1. OVERVIEW
1.1 ABOUT ADSL
An ADSL MODEM is a broadband Internet access devicewhich utilizes the high frequency segment of the
phone line to transmit high-speed data without affecting the voice transmission. The frequency of the ADSL signal
is higher than that of voice, so voice and ADSL signal can coexist in one line by using a splitter to insulate each
from the other. ADSL data transfer adapts the asymmetry model. It supports upload transmission speed up to
1Mbps and download speed up to 8 Mbps. ADSL is an ideal device for broadband access.
But the ADSL users are also limited by the wire and can’t move freely. DB108-WL wireless ADSL Modem is
a new device that integrates WLAN and ADSL functions. Users can slip the leash to visit Internet even in moving
as long as they install WLAN cards into their computers. DB108-WL can be utilized in companies, hotels, cafés,
airports, stations, financial institution and personal homes where there are many mobile users and the network
infrastructures are difficult to establish. The wireless data rate varies among 1, 2, 5.5 and 11Mbps.
