Introduction
• Previous experience: developing the existing ‘UHI Network’
• www.uhi.net.uk• My current project: re-implementation of
the UHI Regional Education & Research Network – ‘the UHI NGN’
• www.uhi.ac.uk/lis/projects/ngn

Topics of Discussion
• Our experience of Satellite Internet Access
• Our experience of line-of-sight wireless• Why the use of these technologies by
UHI is limited…• and• What niche can these technologies fill
for UHI?

UHI characteristics
UHI and its colleges have under 20,000 HE and FE students on around 100 sites across the region …About 5 ‘big’ sites – which are small in UK termsAbout 50 ‘medium’ – very small in UK termsAbout 45 ‘small’ – fewer than 10 PCs
All these sites are there because the communities they serve are small and remote; some are very small and very remote.
UHI Economics do not add up due to the spread of our small user base over a large number of sites.

UHI Network requirement
- Big sites need plenty of bandwidth, in the 100Mbps class
- Medium sites also need plenty of bandwidth if possible, but 10Mpbs if that is all we can afford
- Small sites need whatever we can get for them, but budget is very limited

The UHI Approach
Use a small range of ‘standard’ solutionsThis keeps things manageableAllows for an equipment pool
UHI owns all the CP equipment involvedWe can self-maintain, recycle, manageCollect all the work into one placeStaff training concentrated into fewer heads

A-End: Sabhal Mòr Ostaig, looking south to Mallaig and the Ardnamurchan Peninusla. Go to the CalMac website to see when the ferry will be visible

Wireless Example
We never got that working reliably but …The equipment can be re-used elsewhere;We didn’t spend too much time on it
thankfully despite the ferry journey between the ends;
We keep looking at this again because Wireless is obviously the right thing to do.

How does Satellite fit in at UHI?
Is this is just a way to provide ‘broadband’?
What is the USP …Quality: ‘better than ISDN’ ?Or price: ‘cheaper than MegaStream’ ?
A standard item for our service portfolio ?Or a special: ‘Solution of last resort’ ?

The Big Questions
Is higher quality & bandwidth of terrestrial service worth the extra cost?Internal telephone service seen as very valuableStandard product for our service portfolio
Would sites stick with Satellite if they have to pay?

The Big Answers
Is even better service worth the extra cost?Only one of the five eventually upgraded to
anything better at their own costWould sites stick with Satellite at trial end?
Three downgraded to ISDN on cost groundsAnother two stayed with satellite because:
(1) new building due soon; wanted to delay hassle of change but then avoid move charges.
(2) ISDN seen as too unreliable in very remote location, although actual use extremely low.

UHI NGN project
Core funded this time• - ability of individual sites no longer such
a big problem• - overall affordability is now the big issue• - this issue is now centrally managed• - I spend more time on fund-raising than
most ‘technical’ project managers would expect to have to!

UHI NGN Project (2)
• Budget of around 5million Euro over 5 years, servicing nearly 100 sites, with significant ERDF support.
• Four major sub-projects:• -- Bandwidth contracts• -- Router and LAN core equipment• -- Telephony integration and extension• -- Ubiquitous Wi-Fi service
![Page 33: Jem Taylor UHI Millennium Institute · The JISC Satellite Trial. UHI deployed Satellite links at 5 sites. All were ‘ISDN replacement’ projects for the duration of the trial. Kept](https://reader034.vdocuments.mx/reader034/viewer/2022042413/5f2cb752ea5a6967bc63abe3/html5/thumbnails/33.jpg)
UHI NGN Bandwidth
Contract placed with Telco for service to most sites
- MPLS IP-VPN using RFC1917 addressing
- Terrestrial circuit at 40+ sites, speeds from 5 Mbps up to 200 Mbps
- Private ADSL solution at about 40 very small sites, using ADSL technology to deliver IP-VPN cheaply
- Wireless IP backbone connections in Western Isles
- Private line-of-sight wireless is a niche solution for fewer than a dozen sites

UHI NGN Bandwidth (2)
Some sites are suited to line-of-sight connection – but really very few
Even when line-of-sight possible, the second site is typically small and Private ADSL solution may be cost-effective

What This Means (1)
Satellite ‘works’ but has the wrong performance characteristics
- Not much use for H.323 VC or VoIP- Far too expensive- Inherently a niche solution which can
never get market ‘traction’
![Page 36: Jem Taylor UHI Millennium Institute · The JISC Satellite Trial. UHI deployed Satellite links at 5 sites. All were ‘ISDN replacement’ projects for the duration of the trial. Kept](https://reader034.vdocuments.mx/reader034/viewer/2022042413/5f2cb752ea5a6967bc63abe3/html5/thumbnails/36.jpg)
What This Means (2)
Line-of-sight ‘works’ but far too few sites are suitable
- Very cost-effective
- Need locations nearer to one another
- Good for multi-sector partnerships with several sites in the same town
