Overview Of Home And Small Office Networking Technologies - NETGEAR RangeMax WNR834B User Manual

Figure 6-6 shows an example network using multiple networking technologies. In this network,
the two PCs with gigabit (1000 Mbps) Ethernet adapters have a gigabit connection through the
GS605 switch to the storage server. This connection should allow for extremely fast backups or
quick access to large files on the server. The PC connected through a pair of Powerline HD
adapters is limited to the 200 Mbps speed of the Powerline HD connection. Although any of the
links in this example would be sufficient for high-traffic applications such as streaming HD video,
the use of older devices such as 10 Mbps Ethernet or 802.11b wireless would create a significant
bottleneck.
Overview of Home and Small Office Networking
Technologies
Common connection types and their speed and security considerations are:
• Broadband Internet
Your Internet connection speed is determined by your modem type, such as ADSL or cable
modem, as well as the connection speed of the sites to which you connect, and general Internet
traffic. ADSL and cable modem connections are asymmetrical, meaning they have a lower
data rate to the Internet (upstream) than from the Internet (downstream). Keep in mind that
when you connect to someone else who also has an asymmetrical connection, the data rate
between your sites is limited by each side's upstream data rate. A typical residential ADSL or
cablemodem connection provides a downstream throughput of about one to three megabits per
second (Mbps). Newer technologies such as ADSL2+ and Fiber to the Home (FTTH) will
increase the connection speed to tens of Mbps.
• Wireless
Your RangeMax NEXT Wireless Router WNR834B provides a wireless data throughput of up
to 300 Mbps using technology called Multiple-Input Multiple-Output (MIMO), in which
multiple antennas transmit multiple streams of data. The use of multiple antennas also
provides excellent range and coverage. With the introduction of the newer WPA and WPA2
encryption and authentication protocols, wireless security is extremely strong.
To get the best performance, use RangeMax NEXT adapters such as the WN511B for your
computers. Although the RangeMax NEXT router is compatible with older 802.11b and
802.11g adapters, the use of these older wireless technologies in your network can result in
lower throughput overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for
802.11g). In addition, many older wireless products do not support the latest security
protocols, WPA and WPA2.
