D-Link Systems, Inc.
D-Link
wireless products are based on industry standards to provide easy-to-use and compatible high-speed
wireless connectivity within your home, business or public access wireless networks. D-Link wireless products
will allow you access to the data you want, when and where you want it. You will be able to enjoy the freedom
that wireless networking brings.
A Wireless Local Area Network (WLAN) is a computer network that transmits and receives data with radio
signals instead of wires. WLANs 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 desktop systems support the same protocols as Ethernet adapter cards.
People use WLAN technology for many different purposes:
Mobility
- Productivity increases when people have access to data in any location within the operating
range of the WLAN. Management decisions based on real-time information can significantly improve worker
efficiency.
Low Implementation Costs
- WLANs are easy to set up, manage, change and relocate. Networks that
frequently change can benefit from WLANs ease of implementation. WLANs can operate in locations where
installation of wiring may be impractical.
Installation and Network Expansion
- Installing a WLAN system can be fast and easy and can eliminate
the need to pull cable through walls and ceilings. Wireless technology allows the network to go where wires
cannot go - even outside the home or office.
Inexpensive Solution
- Wireless network devices are as competitively priced as conventional Ethernet
network devices. The DVG-G1402S saves money by providing multi-functionality, configurable in one of four
different modes.
Scalability
- WLANs can be configured in a variety of ways to meet the needs of specific applications and
installations. Configurations are easily changed and range from Peer-to-Peer networks suitable for a small
number of users to larger Infrastructure networks to accommodate hundreds or thousands of users, depending
on the number of wireless devices deployed.
Standards-based Technology
The DVG-G1402S Wireless Gaming Adapter utilizes the
802.11b
and the
802.11g
standards.
The IEEE
802.11g
standard is an extension of the
802.11b
standard. It increases the data rate up to 54Mbps
(108Mbps in Super G mode) within the 2.4GHz band, utilizing
OFDM technology.
This means that in most environments, within the specified range of this device, you will be able to transfer
large files quickly or even watch a movie in MPEG format over your network without noticeable delays. This
technology works by transmitting high-speed digital data over a radio wave utilizing
OFDM
(

OFDM
works by splitting the radio signal into multiple smaller
sub-signals that are then transmitted simultaneously at different frequencies to the receiver.
OFDM
reduces
the amount of
crosstalk
(interference) in signal transmissions. The D-Link DVG-G1402S will automatically
sense the best possible connection speed to ensure the greatest speed and range possible.
