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 another site that 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 cable modem connection provides a downstream
throughput of about 1 to 3 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 N300 WiFi Router (N300R) 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.
