 |
Feature |
 | |
|
| |
| The GW-NS54GM,
a CardBus-type 54Mbps Wireless LAN Adapter fully
complies with IEEE802.11g standard. The product supports
64bit/128bit WEP encryption, as well as the latest
wireless security standard - WPA (Wi-Fi Protected
Access), thus enables the implementation of a truly
secure wireless LAN environment. |
| |
 |
Ultra fast data communication
at a maximum speed of 54Mbps |
| |
As the product supports IEEE802.11g, it enables high
speed data communication at a maximum rate of 54Mbps
while it utilizes the same 2.4GHz frequency range used
by IEEE802.11b. The adapter thus achieves superb data
transfer performance for both sending and receiving
voice, video and other types of high volume data. |
|
Intercommunication with existing wireless
LAN |
| |
The product is capable of intercommunicating with
products supporting IEEE802.11b, the most widely used
wireless LAN standard today. The LAN adapter enables
easy upgrade to faster data communication environment
while allowing its user to fully utilize the existing
wireless LAN system. |
|
Wi-Fi certified
|
| |
The GW-NS54GM is Wi-Fi certified in the IEEE802.11b
data transfer mode. The Wi-Fi certification serves as a
guarantee of interoperability between wireless devices
from different vendors. |
|
Supports outdoor usage
|
| |
The product can be used outdoors as it utilizes the
2.4GHz frequency range. Furthermore, it requires no
licensing application as the adapter complies with ARIB
STD-T66 (Low Power Data Communication System standard).
|
|
Highly sensitive Diversity
Antenna |
| |
The integrated diversity antenna maintains high
quality data transfer during wireless communication.
|
|
Supports Roaming
|
| |
The product supports Roaming, an advanced technology
which automatically selects (and connects to) the most
appropriate access point while the user remains online
and moves between multiple AP's. This way, the adapter
achieves a seamless wireless LAN environment. |
|
Supports multiple
communication modes |
| |
In addition to Ad Hoc mode (802.11 Ad Hoc) for
direct wireless communication between wireless devices,
the product supports Infrastructure mode in which
wireless communication is performed via access points
(AP). |
|
Robust security
features |
| |
The product utilizes 64/128bit WEP (Wired Equivalent
Privacy) to encrypt communication data, making it
impossible to decipher should someone intercept the data
by any chance. |

| Since no cabling is required to set up a wireless
LAN, virtually anyone can establish and start using a
wireless LAN with ease. However, data communication
between two nodes may fail or slow down significantly if
they are separated by any of the following materials
(see below). To ensure stable data communication, it is
strongly recommended to remove these objects or
environmental factors from the installation site. |
