Back in the early noughties I remember attending edtech conferences and the wifi failing to cope with the number of delegates. That wasn’t surprising, they were often using a single wireless access point and when sixty plus edtech delegates hit the event with their laptops and PDAs it wasn’t much of a surprise to find the lone access point failing to deliver any wifi.
Even today I have been to events where the wifi struggles as delegates with their laptops, iPads, smartphones connect to the wifi. It is partly about the number of devices, it is also about how they are using the connection, refreshing twitter, uploading photographs, streaming video like Periscope. I also think that some people may take advantage of the fast connection (sometimes inadvertently) to download updates, podcasts and video.
At the recent UCISA Spotlight on the Digital Capabilities event in Birmingham, the conference centre wifi, which in theory could cope with 250 wireless clients, failed to deliver a stable consistent wifi connection. I found that if my laptop was connected to the wifi, it not only took time to get a connection, but every so often the connection would drop. I would say that when I had a connection it was fast and consistent. I felt lucky that I could still tweet and upload photographs using my phone on my Three 4G connection. I was getting over 60Mb/s on that connection in the main auditorium. I was quite pleased that the seats in the auditorium had tables and power sockets.
The thing is, a conference with delegates from the edtech world are probably going to melt the wifi as most conference centres don’t plan their capacity on the extremes. For most events it probably works just fine. Personally since those early days I have come less and less to rely on the conference wifi, using a 3G dongle, 3G tethering, a 4G WiFI Hotspot to my current 4G tethering. This means that not only do I not worry so much about melting wifi, but it frees up the bandwidth for somebody else, and I think I might a pretty heavy user of bandwidth!
