Good evening - I would like to know if any of your institutions is implementing a new strategy for deploying wireless services on campus. With the explosion of mobile devices, the demand for wireless services has skyrocketed. At University of Houston we are using Meru as the provider for implementation of our wireless access network. Both Meru and Aruba are strong competitors in the high-density Wi-Fi network arena. Does any of your institutions use either Meru or Aruba technologies? Would you be willing to share your current Wi-Fi implementation strategies, experiences, and your network design standards? Have you used services from vendors to do site surveys in your institutions? Thanks in advance for any info you can provide.

 Rita,

The explosion of BYOD creates high density situations that can only be addressed with MORE APs in the space.  The ipads and other devices do not have the same send/receive capabilities as laptops - requiring a stronger signal from the APs - Those two requirements work against you due to the limited 2.4Ghz channel selections of 1-6-11 - you cannot just turn up the power to reach the devices without creating interference.  I have been advising clients for years to push every device possible to the 5.8Ghz band - more channels means more APs in the same space without interference.   I design for -66dB signal strength and >25dB sig to noise ratio.  This will accommodate VoWiFi as well as the ipads.  Don't forget stairwells, elevators and mechanical spaces.   A lot of HVAC equipment is now WiFi capable (although in the 2.4 Ghz band due to battery life issues).  

Hope that helps
