Public WiFi is convenient but not safe as hackers can steal personal information. Use a firewall, avoid conducting private business, shopping, and online banking, disconnect all networked computers, and turn off wireless when not in use. Public WiFi® is everywhere you go, like in coffee shops, libraries, print shops and even some fast food restaurants. […]
Arduino boards do not have WiFi, so WiFi capabilities are added by combining a standard board with a WiFi shield. WiFi Arduino devices allow for wireless input and reprogramming from multiple computers, creating simple websites, and transmitting data faster than other interfaces. However, WiFi is more expensive and consumes more energy, so it is not […]
Arduino boards do not have WiFi capabilities, but can be combined with a WiFi shield. Advantages include wireless input and multiple user interaction, creating simple websites, and transmitting data quickly. However, WiFi is expensive and consumes more energy, making it less common than other interfaces. An Arduino® WiFi® is an Arduino® board that has the […]
A WiFi home network uses Wi-Fi technology and is easy to set up. The heart of the network is the router, which connects to the internet and allows devices to connect wirelessly. Devices must be certified to the Wi-Fi standard and can include computers, printers, and phones. Security measures, such as a passcode, can be […]
WiFi sniffers detect available wireless networks before booting up a computer. They come as stand-alone devices or add-on software for portable devices. Some companies ban random scanning applications in favor of directory-based ones. WiFi sniffer reviews are available online. WiFi sniffers have practical applications but also raise privacy concerns. They can identify areas with the […]
WiFi sniffers detect available wireless networks before booting up a computer. They are available as stand-alone devices and add-on software for portable devices. Some companies have banned random scanning software in favor of directory-based applications. Reviews of WiFi sniffers are available online. WiFi sniffers have been used for controversial purposes, such as Google Maps Street […]
Wireless sniffers capture and save data packets on wireless LAN channels, useful for network troubleshooting and security. However, hackers can exploit them for malicious purposes, stealing confidential and personal information. Adequate security protocols and encryption can prevent misuse. The term sniffing, as it relates to the Internet, is the process of intercepting data traffic as […]
A WLAN modem allows computers to communicate wirelessly and share an internet connection. It has a built-in router and requires a wireless network card to connect. Standards are set by IEEE and certified by Wi-Fi Alliance. Mobile modems use cellular technology. Compatibility with existing devices should be considered when purchasing. A wireless local area network […]
A WLAN modem allows computers to communicate wirelessly and share an internet connection. It has a built-in router and requires a wireless network card to connect to computers. The Wi-Fi Alliance certifies products for interoperability, and the IEEE establishes wireless communication protocols. Mobile wireless modems provide internet access on the go. When purchasing a WLAN […]
A Wi-Fi monitor detects local wireless networks, providing detailed information and traffic data. It can be useful for locating hotspots and is available as software or gadgets. The software expands on the operating system’s functionality, displaying signal strength and network speed. Additional features include saving favorite networks and creating a priority list. Standalone gadgets detect […]
Free WiFi hot spots are available in public places like coffee shops, restaurants, and libraries. Two types of networks are used: unsecured public networks and closed public networks that require login credentials. Closed networks offer more security and allow owners to limit bandwidth per user. Offering free WiFi can increase revenue for businesses and provide […]
Wi-Fi Direct allows Wi-Fi CERTIFIED devices to connect without a router. It operates at distances up to 656 feet and can join devices 1:1 or one to many. It is not intended to replace WLANs but facilitate sharing between devices. It can optionally join a traditional WLAN to provide a shared internet connection. The most […]
WiFi is the 802.11 wireless standard used for localized connections, limited to around 300 feet. WiMAX is the 802.16 standard with a range of up to 2,800 square miles, while WiBro is similar to WiMAX but can track a receiver as it moves. While almost any type of wireless network may seem confusing, there are […]
WiFi, WiMAX, and WiBro are wireless standards for connecting to networks. WiFi is limited by range, while WiMAX can cover up to 2,800 square miles. WiBro is similar to WiMAX but can track a receiver as it moves. WiBro is still under development. While almost any type of wireless network may seem confusing, there are […]
Wireless internet requires a sender and receiver, typically set up through a home network with a router. The signal degrades quickly and distance affects reliability. A wireless access card can be used for mobile users, but requires a separate service subscription. Wireless Internet access depends on two main components, a sender and a receiver, both […]
WiFi sniffing is the act of discovering the location or activity on a WiFi network, which can be done for legitimate or malicious purposes. WiFi is a wireless standard based on IEEE 802.11. Sniffing packets refers to monitoring activity on a network and can be used by network administrators or thieves. To protect against WiFi […]
Wardriving WiFi involves driving around to locate wireless networks using a laptop, phone or gaming system. It can be legal but may be invasive and piggybacking on networks can be illegal. Similar practices include warbiking and warwalking. Wardriving WiFi® is a process by which a person physically drives around an area trying to locate wireless […]
Wi-Fi Protected Access (WPA) uses encryption and authentication protocols to prevent unauthorized users from accessing wireless connections. It is commonly used in corporate and residential settings to restrict access to authorized devices. WPA eliminates the potential for unauthorized access and allows for temporary access to visitors with security codes. Wi-Fi Protected Access is a strategy […]
WiFi hotspots provide wireless Internet access for devices such as laptops and phones. They are found in various businesses and public areas, and can be free or require payment. The idea was proposed in 1993 and has since become widespread, with many cities offering WiFi services. Users can access open or closed networks to browse […]
