This design guide provides engineering guidelines and practical techniques for designing, planning, and implementing a wireless LAN WLAN within a high density environment in a university or college campus. Highdensity is defined as any environment with a large concentration of users, such as a classroom, lecture hall, or auditorium where the users are connected wirelessly, sharing applications and using other network services individually. This document is intended for wireless network design engineers responsible for designing, deploying, and maintaining todays Wi Fi networks. Knowledge of Cisco networking concepts, WLAN technology fundamentals, Cisco Unified Wireless Network CUWN features and configurations are prerequisites. Cisco Mobility 4. Design Guide.

The demands on WLANs for functionality and scalability are growing due to the rapid proliferation of new network devices and applications. The number of devices and connections per user is steadily increasing. It is common for most users today to not only have a primary computing device but also at least one other smart device. Wireless operators have worked hard to accommodate the increased demand for data services over wireless networks. They have been forced to consider alternative offload strategies, including wirelessly connecting electronic devices Wi Fi. Unfortunately, the majority of smartphones being introduced into the marketplace only support Wi Fi at 2. Gigahertz GHz, which is rapidly increasing pressure on Wi Fi designers and administrators to design products for the smallest segment of bandwidth available. This trend has driven a dramatic increase in user densities, with many users competing for 2. GHz services. According to some projections, this competition for resources has just begun. In addition to this rapid increase in demand for an already congested spectrum, new network devices often are designed for use in the home. This is often not well suited for optimal efficiency in an engineered public wireless space. Administrators are finding themselves faced with the challenge of providing ever increasing levels of service in areas where simple pervasive coverage was the singular design goal. Simply adding more access points APs often does not enhance service. This design guide focuses on the challenges facing administrators deploying WLANs in higher education and offers practical strategies and design guidance for evaluating and modifying current deployment strategies, improving performance with existing resources, and successfully scaling network accessibility in high density venues. The best practices discussed have been gathered from multiple venues and have been used to successfully deploy high density wireless networks throughout the world. While the guide primarily focuses on requirements for a large, network connected lecture hall, the principles discussed will provide the reader with the tools necessary to successfully increase density in a wide variety of other shared network environments. While there have been great advances made in the speed and ease of implementation of Wi Fi networks, the basic nature of radio frequency RF is generally unchanged. Increasing the number of users who can access the WLAN in a small physical space remains a challenge. The steps and process for a successful high user density WLAN design that can be proven, implemented, and maintained using Ciscos Unified Wireless Network architecture is detailed. It includes these general steps    Plan Determine application and device requirements such as bandwidth, protocols, frequencies, service level agreement SLA, etc.    Design Determine density, cell sizing, antennas, coverage, site survey, etc.    Implement Install, test, tune, establish baseline, etc.    Optimize Monitor, report, adjust, review baseline for SLA.    Operate Cisco Wireless Control System WCS monitoring, troubleshooting tools, capacity monitoring and reporting tools, etc. The general concepts underlying high density Wi Fi design remain true for many environments. But it is important to note that the content and solutions presented here will not fit every WLAN design scenario. Rather, the intent of the guide is to explain the challenges in WLAN design for high density client environments and to offer successful strategies so that engineers and administrators understand them and are able to articulate the impact design decisions will have. High density WLAN design refers to any environment where client devices will be positioned in densities greater than coverage expectations of a normal enterprise deployment, in this case a traditional, carpeted office. For reference, a typical office environment has indoor propagation characteristics for signal attenuation. User density is the critical factor in the design.
