The Covid-19 crisis has increased the need for students to distance learn and workers to telework; however, the digital divide remains as an unbridged connectivity and device gap for many. Devices such as mobile devices, notebook computers must be in place or issued that can connect wirelessly to Wi-Fi for distance learning and teleworking. Some local governments and companies have made progress through publishing online and through physical postings to map these sites. Other local governments may be further ahead in advanced connectivity having deployed wireless connectivity delivery systems that can easily scale to more locations such as parked vehicles with Wi-Fi equipment.

Communications networks are systems of interconnected devices, technologies, and infrastructure that are used to transmit information and data between different points. They can be wired or wireless and can be used for various forms of communication such as voice, text, data, images, and video.

There are several types of communication networks, including:

  • Local Area Networks (LANs): These networks connect devices within a single location, such as an office building or a home.
  • Wide Area Networks (WANs): These networks connect devices across multiple locations, such as a network of offices in different cities or countries.
  • Metropolitan Area Networks (MANs): These networks connect devices within a metropolitan area, such as a city.
  • Cellular networks: These networks provide wireless communication for mobile devices and are the backbone of mobile communication services such as voice and data services.
  • The Internet: The Internet is a global communication network that connects millions of devices and allows for the exchange of information and data on a global scale.
  • Satellite networks: These networks use satellites to provide communication services to remote areas or to ships and airplanes that are in motion.
  • IoT networks: These networks connect devices that are part of the Internet of Things (IoT) such as sensors, appliances, and vehicles.

All these networks rely on a combination of hardware, software, and infrastructure to transmit and receive data. They are essential for modern communication and have become increasingly important in our daily lives, allowing for the exchange of information and data on a global scale. There are three broad technologies in the above. Wired, Wireless and Satalite technologies. They have various benefits and issues:

Wired networks

Benefits:

  • They generally provide faster and more stable connections than wireless networks.
  • They are less susceptible to interference and signal degradation.
  • They are more secure, as it is harder to intercept data transmitted over a wired connection.

Issues:

  • They require physical connections, making them less flexible than wireless networks.
  • They can be more difficult and expensive to install and maintain.
  • They are not portable, and can't be easily moved.
Wireless networks

Benefits:

  • They are more flexible and portable than wired networks.
  • They don't require physical connections, making them easier to set up and maintain.
  • They can provide connectivity in areas where it is difficult or impossible to install wired connections.

Issues:

  • They are generally slower and less stable than wired connections.
  • They are more susceptible to interference and signal degradation.
  • They are less secure than wired networks, as wireless data transmissions can be intercepted more easily.
Satellite networks

Benefits:

  • They provide connectivity in remote and hard-to-reach areas where other forms of communication are not available.
  • They are useful for providing communication services to ships, airplanes and other vehicles in motion.

Issues:

  • They are generally slower and less reliable than wired and wireless networks.
  • They are more expensive to install and maintain than other types of networks.
  • They can be affected by weather conditions and other environmental factors.
  • They have high latency, which means that there is a delay between sending and receiving data.

Ultimately, the choice of network depends on the specific needs and requirements of the application or service. Wired networks are generally best for high-speed and stable connections, wireless networks are best for flexibility and portability, and satellite networks are best for remote and hard-to-reach areas.
