Wireless technologies generally require less infrastructure, but can be more expensive to use than cable-based technologies. Some examples are radio, microwave and satellite wireless telephony, or use of ‘bluetooth’ technology in mobile phones and computers.
Detailed Explanation
Wireless technologies allow for communication without the need for physical connections like cables or wires. Instead, they use radio waves to transmit data over the air. This can be more convenient and versatile, especially in locations where it may be difficult to lay down wires. However, the costs involved in deploying these technologies can be higher compared to traditional wired systems.
Examples & Analogies
Consider how your smartphone connects to the internet. Instead of needing a cable to plug into your wall outlet for internet access, your phone uses wireless technology to connect to your home Wi-Fi or cellular network. This ability to stay connected on the go is a direct benefit of wireless technology.

Two significant communication technologies that acted as media and changed the whole communication scenario are the radio and the television.
Detailed Explanation
Radio and television have dramatically shaped how information is disseminated to the public. Radio allows for the broadcast of news and entertainment to vast audiences without the need for visual interaction. Television adds a visual element, enhancing the way stories and messages are delivered. Both have reached audiences in remote areas and transformed communication by overcoming geographical barriers.
Examples & Analogies
Think about how you might listen to the news on the radio while driving. It keeps you informed without requiring you to stop and read something. Similarly, when you watch a show on TV, you see visuals that bring the content to life—like a cooking show where you can not only hear the recipe but also see how it's done. This combination makes it easier to understand and remember the information.

Modern Communication Technologies include radio, mobile phones, video conferencing, Bluetooth technology, and even satellite communication.
Detailed Explanation
There’s a wide range of devices that utilize wireless communication technology. Radios broadcast audio signals through the air, while mobile phones enable personal communication via voice and text. Video conferencing software allows people to meet online using their cameras and microphones, bypassing the need for travel. Bluetooth connects devices wirelessly for short-range data transfers like connecting headphones to a smartphone.
Examples & Analogies
Imagine you are attending a family gathering, and everyone is sharing their phones via Bluetooth to send photos. Each device connects wirelessly without any fuss or messy wires, allowing immediate sharing of memories from the event. Similarly, during business meetings, video conferencing allows teams to collaborate without being in the same room, making global teamwork seamless.
