They are those accesses that do not require a wired connection to the user's terminal, since the communication occurs wirelessly through electromagnetic waves, but that require the user to be at a distance from the access point not greater than the reach thereof.
This type of access usually supplements or complements wired access, replacing the last stretch of cable that connects the user terminal to the network, with a wireless link, as happens in home Wi-Fi networks. These accesses, although they give some mobility to the user, it is not total, since it is limited to a specific area that depends on the coverage of the wireless access point. It should be noted that, despite the speeds allowed by each wireless access technology, the actual speed of Internet access will depend on the speed that is contracted with the Internet access service provider.
Among the technologies of this type are:
WiFi
Wi-Fi technology allows communication between devices wirelessly via electromagnetic waves. Due to its ease of installation and operation it has become one of the most popular wireless technologies, and is widely used in home networks, replacing the wired connection from the user terminal to the router or modem that gives access to the Internet.

WiMAX
WiMax is a technology that, like Wi-Fi, allows wireless communication between devices through electromagnetic waves. WiMax offers similar performance to Wi-Fi, but allows for greater coverage and quality of service, achieving a theoretical range of up to 50 Km for wireless access from a fixed location and around 15 Km for mobility access.

Satellite
Satellite communications are also based on wireless technologies, and serve for the provision of both telephone and television services and broadband Internet access. The main advantage of broadband satellite access is that it provides virtually universal coverage, however, the speed of connections can be limited by different factors.
