The practice of tagging pavement with codes displaying where Wi-Fi access is available.Click to see full answer. Likewise, people ask, what is Wired Equivalent Privacy WEP is an encryption algorithm designed to protect wireless transmission data?Wired Equivalent Privacy (WEP) is considered as a form of security protocol that was designed in order to provide a level of security and privacy to a wireless local area network (WLAN) comparable to what is normally expected of a wired local area network.Also, what is a means by which portable devices can connect wirelessly? A wireless security protocol to protect Wi-Fi networks. Wireless fidelity (Wi-Fi) A means by which portable devices can connect wirelessly to a local area network, using access points that send and receive data via radio waves. Wireless LAN (WLAN) Similarly, you may ask, what is WIFI infrastructure quizlet? Wi-Fi Infrastructure. includes the inner workings of a Wi-Fi service or utility, including the signal transmitters, towers, or poles, along with additional equipment required to send out a Wi-Fi signal. Hotspots. are designated locations where Wi-Fi access points are publicly available.What are the four wireless communication network categories?Wireless Networks • The four wireless communication network categories are – Personal area networks (PANs) – Wireless local area networks (WLANs) – Wireless metropolitan area networks (WMANs) – Wireless wide area networks (WWANs).
