NetComm NP7042 manual Introduction

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.
