrastructures.
• Roaming Services Allows for the provisioning of network services anywhere and anytime, including on trains, buses, and airplanes.
• New Services Opens the door for various smart services, such as the delivery of SMS and MMS messages.

While the concept of “no wires” is straightforward, wireless networks can be set up in several different ways to meet specific needs.
