Building a mixed bandwidth wireless infrastructure around Bristol.
The bottom line actions are:
- Cliff/Henk to map the coverage characteristics of 802.11 around the Merchant Venturers
- David to talk to Mike Walker of Vodafone
- Phil to write up notes and put Art Galleries grant proposal together
- Ed & Huw to talk to John Waters about GPRS possibilities
If you don't recognise these I may have made them up in the excitement of the meeting
but they look like a likely bunch of actions given the notes.
The goal of the meeting was to create a plan to install a wireless infrastructure
around Bristol that could be used to support the development and testing of wearable and
wireless e-service ideas.
We decided that it would be sensible/feasible to grow the area covered by 802.11 base
stations as the project matured starting with a small footprint of social hotspots around
the university and @Bristol. We need a map to show the areas to be covered and we need to
understand the coverage characteristics of the initial target areas to know what the
profile of base station distribution will be. Our initial thoughts were that we would be
starting with somewhere between 10 and 20 base stations.
We had some discussion about connecting the base stations to the university's wired
infrastructure and David pointed out that the BCTN cableran from the centre of town out to
the downs via the university and Whiteladies Rd. The distribution of university buildings
around the area we intend to cover also makes the connection of the base stations into the
wired network simple.
The initial list of places to cover would eventually be determined by interviewing
student to identify social hotspots but out 1st pass list was:
- Students' Union
- Art Gallery (up from MVB)
A brainstorming of applications dug up some new thoughts and some old chestnuts, all
worthy of trying out once the infrastructure is in place. Two main categories were
suggested; Student Need and Public Need. I think the former was extended to University
Need meaning anyone who works or visits the university. The brainstormed list of
application areas was:
- Find a friend - A stranger is just a friend I haven't yet got to know
- Student and staff induction - Where am I supposed to be now? How do I get to ..?
- Community belonging/talking statues "Hey how you doin' Dave? I'm Giovanni. You can
call me John. Have I told you about my New World trip? See ya"
- Virtual Graffiti 'Don't have today's special in here unless you like it HOT'
- Exhibit animation - augmented reality gallery
- 'Zag-me' - offers from retailers in the next hour
- Voice over IP - exactly what it says on the tin
- Video over IP - ditto
- Location-based Games (initial ideas: virtual paint ball, D&D, Bristol Doom) - Huw
has a UCL student working in a related area.
- Message relay (person to person area networks)
We need to:
- interview students about social hotspots
- know how well .11 performs at the locations we have identified.
- determine how many base stations and their locations
- identify routes into the university network
- buy the cards and base stations
- buy the Jornadas (next gen 548s or 720s?)
- enlist students to help install the base stations
- install .11 apps server(s)
- recruit students to carry out final year and other projects (Oct/Nov for final year
thoughts on projects)
- enlist @Bristol for support and brainstorming @Bristol ideas (not the 10th item but can
be parallel strand)
- enlist GPRS service provider (again needs to be done early but not a showstopper for
- sort out who is paying for what (should be done early but not necessary to get started)
Technology Research questions:
- Charging models for .11 networks
- Cellphone network as authentication system (and charging system?)
- Trusted applications
- Privacy/Rights management
- Ad-hoc network management
- Integrating wireless infrastructures
- Context aware service architecture
- Wearable vs portable
- Tailored vs soldered
- Real and physical links (modelling,interfacing,synchronising, registration)
- Augmenting reality
- Location sensing anytime, anywhere
- Sensor fusion and being context aware
- Interaction design (HCI)
- Personal area networking (detect and play)

One last note:
Henk and Cliff are getting the .11 cards and base station to map the coverage in the
MVB. We in HP need to see if we can supply them with a 720 or earlier Jornada to plug the
cards into. Various people are away next week so normal service will resume the week of
