Introduction
The NetComm NP7042 - Wireless LAN USB Adaptor is a Direct-Sequence Spread Spectrum
(DSSS) product. DSSS is a spread spectrum network operating between 2.4 and 2.5 GHz. This
provides a high-capacity network within either large or small environments using multiple access
points.
Based on IEEE 802.11b, Wireless LAN (WLAN) products can perform at speeds of up to 11
Mbps. This technology works by using multiple frequencies in the 2.4 GHz range utilizing
Direct Sequence Spread Spectrum (DSSS) technology.
Designed to cover distances of up to 100 metres indoors and 300 metres outdoors, WLAN
technology lets you access your network from anywhere within this radius. The range of
WLAN is limited by the number of walls, ceilings, floors, or other objects the wireless signals
must pass through. Typical ranges vary depending upon the types of materials and background
radio-frequency in the WLAN area.
WLAN products offer the following network features:
WLAN bridging architecture allows communication between wired network devices and
mobile devices.
WLAN products support the IEEE 802.11b and WiFi specifications. This open architecture
allows WLAN devices to communicate with wireless devices from other manufacturers that
conform to the same specifications.
WLAN products allow mobile devices to roam throughout large facilities while remaining
connected to the network.
WLAN products allow establishment of ad-hoc wireless workgroup networks.
WLAN products are protocol-independent, allowing mobile devices to communicate with a
wide range of servers, hosts and systems.
