About The High-Performance Wireless Router
High-Performance Wireless Router is a hybrid design product which combines Ethernet
technology and wireless access into a single stand-alone unit. The device allows you
take advantages of both mobility and fast connection. All PCs whenever on wireless
LAN or Ethernet LAN can share files, printers and other network resource. Moreover,
all users can share single account of Internet access by having this device connect to a
DSL/Cable modem.
Ethernet / Fast Ethernet
Ethernet is the most widely-used network access method, especially in a Local Area
Network (LAN) and is defined by the IEEE as the 802.3 standard. Normally, Ethernet is
a shared media LAN. All stations on the segment share the total bandwidth, which
could be 10Mbps (Ethernet), 100Mbps (Fast Ethernet), or 1000Mbps (Gigabit Ethernet).
With a switched Ethernet, each sender and receiver has the full bandwidth.
Fast Ethernet is defined by the as the IEEE 802.3u standard, a high-speed version of
Ethernet with 100Mbps transmission rate.
Wireless LAN
Wireless Local Area Network systems (WLANs) transmit and receive data through the air by using radio
frequency (RF). This offers some advantages like mobility, ease of installation, and scalability over
traditional wired systems.
Mobility: WLANs combine data connectivity with user mobility. This provides users with
access to network anywhere in their organization. For example, users can roam from a
conference room to their office without being disconnected from the LAN. This is impossible
with wired networks.
Ease of Installation: Eliminating the need to deploy network cable in walls and ceilings,
Installing WLANs is easy for novice and expert users alike.
Scalability: WLAN topologies are easy to change in various ways from peer-to-peer networks
for a small group of users to full infrastructure networks for hundreds of users roaming over a
broad area.
Wireless LAN is suitable for difficult-to-wire and frequently changing environments. It’s also an ideal
