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
A high-speed wireless router can provide 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 newer adapters such as RangeMax adapters for your
computers. A high-speed router might be compatible with older 802.11b and 802.11g adapters,
but 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.
• Powerline
For connecting rooms or floors that are blocked by obstructions or are distant vertically,
consider networking over your building’s AC wiring. NETGEAR’s Powerline HD family of
products delivers up to 200 Mbps to any outlet, while the older generation XE family of
products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for security, and you
can configure an individual network password to prevent neighbors from connecting.
