I have been starting to plan a strategy for online document management for my staff and students. We are implementing a new Wifi network in my district. I plan on creating a guest SSID just as i did in my previous district. I wrote about that in a previous post.

My plan is to allow faculty and students to be able to bring in their own mobile devices. In order for this to be successful I want them to have access to their documents while on and off the network. Setting up the guest SSId for internet only is the easy part. I need to find a solution for accessing documents over the web. This will ensure they will not have to be added to our domain to get to their files.

There are of course a number of options these days. Google Apps for Education, Zoho and other open source document management platforms are available. In the case of Google Apps it is a major change.  My biggest obstacle is that Google Apps uses email as its primary communication and collaboration tool. There are many concerns with providing email accounts to our students. While the details of this are another post it is a noteworthy concern.

Microsoft has recently introduced Office Web Apps. You can access the beta called Microsoft Office Live currently. It provides the ability to access word, powerpoint and excel documents online. You can even share and collaborate on them. I have heard that office 2010 will offer the ability to host this online cloud on your own servers. I am hoping that if hosted authentication can be handled with LDAP.  This might be a solution for us. It is of course a very expensive solution in comparison to Google Apps. The good news is we are already paying for it with our MS volume license.

Here is a quick blurb about MS Office Live.

Office Web Apps, the online companion to Word, Excel®, PowerPoint® and OneNote® applications, allow you to access documents from anywhere. You can even simultaneously share and work on documents with others online. View documents across PCs, mobile phones, and the Web without compromising document fidelity. Create new documents and do basic editing using the familiar Office interface. By offering more ways to access files from almost anywhere, Office Web Apps enable you to get things done according to your schedule.

I will continue to look into an open source solution that we can load onto our servers. If anyone has a recommendation I would love to hear it!

Allowing faculty members and students to bring their laptops to school is the most cost effective way to get to 1 to 1. In most districts this is not an option. There is concerns about management of the laptops, virus and botnet attacks as well as network intrusions.

While these are all very valid concerns I believe that they can be addressed through infrastructure configurations. There are both old and new technologies that can control client access on a network which would eliminate most of these concerns. We have been successful in our district by making some minor configurations and an investment in infrastructure.

We implemented a managed wireless network. These networks are available from Cisco, Meru, Aruba, Trapese, Ruckus, and a few other. This type of network allows all of the access ponts to be managed by a controller. ON this wireless network we broadcast two SSID (these are the names of the wireless networks that the computers can see and connect to). One is for internal users (our school owned computers) and the other is for guests.

We segment our network in virtual lans (vlans). What that means in simple terms it that each network port is assigned to a group. Each group has different access and rights. This allows the students to not interrupt the admin network for example.

On our wireless network we assigned the SSID Guest to the Vlan Guest. By configuring Access Rules in our switches we have limited the guest account to only have access to the internet. They can not access anything else on the network. If a student brings in a laptop with a virus the virus is contained to that machine only. Because of the access rules and the vlans the virus cannot access any of our servers. This is how we allow teachers and students who bring their own laptops in to connect.

With all of the amazing web2.0 sites and tools available access to the internet only really does not limit what the student and teacher can accomplish. A $400 netbook and the guest internet access can go a long way.

In our network we have a Cisco 4507R Core Switch and HP Procurve switches at the access level. We have a vlan for admins, teachers, student, printers, computer lab, wifi and wifi guests. We use a MERU ABGN wireless network.

Please remember that the more computers you have accessing the internet the more bandwidth you will need. If you are concerned about students managing files you need to look into a web based classroom management solution. Moodle or schoolwires are two examples. Flash drives are also a good option. 

This is a simple explanation of how to setup your network. It should be designed by an IT professional. Just realize that most of these technologies already exist on your network. The required investment in infrastructure is significantly less then purchasing a laptop for every student.
