The document discusses how utilizing both licensed and license exempt spectrum can significantly boost network capacity and user experience to meet growing traffic demands. It summarizes the Small Cell Forum's work in providing industry guidance on leveraging both types of spectrum through small cell deployments and integration with Wi-Fi. This includes addressing challenges of an integrated heterogeneous network and recommendations for architectures that enable technologies like LTE-LAA and LWA across small cells and Wi-Fi access points. The Small Cell Forum continues working groups to further develop these capabilities and their practical deployment.

Editor's Notes
- #7: Doc 064.05.01 Wi-fi/Cellular radio co-existence in enterprise products Doc 094.05.1.02 LTE-LAA: At its best with small cells Doc 097.05.1.01 Small Cells and License Exempt Spectrum, Carrier Wi-Fi, Wi-Fi Calling, LAA and LWA Doc 089.05.01 Integrated Small Cell Wi-Fi by SCF and WBA Doc 063.05.02 Small Cell and Wi-Fi Coverage Study
- #8: This is part of the ongoing collaboration between the Small Cell Forum (SCF) and Wireless Broadband Alliance (WBA) in the area of integrated Small-Cell Wi-Fi (ISW) networks. The first white paper provided an overview of the various ISW network architectures and highlighted various deployment aspects. It was then observed that an important part of the architecture, namely the Trusted WLAN that connects the Wi-Fi access points, access controllers and 3GPP-defined gateways (TWAG/TWAP), was not being addressed by any standards development organization (SDO) or by any industry body. So, SCF-WBA Joint Task Force (JTF) took up the task of examining and documenting the architectural options, interfaces and deployment aspects of the TWAN.
- #9: Smart Enterprise: SCF is bridging the gap between operators and Enterprise. We are accelerating demand by addressing challenges and requirements and delivering real world enterprise deployment stories, technical & rollout advice for operators & IT teams, and multi-operator business models.
