This wireless networking FAQ addresses common concerns about wireless networks. Learn the differences between wireless and wired networks and get an overview of the equipment you'll need for a wireless network from these frequently asked questions (FAQ).
The next generation of the Wi-Fi standard is Wi-Fi 6, also known as 802.11ax, the latest step in a journey of nonstop innovation.
It will let access points support more clients in dense environments and will provide a better experience for typical wireless LAN networks. It will also provide a more predictable performance for advanced applications such as 4K or 8K video, high-density high-definition collaboration apps, all-wireless offices, and the Internet of Things (IoT). Wi-Fi 6 will drive Wi-Fi toward the future as the growth of wireless continues. See our technical white paper: IEEE 802.11ax: The Sixth Generation of Wi-Fi.
A wireless local-area network (WLAN) uses radio waves to connect devices, such as laptops, to the Internet and to your business network and applications.
A wireless router or access point's signal typically extends up to approximately 300 feet.
A wired network connects devices to the Internet or other networks using cables. Some believed wired networks were faster and more secure than WLANs. But continual enhancements to WLAN standards and technologies have largely erased those differences.
WLANs are frequently offered in public places such as cafes, hotels, and airport lounges. In addition, many businesses have wireless networks throughout their office buildings or campuses for employee and guest use.
Many routers act as WLAN access points. They connect multiple computers (and wireless-capable printers) to a single WLAN and to the Internet.
You can extend WLANs throughout an area by placing additional wireless access points in various locations. The access points extend the wireless signal's range and strength.
Most laptops have built-in wireless networking. If yours doesn't, you'll need a wireless network adapter card, which is typically inexpensive and easy to install.
There are many ways to secure your WLAN, including:
Small businesses can experience many benefits from a WLAN. A few examples:
