Question by : Data Communications: parameters for different broadband internet access techniques, please help?
I got an assignment on my data communications course, and I really can?t figure out what my lecturer means. The exact text he wrote as the assignment is as follows:
?Using our course documentation, and available information on the
Internet, answer the following questions:
During the past few years, broadband Internet access to private homes
has been offered using several different broadband technologies, such
as cable TV, ISDN, ADSL, VDSL, Wireless Broadband, Satellite links, 3G
and 4G networks, etc.
Using the textbook and the Internet, research and compare the
following technical parameters for five (5), or more, broadband
Internet access technologies:
- modulation
- compression
- datarate
- reliability (bit errors ? BER)
I suggest you document this in table format, such as in MS Excel.
Tip: Find out which companies manufacture modem chips for the
different technologies, and download their technical specifications.
More information can be obtained from the International
Standardization documents, as well as from scientific articles. You
can even search Wikipedia for ADSL, etc?
With only a first look at it, it seemed to be a rather easy tast, but I?ve been searching the web for like two days without any luck, and the assignment is due tomorrow. The bit rates are obviously not the tricky part. We haven?t started reading about any modulation techiques yet, nor any compression techniques, so I don?t even know if the answer he wants should be displayed as a value in some unit or if the answer is some name for a standard or protocol.
Please help me out here!
