Wireless products are based on industry standards designed to provide easy-to-use and compatible high-speed wireless
connectivity within your home, business or public access wireless networks. Strictly adhering to the IEEE standard, Samsung
the wireless family of products will allow you to access the data you want securely, when and where you want it. You will be
able to enjoy the freedom that wireless networking delivers.
A wireless local area network (WLAN) is a cellular computer network that transmits and receives data with radio signals in-
stead of wires. Wireless LANs are used increasingly in both home and office environments, and public areas such as airports,
coffee shops and universities. Innovative ways to utilize WLAN technology are helping people to work and communicate more
efficiently. Increased mobility and the absence of cabling and other fixed infrastructure have proven to be beneficial for many
users.
Wireless users can use the same applications they use on a wired network. Wireless adapter cards used on laptop and desk-
top systems support the same protocols as Ethernet adapter cards.
Under many circumstances, it is desirable for mobile network devices to link to a conventional Ethernet LAN to use servers,
printers or an Internet connection supplied through the wired LAN. Samsung's Wireless Router provides this link.
What is Wireless?
Wireless or Wi-Fi technology is another way of connecting your computer to the network without using wires. Wi-Fi uses ra-
dio frequency to connect wirelessly, so you have the freedom to connect computers anywhere in your home or office network.
How does Wireless work?
Wireless networking works much the same way as cordless phone work, through radio signals that transmit data from one
point A to point B. But wireless technology has restrictions which limit how you can access the network. You must be within
the wireless network's range to be able to connect your computer.
Wireless Local Area Network (WLAN)
There are two different types of wireless networks: Wireless Local Area Network (WLAN), and Wireless Personal Area Network
(WPAN).
In a wireless local area network, a device called an Access Point (AP) connects computers to the network. The access point
has a small antenna attached to it, which allows it to transmit data back and forth using radio signals. With an indoor access
point, the signal can travel up to 300 feet. With an outdoor access point, the signal can reach out up to 30 miles and serve
places such as manufacturing plants, industrial locations, college and high school campuses, airports, golf courses, and
many other outdoor venues.
Wireless Personal Area Network (WPAN)
Bluetooth is the industry standard wireless technology used for WPAN. Bluetooth devices in WPANs have a range of up to
30 feet. Compared to WLAN, the speed and wireless operation range are less, but in return, Bluetooth doesn't use nearly as
much power which makes it ideal for personal devices, such as mobile phones, PDAs, headphones, laptops, speakers, and
other devices that operate on batteries.
Who uses wireless?
Wireless technology has become so popular in recent years that almost everyone is using it. Whether it's for home, office,
business, Samsung has a wireless solution for it.
