The L4L Project
“If high school teachers are of the
opinion that the Laptops4Learning
program is a waste of money and won’t
work, then it probably won’t work.
But the money is being spent anyway.”

The L4L Project is Cutting-Edge
• NSW DET is not cutting any corners with
the technical aspects of this project
– The Laptop chosen is highly spec’ed
– Latest O/S and professional software
– The wireless provided is the best, fastest
and most manageable solution available
– On-line services are being developed to
provide students and staff with secure data
storage and collaborative applications

•
Windows 7 Release Candidate
•
Lots of educational freeware
Why Windows 7 RC?
• Everybody originally assumed Linux
• Then Windows XP took over the Netbook
market by massively dropping its price
• But with the release of Windows 7 RC in
May 09, it was evident that this was the
best (fastest, most powerful) operating
system for Netbooks and for L4L
• Netbooks will be replaced with Windows
7 when it is released later this year
NSW Department of Education & Training

www.sydneyr.det.nsw.edu.au
Why Windows 7 RC?
• Windows 7 RC provides backwardcompatibility with most existing XP software
• NSW DET has a massive knowledge
investment in Windows in both the server
(technical) and client (user) arenas
• Windows 7 represents the latest in
operating systems as compared to Win XP
which is now 7 years old (end of life)
• Vista was never in the picture

What you can’t do with the laptops
(…that you were hoping you could)
• Every High School in NSW seems to be doing things
differently with ICTs due to a history of autonomy
• It is this autonomy that has forced NSW DET to come
up with a unique and supportable solution for L4L
• We need ONE revolution, not hundreds of them. So:
• Local administrator access will not be provided for the laptops
• Additional software that requires admin access to install can’t be
installed on the laptops
• The Laptops will not be joined to the school’s Windows domain
• The Laptops won’t be shipped with a Netware Client for Novell servers
• Group Policies/Scripts delivered from your server won’t be applied
• Printing to some of the school’s printers may not be possible
NSW Department of Education & Training

Supporting the Laptops
• The solution being adopted relieves the
need for the school’s CC to try to make
hundreds of new laptops “fit” with their
existing school network
• L4L is a statewide project – NOT a school
project
• If your school is thinking of wiping the
image to create its own, forget it.
• Support is provided, take it. You’ll need it.

What the Laptops can do…
• Authenticate to Windows using the DET Portal ID – one laptop,
one user only (Allocated mode)
• Connect to the school’s new wireless network providing
access to Internet, DET intranet and the school’s web services
• Print to selected HP networked laser printers via IP printing
(drivers supplied)
• Run the pre-installed applications
• Provide a virtual 1024x768 display (scrolls down a little)
• Connect wired or wirelessly at home / wirelessly at McDonalds
• Accept a USB flash or hard disk to read from/write to.
• Connect via Remote Desktop to well-configured and spec’ed
school terminal servers

Spare Pool of Laptops
• L4L computers for year 9 Students are
ALLOCATED – one PC, one user ONLY
• Spare L4L computers (from Pool) can be:
– LOANED (long term or short term) – these are the
same as Allocated, but they are expected to be
returned. Must be reimaged upon return. Can be
Loaned to Students (10-12) and/or Staff
– POOLED – used by multiple users, in the library or
classrooms
• All allocations of laptops via RMU – managed by
the in-school L4L support officer

L4L: Managing the Laptops
• L4L Device Manager
(aka the L4L Support Officer’s toolbox):
– Single point of admin
– Integration with existing infrastructure :
– IDM, AD, Portal, ERN, SMU, EMU, Remedy,
Computrace
– Device, Student and Staff Management
– Each device will have a current state.

L4L: Managing the Laptops
• Device State(s) :
– Inaugural (still in shrink wrap, delivered by Lenovo)
– Allocated (in 2009 to a year 9 student) – It’s their machine, no
other student can logon to it
– Loaned – Teacher machine or temporary assignment to a student
– Pool (either in storage or general usage)
– Broken, Stolen or Lost – In an interim state of inoperability
– Retired (Broken, Stolen or Lost) – Permanently written off
• Computrace tracks ‘atomic’ activity, assist
in recovery and denial of stolen devices.

L4L – The Wireless Solution
• Preliminary designs and installations are
happening RIGHT NOW
• Schools must nominate up to 12 Learning
Spaces in addition to the Library for wireless
installation in Phase 1 (max. 3 buildings)
• The Wireless network is TOTALLY separate to
the school’s existing wired and wireless LAN
• Spare Fibre is REQUIRED between the
Campus Distributor and all Building Distributors
NSW Department of Education & Training

L4L – Wireless Phase 1
• Phase 1 Installation covers:

Wireless Mobility Controller
2 Wireless Access Points (WAPs) in Library
Up to 12 WAPs in Learning Spaces in up to 3 buildings
Up to 3 cabinets with 3 POE Edge switches
“DIP” server and UPS (supplied before Phase 2)
Design of Phase 2 installation requirements

L4L – Wireless Phase 2
• Phase 2 Installation covers:
– One WAP in each Learning Space (as defined by AMS)
– Sufficient cabinets plus POE switches as required
– Installation in “eligible” demountables (demountables
are normally excluded from the project)
– Requested and approved staffroom installations
• Phase 1 Completion by start of Term 3 2009
• Phase 2 Completion by start of Term 1 2010

L4L – The Wireless Solution
• The new wireless system is based upon the
802.11n draft 2 standard and configured
to operate in the 5 GHz range
• Existing 802.11a wireless will cause conflicts
• The 2.4 GHz range will only be used to
monitor the air, existing b/g wireless can stay
• N and WPA2 + AES (Advanced Encryption
Standard) must be configured on all 3rd-party devices
• The SSID will be set to NSWDET
NSW Department of Education & Training
Sydney Region
NSW Public Schools – Leading the Way
www.sydneyr.det.nsw.edu.au
L4L – The Wireless Solution
• 802.11N will provide an absolute minimum of 2Mbit/s
with 30 laptops connected to a single Wireless Access
Point in a room
• Theoretically, under ideal conditions, 30 laptops
should be able to achieve 5-8 MBit/s access.
• Other “N” devices may be able to connect for webbased Internet and Intranet access only
• A/B/G devices will NOT be able to connect
• All learning spaces (in AMS) will get an Access Point
by the end of Phase 2 (mid 2010)

Your Campus Distributor
Fibre backbones with spare pairs required!
NOTE: Investigate your backbones and all of
your BDs! If they are copper or you have no
spare fibre pairs, you have a problem which
will delay the completion of your WLAN install
