(Mon - Fri) 5-day Instructor-led training, 0900 - 1700 Singapore, Singapore
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

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.
