How we provided free WiFi at a tech conference for 900+ delegates

Apart from great organisation, speakers, and coffee, conference delegates generally rate WiFi connectivity as one of the most important needs at a conference. So, while the word spread that the number of registered Net Prophet delegates (Net Prophet is a South African conference we sponsor) was fast approaching the 900 mark, we were meticulously plotting how we were going to provide free WiFi; whilst trying to figure out exactly how many devices would be connected on the day, and at any given time.

From last year’s conference (400 delegates), we learnt that balancing the load across eight 1mb/s connections was simply not going to cut it this time. We needed to find something that would allow 900+ delegates to freely tweet, upload, download, check emails, send emails and chat to their friends who were missing out on the conference.

Some of the challenges that face conference WiFi are:

1. Providing enough back-haul Internet capacity
2. Limiting per user download and upload speed
3. WiFi coverage within the venue
4. Wireless interference
5. Wireless Access Point congestion

Net Prophet takes the form of a one day conference held in a large conference facility. We calculated that we would need an Internet back-haul link total with the capacity of about 20Mb/s down and 10Mb/s up to give the largely tech crowd a great experience. We provisioned this directly from our Data Centre in Cape Town via 2 5.8Ghz point to point wireless links to the roof of the conference venue.
