Ryerson Wireless Service Renewal and Expansion

Introduction

Since the 2007-2008 academic year, increasing use of smartphones and laptops on campus has resulted in dramatically increased demand for wireless services. Even where wireless service had been provided to cover high-use areas like the Library and TRSM, at times (especially in the Winter 2012 term), the number of devices has overwhelmed the available access points(radios). Some access point models are only able to handle roughly 30 wireless connections at a time but may receive over 100 concurrent connection requests. In response, CCS has been increasing the number of wireless access points across campus and is replacing older models with newer and more capable ones. This page provides information on Ryerson’s expanding wireless network as well as some background information on wireless use on campus.

Wireless Expansion and Renewal

The following table shows a total number of wireless access points at the end of a particular period available to campus starting prior to March 2012.

*During the Fall 2013 term CCS undertook a major network infrastructure upgrade in TRS that includes replacing wireless access points with new series 220 access points. The new devices can support more connections and provide greater bandwidth - especially in high demand areas.

Access Point Upgrades

Ryerson began installing the Aruba Networks 60 series access points in 2004 and has since moved to installing series 130 access points in low-to-medium demand areas and series 220 access points in higher demand areas. The following table provides a rough comparison between the different types of access points.

Access point model capacity

Model 325 Series 220 Series 130 Series 100 Series
Max Connections 100 100 70 30
Max Shared Bandwidth Available 1.3 Gbps 950 Mbps 450 Mbps 300 Mbps
Standard a/b/g/n/ac a/b/g/n/ac a/b/g/n a/b/g/n

Note: the actual number of connections and bandwidth available on an access point will vary depending on factors like distance to the access point, radio interference, and bandwidth demands from each wireless device.

Even under near ideal circumstances wireless bandwidth is normally shared between many devices and is rarely as good as a wired connection. If you have access to a wired connection in an office or classroom podium CCS strongly recommends you use the wired connection for the best possible reliability and performance.

Increasing Demand for Wireless

The following table shows the year-by-year increase in the peak number of wireless devices simultaneously connected to Ryerson’s wireless network.

2008 - 2009 2,500
2009 - 2010 4,500
2010 - 2011 6,000
2011 - 2012 7,000
2012 - 2013 9,200
2013 - 2014 9,636
