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 Wireless-N 300 Router Model JWNR2000 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.
