Course Objectives
After successfully completing this course, participants will
develop:
an understanding of what Broadband is
a basic understanding of DSL, DOCSIS (Cable
Modems), FTTx (PON/BPON/EPON), WiFi/WiMAX, and UMTS/HSDPA as
they affect broadband service offerings
a basic understanding of the drivers for
Broadband (Video, Voice, Internet, ‘Killer Apps’,
etc.)
Course Overview
Broadband is the word of the day. High speed,
high capacity, always-on, interactive services are universally regarded
as the future of telecommunications. The potential for broadband
is enormous. A true broadband network is a broadband infrastructure
capable of supporting video, voice and data services and applications
simultaneously over a single physical infrastructure. True broadband
delivers symmetric services at speeds greater than 10 Mbps.
Broadband is high-speed, interactive, always on, two-way communications
provided by cable modems, telephone lines, satellites, fixed and
terrestrial wireless, and fiber optics to the home. Broadband is
not just faster Internet. Broadband is more appropriately defined
as a connection platform, a gateway to information and services.
It can be accessed from a home computer, a wireless handheld device
and soon even accessed by household appliances. In fact, broadband
is whatever the user wants it to be.
Broadband infrastructure has many different technologies that create
it that Wireline and Wireless Carriers, as well as Country Regulators,
must consider. Without proper consideration of the technologies
and deployment requirements, broadband expenditures represents a
major risk to the Carriers – because many times, it is ‘hype’
driven instead of driven by business requirements complimented by
technology with a strong focus on customer requirements and Governmental
regulations.
This course will introduce the respective broadband serving technologies
and review some of the deployment methodologies for such technologies.

Module Two: DSL
With the tremendous growth experienced by the Internet, and with
an increase in teleworking, there is a need to exploit the bandwidth
potential of the local copper loop. xDSL is partially responsible
for the massive expansion of ‘Broadband.’ xDSL uses
existing twisted pair technologies lines to transmit data at a
range of speeds, whilst supporting multiple media formats.

Module Three: IP DOCSIS (Cable Modems)
DOCSIS (Data Over Cable Service Interface Specifications) is a set
of standards produced by the Cable Television industry for delivering
Internet access and other data services over traditional cable television
networks. It has evolved from version 1 with version 2 being the current
standard. Version 3 offers the Cable Industry the ability to produce
bonded services to customers at speeds in excess of 100 Mbit/s.
This course module provides a basic understanding of how modern installed
Cable systems work today, how they have evolved from analogue into
digital services using DOCSIS and Euro-DOCSIS 1.0/2.0.

Module Six: UMTS/HDSPA
HSDPA, short for High-Speed Downlink Packet Access, is a
new protocol for mobile telephone data transmission. It is
known as a 3.5G (G stands for generation) technology. Essentially,
the standard will provide download speeds on a mobile phone
equivalent to an ADSL (Asymmetric Digital Subscriber Line)
line in a home, removing any limitations placed on the use
of your phone by a slow connection. It is an evolution and
improvement on W-CDMA, or Wideband Code Division Multiple
Access, a 3G protocol. HSDPA improves the data transfer rate
by a factor of at least five over W-CDMA. HSDPA can achieve
theoretical data transmission speeds of 8-10 Mbps (megabits
per second). Though any data can be transmitted, applications
with high data demands such as video and streaming music are
the focus of HSDPA.
HSDPA improves on W-CDMA by using different techniques for
modulation and coding. It creates a new channel within W-CDMA
called HS-DSCH, or high-speed downlink shared channel. That
channel performs differently than other channels and allows
for faster downlink speeds. It is important to note that the
channel is only used for downlink. That means that data is
sent from the source to the phone. It isn't possible to send
data from the phone to a source using HSDPA. The channel is
shared between all users which lets the radio signals to be
used most effectively for the fastest downloads.
