Offering Speed and Efficiency

The AG-2000w is a tri-mode, dualband Access Point providing the most expanded
user bandwidth available in an Access Point. Wireless clients can now connect to the
AG-2000w using any one of its 14 non-overlapping channels to transfer data at
speeds never before achievable in a wireless device.
The AG-2000w operates seamlessly and simultaneously in the 2.4 GHz frequency
spectrum supporting the 802.11b and the faster (up to 54 Mbps) 802.11g wireless
standards, while the AG-2000wa also operates in the 5 GHz spectrum supporting the
802.11a wireless standard at speeds up to 54 Mbps—effectively eliminating
interference by other devices that may be operating in the 2.4 GHz frequency range.
Both 802.11a and 802.11g wireless standards utilize OFDM (Orthogonal Frequency
Division Multiplexing) technology. 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, allowing you to transfer large files quickly or even watch a
movie in MPEG format over your network without any noticeable delays.
In addition to its compatibility with 802.11a (AG-2000wa) and 802.11g devices, the
AG-2000w is compatible with 802.11b devices. For HotSpots that already use
802.11b devices, the AG-2000w is the ideal way to expand an existing network,
enabling even more users to communicate with each another, access data and connect
to the Internet.
By offering transfer rates up to 54 Mbps, the AG-2000w enables large data packets to
travel from the router to a remote desktop or roaming laptop PC at up to five times the
speed of previous wireless devices.

Optimizing Performance

Network administrators can partition system usage by segmenting the users on the
wireless network according to frequency band. For example, with the AG-2000wa,
users who require special networking privileges (access to sensitive information,
specific departments or videoconferencing) can use just the 802.11a channels while
other employees use the 802.11b and 802.11g channels. This type of user
segmentation optimizes the product's performance and delivers the best network
experience to all of its users.
