WiFi plans for January

We have continued to monitor our WiFi service across the Campus over the last couple of months and I’m aware that whilst it has now improved for many people, there are still some people having difficulty in using the WiFi network. Our own engineers have been testing the performance regularly across the Campus and gathering information on specific issues, and we have been working closely with the manufacturer throughout this period. We know that there are issues connecting some types of device, some issues when people move from one Campus location to another, and some specific areas of the Campus where people are consistently having more difficulty connecting to WiFi than other areas. On the plus side, we can see from our system monitors that there typically two to three thousand successful connections being made by people at any point in time during the day.

We have now reviewed the issues we are seeing with the manufacturer, and are getting support from very senior level within the company. We have agreed an action plan with them and they will be placing engineers on our Campus week commencing 5th January to carry out a complete review of our entire installation, and as part of that to make some specific changes that we have agreed. There will be some outages during the first week in January, but we anticipate these will be short.

Our own engineers and the manufacturer will carry out an initial assessment of the impact of this work over the first half of January. With such a large user population and range of devices it will be important that we do further checks after that so that we can be confident that we have resolved the issues people are experiencing and have a stable and reliable service across the Campus. We’ll do this by asking a group of staff and students in the first instance to keep a more detailed diary of their use of WiFi – when it works and when/where they have problems.

We are giving a high priority to resolving the remaining issues on WiFi and will work through this as quickly as we can. Please do keep providing feedback via our Helpdesk, visit the Georgina Scott Sutherland Learning Centre or contact us via ITHelpdesk@rgu.ac.uk if you need any help meantime.

WiFi

I outlined in a previous blog post the work we have carried out over the last several months to improve the WiFi service on Campus. We’ve been carefully monitoring the service since the start of semester, and over the first few weeks it performed well and we were seeing it handle a much higher load of users successfully when compared to the same period last year. We had good feedback from those users we were in contact with.

I’m aware, however, that over the past two weeks in particular there have been some problems which have affected people trying to connect to Eduroam over WiFi on our Campus. Once they are connected, the connection is good and performs well, but there have been a number of reports of people not being able to connect from time to time. The problem seems to be that the attempt to connect either hangs, or says that it can’t connect, or asks for a password.

IT Services engineers have raised this as a high priority issue with the manufacturer, and they currently have an engineer on site from Europe backed up with specialist advice from the USA. They are able to trace what is happening on the system and are currently working on a number of options to address the situation. I’m sorry that people are experiencing some problems at the moment – we know how important the WiFi service is and we have stressed to the manufacturer the urgency of getting our WiFi system back to a stable state as quickly as possible.

If you do encounter difficulties in connecting meantime, the tips provided in the previous blog post may still be useful to help you get connected.

Wi-Fi Access for the new Session at RGU

It’s now the beginning of September and time to restart the IT Blog after a bit of a break over the summer. It might have been a break as far as the blog is concerned, but it has been a busy period of time for IT Services. For the first blog post of the new Session I thought I would update you on some of the changes we have been making to the Wi-Fi system on Campus.

Last year we rolled out a new system, based on “eduroam”. For many people it worked well from the outset, but we know from feedback that others had problems connecting to Wi-Fi, especially in the earlier part of the Session. We also know that we did not have sufficient Wi-Fi cover in all parts of the campus and this was frustrating for people trying to connect in areas where there was a poor signal.

I’d like to start with a reminder on how to connect and the key benefit of “eduroam.” If you look at the Wi-Fi networks available on campus you should see two in particular:

RGU_Connect
eduroam

The very first time you connect any device to our Wi-Fi, you should use RGU_connect. This will ask you to enter your RGU username and password, and will guide you through a series of steps to automatically set up your device to connect to the eduroam Wi-Fi service. Don’t try to set up the eduroam service manually – it won’t work.

After you have done this, you should not normally need to use RGU_Connect on that device again. Please don’t try to configure RGU_Connect to use as your main Wi-Fi network- it is not designed for this, and you will prevent others from being able to log in. Once you have completed the initial setup, your device should from then on automatically connect to the eduroam service. If you have more than one device, then you will have to go through RGU_Connect once on each device you wish to use.

You will find full instructions for all the main device types in the IT Help Desk website.

You may find when moving around the Campus that eduroam occasionally drops the signal so that it can reconnect to the Wi-Fi access points in your new location – sometimes this can take a minute or two but it should connect again automatically. If your device for any reason is not connecting, try turning Wi-Fi off for a minute or so and then back on.

If you find that your device does not automatically connect to eduroam or you are having persistent problems connecting, then please do contact the IT Help Desk for assistance. It’s important for us to know if people are having specific problems so that we can resolve them.

Eduroam is an International service used by Universities and Colleges across the world. This means that once you have successfully set up your device to connect to eduroam at RGU, it will also automatically connect to eduroam at any other University or college in the UK or the world that uses eduroam. You don’t need to do anything else to set this up. In summary, eduroam is your normal Wi-Fi service when you are on our Campus or visiting another institution.

We are aware that some “apps” on mobile platforms do not work fully across our Wi-Fi system. We do not block any apps deliberately, but we believe that the design of some apps is such that they do not operate across some of the network management tools that we use, in common with many other large organisations. We are continuing to look at what we can do to alleviate this.

As far as coverage goes, we have been installing additional access point across all of our campus buildings. This is a major piece of work which has been taking place over the summer, and should be completed by the start of Semester. This means that you will get a good wireless signal inside most areas in our buildings.

Quick update on IT

Wow, where does the time go? I haven’t posted on the Blog since February – that’s bad, sorry about that. There has been lots happening since then, so here is a quick general update.

On Wireless, we still had a few problems with the new system but we have had great feedback from students through Facebook and face-to-face and this has really helped IT Services to identify and work through some of the problems. As I said in January, we can see from our logs that large numbers of people have been able to connect and use the system successfully, but we knew from feedback that quite a few were still having problems. We’ve worked with the manufacturer and have made a number of changes to the controllers and feedback from students now is that it is greatly improved. We still have to extend the coverage to ensure that all areas on the Campus are covered, and that is now planned for the summer.

We have been looking at the “old Library” area in the Aberdeen Business School and are right now finalising plans to put in more IT workstations, a help point, AV facilities, and better group work areas for students to use. IT Services along with Estates are just in the process of finalising cost estimates, and hopefully that will be approved and the work will commence in the near future.

Behind the scenes, IT Services are working hard on preparations to move our St Andrew Street datacentre. We moved one of our datacentres last year to the shared datacentre at University of Aberdeen and now we are moving the other one. It’s going into a new facility which we are also sharing with the University of Aberdeen so by the summer we will have all of our server kit in two new state of the art datacentres, each with environmentally friendly cooling and generator backup. We are moving ourselves too – once we get the datacentre out of St Andrew St the three remaining departments will move out of there and we will have to disconnect all the IT and remove the building from our Campus network. St Andrew St has been one of our main “hubs” for IT since IT began, so this is very much going to be the end of an era!

This is the time of year when Schools and Departments submit their planning statements for the forthcoming year and we are also looking at all of the IT related project requests so that we can update our forward plans. These are all going through the approval process as I write, and once things are finalised I’ll put a summary on the blog. Some of the key areas we are likely to be looking at are:

– A major investment in our storage and server infrastructure to replace end of life equipment and increase capacity and performance;
– Improvements to our Learning tools, including an upgrade to Moodle and improvements to access to Library e-resources
– Enhancements to our portfolio of communication tools to provide new video conference facilities across the Campus, more flexible access to telephony services and integrated access to Skype communications;
– Enhancements to the Staff and Student portal (RGyoU), particularly looking at the provision of more information for students in one place, and better document management and collaborative tools for staff;
– A new system for managing student placements
– Preparation for the opening of the new Scott Sutherland School of Architecture at Riverside East

These are just a few highlights – just as importantly we plan to spend some considerable time on preparatory work for initiatives which will start the following year, but more of that later.

Update on Wireless Service

First of all, a Happy New Year to all staff and students at RGU! This blog has been a bit quiet last few weeks so new year resolution is to put more out on the blog.

Back in August, I gave an update on our plans for improving the wireless service on our Garthdee campus. Our plan then was to install the new service, based on “Eduroam”, in Riverside East and the refurbished space in Aberdeen Business School, followed by a rollout to the rest of the Campus to replace the previous system. We had hoped that the previous system would have been able to operate for an interim period of time until we completed the full rollout of Eduroam, but unfortunately it continued to cause problems from the start of Semester.

So, we decided to quickly replace all the wireless access points on the old system so that Eduroam is now the only wireless system on Campus. We also installed additional access points in the refurbished ABS Foyer and that has greatly improved the cover there.

However, we don’t yet have wireless coverage across all areas on Garthdee and we are working to extend this over the next few months. At the moment, the whole of Riverside East is covered, the open central areas in Aberdeen Business School, and Faculty of Health and Social Care are covered, Sports Centre and a number of open areas and meeting rooms in the other buildings. Until we get the cover extended, you may find some rooms where the wireless signal is not strong enough to give you a good connection – it’s not broken, it’s just that we haven’t yet brought the new system to these areas.

We know that WiFi is an important service for our users. Students, as usual, have a wonderful way of expressing their service requirements and one of the Class Reps shared this little pyramid with me – thanks!

IT Services can see from the system logs that many people are using WiFi without any difficulty, but at the end of last year there were a number of people reporting some problems. Remember, there’s good support material which you can find online on the IT Helpdesk’s support pages.

We made a change in December as recommended by the supplier to address some problems in connectivity and “roaming”. What’s “roaming”, you may ask? Well, when your device connects to a wireless network it connects to a wireless access point (transmitter) close to you. If you move around the building, the system has to release you from the original access point and connect you to another one. Technically, that’s a complex process and sometimes, it can take a minute or two for that to settle down, so if you are finding problems with WiFi as you move around, allow the system a bit of time.

Some people have been confused by “RGU Connect” – you only use RGU Connect once, and what it does is configure all the settings on your device. Once you’ve done that, your device should automatically connect to eduroam from then on. Please don’t try to use RGU Connect as your main WiFi – it causes problems for other people trying to connect, and anyway won’t work very well.

IT Services also found last year that some devices worked better than others – this appears to relate to the manufacturer and the operating system – whether its Microsoft, Android or Mac. IT Services hope that the change made in December will have improved these issues but are continuing to monitor and work with the supplier on this.

Some apps that have worked in the past aren’t working fully. Some of these IT Services have been able to fix, others, are more difficult to diagnose. I am aware that Facebook Apps work on some devices but not on others – this is not a University policy to block Facebook!!! IT Services are continuing to work to resolve these issues, although some of this is dependent on getting information from the people that wrote the apps.

When you visit other eduroam campuses (in Aberdeen you can access it at Aberdeen University and NHS teaching hospitals) you will need to turn off “proxy” settings to allow you to use the service there (remember to note what they are before you turn them off!) then switch the proxy settings back on when you come back to RGU – they are normally “proxy.rgu.ac.uk”.

And finally (!) – if you are running a conference or event, remember that IT Services can provide guest logins for the WiFi. Only guests from other Universities will be able to use eduroam, and even then only if their University supports it.

Connected Aberdeen

Aberdeen and the surrounding regions are widely recognised as a global energy hub and a substantial contributor to the economy. Aberdeen was the only major UK city to grow during the last recession, oil and gas exports are around £7billion annually and 11 of Scotland’s top 25 companies are located in the region.

Driven by the vibrant commercial and residential sectors, there is a growing demand for digital connectivity in the area. There is also a recognition that currently it is behind the curve in the deployment of next generation broadband and that connectivity overall is not in keeping with the region’s role as a global energy hub.

Aberdeen City Council and Aberdeenshire Council are working in partnership on an initiative called “Accelerate Aberdeen” to improve digital connectivity within the City and the immediately surround regions. Late last year it was announced that Aberdeen City had been awarded over £5m from the UK Government “Urban Broadband Fund” to become a ‘Super Connected City’. This is being taken forward in a number of distinct strands and Aberdeen City Council have engaged early on with the two Universities in the city and with North East of Scotland College to ensure that they are involved.

One of the strands is called a “wireless concession” and has been launched as a public tender . Aberdeen City Council wants to see significantly improved mobile and wireless coverage across the city. To achieve this, the Council will allow the successful bidder to use the Council’s lampposts, bus stops, and buildings across the City to install the necessary infrastructure to provide 4G mobile coverage, and WiFi in key areas. It’s fantastic that the Council have recognised the importance of this to the educational institutions in the city. Between the two Universities and the College we probably have over 30,000 learners in the city – the vast majority of whom will rely heavily on good mobile and wireless coverage for communication and accessing modern digital learning resources. Anything that improves connectivity across the city will benefit the learner and research communities and their interaction with enterprises across the city.

Formally, this procurement covers assets owned by Aberdeen City Council. It might also be possible to extend this in a similar way to assets owned by the Universities and the College in order to improve coverage on our campuses, but we’ll need to wait until early 2014 to talk to the successful bidder and see what might be possible here. Will keep you posted.

Wi-Fi and Eduroam

Commissioning of the Wi-Fi system in the Riverside East building and Aberdeen Business School started on 14th August and will continue through to the 27th September. The service will initially be focussed on the Library tower, followed by the rest of Riverside East and finishing with the redeveloped are of Aberdeen Business School.

The initial service will cover Windows devices and apple phones and mobile devices. Other devices (e.g. android and Macs) will be added as commissioning continues.

Further details on the commissioning of wi-fi are available on RGyoU. Follow the link and enter your username and password to access the page.

Staff and students at RGU will be pleased to know that as part of implementing this new Wi-Fi system we will be implementing “Eduroam”. What is Eduroam? Very simply, it is a worldwide arrangement whereby staff from one academic institution can, when they are visiting another academic institution, log in to the wireless network at the other institution, but do so using the username and password they normally use at home. So, staff or students at RGU can visit other participating institutions and log in with their RGU username and password.

Likewise, visitors to RGU from other participating institutions can sign on to the RGU wireless network using their own username and password.

The key benefit is that when you are visiting another institution, you don’t need to request a “guest” username and password, you can just log straight in. It works on laptops and mobile devices, and some institutions may allow you to connect to their wired network as well if you need to.

We are implementing Eduroam as part of the implementation of the new wireless network this summer. This wireless network will be implemented in Riverside East first, and then Aberdeen Business School as part of its refurbishment, and then later in the year in the rest of the Campus. When the new wireless system is up and running, the SSID will just be called “eduroam”. This means that we will also be using Eduroam for the normal wireless access for our own staff and students on Campus – it’s easier just to have one system.

For a few months, we will be operating with two wireless systems. Buildings other than Riverside East and Aberdeen Business School will continue to run the current wireless system until it is fully replaced. However, as soon as Eduroam is available in Riverside East you will be able to use it at other participating institutions if you happen to be visiting them.

Before you can actually use Eduroam, there will be some things to check and configure on your own equipment, you will need to comply with Eduroam and institutional policies, and you’ll need to enter your username in a particular way – but more details of all of that will be issued nearer the time. There’s loads of information available about Eduroam, but a good place to start is on the Janet web site .

If you are looking to see where you can use Eduroam, you will see that each institution can be listed as a “Home” or “Visited” institution, or both. You want to look for institutions listed as “Visited” – these are the ones which will allow you to log in when you visit them.

There’s also an amusing animation which you can view to get an easy understanding of what Eduroam is about.

Wireless Coverage at RGU

We’ve had a few issues with our wireless network over the past few weeks – apologies for that to our staff and students. Without going into the details, there were a number of unexpected issues with the central controllers and we’ve been in regular contact with the supplier and manufacturer to get these sorted. We still have some background work to do in order to get to the root cause of the issues, but we have an interim solution in place now and the service itself is much more stable for our users. We are, as it happens, shortly going to install a new Wireless Network Infrastructure anyway to meet the requirements of the new Riverside East building down at Garthdee, and to meet the growth in demand for coverage across the whole of the Garthdee Campus.

Use of wireless networks, as we all know, has exploded over the last few years to the point where we increasingly take it for granted that we will have wireless access in many public spaces and places of work. In designing our “Riverside East” new building down at the Garthdee Campus, we were clear from the outset that we wished to see wireless coverage available within the entire building. Our current wireless infrastructure varies across the Campus. When it was first implemented, the intention was to make sure that the key “public” areas were wireless enabled, including the core committee rooms, library and teaching areas. But, it was not designed to be a complete solution – especially in our older buildings it did not at the time make sense to attempt to put wireless coverage into every single room.

Requirements change, however, and with the range of mobile devices in use today complete wireless coverage is now a growing expectation, and we are receiving requests for the wireless service to be extended to areas that currently have poor coverage. As mentioned above, we are starting the process of refreshing our wireless network with the new Riverside East building in the first instance. We need to get that building commissioned as our first priority, but whatever solution we procure for that will be sized so that it can be expanded across to the rest of the Campus.

Installing a wireless network in a large building with thousands of users is a complex task. Wireless signals are broadcast by what we call “wireless access points” – you’ve probably seen them on the wall around the campus. Each access point can only handle a limited number of connections without losing performance, and it must not be too close to another access point using the same radio frequency, and there is a limited number of radio frequencies that by law we are allowed to use. So, we have to position the access points across the building (vertically as well as horizontally) to match what we think the demand will be in each area and configure them so that they don’t interfere with each other. To achieve that, we need to calculate how far each signal will broadcast and that depends on the construction materials used in the building. Early on in the design of the building, we put the CAD drawings through a software programme which calculates how the wireless signal will behave theoretically and we use that to estimate where the access points should go. That is only an approximate guide, however, and once the building is complete engineers have to physically walk through the building to measure the actual signal loss in each area before they can finalise where all the access points should go.

Even having done all of that, there are still some limitations on wireless technology. If you are doing heavy downloads of large files, and particularly if there are a number of people doing that in the same physical location, you may find that the wireless network will slow down – that’s just the laws of physics and how much traffic can be carried across one radio signal in one location. That said, we are looking at newer wireless technologies that will improve performance even in areas of dense use. So, while there might still be some occasions where it is better to “plug in”, for most everyday tasks – email, web browsing, Facebook usage etc the new wireless network will be fine.
