§ Provide 3G indoor solution for a university campus
§ Typical building with open-plan area with café, quiet study rooms &
offices, coverage area approximately 1700sqm, 500 staff/students
§ Existing indoor Cisco Wi-Fi AP deployment, using modular 36/37xx
Access Points, with university delivering students free Wi-Fi
connectivity
§ Focus of use case then is to enable the university to provide great 3G
voice connectivity

§ The Wi-Fi deployment model can work successfully for deploying small
cells – leveraging pre-existing Wi-Fi APs, mounting locations,..
§ Utilizing a common IT infrastructure, including PoE/LAN, keeps CapEx
and OpEx costs down
§ SCF-068 recommendations are being used to deploy Small Cells in a
shared enterprise LAN environment
QoS, 802.1X/MAC Authentication, IP addressing, ….
§ Traffic isolation is a key enterprise requirement for security and guest
access, and is working today
