6. Internet Access
The number of options for schools to be connected
to the Internet depends on where the location of the school
are. In larger cities/towns you have access to the web via
xDSL, cable, ISDN, satellite as well as the standard modem.
With schools now demanding increased access speeds the humble
modem is beginning to be phased out and replaced by these
other options.
The relative speeds of each of these options is outlined
below:
|
Modem connection ** (56Kbs) |
|
ISDN *** (two channels of 64Kbs) |
|
Cable ***** (512Kbs or 2Mbs with cable modem) |
|
xDSL ***** (up to 6Mbps within 3-5km of exchange)
|
|
Satellite *** (up to 3Mbps download only) |
If
you are going to use anything other than a modem you will
require a router to "route" data to the computer
that has requested it. A router costs between RM600-RM3000
for school systems. Ensure that the router has sufficient
bandwidth for your needs and your expected needs once you
have high speed internet access.
The problem with high speed internet access
is cost. Because you can download a 5Mb file you tend to
do, as do the students. It is imperative that staff and
students are aware of the true cost of downloading a 5Mb
file and that limits are put in place. In large primary
schools/small secondary schools/colleges, 300Mb/month seems
to be becoming a standard. This is not sufficient of course,
but with the following systems in place you will be able
to manage!
The options for internet access are considerable.
Schools are beginning to publish data in greater volumes
to the internet so we will see a transition towards the
requirement for higher speed and greater bandwidth, both
into and from the school.
Transmission which limits outward traffic,
such as one way satellite services may no longer be suitable
and a strategy will need to be in place to make sure this
does not become a bottleneck for the school. Other options
include cable, xDSL or ISDN rated systems.
You can reduce the amount of access required
to the internet by "whacking"; copying web sites
onto the file server. This is achieved using "off-line
browser" software which is very cheap and easy to use.
By copying web sites onto the file server the site will
be there when you need it and it will arrive instantly!
However, by copying someone's web site you
are breaking copyright. You MUST e-mail the site owner and
ask permission to do this. State the time you wish to copy
the site for, and do not try and copy databases, search
engines or extremely large sites.
Schools requiring higher bandwidth can look
at ISDN, broadband or satellite etc. This can be expensive
for more remote schools and the costs for each need to be
investigated carefully.
