چکیده
Executive Summary The growth in the number of Wi-Fi devices accessing the network in concentrated areas, along with limitations in shared spectrum, requires a new approach to provide the best predictable and scalable user experience. The goal of this white paper is to provide the technical details behind Cisco's unique approach to high-density Wi-Fi design, Cisco ® High Density Experience (HDX), which offers both hardware and software innovation delivered in the Cisco Aironet ® 2700 and 3700 Series access points. With the emergence of smartphones, tablets, and laptops built for IEEE 802.11ac, which can use 80-MHz channel bandwidth, and more complex modulation and coding schemes, the challenges that result from rapidly increasing deployments of both Wi-Fi clients and Wi-Fi networks and the concurrent growing usage of shared spectrum become more acute. This paper explores the underlying factors for high-density Wi-Fi scenarios and describes Cisco HDX. It also explains how this suite establishes a foundation and growth path for addressing and overcoming both the ongoing and imminent challenges of high-density Wi-Fi. Finally, this paper also discusses recent HDX enhancements that can be used to achieve higher levels of spectrum efficiency and end user performance.

This white paper addresses the RF interference challenges that result from high usage of a shared spectrum. With the introduction of the IEEE’s latest wireless standard, 802.11ac, with its 80-MHz-wide channel bandwidth, these challenges become more acute. It explores the limitations of standard Wi-Fi chip design and how this affects the ability of an IT organization to gather critical, actionab...
متن کاملCisco SON for Small Cells: Reduce OpEx and Improve Quality of Experience White Paper
You are probably deploying different types of small cells from multiple vendors, including residential small cells, indoor small cells for buildings, and public small cells in indoor hotspots. Most 3G small cells today are passive in operation they do some auto-configuration on start-up but can’t react to changes in traffic or in their radio environment. Others, such as Cisco Universal Small Ce...
