Re: [WIRELESS-LAN] Typical Registration Numbers for Guest Wireless Service?

[Hinojosa,Rafael]

Drexel University is a global research university, w/ roughly 77 acres in an 
urban environment (Philadelphia), near a major transportation hub (30th St 
Station), w/ a neighboring University (UPenn) a few blocks away, that sees a 
lot of foot traffic.  I’d like to highly recommend you remember to take your 
environment & immediate surroundings into consideration as you forecast & 
receive stats from others.

We implement an open guest SSID for both sponsored & non-sponsored guest.  The 
open SSID has a captive portal that contains both guest & sponsored-guest logon 
forms, as well as a link to our 802.1x installation wizard (XpressConnect) for 
students, faculty, & staff w/ a current university user ID.  Guests (sponsored 
& non-sponsered) end up on a NAT’ed network that isn’t a part of the official 
University network.  Access is controlled by OpenDNS.  Non-sponsored guest can 
get access by simply providing a properly formatted e-mail address (no 
verification or self-registration).  Non-sponsored guests are bandwidth 
limited, 3mb down / 1mb up.  “Re-authentication” is required w/ every 
association & after 8 hours of continuous use.  Short term sponsored guests are 
provisioned by networking staff (a simple username & password combo).  
Sponsored guest are not bandwidth limited but still end up in the same 
non-university IP space.

I’m not 100% sure I trust these numbers, but they seem to be consistent for the 
past 3 days.  We see about 100,000 association (sessions, or “any instance in 
which a user connects to the network”) per day, from about 9000 unique devices 
(transient, roaming devices).  Only ~1200 devices / users bother logging in & 
they generate between 18000 - 16000 sessions, & about 220 gigabytes of traffic 
(between 80 - 85% of total guest traffic).  Sponsored Guest usage varies, it 
depends on if an event’s being held or not & the size of event participants.




Hope this helps,

—Raf

For those implementing a guest wireless service for sponsored and/or 
non-sponsored guests,

Is anyone able to share stats on the quantity of guest registrations over a 
time period, a daily average or the like?

We are working to forecast the load for a new non-sponsored guest wireless 
service, your insight is most appreciated!

Our device registrations are good for a period of 7 days.  On average we see 
~1000-1100 registration events per day on a weekday during the school year.  We 
peak at about 2000 simultaneous devices on the guest wireless network on those 
days, with ~8000 unique devices seen per week.
